Microsoft Graph Rest API："notification endpoint validation" 是如何工作的？

Question

阅读文档我看到... "The client must provide a response with the following characteristics within 10 seconds:"

一个 200（正常）状态代码。
内容类型必须是text/plain。
正文必须包含 Microsoft Graph 提供的验证令牌。

我在客户端收到的请求是

/?validationToken=Validation%3a+Testing+client+application+reachability+for+subscription+Request-Id%3a+ef492401-75ec-4ac8-b87a-89d0b81ae977

所以我给的回复是

$responseCode = 200;
http_response_code($responseCode);
header('Content-type: text/plain');
echo $response = $_GET['validationToken'];

翻译后，..是：

Validation: Testing client application reachability for subscription Request-Id: ef492401-75ec-4ac8-b87a-89d0b81ae977

为什么我会收到此回复？

< HTTP/1.1 400
< {
<     "error": {
<         "code": "InvalidRequest",
<         "message": "Subscription validation request failed. Must respond with 200 OK to this request.",
<         "innerError": {
<             "request-id": "ef492401-75ec-4ac8-b87a-89d0b81ae977",
<             "date": "2020-02-04T14:50:35"
<         }
<     }
< }

Answer 1

问题出在这里：

$request["notificationUrl"] = $conf['NotificationURL'];
$request["lifecycleNotificationUrl"] = "https://webhook.azurewebsites.net/api/lifecycleNotifications";

配置中的第二个 URL 不存在。如果调用，return 400。正确的配置应该是：

$request["notificationUrl"] = $conf['NotificationURL'];
$request["lifecycleNotificationUrl"] = $conf['NotificationURL'];

那就解决问题了。
