管理SDK，目录API，用户:列表-任何PHP示例如何做到这一点？

Question

；注册的应用程序-&>；名称}-&>；Web应用程序-&>；OAuth 2.0客户端/LI> ；管理API(On)/li> ；安全性-&>；API访问（已检查）/LI>
1. “-&>”-&>；第三方OAuth-&>；API客户端（ClientID.apps.googleusercontent.com)/li>
2. “-&>”-&>；“-&>API作用域（https://www.googleapis.com/auth/admin.directory.user)/li>

这是我目前所掌握的，

require_once 'google/appengine/api/app_identity/AppIdentityService.php';
use \google\appengine\api\app_identity\AppIdentityService;

function setAuthHeader() {
  $access_token =AppIdentityService::getAccessToken("https://www.googleapis.com/auth/admin.directory.user");
  return [ sprintf("Authorization: OAuth %s", $access_token["access_token"]) ];
}

$get_contacts_url = "https://www.googleapis.com/admin/directory/v1/users?customer=my_customer";
$headers = implode("\n\r", setAuthHeader());
$opts =
  array("http" =>
  ["http" => ["header" => $headers ]]
);
$context = stream_context_create( $opts );
$response = file_get_contents( $get_contacts_url, false, $context );
print_r ($response);

“access_token”通过得很好，但是响应返回，

{ "error": { "errors": [ { "domain": "global", "reason": "required", "message": "Login Required", "locationType": "header", "location": "Authorization" } ], "code": 401, "message": "Login Required" } }

null

GET https://www.googleapis.com/admin/directory/v1/users?customer=my_customer&key={YOUR_API_KEY}

YOUR_API_KEY}是什么？我试过所有的云控制台和谷歌应用程序API，但都没有运气。

我做这件事完全错了，我应该用一种完全不同的方法吗？我已经为这个问题挣扎了一个多星期了，我希望得到任何形式的回应。谢谢

Answer 1

您使用的是最新的PHP库还是不推荐使用的？对于最新的测试版PHP库，这是与身份验证部分相关的代码部分。

set_include_path("google-api-php-client-master/src/" . PATH_SEPARATOR . get_include_path());
require_once 'Google/Client.php';
require_once 'Google/Auth/OAuth2.php';

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

$key = file_get_contents($key_file_location);

$cred = new Google_Auth_AssertionCredentials(
  // Replace this with the email address from the client.
  $clientEmail,
  // Replace this with the scopes you are requesting.
  array(SCOPES),
  $key
);
$cred->sub = ""; //admin email
$client->setAssertionCredentials($cred);

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

$_SESSION['service_token'] = $client->getAccessToken();

Answer 2

简而言之:您过于简化了OAuth2。

它不像发送一个HTTP GET参数那样容易获取数据。

我相信您已经阅读了这篇文章，但是您需要理解OAuth2 web流，以及客户机库如何为您利用它。您应该需要这个文件才能使用目录API。

我认为最简单的方法是使用PHP客户端库https://github.com/Google/google-api-php-client/，它可以很好地处理身份验证。如果你尝试自己做，JWT的东西会变得非常棘手。我刚刚为您提供了一个这样做的示例，https://gist.github.com/fillup/9fbf5ff35b337b27762a。我用我自己的谷歌应用程序帐号测试了它，并验证了它的工作，如果你有问题，请告诉我。

编辑:在此处添加代码示例以方便使用:

print_r($list);
