Question

我正在运行以下PHP代码，使用此处的客户端库：https://code.google.com/p/google-api-php-client/。我没有为这些代码得到任何错误，但是当我调用getAccessToken()时，它返回null。

我已允许在个人日历上访问此服务帐户，并已通过API控制台授予对项目的完全访问权限。

有什么想法吗？

require_once 'google-api-php-client/src/Google_Client.php';

const CLIENT_ID = 'blahblahblah';
const SERVICE_ACCOUNT_NAME = 'blahblahblah@developer.gserviceaccount.com';
const KEY_FILE = 'path/to/privatekey.p12';

$google_client = new Google_Client(); // created only to initialized static dependencies
$client = new Google_OAuth2(); // you really just need Google_OAuth2

$key = file_get_contents(KEY_FILE);  

$client->setAssertionCredentials(
    new Google_AssertionCredentials(
        SERVICE_ACCOUNT_NAME,
        array('https://www.googleapis.com/auth/calendar'),
        $key
    )
);

var_dump($client->getAccessToken());

出于某种原因，这似乎有效：

require_once 'google-api-php-client/src/Google_Client.php';

const CLIENT_ID = 'blahblahblah';
const SERVICE_ACCOUNT_NAME = 'blahblahblah@developer.gserviceaccount.com';
const KEY_FILE = 'path/to/privatekey.p12';
const CALENDAR_SCOPE = "https://www.googleapis.com/auth/calendar";

$key = file_get_contents(KEY_FILE);
$auth = new Google_AssertionCredentials(
    SERVICE_ACCOUNT_NAME,
    array(CALENDAR_SCOPE),
    $key
);

$client = new Google_Client();
$client->setScopes(array(CALENDAR_SCOPE));
$client->setAssertionCredentials($auth);
$client->getAuth()->refreshTokenWithAssertion();
$accessToken = $client->getAccessToken();

$client->setClientId(CLIENT_ID);

如果有人可以解释为什么这有效，请编辑此答案或评论！

使用服务帐户，getAccessToken（）返回null
