我正在开发一个使用 Google Cloud Storage 的应用程序。我想使用 JSON_API 来管理上传/下载我们用户提供的图片。我的目标是使用我的服务帐户方法获取 access_token,并将其传递给 JSON_API JavaScript 客户端 api。
这是我用来获取 access_token 的花哨的裤子类:
<?php
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_StorageService.php';
class Model_Storage_Auth
{
const CLIENT_ID = "clientid.apps.googleusercontent.com";
const SERVICE_ACCOUNT_NAME = "accountname@developer.gserviceaccount.com";
const KEY_FILE = "/super/secret/path/key.p12";
const ACCESS_TOKEN = 'access_token';
const APP_NAME = 'Fancy App';
private $google_client;
function __construct()
{
$this->google_client = new Google_Client();
$this->google_client->setApplicationName(self::APP_NAME);
}
public function getToken()
{
//return '{}';
if(is_null($this->google_client->getAccessToken()))
{
try{$this->google_client->setAccessToken(Session::get(self::ACCESS_TOKEN, '{}'));}catch(Exception $e){}
if(is_null($this->google_client->getAccessToken()))
{
$scope = array();
$scope[] = 'https://www.googleapis.com/auth/devstorage.full_control';
$key = file_get_contents(self::KEY_FILE);
$this->google_client->setAssertionCredentials(new Google_AssertionCredentials(
self::SERVICE_ACCOUNT_NAME,
$scope,
$key)
);
$this->google_client->setClientId(self::CLIENT_ID);
Google_Client::$auth->refreshTokenWithAssertion();
$token = $this->google_client->getAccessToken();
Session::set(self::ACCESS_TOKEN, $token);
}
}
return $this->google_client->getAccessToken();
}
}
我使用了 google JavaScript 示例并对其进行了一些修改以尝试添加我的实现,这里是:
<?php
$access_token = json_decode(html_entity_decode($access_token), true);
?>
