Google登录验证失败？

Question

您好，我尝试在不使用Google+ API的情况下实现Google登录，但遇到错误。我不了解此错误或出现此错误的原因。我正在遵循指南here。

代码：

<?php
require_once (__DIR__.'../google-api-php-client-2.2.2/vendor/autoload.php');
session_start();

$client = new Google_Client();
$client->setAuthConfigFile('client/client_secrets.json');
$redirect_uri = 'myRedirectUri';
$client->setRedirectUri('myRedirectUri2');
$client->addScope('profile');
$client->setIncludeGrantedScopes(true);
if(!isset($_GET['code'])){
    $auth_url = $client->createAuthUrl();
    header('Location: '.filter_var($auth_url,FILTER_SANITIZE_URL));
}
else{
    $client->authenticate($_GET['code']);
    $_SESSION['access_token'] = $client->getAccessToken();
    header('Location: '.filter_var($redirect_uri,FILTER_SANITIZE_URL));
}

?>

这是我遇到的错误的图片：
