Google Analytics仅显示1位用户的数据

Question

我正在尝试创建一个页面，其中将显示有关个人GA帐户的数据。目前，无论谁登录，都只显示1个用户数据。我不明白为什么会这样，因为我使用客户端ID与oauth2.0进行身份验证。我调用了getFirstprofileId，但无论谁登录谷歌，结果总是返回相同的id

<?php
    // Load the Google API PHP Client Library.
    require_once realpath(dirname(__FILE__).'/google-api-php-client/src/Google/autoload.php');

    // Start a session to persist credentials.
    session_start();
     $client_id = 'XXXXXXXXX';

     $client_secret = 'XXXXXXX';

     $redirect_uri = 'http://XXXXX.info/info.php';

    // Create the client object and set the authorization configuration
    // from the client_secretes.json you downloaded from the developer console.

    $client = new Google_Client();

    $client->setClientId($client_id);

    $client->setClientSecret($client_secret);

    $client->setRedirectUri($redirect_uri);

    $client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);

    $analytics = new Google_Service_Analytics($client);
