“Google MC Funnels API” (401 Unauthorized)

Question

我设置了一个MC漏斗的例子，一切都很好！！：

• 从 git 下载了大师。
• 放一个帐户，它有效！
• 没关系！返回给我一些书籍样本的结果...

所以，我输入新代码来获取"mcf："，但收到" 401 未经授权">

问题：如何/在哪里授权查询"mcf：xxxxxxxx"指标和尺寸？

我使用的代码：

include_once __DIR__ . '/../vendor/autoload.php';
include_once "templates/base.php";
// $client->setApplicationName("Client_Library_Examples");
// $client->setScopes(['https://www.googleapis.com/auth/books']);    //not sure here..
// $service = new Google_Service_Books($client);
   $service = new Google_Service_Analytics($client);      //not sure here..
        $mcf = $service->data_mcf(
            'ga:80456636',
            '2015-02-22',
            '2015-02-23',
            'mcf:totalConversionValue',
            array(
                'dimensions' => 'mcf:source,mcf:medium'
            )
        );
        echo"<pre>";
        var_dump($mcf);
        echo"</pre>";

Answer 1

首先，

您注释掉了$client的所有代码。 Google 图书是一个公共 API，这意味着您可以使用公共 API 密钥进行身份验证。 Google Analytics数据是私人数据，这意味着您需要使用Oauth2或服务帐户。

服务帐户示例

   require_once 'Google/autoload.php';
   session_start();     
/************************************************   
 The following 3 values an befound in the setting   
 for the application you created on Google

    $client_id = '[Your client id]';
    $Email_address = '[YOur Service account email address Address]';     
    $key_file_location = '[Locatkon of key file]';      
    $client = new Google_Client();      
    $client->setApplicationName("Client_Library_Examples");
    $key = file_get_contents($key_file_location);    
    // seproate additional scopes with a comma   
    $scopes ="https://www.googleapis.com/auth/analytics.readonly";  
    $cred = new Google_Auth_AssertionCredentials($Email_address,         
                             array($scopes),        
                             $key);     
    $client->setAssertionCredentials($cred);
    if($client->getAuth()->isAccessTokenExpired()) {        
         $client->getAuth()->refreshTokenWithAssertion($cred);      
    }       
    $service = new Google_Service_Analytics($client);
$mcf = $service->data_mcf->get('ga:80456636',
            '2015-02-22',
            '2015-02-23',
            'mcf:totalConversionValue',
            array(
                'dimensions' => 'mcf:source,mcf:medium'
            )
        );
        echo"<pre>";
        var_dump($mcf);
        echo"</pre>";
