服务响应中的 json 无效

Question

我正在尝试使用 PHP API 获取我的个人资料信息，但最近几天似乎无法正常工作。

我的代码如下：

<?php
try {
    $client_id = '****************.apps.googleusercontent.com';
    $client_secret = '*********************';
    $redirect_uri = '**********************';
    $google_key = '***************';

    $client = new Google_Client();
    $client->setClientId($client_id);
    $client->setClientSecret($client_secret);
    $client->setRedirectUri($redirect_uri);
    $client->setDeveloperKey($google_key);
    $client->setAccessType('offline');
    $client->setScopes(array('https://www.googleapis.com/auth/userinfo.email','https://www.googleapis.com/auth/userinfo.profile'));
    $plus = new Google_Service_Plus($client);

    if(isset($_GET['code'])) {
        $client->authenticate($_GET['code']);
        $accessToken = $client->getAccessToken();
        $refreshToken = json_decode($accessToken)->refresh_token;
        setcookie('refresh_token', $refreshToken, (time()+60*60*24*30));
        setcookie('access_token', $accessToken, (time()+60*60*24*30));
        header('Location: ./');
        exit();
    }

    if(isset($_COOKIE['access_token']) && $_COOKIE['access_token']) {
        $refreshToken = json_decode($_COOKIE['access_token'])->refresh_token;
        $accessToken = $_COOKIE['access_token'];
        setcookie('access_token', $accessToken, (time()+60*60*24*30));
        $client->setAccessToken($_COOKIE['access_token']);
    } else {
        $authUrl = $client->createAuthUrl();
    }

    if($client->getAccessToken()) {
        $accessToken = $client->getAccessToken();
        setcookie('access_token', $accessToken, (time()+60*60*24*30));
        if(isset($plus)){
            $userInfo = $plus->people->get('me');
        }
    }

    if($client->isAccessTokenExpired() && isset($userInfo)){
        $refreshToken = $_COOKIE['refresh_token'];
        $client->refreshToken($refreshToken);
        $newtoken = $client->getAccessToken();
        setcookie('access_token', $newtoken, (time()+60*60*24*30));
        header('Location: ./');
        exit();
    }

} catch (Google_Service_Exception $gse){
    error_log($gse, 0);
} catch (Google_Auth_Exception $gae){
    error_log($gae, 0);
}
?>

我很快就会使用数据库，但我想先让它与 cookie 一起使用。我得到的错误如下：

[05-Aug-2015 20:40:36 Europe/London] exception 'Google_Service_Exception' with message 'Error calling GET https://www.googleapis.com/plus/v1/people/me?key=**********************: (403) ‹' in /home5/commodit/public_html/workflow/src/Google/Http/REST.php:110

#8 /home5/commodit/public_html/workflow/index.php(4): include('/home5/commodit...')
#9 {main}

如果我尝试使用 OAuth2 而不是 Google Plus 作为服务，我也会收到“响应无效的 json”。

感谢您的帮助！ 伯大尼

P.S - 我也尝试过“opt_params”变量，但它仍然显示无效 JSON :(

我建议查看 Google/Config.php 文件，有几个默认参数可以调整以获得针对不同问题的解决方案。

在我的情况下，我也收到了无效的 json-in-service-response，我确信凭据设置正确，我尝试运行使用 GET 协议和查询字符串传递给 Google API 的 URL，并且始终有 json 格式的完整纯文本答案，所以我查看了“disable_gzip”参数并对其进行了修改以查看更改后的行为。

'Google_Http_Request' => array(
      // Disable the use of gzip on calls if set to true. Defaults to false.
      'disable_gzip' => self::GZIP_DISABLED, //self::GZIP_ENABLED,

      // We default gzip to disabled on uploads even if gzip is otherwise
      // enabled, due to some issues seen with small packet sizes for uploads.
      // Please test with this option before enabling gzip for uploads in
      // a production environment.
      'enable_gzip_for_uploads' => self::GZIP_UPLOADS_DISABLED,
    ),

您可以为调用定义的方法的 Google_Client 配置、类属性设置不同的值。

public function setClassConfig($class, $config, $value = null)
