PK gF'Z[쉱� � recaptcha/CONTRIBUTING.mdnu �[��� # Contributing
Want to contribute? Great! First, read this page (including the small print at
the end).
## Contributor License Agreement
Before we can use your code, you must sign the [Google Individual Contributor
License
Agreement](https://developers.google.com/open-source/cla/individual?csw=1)
(CLA), which you can do online. The CLA is necessary mainly because you own the
copyright to your changes, even after your contribution becomes part of our
codebase, so we need your permission to use and distribute your code. We also
need to be sure of various other things—for instance that you'll tell us if you
know that your code infringes on other people's patents. You don't have to sign
the CLA until after you've submitted your code for review (a link will be
automatically added to your Pull Request) and a member has approved it, but you
must do it before we can put your code into our codebase. Before you start
working on a larger contribution, you should get in touch with us first through
the issue tracker with your idea so that we can help out and possibly guide you.
Coordinating up front makes it much easier to avoid frustration later on.
## Linting and testing
We use PHP Coding Standards Fixer to maintain coding standards and PHPUnit to
run our tests. For convenience, there are Composer scripts to run each of these:
```sh
composer run-script lint
composer run-script test
```
These are run automatically by [Travis
CI](https://travis-ci.org/google/recaptcha) against your Pull Request, but it's
a good idea to run them locally before submission to avoid getting things
bounced back. That said, tests can be a little daunting so feel free to submit
your PR and ask for help.
## Code reviews
All submissions, including submissions by project members, require review.
Reviews are conducted on the Pull Requests. The reviews are there to ensure and
improve code quality, so treat them like a discussion and opportunity to learn.
Don't get disheartened if your Pull Request isn't just automatically approved.
### The small print
Contributions made by corporations are covered by a different agreement than the
one above, the Software Grant and Corporate Contributor License Agreement.

PK gF'Z���h� � recaptcha/ARCHITECTURE.mdnu �[��� # Architecture
The general pattern of usage is to instantiate the `ReCaptcha` class with your
secret key, specify any additional validation rules, and then call `verify()`
with the reCAPTCHA response and user's IP address. For example:
```php
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->setExpectedHostname('recaptcha-demo.appspot.com')
->verify($gRecaptchaResponse, $remoteIp);
if ($resp->isSuccess()) {
// Verified!
} else {
$errors = $resp->getErrorCodes();
}
```
By default, this will use the
[`stream_context_create()`](https://secure.php.net/stream_context_create) and
[`file_get_contents()`](https://secure.php.net/file_get_contents) to make a POST
request to the reCAPTCHA service. This is handled by the
[`RequestMethod\Post`](./src/ReCaptcha/RequestMethod/Post.php) class.
## Alternate request methods
You may need to use other methods for making requests in your environment. The
[`ReCaptcha`](./src/ReCaptcha/ReCaptcha.php) class allows an optional
[`RequestMethod`](./src/ReCaptcha/RequestMethod.php) instance to configure this.
For example, if you want to use [cURL](https://secure.php.net/curl) instead you
can do this:
```php
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret, new \ReCaptcha\RequestMethod\CurlPost());
```
Alternatively, you can also use a [socket](https://secure.php.net/fsockopen):
```php
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret, new \ReCaptcha\RequestMethod\SocketPost());
```
## Adding new request methods
Create a class that implements the
[`RequestMethod`](./src/ReCaptcha/RequestMethod.php) interface. The convention
is to name this class `RequestMethod\`_MethodType_`Post` and create a separate
`RequestMethod\`_MethodType_ class that wraps just the calls to the network
calls themselves. This means that the `RequestMethod\`_MethodType_`Post` can be
unit tested by passing in a mock. Take a look at
[`RequestMethod\CurlPost`](./src/ReCaptcha/RequestMethod/CurlPost.php) and
[`RequestMethod\Curl`](./src/ReCaptcha/RequestMethod/Curl.php) with the matching
[`RequestMethod/CurlPostTest`](./tests/ReCaptcha/RequestMethod/CurlPostTest.php)
to see this pattern in action.
### Error conventions
The client returns the response as provided by the reCAPTCHA services augmented
with additional error codes based on the client's checks. When adding a new
[`RequestMethod`](./src/ReCaptcha/RequestMethod.php) ensure that it returns the
`ReCaptcha::E_CONNECTION_FAILED` and `ReCaptcha::E_BAD_RESPONSE` where
appropriate.

reCAPTCHA is a free CAPTCHA service that protects websites from spam and abuse.
This is a PHP library that wraps up the server-side verification step required
to process responses from the reCAPTCHA service. This client supports both v2
and v3.
- reCAPTCHA: https://www.google.com/recaptcha
- This repo: https://github.com/google/recaptcha
- Hosted demo: https://recaptcha-demo.appspot.com/
- Version: 1.2.4
- License: BSD, see [LICENSE](LICENSE)
## Installation
### Composer (recommended)
Use [Composer](https://getcomposer.org) to install this library from Packagist:
[`google/recaptcha`](https://packagist.org/packages/google/recaptcha)
Run the following command from your project directory to add the dependency:
```sh
composer require google/recaptcha "^1.2"
```
Alternatively, add the dependency directly to your `composer.json` file:
```json
"require": {
"google/recaptcha": "^1.2"
}
```
### Direct download
Download the [ZIP file](https://github.com/google/recaptcha/archive/master.zip)
and extract into your project. An autoloader script is provided in
`src/autoload.php` which you can require into your script. For example:
```php
require_once '/path/to/recaptcha/src/autoload.php';
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
```
The classes in the project are structured according to the
[PSR-4](http://www.php-fig.org/psr/psr-4/) standard, so you can also use your
own autoloader or require the needed files directly in your code.
## Usage
First obtain the appropriate keys for the type of reCAPTCHA you wish to
integrate for v2 at https://www.google.com/recaptcha/admin or v3 at
https://g.co/recaptcha/v3.
Then follow the [integration guide on the developer
site](https://developers.google.com/recaptcha/intro) to add the reCAPTCHA
functionality into your frontend.
This library comes in when you need to verify the user's response. On the PHP
side you need the response from the reCAPTCHA service and secret key from your
credentials. Instantiate the `ReCaptcha` class with your secret key, specify any
additional validation rules, and then call `verify()` with the reCAPTCHA
response and user's IP address. For example:
```php
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->setExpectedHostname('recaptcha-demo.appspot.com')
->verify($gRecaptchaResponse, $remoteIp);
if ($resp->isSuccess()) {
// Verified!
} else {
$errors = $resp->getErrorCodes();
}
```
The following methods are available:
- `setExpectedHostname($hostname)`: ensures the hostname matches. You must do
this if you have disabled "Domain/Package Name Validation" for your
credentials.
- `setExpectedApkPackageName($apkPackageName)`: if you're verifying a response
from an Android app. Again, you must do this if you have disabled
"Domain/Package Name Validation" for your credentials.
- `setExpectedAction($action)`: ensures the action matches for the v3 API.
- `setScoreThreshold($threshold)`: set a score threshold for responses from the
v3 API
- `setChallengeTimeout($timeoutSeconds)`: set a timeout between the user passing
the reCAPTCHA and your server processing it.
Each of the `set`\*`()` methods return the `ReCaptcha` instance so you can chain
them together. For example:
```php
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->setExpectedHostname('recaptcha-demo.appspot.com')
->setExpectedAction('homepage')
->setScoreThreshold(0.5)
->verify($gRecaptchaResponse, $remoteIp);
if ($resp->isSuccess()) {
// Verified!
} else {
$errors = $resp->getErrorCodes();
}
```
You can find the constants for the libraries error codes in the `ReCaptcha`
class constants, e.g. `ReCaptcha::E_HOSTNAME_MISMATCH`
For more details on usage and structure, see [ARCHITECTURE](ARCHITECTURE.md).
### Examples
You can see examples of each reCAPTCHA type in [examples/](examples/). You can
run the examples locally by using the Composer script:
```sh
composer run-script serve-examples
```
This makes use of the in-built PHP dev server to host the examples at
http://localhost:8080/
These are also hosted on Google AppEngine Flexible environment at
https://recaptcha-demo.appspot.com/. This is configured by
[`app.yaml`](./app.yaml) which you can also use to [deploy to your own AppEngine
project](https://cloud.google.com/appengine/docs/flexible/php/download).

PK gF'Z��+- +- apiclient/UPGRADING.mdnu �[��� Google API Client Upgrade Guide
===============================
1.0 to 2.0
----------
The Google API Client for PHP has undergone major internal changes in `2.0`. Please read through
the list below in order to upgrade to the latest version:
## Installation now uses `Composer`
**Before**
The project was cloned in your project and you would run the autoloader from wherever:
```php
// the autoload file was included
require_once 'google-api-php-client/src/Google/autoload.php'; // or wherever autoload.php is located
// OR classes were added one-by-one
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
```
**After**
This library now uses [composer](https://getcomposer.org) (We suggest installing
composer [globally](http://symfony.com/doc/current/cookbook/composer.html)). Add this library by
running the following in the root of your project:
```
$ composer require google/apiclient:~2.0
```
This will install this library and generate an autoload file in `vendor/autoload.php` in the root
of your project. You can now include this library with the following code:
```php
require_once 'vendor/autoload.php';
```
## Access Tokens are passed around as arrays instead of JSON strings
**Before**
```php
$accessToken = $client->getAccessToken();
print_r($accessToken);
// would output:
// string(153) "{"access_token":"ya29.FAKsaByOPoddfzvKRo_LBpWWCpVTiAm4BjsvBwxtN7IgSNoUfcErBk_VPl4iAiE1ntb_","token_type":"Bearer","expires_in":3593,"created":1445548590}"
file_put_contents($credentialsPath, $accessToken);
```
**After**
```php
$accessToken = $client->getAccessToken();
print_r($accessToken);
// will output:
// array(4) {
// ["access_token"]=>
// string(73) "ya29.FAKsaByOPoddfzvKRo_LBpWWCpVTiAm4BjsvBwxtN7IgSNoUfcErBk_VPl4iAiE1ntb_"
// ["token_type"]=>
// string(6) "Bearer"
// ["expires_in"]=>
// int(3593)
// ["created"]=>
// int(1445548590)
// }
file_put_contents($credentialsPath, json_encode($accessToken));
```
## ID Token data is returned as an array
**Before**
```php
$ticket = $client->verifyIdToken($idToken);
$data = $ticket->getAttributes();
$userId = $data['payload']['sub'];
```
**After**
```php
$userData = $client->verifyIdToken($idToken);
$userId = $userData['sub'];
```
## `Google_Auth_AssertionCredentials` has been removed
For service accounts, we now use `setAuthConfig` or `useApplicationDefaultCredentials`
**Before**
```php
$client_email = '1234567890-a1b2c3d4e5f6g7h8i@developer.gserviceaccount.com';
$private_key = file_get_contents('MyProject.p12');
$scopes = array('https://www.googleapis.com/auth/sqlservice.admin');
$credentials = new Google_Auth_AssertionCredentials(
$client_email,
$scopes,
$private_key
);
```
**After**
```php
$client->setAuthConfig('/path/to/service-account.json');
// OR use environment variables (recommended)
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json');
$client->useApplicationDefaultCredentials();
```
> Note: P12s are deprecated in favor of service account JSON, which can be generated in the
> Credentials section of Google Developer Console.
In order to impersonate a user, call `setSubject` when your service account
credentials are being used.
**Before**
```php
$user_to_impersonate = 'user@example.org';
$credentials = new Google_Auth_AssertionCredentials(
$client_email,
$scopes,
$private_key,
'notasecret', // Default P12 password
'http://oauth.net/grant_type/jwt/1.0/bearer', // Default grant type
$user_to_impersonate,
);
```
**After**
```php
$user_to_impersonate = 'user@example.org';
$client->setSubject($user_to_impersonate);
```
Additionally, `Google_Client::loadServiceAccountJson` has been removed in favor
of `Google_Client::setAuthConfig`:
**Before**
```php
$scopes = [ Google_Service_Books::BOOKS ];
$client->loadServiceAccountJson('/path/to/service-account.json', $scopes);
```
**After**
```php
$scopes = [ Google_Service_Books::BOOKS ];
$client->setAuthConfig('/path/to/service-account.json');
$client->setScopes($scopes);
```
## `Google_Auth_AppIdentity` has been removed
For App Engine authentication, we now use the underlying [`google/auth`][Google Auth] and
call `useApplicationDefaultCredentials`:
**Before**
```php
$client->setAuth(new Google_Auth_AppIdentity($client));
$client->getAuth()
->authenticateForScope('https://www.googleapis.com/auth/sqlservice.admin')
```
**After**
```php
$client->useApplicationDefaultCredentials();
$client->addScope('https://www.googleapis.com/auth/sqlservice.admin');
```
This will detect when the App Engine environment is present, and use the appropriate credentials.
## `Google_Auth_Abstract` classes have been removed
[`google/auth`][Google Auth] is now used for authentication. As a result, all
`Google_Auth`-related functionality has been removed. The methods that were a part of
`Google_Auth_Abstract` have been moved into the `Google_Client` object.
**Before**
```php
$request = new Google_Http_Request();
$client->getAuth()->sign($request);
```
**After**
```php
// create an authorized HTTP client
$httpClient = $client->authorize();
// OR add authorization to an existing client
$httpClient = new GuzzleHttp\Client();
$httpClient = $client->authorize($httpClient);
```
**Before**
```php
$request = new Google_Http_Request();
$response = $client->getAuth()->authenticatedRequest($request);
```
**After**
```php
$httpClient = $client->authorize();
$request = new GuzzleHttp\Psr7\Request('POST', $url);
$response = $httpClient->send($request);
```
> NOTE: `$request` can be any class implementing
> `Psr\Http\Message\RequestInterface`
In addition, other methods that were callable on `Google_Auth_OAuth2` are now called
on the `Google_Client` object:
**Before**
```php
$client->getAuth()->refreshToken($token);
$client->getAuth()->refreshTokenWithAssertion();
$client->getAuth()->revokeToken($token);
$client->getAuth()->isAccessTokenExpired();
```
**After**
```php
$client->refreshToken($token);
$client->refreshTokenWithAssertion();
$client->revokeToken($token);
$client->isAccessTokenExpired();
```
## PHP 5.4 is now the minimum supported PHP version
This was previously `PHP 5.2`. If you still need to use PHP 5.2, please continue to use
the [v1-master](https://github.com/google/google-api-php-client/tree/v1-master) branch.
## Guzzle and PSR-7 are used for HTTP Requests
The HTTP library Guzzle is used for all HTTP Requests. By default, [`Guzzle 6`][Guzzle 6]
is used, but this library is also compatible with [`Guzzle 5`][Guzzle 5]. As a result,
all `Google_IO`-related functionality and `Google_Http`-related functionality has been
changed or removed.
1. Removed `Google_Http_Request`
1. Removed `Google_IO_Abstract`, `Google_IO_Exception`, `Google_IO_Curl`, and `Google_IO_Stream`
1. Removed methods `Google_Client::getIo` and `Google_Client::setIo`
1. Refactored `Google_Http_Batch` and `Google_Http_MediaFileUpload` for Guzzle
1. Added `Google_Client::getHttpClient` and `Google_Client::setHttpClient` for getting and
setting the Guzzle `GuzzleHttp\ClientInterface` object.
> NOTE: `PSR-7`-compatible libraries can now be used with this library.
## Other Changes
- [`PSR 3`][PSR 3] `LoggerInterface` is now supported, and [Monolog][Monolog] is used for all
logging. As a result, all `Google_Logger`-related functionality has been removed:
1. Removed `Google_Logger_Abstract`, `Google_Logger_Exception`, `Google_Logger_File`,
`Google_Logger_Null`, and `Google_Logger_Psr`
1. `Google_Client::setLogger` now requires `Psr\Log\LoggerInterface`
- [`firebase/jwt`][Firebase JWT] is now used for all JWT signing and verifying. As a result, the
following classes have been changed or removed:
1. Removed `Google_Signer_P12`
1. Removed `Google_Verifier_Pem`
1. Removed `Google_Auth_LoginTicket` (see below)
- The following classes and methods have been removed in favor of [`google/auth`][Google Auth]:
1. Removed methods `Google_Client::getAuth` and `Google_Client::setAuth`
1. Removed `Google_Auth_Abstract`
- `Google_Auth_Abstract::sign` and `Google_Auth_Abstract::authenticatedRequest` have been
replaced by `Google_Client::authorize`. See the above examples for more details.
1. Removed `Google_Auth_AppIdentity`. This is now supported in [`google/auth`][Google Auth AppIdentity]
and is used automatically when `Google_Client::useApplicationDefaultCredentials` is called.
1. Removed `Google_Auth_AssertionCredentials`. Use `Google_Client::setAuthConfig` instead.
1. Removed `Google_Auth_ComputeEngine`. This is now supported in
[`google/auth`][Google Auth GCE], and is used automatically when
`Google_Client::useApplicationDefaultCredentials` is called.
1. Removed `Google_Auth_Exception`
1. Removed `Google_Auth_LoginTicket`. Calls to `Google_Client::verifyIdToken` now returns
the payload of the ID Token as an array if the verification is successful.
1. Removed `Google_Auth_OAuth2`. This functionality is now supported in [`google/auth`][Google Auth OAuth2] and wrapped in `Google_Client`. These changes will only affect applications calling `Google_Client::getAuth`,
as the methods on `Google_Client` have not changed.
1. Removed `Google_Auth_Simple`. This is now supported in [`google/auth`][Google Auth Simple]
and is used automatically when `Google_Client::setDeveloperKey` is called.
- `Google_Client::sign` has been replaced by `Google_Client::authorize`. This function
now takes a `GuzzleHttp\ClientInterface` object and uses the following decision tree for
authentication:
1. Uses Application Default Credentials when
`Google_Client::useApplicationDefaultCredentials` is called
- Looks for `GOOGLE_APPLICATION_CREDENTIALS` environment variable if set
- Looks in `~/.config/gcloud/application_default_credentials.json`
- Otherwise, uses `GCECredentials`
1. Uses API Key if set (see `Client::setDeveloperKey`)
1. Uses Access Token if set (call `Client::setAccessToken`)
1. Automatically refreshes access tokens if one is set and the access token is expired
- Removed `Google_Config`
- Removed `Google_Utils`
- [`PSR-6`][PSR 6] cache is used for all caching. As a result:
1. Removed `Google_Cache_Abstract`
1. Classes `Google_Cache_Apc`, `Google_Cache_File`, `Google_Cache_Memcache`, and
`Google_Cache_Null` now implement `Google\Auth\CacheInterface`.
1. Google Auth provides simple [caching utilities][Google Auth Cache] which
are used by default unless you provide alternatives.
- Removed `$boundary` constructor argument for `Google_Http_MediaFileUpload`

# Google APIs Client Library for PHP #
The Google API Client Library enables you to work with Google APIs such as Gmail, Drive or YouTube on your server.
These client libraries are officially supported by Google. However, the libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features.
**NOTE** The actively maintained (v2) version of this client requires PHP 5.4 or above. If you require support for PHP 5.2 or 5.3, use the v1 branch.
## Google Cloud Platform
For Google Cloud Platform APIs such as Datastore, Cloud Storage or Pub/Sub, we recommend using [GoogleCloudPlatform/google-cloud-php](https://github.com/googleapis/google-cloud-php) which is under active development.
## Requirements ##
* [PHP 5.4.0 or higher](https://www.php.net/)
## Developer Documentation ##
The [docs folder](docs/) provides detailed guides for using this library.
## Installation ##
You can use **Composer** or simply **Download the Release**
### Composer
The preferred method is via [composer](https://getcomposer.org/). Follow the
[installation instructions](https://getcomposer.org/doc/00-intro.md) if you do not already have
composer installed.
Once composer is installed, execute the following command in your project root to install this library:
```sh
composer require google/apiclient:"^2.7"
```
Finally, be sure to include the autoloader:
```php
require_once '/path/to/your-project/vendor/autoload.php';
```
This library relies on `google/apiclient-services`. That library provides up-to-date API wrappers for a large number of Google APIs. In order that users may make use of the latest API clients, this library does not pin to a specific version of `google/apiclient-services`. **In order to prevent the accidental installation of API wrappers with breaking changes**, it is highly recommended that you pin to the [latest version](https://github.com/googleapis/google-api-php-client-services/releases) yourself prior to using this library in production.
#### Cleaning up unused services
There are over 200 Google API services. The chances are good that you will not
want them all. In order to avoid shipping these dependencies with your code,
you can run the `Google_Task_Composer::cleanup` task and specify the services
you want to keep in `composer.json`:
```json
{
"require": {
"google/apiclient": "^2.7"
},
"scripts": {
"post-update-cmd": "Google_Task_Composer::cleanup"
},
"extra": {
"google/apiclient-services": [
"Drive",
"YouTube"
]
}
}
```
This example will remove all services other than "Drive" and "YouTube" when
`composer update` or a fresh `composer install` is run.
**IMPORTANT**: If you add any services back in `composer.json`, you will need to
remove the `vendor/google/apiclient-services` directory explicity for the
change you made to have effect:
```sh
rm -r vendor/google/apiclient-services
composer update
```
**NOTE**: This command performs an exact match on the service name, so to keep
`YouTubeReporting` and `YouTubeAnalytics` as well, you'd need to add each of
them explicitly:
```json
{
"extra": {
"google/apiclient-services": [
"Drive",
"YouTube",
"YouTubeAnalytics",
"YouTubeReporting"
]
}
}
```
### Download the Release
If you prefer not to use composer, you can download the package in its entirety. The [Releases](https://github.com/googleapis/google-api-php-client/releases) page lists all stable versions. Download any file
with the name `google-api-php-client-[RELEASE_NAME].zip` for a package including this library and its dependencies.
Uncompress the zip file you download, and include the autoloader in your project:
```php
require_once '/path/to/google-api-php-client/vendor/autoload.php';
```
For additional installation and setup instructions, see [the documentation](docs/).
## Examples ##
See the [`examples/`](examples) directory for examples of the key client features. You can
view them in your browser by running the php built-in web server.
```
$ php -S localhost:8000 -t examples/
```
And then browsing to the host and port you specified
(in the above example, `http://localhost:8000`).
### Basic Example ###
```php
// include your composer dependencies
require_once 'vendor/autoload.php';
$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
$client->setDeveloperKey("YOUR_APP_KEY");
$service = new Google_Service_Books($client);
$optParams = array('filter' => 'free-ebooks');
$results = $service->volumes->listVolumes('Henry David Thoreau', $optParams);
foreach ($results->getItems() as $item) {
echo $item['volumeInfo']['title'], "<br /> \n";
}
```
### Authentication with OAuth ###
> An example of this can be seen in [`examples/simple-file-upload.php`](examples/simple-file-upload.php).
1. Follow the instructions to [Create Web Application Credentials](docs/oauth-web.md#create-authorization-credentials)
1. Download the JSON credentials
1. Set the path to these credentials using `Google_Client::setAuthConfig`:
```php
$client = new Google_Client();
$client->setAuthConfig('/path/to/client_credentials.json');
```
1. Set the scopes required for the API you are going to call
```php
$client->addScope(Google_Service_Drive::DRIVE);
```
1. Set your application's redirect URI
```php
// Your redirect URI can be any registered URI, but in this example
// we redirect back to this same page
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
$client->setRedirectUri($redirect_uri);
```
1. In the script handling the redirect URI, exchange the authorization code for an access token:
```php
if (isset($_GET['code'])) {
$token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
}
```
### Authentication with Service Accounts ###
> An example of this can be seen in [`examples/service-account.php`](examples/service-account.php).
Some APIs
(such as the [YouTube Data API](https://developers.google.com/youtube/v3/)) do
not support service accounts. Check with the specific API documentation if API
calls return unexpected 401 or 403 errors.
1. Follow the instructions to [Create a Service Account](docs/oauth-server.md#creating-a-service-account)
1. Download the JSON credentials
1. Set the path to these credentials using the `GOOGLE_APPLICATION_CREDENTIALS` environment variable:
```php
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json');
```
1. Tell the Google client to use your service account credentials to authenticate:
```php
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
```
1. Set the scopes required for the API you are going to call
```php
$client->addScope(Google_Service_Drive::DRIVE);
```
1. If you have delegated domain-wide access to the service account and you want to impersonate a user account, specify the email address of the user account using the method setSubject:
```php
$client->setSubject($user_to_impersonate);
```
### Making Requests ###
The classes used to call the API in [google-api-php-client-services](https://github.com/googleapis/google-api-php-client-services) are autogenerated. They map directly to the JSON requests and responses found in the [APIs Explorer](https://developers.google.com/apis-explorer/#p/).
A JSON request to the [Datastore API](https://developers.google.com/apis-explorer/#p/datastore/v1beta3/datastore.projects.runQuery) would look like this:
```json
POST https://datastore.googleapis.com/v1beta3/projects/YOUR_PROJECT_ID:runQuery?key=YOUR_API_KEY
{
"query": {
"kind": [{
"name": "Book"
}],
"order": [{
"property": {
"name": "title"
},
"direction": "descending"
}],
"limit": 10
}
}
```
Using this library, the same call would look something like this:
```php
// create the datastore service class
$datastore = new Google_Service_Datastore($client);
// build the query - this maps directly to the JSON
$query = new Google_Service_Datastore_Query([
'kind' => [
[
'name' => 'Book',
],
],
'order' => [
'property' => [
'name' => 'title',
],
'direction' => 'descending',
],
'limit' => 10,
]);
// build the request and response
$request = new Google_Service_Datastore_RunQueryRequest(['query' => $query]);
$response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request);
```
However, as each property of the JSON API has a corresponding generated class, the above code could also be written like this:
```php
// create the datastore service class
$datastore = new Google_Service_Datastore($client);
// build the query
$request = new Google_Service_Datastore_RunQueryRequest();
$query = new Google_Service_Datastore_Query();
// - set the order
$order = new Google_Service_Datastore_PropertyOrder();
$order->setDirection('descending');
$property = new Google_Service_Datastore_PropertyReference();
$property->setName('title');
$order->setProperty($property);
$query->setOrder([$order]);
// - set the kinds
$kind = new Google_Service_Datastore_KindExpression();
$kind->setName('Book');
$query->setKinds([$kind]);
// - set the limit
$query->setLimit(10);
// add the query to the request and make the request
$request->setQuery($query);
$response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request);
```
The method used is a matter of preference, but *it will be very difficult to use this library without first understanding the JSON syntax for the API*, so it is recommended to look at the [APIs Explorer](https://developers.google.com/apis-explorer/#p/) before using any of the services here.
### Making HTTP Requests Directly ###
If Google Authentication is desired for external applications, or a Google API is not available yet in this library, HTTP requests can be made directly.
If you are installing this client only to authenticate your own HTTP client requests, you should use [`google/auth`](https://github.com/googleapis/google-auth-library-php#call-the-apis) instead.
The `authorize` method returns an authorized [Guzzle Client](http://docs.guzzlephp.org/), so any request made using the client will contain the corresponding authorization.
```php
// create the Google client
$client = new Google_Client();
/**
* Set your method for authentication. Depending on the API, This could be
* directly with an access token, API key, or (recommended) using
* Application Default Credentials.
*/
$client->useApplicationDefaultCredentials();
$client->addScope(Google_Service_Plus::PLUS_ME);
// returns a Guzzle HTTP Client
$httpClient = $client->authorize();
// make an HTTP request
$response = $httpClient->get('https://www.googleapis.com/plus/v1/people/me');
```
### Caching ###
It is recommended to use another caching library to improve performance. This can be done by passing a [PSR-6](https://www.php-fig.org/psr/psr-6/) compatible library to the client:
```php
use League\Flysystem\Adapter\Local;
use League\Flysystem\Filesystem;
use Cache\Adapter\Filesystem\FilesystemCachePool;
$filesystemAdapter = new Local(__DIR__.'/');
$filesystem = new Filesystem($filesystemAdapter);
$cache = new FilesystemCachePool($filesystem);
$client->setCache($cache);
```
In this example we use [PHP Cache](http://www.php-cache.com/). Add this to your project with composer:
```
composer require cache/filesystem-adapter
```
### Updating Tokens ###
When using [Refresh Tokens](https://developers.google.com/identity/protocols/OAuth2InstalledApp#offline) or [Service Account Credentials](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#overview), it may be useful to perform some action when a new access token is granted. To do this, pass a callable to the `setTokenCallback` method on the client:
```php
$logger = new Monolog\Logger;
$tokenCallback = function ($cacheKey, $accessToken) use ($logger) {
$logger->debug(sprintf('new access token received at cache key %s', $cacheKey));
};
$client->setTokenCallback($tokenCallback);
```
### Debugging Your HTTP Request using Charles ###
It is often very useful to debug your API calls by viewing the raw HTTP request. This library supports the use of [Charles Web Proxy](https://www.charlesproxy.com/documentation/getting-started/). Download and run Charles, and then capture all HTTP traffic through Charles with the following code:
```php
// FOR DEBUGGING ONLY
$httpClient = new GuzzleHttp\Client([
'proxy' => 'localhost:8888', // by default, Charles runs on localhost port 8888
'verify' => false, // otherwise HTTPS requests will fail.
]);
$client = new Google_Client();
$client->setHttpClient($httpClient);
```
Now all calls made by this library will appear in the Charles UI.
One additional step is required in Charles to view SSL requests. Go to **Charles > Proxy > SSL Proxying Settings** and add the domain you'd like captured. In the case of the Google APIs, this is usually `*.googleapis.com`.
### Controlling HTTP Client Configuration Directly
Google API Client uses [Guzzle](http://docs.guzzlephp.org/) as its default HTTP client. That means that you can control your HTTP requests in the same manner you would for any application using Guzzle.
Let's say, for instance, we wished to apply a referrer to each request.
```php
use GuzzleHttp\Client;
$httpClient = new Client([
'headers' => [
'referer' => 'mysite.com'
]
]);
$client = new Google_Client();
$client->setHttpClient($httpClient);
```
Other Guzzle features such as [Handlers and Middleware](http://docs.guzzlephp.org/en/stable/handlers-and-middleware.html) offer even more control.

## How Do I Contribute? ##
Please see the [contributing](.github/CONTRIBUTING.md) page for more information. In particular, we love pull requests - but please make sure to sign the contributor license agreement.
## Frequently Asked Questions ##
### What do I do if something isn't working? ###
For support with the library the best place to ask is via the google-api-php-client tag on StackOverflow: https://stackoverflow.com/questions/tagged/google-api-php-client
If there is a specific bug with the library, please [file an issue](https://github.com/googleapis/google-api-php-client/issues) in the GitHub issues tracker, including an example of the failing code and any specific errors retrieved. Feature requests can also be filed, as long as they are core library requests, and not-API specific: for those, refer to the documentation for the individual APIs for the best place to file requests. Please try to provide a clear statement of the problem that the feature would address.
### I want an example of X! ###
If X is a feature of the library, file away! If X is an example of using a specific service, the best place to go is to the teams for those specific APIs - our preference is to link to their examples rather than add them to the library, as they can then pin to specific versions of the library. If you have any examples for other APIs, let us know and we will happily add a link to the README above!
### Why does Google_..._Service have weird names? ###
The _Service classes are generally automatically generated from the API discovery documents: https://developers.google.com/discovery/. Sometimes new features are added to APIs with unusual names, which can cause some unexpected or non-standard style naming in the PHP classes.
### How do I deal with non-JSON response types? ###
Some services return XML or similar by default, rather than JSON, which is what the library supports. You can request a JSON response by adding an 'alt' argument to optional params that is normally the last argument to a method call:
```
$opt_params = array(
'alt' => "json"
);
```
### How do I set a field to null? ###
The library strips out nulls from the objects sent to the Google APIs as its the default value of all of the uninitialized properties. To work around this, set the field you want to null to `Google_Model::NULL_VALUE`. This is a placeholder that will be replaced with a true null when sent over the wire.
## Code Quality ##
Run the PHPUnit tests with PHPUnit. You can configure an API key and token in BaseTest.php to run all calls, but this will require some setup on the Google Developer Console.

### Coding Style
To check for coding style violations, run
```
vendor/bin/phpcs src --standard=style/ruleset.xml -np
```
To automatically fix (fixable) coding style violations, run
```
vendor/bin/phpcbf src --standard=style/ruleset.xml
```

We appreciate any bug reports or other contributions, but please note that this issue
tracker is only for this client library. We do not maintain the APIs that this client
library talks to. If you have an issue or questions with how to use a particular API,
you may be better off posting on Stackoverflow under the `google-api` tag.
Thank you!

## Contributor License Agreements
We'd love to accept your sample apps and patches! Before we can take them, we
have to jump a couple of legal hurdles.
Please fill out either the individual or corporate Contributor License Agreement
(CLA).
* If you are an individual writing original source code and you're sure you
own the intellectual property, then you'll need to sign an [individual CLA]
(http://code.google.com/legal/individual-cla-v1.0.html).
* If you work for a company that wants to allow you to contribute your work,
then you'll need to sign a [corporate CLA]
(http://code.google.com/legal/corporate-cla-v1.0.html).
Follow either of the two links above to access the appropriate CLA and
instructions for how to sign and return it. Once we receive it, we'll be able to
accept your pull requests.
## Issue reporting
* Check that the issue has not already been reported.
* Check that the issue has not already been fixed in the latest code
(a.k.a. `master`).
* Be clear, concise and precise in your description of the problem.
* Open an issue with a descriptive title and a summary in grammatically correct,
complete sentences.
* Include any relevant code to the issue summary.
## Pull requests
* Read [how to properly contribute to open source projects on Github][2].
* Fork the project.
* Use a topic/feature branch to easily amend a pull request later, if necessary.
* Write [good commit messages][3].
* Use the same coding conventions as the rest of the project.
* Commit and push until you are happy with your contribution.
* Make sure to add tests for it. This is important so I don't break it
in a future version unintentionally.
* Add an entry to the [Changelog](CHANGELOG.md) accordingly. See [changelog entry format](#changelog-entry-format).
* Please try not to mess with the Rakefile, version, or history. If you want to
have your own version, or is otherwise necessary, that is fine, but please
isolate to its own commit so I can cherry-pick around it.
* Make sure the test suite is passing and the code you wrote doesn't produce
phpunit or phplint offenses.
* [Squash related commits together][5].
* Open a [pull request][4] that relates to *only* one subject with a clear title
and description in grammatically correct, complete sentences.
### Changelog entry format
Here are a few examples:
```
* ADC Support for User Refresh Tokens (@tbetbetbe[])
* [#16](https://github.com/google/google-auth-library-php/issues/16): ADC Support for User Refresh Tokens ([@tbetbetbe][])
```
* Mark it up in [Markdown syntax][6].
* The entry line should start with `* ` (an asterisk and a space).
* If the change has a related GitHub issue (e.g. a bug fix for a reported issue), put a link to the issue as `[#16](https://github.com/google/google-auth-library-php/issues/16): `.
* Describe the brief of the change. The sentence should end with a punctuation.
* At the end of the entry, add an implicit link to your GitHub user page as `([@username][])`.
* If this is your first contribution to google-auth-library-php project, add a link definition for the implicit link to the bottom of the changelog as `[@username]: https://github.com/username`.

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

## Description
This is Google's officially supported PHP client library for using OAuth 2.0
authorization and authentication with Google APIs.
View the [reference documentation][ref-docs].
### Installing via Composer
The recommended way to install the google auth library is through
[Composer](http://getcomposer.org).
```bash
# Install Composer
curl -sS https://getcomposer.org/installer | php
```
Next, run the Composer command to install the latest stable version:
```bash
composer.phar require google/auth
```
## Application Default Credentials
This library provides an implementation of
[application default credentials][application default credentials] for PHP.
The Application Default Credentials provide a simple way to get authorization
credentials for use in calling Google APIs.
They are best suited for cases when the call needs to have the same identity
and authorization level for the application independent of the user. This is
the recommended approach to authorize calls to Cloud APIs, particularly when
you're building an application that uses Google Compute Engine.
#### Download your Service Account Credentials JSON file
To use `Application Default Credentials`, You first need to download a set of
JSON credentials for your project. Go to **APIs & Services** > **Credentials** in
the [Google Developers Console][developer console] and select
**Service account** from the **Add credentials** dropdown.
> This file is your *only copy* of these credentials. It should never be
> committed with your source code, and should be stored securely.
Once downloaded, store the path to this file in the
`GOOGLE_APPLICATION_CREDENTIALS` environment variable.
```php
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json');
```
> PHP's `putenv` function is just one way to set an environment variable.
> Consider using `.htaccess` or apache configuration files as well.
#### Enable the API you want to use
Before making your API call, you must be sure the API you're calling has been
enabled. Go to **APIs & Auth** > **APIs** in the
[Google Developers Console][developer console] and enable the APIs you'd like to
call. For the example below, you must enable the `Drive API`.
#### Call the APIs
As long as you update the environment variable below to point to *your* JSON
credentials file, the following code should output a list of your Drive files.
```php
use Google\Auth\ApplicationDefaultCredentials;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
// specify the path to your application credentials
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json');
// define the scopes for your API call
$scopes = ['https://www.googleapis.com/auth/drive.readonly'];
// create middleware
$middleware = ApplicationDefaultCredentials::getMiddleware($scopes);
$stack = HandlerStack::create();
$stack->push($middleware);
// create the HTTP client
$client = new Client([
'handler' => $stack,
'base_uri' => 'https://www.googleapis.com',
'auth' => 'google_auth' // authorize all requests
]);
// make the request
$response = $client->get('drive/v2/files');
// show the result!
print_r((string) $response->getBody());
```
##### Guzzle 5 Compatibility
If you are using [Guzzle 5][Guzzle 5], replace the `create middleware` and
`create the HTTP Client` steps with the following:
```php
// create the HTTP client
$client = new Client([
'base_url' => 'https://www.googleapis.com',
'auth' => 'google_auth' // authorize all requests
]);
// create subscriber
$subscriber = ApplicationDefaultCredentials::getSubscriber($scopes);
$client->getEmitter()->attach($subscriber);
```
#### Call using an ID Token
If your application is running behind Cloud Run, or using Cloud Identity-Aware
Proxy (IAP), you will need to fetch an ID token to access your application. For
this, use the static method `getIdTokenMiddleware` on
`ApplicationDefaultCredentials`.
```php
use Google\Auth\ApplicationDefaultCredentials;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
// specify the path to your application credentials
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json');
// Provide the ID token audience. This can be a Client ID associated with an IAP application,
// Or the URL associated with a CloudRun App
// $targetAudience = 'IAP_CLIENT_ID.apps.googleusercontent.com';
// $targetAudience = 'https://service-1234-uc.a.run.app';
$targetAudience = 'YOUR_ID_TOKEN_AUDIENCE';
// create middleware
$middleware = ApplicationDefaultCredentials::getIdTokenMiddleware($targetAudience);
$stack = HandlerStack::create();
$stack->push($middleware);
// create the HTTP client
$client = new Client([
'handler' => $stack,
'auth' => 'google_auth',
// Cloud Run, IAP, or custom resource URL
'base_uri' => 'https://YOUR_PROTECTED_RESOURCE',
]);
// make the request
$response = $client->get('/');
// show the result!
print_r((string) $response->getBody());
```
For invoking Cloud Run services, your service account will need the
[`Cloud Run Invoker`](https://cloud.google.com/run/docs/authenticating/service-to-service)
IAM permission.
For invoking Cloud Identity-Aware Proxy, you will need to pass the Client ID
used when you set up your protected resource as the target audience. See how to
[secure your IAP app with signed headers](https://cloud.google.com/iap/docs/signed-headers-howto).
#### Verifying JWTs
If you are [using Google ID tokens to authenticate users][google-id-tokens], use
the `Google\Auth\AccessToken` class to verify the ID token:
```php
use Google\Auth\AccessToken;
$auth = new AccessToken();
$auth->verify($idToken);
```
If your app is running behind [Google Identity-Aware Proxy][iap-id-tokens]
(IAP), you can verify the ID token coming from the IAP server by pointing to the
appropriate certificate URL for IAP. This is because IAP signs the ID
tokens with a different key than the Google Identity service:
```php
use Google\Auth\AccessToken;
$auth = new AccessToken();
$auth->verify($idToken, [
'certsLocation' => AccessToken::IAP_CERT_URL
]);
```
