谷歌日历API，PHP，获取刷新令牌失败-Java 学习之路

我正在尝试使用PHP中的Google Calendar API来访问一个中央帐户 . 其想法是其他用户可以向此中央帐户添加事件（他们不必登录Google帐户），因此我希望永久访问该帐户 .

首先，我做了Quickstart tutorial on Google's webpage . 我登录了我的帐户，一切都工作了一段时间 . 之后，我的访问令牌已过期，现在， $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken()); 抛出LogicException：刷新令牌必须传入或设置为setAccessToken的一部分 . 我发现 $client->getRefreshToken() 返回null .

在这里，您可以查看我的整个代码以获取Google客户端：

$client = new Google_Client();
$client->setApplicationName('Google Calendar API PHP Quickstart');
$client->setScopes(implode(' ', array(Google_Service_Calendar::CALENDAR) ) );
$client->setAuthConfig(__DIR__ . '/../config/client_secret.json');
$client->setAccessType('offline');

$credentialsPath = __DIR__ . '/../config/calendar-php-quickstart.json';
$accessToken = json_decode(file_get_contents($credentialsPath), true);
$client->setAccessToken($accessToken);

// Refresh the token if it's expired.
if ($client->isAccessTokenExpired()) {
    $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
    file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
}

知道我做错了什么吗？

尝试使用DalmTo关于Calendar API and service accounts的教程 .

这是她的指南中的刷新令牌实现：

$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {    
  $client->getAuth()->refreshTokenWithAssertion($cred);   
}

您可以测试以下代码：

// Refresh the token if it's expired.
                    if ($client->isAccessTokenExpired()) {
                        // save refresh token to some variable
                        $refreshTokenSaved = $client->getRefreshToken();

                        // update access token
                        $client->fetchAccessTokenWithRefreshToken($refreshTokenSaved);

                        // pass access token to some variable
                        $accessTokenUpdated = $client->getAccessToken();

                        // append refresh token
                        $accessTokenUpdated['refresh_token'] = $refreshTokenSaved;

                        // save to file
                        file_put_contents($credentialsPath, json_encode($accessTokenUpdated));
                    }

我将分享我最终开始工作的代码 . 我正在使用前端Web应用程序获取初始授权，然后将该代码传递给php Web服务以存储在dbase中供以后使用 .
