'Google_Exception'消息'通过身份验证后无法添加服务' [英] 'Google_Exception' with message 'Cant add services after having authenticated'

问题描述

我正在使用Oauth 2.0与Google Analytics一起开发WP插件。

我所有的认证和安全数据提取工作正常，除了这一个问题：第一次获得新的Google授权代码（例如：4 / -xbSbg ....）&验证，然后尝试调用一个新的Google_AnalyticsService（）对象，它抛出错误：

'Google_Exception'带有'验证后无法添加服务'

这是第109行： http://code.google.com/p/google-api-php-client/source/browse/trunk/src/apiClient.php?r=258

刷新调用此代码的页面后，它可以正常工作 - 即check_login（）的第一个分支可以，但身份验证调用不能正常工作。

你看到代码似乎在抱怨，因为我首先进行了身份验证，并且消息说我不应该那样做。评论&代码真的让我困惑，我的问题是什么（登录代码不是很干净，我意识到）。

重要提示：我正在使用Google Auth for Installed Apps，所以我们要求一个来自用户的授权码，并使用它来获得授权令牌。

get_option（），set_option（）& update_option（）是WP本地函数，不是问题的一部分。

这是我的代码：

  class GoogleAnalyticsStats 
 {
 var $ client = false; 
 
函数GoogleAnalyticsStats（）
 {
 $ this-> client = new Google_Client（）; 
 
 $ this->客户端 - > setClientId（GOOGLE_ANALYTICATOR_CLIENTID）; 
 $ this->客户端 - > setClientSecret（GOOGLE_ANALYTICATOR_CLIENTSECRET）; 
 $ this->客户端 - > setRedirectUri（GOOGLE_ANALYTICATOR_REDIRECT）; 
 $ this-> client-> setScopes（array（GOOGLE_ANALYTICATOR_SCOPE））; 
 
 //魔术。从Analytics Service而不是关联数组返回对象。 
 $ this-> client-> setUseObjects（true）; 
 
 
函数checkLogin（）
 {
 $ ga_google_authtoken = get_option（'ga_google_authtoken'）; 
 if（！empty（$ ga_google_authtoken））
 {
 $ this-> client-> setAccessToken（$ ga_google_authtoken）; 
} 
 else 
 {
 $ authCode = get_option（'ga_google_token'）; 
 
 if（empty（$ authCode））return false; 
 
 $ accessToken = $ this-> client-> authenticate（$ authCode）; 
 $ this-> client-> setAccessToken（$ accessToken）; 
 update_option（'ga_google_authtoken'，$ accessToken）; 
 
} 
 
返回true; 
 
 
函数getSingleProfile（）
 {
 $ analytics = new Google_AnalyticsService（$ this-> client）; 
} 
 
} 
  

解决方案

您需要在函数内移动 $ analytics = new Google_AnalyticsService（$ this-> client）; function GoogleAnalyticsStats（），最好将$ analytics变成一个成员变量。

  class GoogleAnalyticsStats 
 {
 var $ client = false; 
 var $ analytics = false; 
 
函数GoogleAnalyticsStats（）
 {
 $ this-> client = new Google_Client（）; 
 
 $ this->客户端 - > setClientId（GOOGLE_ANALYTICATOR_CLIENTID）; 
 $ this->客户端 - > setClientSecret（GOOGLE_ANALYTICATOR_CLIENTSECRET）; 
 $ this->客户端 - > setRedirectUri（GOOGLE_ANALYTICATOR_REDIRECT）; 
 $ this-> client-> setScopes（array（GOOGLE_ANALYTICATOR_SCOPE））; 
 
 //魔术。从Analytics Service而不是关联数组返回对象。 
 $ this-> client-> setUseObjects（true）; 
 
 $ this-> analytics =新Google_AnalyticsService（$ this->客户端）; 
} 
 ... 
  

现在，您可以拨打分析来自 getSingleProfile 中的API。

I am working on a WP plugin with Google Analytics, using Oauth 2.0.

All of my authentication & data pulls work fine, with the exception of this one issue: the first time I get a new Google authorization code (ex: "4/-xbSbg...." ) & authenticate, then try to call a new Google_AnalyticsService() object, it tosses back the error:

'Google_Exception' with message 'Cant add services after having authenticated'

This is on line 109: http://code.google.com/p/google-api-php-client/source/browse/trunk/src/apiClient.php?r=258

Once I refresh the page that calls this code, it works fine - ie, the first branch of the check_login() is ok, but the authentication call is not working correctly.

You see that the code seems to be complaining because I DID authenticate first, and the message says I shouldn't do that. The comment & code really have me confused what my issue is (login code not very clean yet, I realize).

IMPORTANT NOTE: I am using the Google Auth for Installed Apps, and so we are asking for an auth code from user, and using that to obtain the auth token.

get_option(), set_option() & update_option() are WP native functions that are not a part of the problem

Here is my code:

class GoogleAnalyticsStats
{
var $client = false;

function GoogleAnalyticsStats()
{       
$this->client = new Google_Client();

$this->client->setClientId(GOOGLE_ANALYTICATOR_CLIENTID);
$this->client->setClientSecret(GOOGLE_ANALYTICATOR_CLIENTSECRET);
$this->client->setRedirectUri(GOOGLE_ANALYTICATOR_REDIRECT);  
$this->client->setScopes(array(GOOGLE_ANALYTICATOR_SCOPE));

// Magic. Returns objects from the Analytics Service instead of associative arrays.
$this->client->setUseObjects(true);
}

function checkLogin()
{
$ga_google_authtoken  = get_option('ga_google_authtoken');
if (!empty($ga_google_authtoken)) 
{
        $this->client->setAccessToken($ga_google_authtoken);
}
else
{
    $authCode = get_option('ga_google_token');

    if (empty($authCode)) return false;

    $accessToken = $this->client->authenticate($authCode);
    $this->client->setAccessToken($accessToken);
    update_option('ga_google_authtoken', $accessToken);         

}   

return true;
 }

function getSingleProfile()
{
$analytics = new Google_AnalyticsService($this->client);
}

}

解决方案

You will need to move $analytics = new Google_AnalyticsService($this->client); inside function GoogleAnalyticsStats(), and preferably turn $analytics into a member variable.

class GoogleAnalyticsStats
{
  var $client = false;
  var $analytics = false;

  function GoogleAnalyticsStats()
  {       
    $this->client = new Google_Client();

    $this->client->setClientId(GOOGLE_ANALYTICATOR_CLIENTID);
    $this->client->setClientSecret(GOOGLE_ANALYTICATOR_CLIENTSECRET);
    $this->client->setRedirectUri(GOOGLE_ANALYTICATOR_REDIRECT);  
    $this->client->setScopes(array(GOOGLE_ANALYTICATOR_SCOPE));

    // Magic. Returns objects from the Analytics Service instead of associative arrays.
    $this->client->setUseObjects(true);

    $this->analytics = new Google_AnalyticsService($this->client);
  }
  ...

Now, you can make calls to the analytics API from within getSingleProfile.
