如何使用Google API PHP客户端库

google-api-php-client项目地址:https://gitcode.com/gh_mirrors/goog/google-api-php-client

项目介绍

Google API PHP客户端库是谷歌提供的一套用于访问其众多产品的APIs的PHP类库. 这个库让你能够轻松地在服务器端通过PHP调用Gmail, Google Drive, YouTube等API服务. 谷歌对这个客户端库提供了正式的支持, 并且保证修复关键性bug和安全问题.

这个客户端库支持以下语言:

  • PHP 8.0或更高版本

为了方便开发者查阅相关资料, 官方提供了详细的参考文档。

项目快速启动

下载并安装

你可以通过Composer来安装此库：

$ composer require google/apiclient:^2.0

或者, 你也可以从Releases页面下载整个包。Releases页面列出所有稳定版本的发行版。下载带有google-api-php-client-[RELEASE_NAME].zip名称的文件以获取包括该库及其依赖项在内的软件包。

解压ZIP文件并在你的项目中包含自动加载器:

require_once '/path/to/google-api-php-client/vendor/autoload.php';

基础示例

以下是使用OAuth身份验证的基本代码示例:

// 引入composer的依赖项
require_once __DIR__ . '/vendor/autoload.php';

$client = new Google_Client();
$client->setApplicationName("Your App Name");
$client->setScopes([Google_Service_Drive::DRIVE]);
$client->setAccessType('offline');
$client->setIncludeGrantedScopes(true);

// 为您的应用程序设置重定向URI
$redirect_uri = 'urn:ietf:wg:oauth:2.0:oob';
$client->setRedirectUri($redirect_uri);

如果你希望使用授权码进行认证, 需要设置$client->addScope();方法添加范围, 然后处理从授权服务器接收的授权码并交换获取访问令牌.

设置应用凭据

对于OAuth认证方式, 你需要先创建Web应用程序凭证并且将JSON凭证下载到本地目录。之后, 使用Google_Client::setAuthConfig()函数设置凭据路径:

$client = new Google_Client();
$client->setAuthConfig(__DIR__ . '/client_secrets.json');
认证示例

例如使用OAuth认证上传文件至Google云端硬盘的应用代码可参阅 examples/simple-file-upload.php.

应用案例和最佳实践

当你使用Google API PHP客户端库时, 你会遇到一些常见的应用场景以及对应的解决方案:

  1. 权限管理: 对于需要特定权限操作的API(如读写存储在Google云平台上的数据), 使用OAuth方式授权, 可以帮助控制应用的访问级别.

  2. 错误处理: 在调用API过程中, 如果遇到意外的401或403错误, 请检查你是否正确设置了所需的权限范围或是否遇到了配额限制.

  3. 资源缓存: 使用缓存策略可以减少不必要的重复请求并提高性能.

典型生态项目

目前尚未提及具体的“典型生态项目”, 但这里有一些在Google API生态中广泛使用的场景:

  1. 集成Google地图: 创建基于位置的服务, 将地理位置信息整合进你的网站或移动应用。

  2. Google云端硬盘管理: 提供文件共享及协作功能的企业级云盘系统。

  3. 视频分享与社交互动: 利用YouTube API实现视频上传、评论等功能。

这些仅是基本的使用指南和推荐示例。详细的开发步骤和更多高级特性, 请查阅具体API的官方文档或GitHub仓库中的例子文件夹(examples)中提供的详细代码示例。使用Google API PHP客户端库, 开发者能够更高效地构建创新性应用而无需过多关注底层细节。

php 开发Google支付回调验证并发货

参考主要还是Google开发者后台API讲述，对应开发，你会少走很多坑，一般app应用(sockect连接服务器)不建议使用此验证方法，因为你的公钥是放在客户端代码中的，如果你的app被破解，破解者将获得你的公钥再篡改订单信息，破解者拿到公钥后可能达到刷单目的，因为你的以上验证前提都是更具此公钥加密的。app (web)应用无需担心。Google提供了web API 接口，可使用。

[![Build Status](https://travis-ci.org/google/google-api-php-client.svg?branch=master)](https://travis-ci.org/google/google-api-php-client) # Google APIs Client Library for PHP # The Google API Client Library enables you to work with Google APIs such as Google+, 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. ## 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/GoogleCloudPlatform/google-cloud-php) which is under active development. ## Requirements ## * [PHP 5.4.0 or higher](http://www.php.net/) ## Developer Documentation ## http://developers.google.com/api-client-library/php ## 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:"^2.0" ``` Finally, be sure to include the autoloader: ```php require_once '/path/to/your-project/vendor/autoload.php'; ``` ### Download the Release If you abhor using composer, you can download the package in its entirety. The [Releases](https://github.com/google/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](https://developers.google.com/api-client-library/php/start/installation). ## 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 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](https://developers.google.com/api-client-library/php/auth/web-app#creatingcred) 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](https://developers.google.com/api-client-library/php/auth/service-accounts#creatinganaccount) 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/Google/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_Kind[removed]); $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. 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](http://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#refresh) 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`. ### Service Specific Examples ### YouTube: https://github.com/youtube/api-samples/tree/master/php ## How Do I Contribute? ## Please see the [contributing](CONTRIBUTING.md) page for more information. In particular, we love pull requests - but please make sure to sign the [contributor license agreement](https://developers.google.com/api-client-library/php/contribute). ## 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: http://stackoverflow.com/questions/tagged/google-api-php-client If there is a specific bug with the library, please [file a issue](https://github.com/google/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 do you still support 5.2? ### When we started working on the 1.0.0 branch we knew there were several fundamental issues to fix with the 0.6 releases of the library. At that time we looked at the usage of the library, and other related projects, and determined that there was still a large and active base of PHP 5.2 installs. You can see this in statistics such as the PHP versions chart in the WordPress stats: http://wordpress.org/about/stats/. We will keep looking at the types of usage we see, and try to take advantage of newer PHP features where possible. ### 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. phpunit tests/ ### 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 ```
