篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了3600秒后获取新的访问令牌相关的知识，希望对你有一定的参考价值。

我正在尝试使用谷歌分析API。我已将已创建的服务帐户电子邮件添加到相关Google Analytics帐户的用户列表中。

我得到了access_token和refresh_token。但是我不知道如何在没有客户端重新授权的情况下在3600秒后获得新的access_token。

oauth2callback.php

<?php
require_once __DIR__.'/vendor/autoload.php';

session_start();

$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');

if (! isset($_GET['code'])) {
  $auth_url = $client->createAuthUrl();
  header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
  $client->authenticate($_GET['code']);
  $_SESSION['access_token'] = $client->getAccessToken();
  $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/';
  header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

的index.php

<?php
require_once __DIR__.'/vendor/autoload.php';

session_start();

$client = new Google_Client();
$client->setAuthConfig('client_secrets.json');
$client->setAccessType("offline");
$client->setIncludeGrantedScopes(true);
$client->setApprovalPrompt('force');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');

if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
  $client->setAccessToken($_SESSION['access_token']);

print_r($_SESSION['access_token']);

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

允许访问后，令牌正常生成。但我希望在3600秒后自动获取新的access_token，而客户端不必再次授予权限。

这可能吗？

print_r($_SESSION['access_token']);

答案

您使用的代码不是服务帐户的代码。如果您将代码用于服务帐户，则无需担心刷新任何东西，因为它没有刷新令牌，它始终具有访问权限。

require_once __DIR__ . '/vendor/autoload.php';
// Use the developers console and download your service account
// credentials in JSON format. Place the file in this directory or
// change the key file location if necessary.
putenv('GOOGLE_APPLICATION_CREDENTIALS='.__DIR__.'/service-account.json');
/**
 * Gets the Google client refreshing auth if needed.
 * Documentation: https://developers.google.com/identity/protocols/OAuth2ServiceAccount
 * Initializes a client object.
 * @return A google client object.
 */
function getGoogleClient() {
    return getServiceAccountClient();
}
/**
 * Builds the Google client object.
 * Documentation: https://developers.google.com/api-client-library/php/auth/service-accounts
 * Scopes will need to be changed depending upon the API's being accessed. 
 * array(Google_Service_Analytics::ANALYTICS_READONLY, Google_Service_Analytics::ANALYTICS)
 * List of Google Scopes: https://developers.google.com/identity/protocols/googlescopes
 * @return A google client object.
 */
function getServiceAccountClient() {
    try {   
        // Create and configure a new client object.        
        $client = new Google_Client();
        $client->useApplicationDefaultCredentials();
        $client->addScope([YOUR SCOPES HERE]);
        return $client;
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}

ServiceAccount.php

另一答案

挑出来：

<?php
require_once __DIR__ . '/vendor/autoload.php';
$KEY_FILE_LOCATION = __DIR__ . '/service-account.json';
$client = new Google_Client();
$client->setAuthConfig($KEY_FILE_LOCATION);
$client->setAccessType('offline');
$client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
$client->refreshTokenWithAssertion();
$analytics = new Google_Service_Analytics($client);
$token = $client->getAccessToken();
