我在使用实际版本的 PHP api 示例以及使用示例文件夹的“service-account.php”文件时遇到问题。

原件用于显示“Books API”，并且使用我的个人凭据配置它运行良好，但在我的 xcase 中我需要通过 directory.groups.get 服务访问以获取 google 群组的成员帐户列表邮件列表，所以我更改了这里的原始代码:

<?php

session_start();
include_once "templates/base.php";

/************************************************
  Make an API request authenticated with a service
  account.
 ************************************************/
require_once realpath(dirname(__FILE__) . '/../autoload.php');

/************************************************
 ************************************************/

// MY ACCOUNT DATA HERE
$client_id = 'xxx';
$service_account_name = 'xxx'; //Email Address 
$key_file_location = 'xxx.p12'; //key.p12
$groupKey = 'xxx';

echo pageHeader("My Service Account Access");
if ($client_id == '<YOUR_CLIENT_ID>'
    || !strlen($service_account_name)
    || !strlen($key_file_location)) {
  echo missingServiceAccountDetailsWarning();
}

$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
//$service = new Google_Service_Books($client); //ORIGINAL
$service = new Google_Service_Directory($client);

/************************************************
 ************************************************/
if (isset($_SESSION['service_token'])) {
  $client->setAccessToken($_SESSION['service_token']);
}
$authArray = array(
                'https://www.googleapis.com/auth/admin.directory.group',
                'https://www.googleapis.com/auth/admin.directory.group.readonly',
                'https://www.googleapis.com/auth/admin.directory.group.member',
                'https://www.googleapis.com/auth/admin.directory.group.member.readonly'
);
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
    $service_account_name,
    $authArray, //array('https://www.googleapis.com/auth/books'), //ORIGINAL
    $key
);
$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();


/************************************************
 ************************************************/
//$optParams = array('filter' => 'free-ebooks'); //ORIGINAL
$optParams = array('fields' => 'id');
//$results = $service->volumes->listVolumes('Henry David Thoreau', $optParams); //ORIGINAL
$results = $service->groups->get($groupKey, $optParams);
echo "<h3>Results Of Call:</h3>";
foreach ($results as $item) {
  //echo $item['volumeInfo']['title'], "<br /> \n"; //ORIGINAL
    echo "<pre>".print_r ($item, true)."</pre>";
}

echo pageFooter(__FILE__);

无论我做什么，为 API SDK 提供授权，并使用刚刚在控制台开发人员的 API 凭据面板中创建的文件和凭据，我总是收到 403 错误。

这是错误堆栈:

#0 /var/www/html/google_local/google-api-php-client-master/src/Google/Http/REST.php(41): 
Google_Http_REST::decodeHttpResponse(Object(Google_Http_Request)) 
#1 /var/www/html/google_local/google-api-php-client-master/src/Google/Client.php(546):

#2 /var/www/html/google_local/google-api-php-client-master/src/Google/Service/Resource.php(190):

#4 /var/www/html/google_local/googl in /var/www/html/google_local/google-api-php-client-master/src/Google/Http/REST.php on line 76

有什么建议吗？

谢谢， 罗伯托

最佳答案

问题的根源在于服务帐户不是域中的管理员，因此它无法访问 Admin SDK Directory API。相反，您需要启用 domain-wide delegation为您的服务帐户，然后让服务帐户在发出请求时模拟域管理员:

$cred = new Google_Auth_AssertionCredentials(
    $service_account_name,
    $authArray,
    $key
);
$cred->sub = "admin@yourdomain.com";

关于php - Google_Service_Directory - (403) 无权访问此资源/api，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26409201/
