Question

Microsoft Webhook订阅正在发送奇怪的正文数据，并且validationToken参数中没有文本。 Microsoft Graph团队中有人可以提供帮助吗？

这就是我要发送的内容（出于隐私目的，我更改了notificationUrl中的实际域名）。

{
    "changeType": "created",
    "notificationUrl": "https://myapp.com/version-test/api/1.1/wf/msgraphvalidation",
    "resource": "me/mailFolders/inbox/messages",
    "expirationDateTime": "2018-08-27T18:23:45.9356913Z"
 }

这是使用上述信息将POST发送到“ https://graph.microsoft.com/v1.0/subscriptions”或“ https://graph.microsoft.com/beta/subscriptions”后在正文中返回的内容。

Request data
{
    "bold": "\u001b[1m\u001b[22m",
    "underline": "\u001b[4m\u001b[24m",
    "strikethrough": "\u001b[9m\u001b[29m",
    "italic": "\u001b[3m\u001b[23m",
    "inverse": "\u001b[7m\u001b[27m",
    "grey": "\u001b[90m\u001b[39m",
    "black": "\u001b[30m\u001b[39m",
    "yellow": "\u001b[33m\u001b[39m",
    "red": "\u001b[31m\u001b[39m",
    "green": "\u001b[32m\u001b[39m",
    "blue": "\u001b[34m\u001b[39m",
    "white": "\u001b[37m\u001b[39m",
    "cyan": "\u001b[36m\u001b[39m",
    "magenta": "\u001b[35m\u001b[39m",
    "greyBG": "\u001b[49;5;8m\u001b[49m",
    "blackBG": "\u001b[40m\u001b[49m",
    "yellowBG": "\u001b[43m\u001b[49m",
    "redBG": "\u001b[41m\u001b[49m",
    "greenBG": "\u001b[42m\u001b[49m",
    "blueBG": "\u001b[44m\u001b[49m",
    "whiteBG": "\u001b[47m\u001b[49m",
    "cyanBG": "\u001b[46m\u001b[49m",
    "magentaBG": "\u001b[45m\u001b[49m",
    "rainbow": "",
    "zebra": "",
    "stripColors": "",
    "zalgo": ""
}

这是完整的错误：

{ 
"error": { 
    "code": "InvalidRequest", 
    "message": "Subscription validation request failed. Response must exactly match validationToken query parameter.",
    "innerError": { 
        "request-id": "08008b1b-4eda-4a09-a0d5-45ffcce1a8d6", 
        "date": "2018-08-26T02:43:08" 
    }
}
}

Answer 1

Microsoft Graph在创建订阅之前验证订阅请求的notificationUrl属性中提供的通知端点。请参阅以下链接

https://developer.microsoft.com/en-us/graph/docs/concepts/webhooks

Microsoft Graph WebHook: Subscription validationtoken blank?

您可以像这样验证通知网址

if (Request.QueryString["validationToken"] != null)
            {
                var token = Request.QueryString["validationToken"];
                return Content(token, "plain/text");
            }

https://github.com/microsoftgraph/aspnet-webhooks-rest-sample/blob/master/GraphWebhooks/Controllers/NotificationController.cs

Answer 2

validationToken在查询字符串上，而不在请求的正文中。

Answer 3

您的通知端点似乎没有响应查询字符串中的验证令牌。响应应该只是纯文本形式的验证令牌。

不确定是否故意这样做，但是您发送的请求的通知URL与您在本文中提到的通知URL不匹配。

Answer 4

Microsoft Graph API询问了notificationUrl。调用订阅API时显示的是JSON

//POST https://graph.microsoft.com/v1.0/subscriptions    

{
           "changeType": "created,updated,deleted",
           "notificationUrl": "https://your_domain/outlook/ms_ping",
           "resource": "me/messages",
           "expirationDateTime":"2020-07-08T18:23:45.9356913Z",
           "clientState": "secretClientValue",
           "latestSupportedTlsVersion": "v1_2"
 }

一旦您调用Microsoft Subscription API，API就会在您的validationToken中向您发送notificationUrl。您只需使用您在API正文中发送的 200个响应代码从validationToken对此notificationUrl进行响应。这是代码

//https://your_domain/outlook/ms_ping.php
    <?php
        $token = $_REQUEST['validationToken'];
        header("content-type:application/json");
        http_response_code(200);
        echo ($token);
    ?>

订阅验证请求失败。响应必须与validationToken查询参数完全匹配
