問題描述

我正在運行以下 PHP 代碼，使用此處找到的客戶端庫:https://code.google.com/p/google-api-php-client/.我沒有收到任何此代碼的錯誤，但是當我調用 getAccessToken() 時，它返回 null.

I am running the following PHP code, using the client libraries found here: https://code.google.com/p/google-api-php-client/. I do not get any errors for any of this code, but when I call getAccessToken(), it returns null.

我已允許在我的個人日歷上訪問此服務帳戶，并已通過 API 控制臺授予對項目的完全訪問權限.

I have allowed access to this service account on my personal calendar, and have granted full access to the project via the API Console.

有什么想法嗎?

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());

推薦答案

出于某種原因，這似乎有效:

For some reason, this seemed to work:

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);

如果有人可以解釋為什么這是有效的，請編輯此答案或評論！
