我正在使用codeigniter MVC框架登录到我的网站使用谷歌客户端库。一切都很好，除了$client->getAccessToken()时，谷歌重定向与代码，我做了以下代码。$client->getAccessToken()返回空值。这是我的代码控制器函数一。在这个函数中，我设置我的凭据创建authUrl。

public function login()
{
    // Include two files from google-php-client library in controller
    include_once APPPATH . 'third_party/google-api-php-client/vendor/autoload.php';
    
    // Store values in variables from project created in Google Developer Console
    $client_id = 'XXXXXX';
    $client_secret = 'XXXXX';
    $redirect_uri = 'path/to/mysite/login/loginGoogle';
    $simple_api_key = 'XXXXXXX';
    
    // Create Client Request to access Google API
    $client = new Google_Client();
    $client->setApplicationName("mysite");
    $client->setClientId($client_id);
    $client->setClientSecret($client_secret);
    $client->setRedirectUri($redirect_uri);
    $client->setDeveloperKey($simple_api_key);
    $client->addScope("https://www.googleapis.com/auth/userinfo.email");
    
    $authUrl = $client->createAuthUrl();
    $data['authUrl'] = $authUrl;
    
    $this->load->view('login',$data);
}

之后，当谷歌认证和重定向到我的重定向URI，这是另一个控制器功能，这是下面给出的。和问题是在这个功能。

public function loginGoogle()
{
    // Include two files from google-php-client library in controller
    include_once APPPATH . 'third_party/google-api-php-client/vendor /autoload.php';
       $client_id = 'XXXXXX';
        $client_secret = 'XXXXX';
        $redirect_uri = 'path/to/mysite/login/loginGoogle';
        $simple_api_key = 'XXXXXXX';
    
    // Create Client Request to access Google API
    $client = new Google_Client();
    $client->setApplicationName("mysite");
    $client->setClientId($client_id);
    $client->setClientSecret($client_secret);
    $client->setRedirectUri($redirect_uri);
    $client->setDeveloperKey($simple_api_key);
    $client->addScope("https://www.googleapis.com/auth/userinfo.email");
$objOAuthService = new Google_Service_Oauth2($client);
    
    // Add Access Token to Session
    if(!isset($_SESSION['access_token'])){
        
        if (isset($_GET['code'])) {
            $client->authenticate($_GET['code']);
            $token = $client->getAccessToken();                 
            $_SESSION['access_token'] = $token;
            print_r($this -> session -> userdata());exit;
            header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
        }
    }
    // Set Access Token to make Request
    if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
        $client->setAccessToken($_SESSION['access_token']);
    }
    // Get User Data from Google and store them in $data
    if ($client->getAccessToken()) {
        $userData = $objOAuthService->userinfo->get();
        $data['userData'] = $userData;
        $_SESSION['access_token'] = $client->getAccessToken();
    }}

这里，在第二个函数getAccessToken中，什么也不返回，且Google抛出expection。

看起来你从来没有得到过刷新令牌。有两种不同的令牌，访问令牌大约每隔几个小时过期一次，但刷新令牌只在重定向请求用户权限时发送一次。它需要存储在安全的地方，以便将来用于刷新访问令牌。下面是我的codeigniter代码访问Google API（这将替换loginGoogle函数中的if语句：

if($refresh_token_accessed_from_my_database) {
            //If session contains no valid Access token, get a new one
            if ($client->isAccessTokenExpired()) {
                $client->refreshToken($refresh_token_accessed_from_my_database);
            }
            //We have access token now, launch the service
            $this->service = new Google_Service_Calendar($client);
        }
        else {
            //User has never been authorized, so let's ask for the ok
            if (isset($_GET['code'])) {
                //Creates refresh and access tokens
                $credentials = $client->authenticate($_GET['code']);

                //Store refresh token for further use
                //I store mine in the DB, I've seen others store it in a file in a secure place on the server
                $refresh_token = $credentials['refresh_token'];
                //refresh_token->persist_somewhere()

                //Store the access token in the session so we can get it after
                //the callback redirect
                $_SESSION['access_token'] = $client->getAccessToken();
                $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
                header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
            }

            if (!isset($_SESSION['access_token'])) {
                $auth_url = $client->createAuthUrl();
                header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
            }

            if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
                $client->setAccessToken($_SESSION['access_token']);
                $this->service = new Google_Service_Calendar($client);
            }

如果您正在PLESK上运行，则可能需要将/var/lib/php/session上的权限更改为1777。
