usfuck google_auth_exception：错误获取oauth2访问令牌，消息：＆＃x27; invalid_client：未授权＆＃x27;

Question

有人可以帮助我，因为在尝试将我的应用与Google日历链接时，我会遇到错误。

我得到错误：

致命错误：未被发现的Google_auth_exception：错误获取OAuth2访问令牌，消息：'invalid_client：未经授权'in/web/htdocs/www.assiweb.cloud/home/home/home/myproject/mmyproject/google/google/auth/auth/oauth/oauth2.php:132 堆栈跟踪： ＃0/web/htdocs/www.assiweb.cloud/home/myproject/google/google/client.php(128）：google_auth_oauth_oauth2-2-＆gt; authenticate（'4/0ax4x4x4xfwin-ucy ...''，false） ＃1/web/htdocs/www.assiweb.cloud/home/myproject/includes/calendar.php(24）：google_client-＆gt; authenticate（'4/0ax4x4xfwin-ucy ...''4/0ax4xfwin-ucy ...''）。

当我遇到错误时客户端上的代码是：

 public function authenticate($code, $crossClient )
{
 $this->authenticated = true;
   return $this->getAuth()->authenticate($code, $crossClient);
   }

以及我在calendar.php中获得错误的代码（第24行）是：

 $client->authenticate($_GET['code'],true);

这些代码行不是由我写的，但是我必须解决此问题，我不知道来自Google Oauth的很多东西，有人可以帮助我如何解决它或给我一个完整的工作代码如何将我的应用程序与Google帐户链接到使用日历。

听起来您不正确地将授权应用于客户。尝试检查一下。

require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/Oauth2Authentication.php';

// Start a session to persist credentials.
session_start();

// Handle authorization flow from the server.
if (! isset($_GET['code'])) {
    $client = buildClient();
    $auth_url = $client->createAuthUrl();
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
    $client = buildClient();
    $client->authenticate($_GET['code']); // Exchange the authencation code for a refresh token and access token.
    // Add access token and refresh token to seession.
    $_SESSION['access_token'] = $client->getAccessToken();
    $_SESSION['refresh_token'] = $client->getRefreshToken();    
    //Redirect back to main script
    $redirect_uri = str_replace("oauth2callback.php",$_SESSION['mainScript'],$client->getRedirectUri());    
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

function getOauth2Client() {
    try {
        
        $client = buildClient();
        
        // Set the refresh token on the client. 
        if (isset($_SESSION['refresh_token']) && $_SESSION['refresh_token']) {
            $client->refreshToken($_SESSION['refresh_token']);
        }
        
        // If the user has already authorized this app then get an access token
        // else redirect to ask the user to authorize access to Google Analytics.
        if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
            
            // Set the access token on the client.
            $client->setAccessToken($_SESSION['access_token']);                 
            
            // Refresh the access token if it's expired.
            if ($client->isAccessTokenExpired()) {              
                $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
                $client->setAccessToken($client->getAccessToken()); 
                $_SESSION['access_token'] = $client->getAccessToken();              
            }           
            return $client; 
        } else {
            // We do not have access request access.
            header('Location: ' . filter_var( $client->getRedirectUri(), FILTER_SANITIZE_URL));
        }
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}
