通过Google -api-php-client"检索Google搜索分析;图书馆 - Retrieving Google Search Analytics by "google-api-php-client" library

我仍然是任何API的初学者，所以需要帮助。据我所知，google-api-php-client库中的服务"Webmasters"允许我接收CTR, Clicks等数据

我从github下载了lib文件，并把它放在了localhost上。然后在谷歌开发者控制台我创建项目(不太明白，为什么?这个项目不包含关于网站的任何信息，其中搜索信息我需要)。然后为项目创建服务器密钥(通过"添加凭据"在Google Developers Console中，不输入任何ip)。Google Search Console API已启用。我是我的网站的完整用户(我可以看到它在谷歌搜索控制台)。我也有谷歌账号，当然，并且登录了。

在lib的examples文件夹中创建的源文件，以及其他示例:

include_once "templates/base.php";    
require_once realpath(dirname(__FILE__) . '/../src/Google/autoload.php');
$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
$apiKey = "AIzaSyCOJ56353XByxh8rCpfgfhgfhZzopSLUe"; // Value of server key, that I created in for my project ().
if (strpos($apiKey, "<") !== false) {
  echo missingApiKeyWarning();
  exit;
}
$client->setDeveloperKey($apiKey);
//here are my efforts
$service = new Google_Service_Webmasters($client);
var_dump($service->searchanalytics->query(
'http://sschesnok.com.ua',
 new Google_Service_Webmasters_SearchAnalyticsQueryRequest())); //I'm not sure about correctness of 2nd param

我看到错误:

<b>Fatal error</b>:  Uncaught exception 'Google_Service_Exception' with message 'Error calling GET https://www.googleapis.com/webmasters/v3/sites?key=AIzaSyCOJXByxh8rCpfZzopSLUerl6LjWmziqhw: (401) Login Required' in    G:'server'www'gwt'gs'src'Google'Http'REST.php:110

(401) Login Required -我错在哪里?我需要通过什么登录和在哪里?

第二个问题-我需要把什么作为第二个参数传递给query方法?

请帮我弄清楚:从这个库中检索搜索信息。我从来没有使用过任何API，所以对它几乎一无所知。

这是我的工作代码。我使用的是dev-master版本的这个库。

include_once "templates/base.php";
session_start();
require_once realpath(dirname(__FILE__) . '/../src/Google/autoload.php');
$client_id = '**********************.apps.googleusercontent.com';
$client_secret = '*******************';
$redirect_uri = 'http://localhost/gwt/gr/examples/user-example.php';
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/webmasters");
if (isset($_REQUEST['logout'])) {
  unset($_SESSION['access_token']);
}
if (isset($_GET['code'])) {
  $client->authenticate($_GET['code']);
  $_SESSION['access_token'] = $client->getAccessToken();
  $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
  header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
  $client->setAccessToken($_SESSION['access_token']);
} else {
  $authUrl = $client->createAuthUrl();
}
if ($client->getAccessToken()) {
  $_SESSION['access_token'] = $client->getAccessToken();
    $q = new 'Google_Service_Webmasters_SearchAnalyticsQueryRequest();
    $q->setStartDate('2015-09-01');
    $q->setEndDate('2015-09-01');
    $q->setDimensions(['page']);
    $q->setSearchType('web');
    try {
       $service = new Google_Service_Webmasters($client);
       $u = $service->searchanalytics->query('http://sschesnok.com.ua', $q);
       echo '<table border=1>';
       echo '<tr>
          <th>#</th><th>Clicks</th><th>CTR</th><th>Imp</th><th>Page</th><th>Avg. pos</th>';
          for ($i = 0; $i < count($u->rows); $i++) {
            echo "<tr><td>$i</td>";
            echo "<td>{$u->rows[$i]->clicks}</td>";
            echo "<td>{$u->rows[$i]->ctr}</td>";
            echo "<td>{$u->rows[$i]->impressions}</td>";
            echo "<td>{$u->rows[$i]->keys[0]}</td>";
            echo "<td>{$u->rows[$i]->position}</td>";
            /* foreach ($u->rows[$i] as $k => $value) {
                //this loop does not work (?)
            } */
            echo "</tr>";
          }             
        echo '</table>';
     } catch('Exception $e ) {
        echo $e->getMessage();
     }  
}
<div class="request">
<?php 
    if (isset($authUrl)) {
      echo "<a class='login' href='" . $authUrl . "'>Connect Me!</a>";
    } else {
      echo <<<END
