问题
I'm using the following code to set up a StreamSocketListener on my universal 8.1 app:
_listener = new StreamSocketListener();
_listener.Control.QualityOfService = SocketQualityOfService.Normal;
_listener.ConnectionReceived += OnConnectionReceived;
await _listener.BindServiceNameAsync("8776");
This runs without any problems, however when I try & browse to http://localhost:8776 (or directly via ip address or machine name), the request times out.
In netstat I can see the 8776 port is open & listening, I've enabled loopback exemption, disabled my firewall, but I'm still not able to connect. This is true for both the Windows 8.1 and the Windows Phone 8.1 app.
When I try to connect from another machine, it works without problems. Is there any setting/configuration I can use so I'm able to connect from the same machine?
回答1:
Windows RT blocks loopback access between two WinRT applications.
Network communications using an IP loopback address cannot be used for interprocess communication (between two different apps) in a Windows Runtime app since this is restricted by network isolation. Network communication using an IP loopback address is allowed within an app within the same process for communication purposes.
