如何在 php 中获取谷歌分析实时 activeUsers？

Question

我从 https://github.com/google/google-api-php-client 并尝试了下面的代码...

$client->setApplicationName("Analytics");
$client->setDeveloperKey("key");
$service = new Google_Service_Analytics($client);

$optParams = array(
    'dimensions' => 'rt:medium');

try {
  $results = $service->data_realtime->get(
      'ga:profileid',
      'rt:activeUsers',
      $optParams);
  // Success.
} catch (apiServiceException $e) {
  // Handle API service exceptions.
  $error = $e->getMessage();
}
print_r($results);

显示错误（401）需要登录'

当我尝试来自https://console.developers.google.com/project/apps~rational-photon-578/apiui/api/analytics/method/analytics.data.realtime.get的电话时

我获得了所需的实时用户所属的 profileid。

那么我该如何实现登录过程（无需访问谷歌网站）？

我试过下面的代码...

$client_id              = 'xxxxxxxxxxxxxxx';
$service_account_name   = 'xxxxxxxxxxxxxxxx@developer.gserviceaccount.com';
$key_file_location      = 'location of .p12 keyfile';

$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");

if (isset($_SESSION['service_token'])) {
$client->setAccessToken($_SESSION['service_token']);
}

$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
$service_account_name,
array('https://www.googleapis.com/auth/analytics'),
$key
);

$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {
$client->getAuth()->refreshTokenWithAssertion($cred);
} 

$_SESSION['service_token'] = $client->getAccessToken();
echo $_SESSION['service_token'];
$service = new Google_Service_Analytics($client);


$optParams = array(
'dimensions' => 'rt:medium');


try {
$results = $service->data_realtime->get(
  'ga:profileid',
  'rt:activeUsers',
  $optParams);
// Success.
} catch (apiServiceException $e) {
// Handle API service exceptions.
$error = $e->getMessage();
}
print_r($results);

我在这里获取 access_token 和详细信息...但分析数据获取失败，因为错误“权限不足”

当我使用提到的配置文件 ID 从谷歌控制台进行测试时，我得到了结果。

Answer 1

访问 Google Analytics API 需要身份验证。听起来您想访问自己的数据，而不是其他用户拥有的数据。为此，您需要创建一个service account.

您正在使用的 Github 上的 php 客户端库，有一个使用服务帐户的示例，您可以找到它service-account.php

该示例使用 Books API。您可以通过执行以下操作将其更改为 Google 分析 API

$service = new Google_Service_Books($client);

改成

$service = new Google_Service_Analytics($client);

如果您有任何问题，请告诉我，我会看看能否给您一个完整的示例，使用 Google Analytics（分析）和服务帐户。

给其他人的注意事项：

在提出这个问题时，实时 API 仍处于测试阶段，您必须请求访问。通常需要 24 小时才能访问。

我已使用以下 php 代码成功地将我的 GA 帐户中的当前数据显示到我的网站：

<?php

//Cloning Google API's
//git clone https://github.com/google/google-api-php-client.git

//Setting include_path in PHP.ini
//include_path = ".:/usr/local's/lib/php:/path/to/google-api-php-client/src"

//Alternatively, you can set the same ini directive dynamically in your code.
$lib_path = $_SERVER['DOCUMENT_ROOT'] . '/path/relative/to/DOCUMENT_ROOT/';
set_include_path(get_include_path() . PATH_SEPARATOR . $lib_path . 'google-api-php-client/src');

require_once 'Google/Client.php';
require_once 'Google/Service/Analytics.php';

$keyfile = 'path/relative/to/DOCUMENT_ROOT/xxxxxxxxxxxxxxxx.p12'; // keyfile location   
$gaEmail = 'xxxxxxxxxxxxxxxx@developer.gserviceaccount.com'; // email you added to GA
$gaAuth = 'https://www.googleapis.com/auth/analytics.readonly';

// Create Client Object
$client = new Google_Client();
$client->setApplicationName('Google_Analytics'); // name of your app
$client->setClientId('xxxxxxxxxxxxxxxx.apps.googleusercontent.com'); // from API console
$client->setAssertionCredentials(new Google_Auth_AssertionCredentials($gaEmail, array($gaAuth), file_get_contents($keyfile)));

/* Sample Grabbing Analytics data
$service = new Google_Service_Analytics($client);
var_dump($service->management_accounts->listManagementAccounts());
$response = $service->data_ga->get(
    'ga:87364223', // profile id
    '2014-09-01', // start date
    '2014-09-10', // end date
    'ga:uniquePageviews',
    array(
        'dimensions' => 'ga:pagePath',
        'sort' => '-ga:uniquePageviews',
        'filters' => 'ga:pagePath=~/[a-zA-Z0-9-]+/[a-zA-Z0-9-]+', // http://localhost/browse/style/3#showmoreexample url regex filter
        'max-results' => '25'
    )
);
var_dump($response);
*/

// Your analytics profile id. (Admin -> Profile Settings -> Profile ID)
$profile_id = 'ga:xxxxxxxx';
$start = 'yesterday';
$end = 'today';

try {
    $service = new Google_Service_Analytics($client);
    $results = $service->data_ga->get($profile_id, $start, $end, 'ga:visits');
    echo $results['totalsForAllResults']['ga:visits'];
} 
catch(Exception $e) {
    echo 'There was an error : - ' . $e->getMessage();
}
