使用服务帐户的Google AnalyticsAPI oauth异常"invalid_grant".两台服务器上的代码相同.只有一个有效

Question

我通过服务帐户查询Analytics API .

我已经在开发服务器上编写了代码,它没有问题.在生产服务器上运行相同的代码时,它会抛出:

Google_AuthException:刷新OAuth2令牌时出错,消息:'{"error":"invalid_grant"}'

我尝试过创建另一个服务帐户,行为是一样的.

oAuth IETF草案(http://tools.ietf.org/html/draft-ietf-oauth-v2-31)对此错误说:

     invalid_grant
           The provided authorization grant (e.g. authorization
           code, resource owner credentials) or refresh token is
           invalid, expired, revoked, does not match the redirection
           URI used in the authorization request, or was issued to
           another client.

这是我写的代码:

$GA_CLIENT_ID = 'XX.apps.googleusercontent.com';
$GA_APP_EMAIL = 'XX@developer.gserviceaccount.com';
$GA_APP_NAME = 'XX';
$GA_KEY_FILE = 'XX';

// create client object and set app name
$client = new Google_Client();
$client->setApplicationName($GA_APP_NAME); // name of your app

// set assertion credentials
$client->setAssertionCredentials(
        new Google_AssertionCredentials(
            $GA_APP_EMAIL, // email you added to GA
            array('https://www.googleapis.com/auth/analytics.readonly'),
            file_get_contents($GA_KEY_FILE)  // keyfile you downloaded
            ));

// other settings
$client->setClientId($GA_CLIENT_ID);           // from API console
$client->setAccessType('offline_access');  // this may be unnecessary?

// create service and get data
$service = new Google_AnalyticsService($client);
$result = $service->data_ga->get($ids, $startDate, $endDate, $metrics, $optParams);
return $result;

我还尝试了使用authenticatedRequest()而不是Google_AnalyticsService 建议的解决方案(https://groups.google.com/forum/?fromgroups#!topic/gs-discussion/3y_2XVE2q7U%5B1-25%5D):

$req = new Google_HttpRequest($apiUrl);
$resp = $client::getIo()->authenticatedRequest($req);
$result = json_decode($resp->getResponseBody(), true);

此替代方案也适用于开发服务器,但不适用于生产服务器.

我对这一点完全无能为力.有谁见过这个/修好了吗？

谢谢!

显然问题是系统时间关闭.通过NTP同步:

sudo ntpdate npt.ubuntu.com

sudo ntpdate pool.ntp.org

编辑

正如下面提到的@RafaSashi,pool.ntp.org服务器更可靠.使用它代替ntp.ubuntu.com (这是我尝试的第一个工作,因此是最初的选择).
