Azure 事件网格主题的应用程序网关后端池

Question

I would like to ask if it is possible to use Azure Application Gateway to route(backend pool) traffic to Azure Event Grid Topic. I have tested it but no matter what i do i always get 502 error when i tries to perform a POST Request to my App Gateway.

Here is the sample flow:

[user] ===> [Application Gateway]====>[EventGrid Topic]====> Azure Function

Is this possible?

I got working, make sure you have the application setup as follows:

There is not a 'healthcheck' endpoint from Event Grid hence I just added the FQDN + /ping to the healthprobe and configured the probe to accept a 404.

In the HTTP settings you should make sure that the incoming hostname gets overrided with the EG FQDN by using the "Override with new hostname" option. After that it should work just fine.Take a look at the rest of my HTTP settings below.
