Azure：应用服务中的 C# HttpListener 访问被拒绝错误

Question

I am developing an aspnet webapp which is currently deployed on latest IIS and working fine. Now My client asked me to move same application over azure App Service.

I deploy it there and Http Listener which is included in application has stopped working. Same code is working on server machine.

HttpListener listener = new HttpListener(); listener.Prefixes.Add('https//customerurlnameazurewebsites.net/'); listener.Start();

Error is on listener.Start() I am recieving bad gateway error on postman

502 - Web server received an invalid response while acting as a gateway or proxy server.

After Azure Remote Debugging I have found Exception 'Access denied' on

listener.Start();

Same Exception was concurring on local machine and server machine I had solve that problem by following command.

netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

Answer 1

What is the listening on url ?

If it listen localhost port. In Azure App Services, it just support 80 and 443 . If other server URL,it should be works fine.

You also can refer to the comment in this post. I think the usage of HttpListener is correct, it should be useful to you.
