Azure EventGrid 触发器 - Webhooks

Question

我正在尝试使用 webhook 端点创建一个 azure 事件网格函数。但是当我尝试创建事件网格订阅时，它显示:

"Deploying Event Subscription: event-store-in-delta Deployment hasfailed with the following error: {"code":"Urlvalidation","message":"Webhook validation handshake failed forhttps://1e8f90c31be0.ngrok.io/runtime/webhooks/EventGrid. Http POSTrequest failed with response code Unknown. For troublehooting, visithttps://aka.ms/esvalidation. Activityid:1d113deb-63d2-467a-b21d-36e289fa5b99, timestamp: 6/10/2021 1:01:46PM (UTC)."}

有人遇到过这个错误吗？

HTTP 触发器函数需要实现一些验证逻辑才能充当事件网格端点。 Azure 文档提供了有关该问题的多个页面。

• Endpoint validation with Event Grid events

  If you're using any other type of endpoint, such as an HTTP triggerbased Azure function, your endpoint code needs to participate in avalidation handshake with Event Grid. Event Grid supports two ways ofvalidating the subscription.

• Receive events to an HTTP endpoint

此外，您需要确保事件网格可以访问您的端点。通常，功能键需要作为 webhook URL 中的查询参数 code 提供。
