无法在服务器端刷新Google Calendar API的访问令牌 [英] Can't refresh access token for Google Calendar API on server side

问题描述

我在iOS上的客户端应用程序授权用户并接收访问令牌和刷新令牌，并将其发送到我的服务器，该服务器将其存储在数据库中. 服务器连接到日历并获取事件. 问题是使用刷新令牌不会以任何方式刷新访问令牌，并且会返回此错误:

My client application on iOS authorizes the user and receives the access token and the refresh token and sends it to my server, where it is stored in the database. The server connects to the calendar and get the events. The problem is that the access token is not refreshed in any way using the refresh token and this error is returned:

{ 错误":"unauthorized_client"， "error_description":未经授权" }

{ "error": "unauthorized_client", "error_description": "Unauthorized" }

public function sync($token, $expiresIn, $refreshToken, $created)
{

    $client = new Google_Client();
    $client->setApplicationName('Google Calendar Synchroniser');

    $client->setScopes(Google_Service_Calendar::CALENDAR_READONLY);
    $client->setAuthConfig('../client_secret_***************.apps.googleusercontent.com');
    $client->setAccessType('offline');
    $client->setApprovalPrompt('force');

    $client->setAccessToken(json_encode([
        'access_token' => $token, 
        'created' => $created, 
        'expires_in' => $expiresIn, 
        'refresh_token' => $refreshToken
    ], true));



    //create google calendar service
    $service = new Google_Service_Calendar($client);

    //filter for events searching
    $calendarId = 'primary';
        $optParams = array(
            'maxResults' => 10,
            'singleEvents' => true
        );

    //get events
    $results = $service->events->listEvents($calendarId, $optParams);

}
