谷歌分析如何提供访问令牌

Question

我正在尝试从谷歌分析 API 获取实时用户

我正在关注这个：https://developers.google.com/analytics/devguides/reporting/core/v4/basics

我发布的数据如下：

$url = 'https://analyticsreporting.googleapis.com/v4/reports:batchGet';

//Initiate cURL.
$ch = curl_init($url);

$jsonDataEncoded = '{
  "reportRequests":
  [
    {
      "viewId": "109200098",
      "dateRanges": [{"startDate": "2014-11-01", "endDate": "2014-11-30"}],
      "metrics": [{"expression": "ga:users"}]
    }
  ]
}'
;

//Tell cURL that we want to send a POST request.
curl_setopt($ch, CURLOPT_POST, 1);

//Attach our encoded JSON string to the POST fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);

//Set the content type to application/json
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); 

//Execute the request
$result = curl_exec($ch);

print_r($result);

{ "error": { "code": 401, "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.", "status": "UNAUTHENTICATED" } }

我知道我应该为此获得一些 OAuth，但我不知道如何做到这一点。 你能帮我解决这个问题吗？ 谢谢！

index.php 和 oauth2callback.php

和这里一样：https://developers.google.com/analytics/devguides/reporting/core/v4/quickstart/web-php

现在我想使用 https://developers.google.com/analytics/devguides/reporting/realtime/v3/reference/data/realtime/get#auth 来获取 rt:activeUsers

我正在编辑 index.php ：

    if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
      // Set the access token on the client.
      $client->setAccessToken($_SESSION['access_token']);

      // Create an authorized analytics service object.
      $analytics = new Google_Service_AnalyticsReporting($client);

      // Call the Analytics Reporting API V4.
      $response = getReport($analytics);

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

try {
  $results = $analytics->data_realtime->get(
      'ga:56789',
      'rt:activeUsers',
      $optParams);
  // Success. 
} catch (apiServiceException $e) {
  // Handle API service exceptions.
  $error = $e->getMessage();
}

      // Print the response.
      printResults($response);

    } else {
      $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php';
      header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
    }

出现错误：未定义属性：Google_Service_AnalyticsReporting::$data_realtime

Answer 1

我可以使用更新的 index.php 来做到这一点

<?php

// Load the Google API PHP Client Library.
require_once __DIR__ . '/vendor/autoload.php';

session_start();

$client = new Google_Client();
$client->setAuthConfig(__DIR__ . '/client_secret.json');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);
$service = new Google_Service_Analytics($client);

// If the user has already authorized this app then get an access token
// else redirect to ask the user to authorize access to Google Analytics.
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
  // Set the access token on the client.
  $client->setAccessToken($_SESSION['access_token']);

  // Create an authorized analytics service object.
  $analytics = new Google_Service_AnalyticsReporting($client);

  // Call the Analytics Reporting API V4.
  $response = getReport($analytics);

  // Print the response.
  printResults($response);



    $result = $service->data_realtime->get(
        'ga:<VIEWID CHANGE>',
        'rt:activeVisitors'
    );
    echo "<pre>";
    print_r($result->totalsForAllResults['rt:activeVisitors']);
    echo "</pre>";

} else {
  $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php';
  header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}


/**
 * Queries the Analytics Reporting API V4.
 *
 * @param service An authorized Analytics Reporting API V4 service object.
 * @return The Analytics Reporting API V4 response.
 */
function getReport($analytics) {

  // Replace with your view ID, for example XXXX.
  $VIEW_ID = "<VIEW ID>";

  // Create the DateRange object.
  $dateRange = new Google_Service_AnalyticsReporting_DateRange();
  $dateRange->setStartDate("7daysAgo");
  $dateRange->setEndDate("today");

  // Create the Metrics object.
  $sessions = new Google_Service_AnalyticsReporting_Metric();
  $sessions->setExpression("ga:sessions");
  $sessions->setAlias("sessions");

  // Create the ReportRequest object.
  $request = new Google_Service_AnalyticsReporting_ReportRequest();
  $request->setViewId($VIEW_ID);
  $request->setDateRanges($dateRange);
  $request->setMetrics(array($sessions));

  $body = new Google_Service_AnalyticsReporting_GetReportsRequest();
  $body->setReportRequests( array( $request) );
  return $analytics->reports->batchGet( $body );
}


/**
 * Parses and prints the Analytics Reporting API V4 response.
 *
 * @param An Analytics Reporting API V4 response.
 */
function printResults($reports) {
  for ( $reportIndex = 0; $reportIndex < count( $reports ); $reportIndex++ ) {
    $report = $reports[ $reportIndex ];
    $header = $report->getColumnHeader();
    $dimensionHeaders = $header->getDimensions();
    $metricHeaders = $header->getMetricHeader()->getMetricHeaderEntries();
    $rows = $report->getData()->getRows();

    for ( $rowIndex = 0; $rowIndex < count($rows); $rowIndex++) {
      $row = $rows[ $rowIndex ];
      $dimensions = $row->getDimensions();
      $metrics = $row->getMetrics();
      for ($i = 0; $i < count($dimensionHeaders) && $i < count($dimensions); $i++) {
        print($dimensionHeaders[$i] . ": " . $dimensions[$i] . "\n");
      }

      for ($j = 0; $j < count($metrics); $j++) {
        $values = $metrics[$j]->getValues();
        for ($k = 0; $k < count($values); $k++) {
          $entry = $metricHeaders[$k];
          print($entry->getName() . ": " . $values[$k] . "\n");
        }
      }
    }
  }
}

首先，如果您想访问实时数据，那么您使用了错误的 api。你应该使用realtime api

使用 curl 进行身份验证有点复杂。您需要先获取刷新令牌。获得后，您可以在需要时使用以下内容获取访问令牌。

curl \ –request POST \ –data ‘client_id=[Application Client Id]&client_secret=[Application Client Secret]&refresh_token=[Refresh token granted by second step]&grant_type=refresh_token’ \ https://accounts.google.com/o/oauth2/token

您需要做的就是将 &access_token=token 添加到您对 api 发出的任何请求中。

我的完整教程可以在这里找到Google auth curl

更新：

请记住，实时 API 与报告 API 不同。如果您仍在引用报告 api，那么它就无法工作。您现在应该发送 HTTP GET 而不是 HTTP Post，并且终点是

https://www.googleapis.com/analytics/v3/data/realtime  

查看文档realtime.get 调用的格式也不同

按照这些思路应该不会很难

https://www.googleapis.com/analytics/v3/data/realtime?id=XXX&metrics=XXX&accesstoken=XXX  

正如我所说，它是一个 HTTP GET，因此您可以在将其添加到 Curl 脚本之前将其转储到浏览器中进行测试。
