Google API刷新令牌

Question

我一直在尝试在最初的几个小时内从最初的Google API调用中打印我的refresh_token（即使在取消授权和重新授权的情况下（如其他人所暗示的那样），但我仍然没有运气... API按预期工作，但我想设置更新功能，以便用户在令牌到期后不会失去访问权限（导致错误）。

目前，下面的代码将$ _SESSION ['refresh_token']设置为null。

任何帮助，因为我一直在敲我的头靠在键盘相当长的一段时间内不胜感激...

private function googleAnalyticsClient(){ 
    App::import('Vendor', 'google-api-php-client', array('file' => 'autoload.php')); 
    $client = new Google_Client(); 
    $client->setAuthConfigFile(__DIR__ . '/client_secrets.json'); 
    $client->setAccessType('offline'); 
    $client->setApprovalPrompt('force'); 
    $client->addScope('https://www.googleapis.com/auth/analytics.readonly'); 

    if (isset($_SESSION['access_token']) && $_SESSION['access_token']) { 
     $client->setAccessToken($_SESSION['access_token']); 
     $analytics = new Google_Service_Analytics($client); 
     return $analytics; 
    } else { 
     $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/dashboard/oauthcallbacks'; 
     header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL)); 
    } 
} 

public function getOauth() 
{ 
    App::import('Vendor', 'google-api-php-client', array('file' => 'autoload.php')); 

    // Create the client object and set the authorization configuration 
    // from the client_secrets.json you downloaded from the Developers Console. 
    $client = new Google_Client(); 
    $client->setAuthConfigFile(__DIR__ . '/client_secrets.json'); 
    $client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/dashboard/oauthcallbacks'); 
    $client->addScope(Google_Service_Analytics::ANALYTICS_READONLY); 

    // Handle authorization flow from the server. 
    if (! isset($_GET['code'])) { 
     $auth_url = $client->createAuthUrl(); 
     header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL)); 
    } else { 
     $client->authenticate($_GET['code']); 
     $_SESSION['access_token'] = $client->getAccessToken(); 
     $_SESSION['refresh_token'] = $client->getRefreshToken(); 
     $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/dashboard/tpstats'; 
     header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL)); 
    } 
}

在getOauth（）函数中添加以下

$client = new Google_Client(); 
$client->setAuthConfigFile(__DIR__ . '/client_secrets.json'); 
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/dashboard/oauthcallbacks'); 
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);  
$client->setAccessType('offline'); //To fetch refresh token(Refresh token issued only first time) 
$client->setApprovalPrompt('force'); //Adding this will force for refresh token
