问题
I am trying to create a chat application using signalR using VS2012 web in a website. But its showing me error like this:
Failed to load resource: the server responded with a status of 404 (Not Found)
http://localhost:50780/WebApplication1/WebApplication1/signalr/hubs
Uncaught TypeError: Cannot read property 'client' of undefined
I have added RouteTable.Routes.MapHubs(); to Global.asax
But why should its showing me this error when its opening for other's system.
回答1:
On the page where you're including signalr/hubs:
Change your script tag to look like this:
<script src="~/signalr/hubs"></script>
@drch's answer is also correct (if you're making that mistake) but the more common issue I see is people just doing "signalr/hubs" in their script tag and then the hubs url is then incorrect (in some circumstances).
Ultimately the hubs url resides off of the SignalR endpoint so doing a "~/signalr/hubs" makes the path app relative which should ensure that it retrieves the hubs.js from the correct url.

I know, that I'm late, but for smbd who will finding answers: I've resolved the problem by registrate .Net frame work to IIS. Do next steps into console (Win+R):
cd %windir%\Microsoft.NET\Framework\v4.0.30319
aspnet_regiis.exe –i
