C# Nancy.Hosting.Self 不响应来自网络的请求，只响应本地主机请求

Question

I am trying to integrate nancy self hosting into my wpf project and when I start my program, I am able to connect to rest api from local browser, but cannot connect from another computer.

HostConfiguration hostConfigs = new HostConfiguration();
hostConfigs.UrlReservations.CreateAutomatically = true;

NancyHost host = new NancyHost(hostConfigs, new Uri("http://localhost:1234"));
host.Start();

Is there a way I can set Uri to wildcard, like in other built in web servers, 0.0.0.0 or + ?

EDIT Windows firewall is disabled!! I've also tried with different configurations of host, with http://10.10.10.149:1234 " as a host. I've tryed " http://+:1234 , this one doesn't build, it throws error.

I've also completely removed hostConfigs and added ACL to the system by running some commands in powershell, like suggested in many articles:

netsh http add urlacl url="http://+:12345/" user="Everyone"

Still, can only connect from local browser, not from another network location. Whenever I try to connect to machine where program is running via rest api, I get 503 Service Unavailable.

Answer 1

您需要将其更改为"http://+:1234"以绑定到所有网络接口。

Answer 2

SOLUTION

Although my firewall is disabled completely, it was the firewall that was causing problems. I found solution in this article: C# HttpListener and Windows Firewall

All I needed to do, was adding the rule for system program to firewall. If anyone comes to this problem, this solution worked for me. I can now access api from another LAN too, so I guess it would work from any remote IP.

Answer 3

I have faced with a similar problem. I searched a lot of discussions and I had no answer. Then I found previous messages. I worked for me.

It was a firewall issue. And the solution;

1- Go to firewall settings 2- Inbound firewall rules 3- Add a new rule 4- Connection point (TCP / UDP) 5- TCP 6- (Enter port numbers) 7- Allow connection

I have shared my experience in case anyone need it.
