谷歌OAuth不工作

我正在尝试遵循这里的教程使用Satellizer和angularjs作为前端和后台;为后端提供社交身份验证。我有问题使用Guzzle查询用户配置文件信息:这是我的php代码在我的控制器:

$accessTokenUrl = 'https://accounts.google.com/o/oauth2/token';
    $peopleApiUrl = 'https://www.googleapis.com/plus/v1/people/me/openIdConnect';
    $params = [
        'code' => $request->input('code'),
        'client_id' => $request->input('clientId'),
        'client_secret' => 'my-client-secret',
        'redirect_uri' => $request->input('redirectUri'),
        'grant_type' => 'authorization_code',
    ];
    $client = new GuzzleHttp'Client();
    $accessTokenResponse = $client->post($accessTokenUrl, ['form_params' => $params]);
    $accessToken = json_decode($accessTokenResponse->getBody()->getContents(),true)['access_token'];
    try {
//            $profileResponse = $client->get($peopleApiUrl, ['header' => ['Authorization' => 'Bearer ' . $accessToken,]]); -->not working
            $profileResponse = $client->get($peopleApiUrl,['oauth_token'=>$accessToken]);
        } catch (RequestException $e) {
            return response()->json($e);
        }

我无法连接到获取用户配置文件和错误消息:

ClientException in Middleware.php line 69: Client error: 403

有人有同样的问题，并找到了一个方法来解决它?请帮助。谢谢。
