使用IE11时，ASP.NET WebForms中的Login ReturnUrl导致JavaScript严重错误

Question

I am developing ASP.NET Web Forms application using Visual Studio 2012, which utilizes bundling and SignalR.

I put this in my web.config:

<authentication mode="Forms">
  <forms loginUrl="~/Account/Login" defaultUrl="~/Views/Portfolio" timeout="2880" />
</authentication>
<authorization>
  <deny users ="?" />
  <allow users = "*" />
</authorization>

When I hit F5 I get this kind of error:

JavaScript critical error at line 3, column 1 in http://localhost:6169/Account/Login?ReturnUrl=/bundles/WebFormsJs?v=AAyiAYwMfvmwjNSBfIMrBAqfU5exDukMVhrRuZ-PDU01&v=AAyiAYwMfvmwjNSBfIMrBAqfU5exDukMVhrRuZ-PDU01

SCRIPT1002: Syntax error

then followed by this:

JavaScript critical error at line 3, column 1 in http://localhost:6169/Account/Login?ReturnUrl=/signalr/hubs

SCRIPT1002: Syntax error

I am using IE11 and these kind of errors didn't happen when using Firefox or Chrome. Please help? Thanks

Answer 1

Typically you cannot bundle dynamically generated JavaScript such as /signalr/hubs.

If you want to bundle the /signalr/hubs script (aka the SignalR JS hub proxy), you need to generate the script before deployment . This will give you a static JS file that you can bundle.

Answer 2

The solution put forward by Halter73 worked for me, initially. I was getting similar errors in IE11 and specifically noticed the "ReturnUrl=/signalr/hubs" in the URL. However, I found some regression issues with the static proxy (both a chat and a users online widget broke) and so I rolled it back to using the default dynamically generated proxy.

So after doing that, I was back to the same error and I returned here and re-read the OP's original post and his own reply very carefully and realized it might be an issue with the authorization settings in my web.config, of which there were none for signalr/hubs. Like the OP I also deny auth from various areas of my site so I needed to explicitly allow access to signalr/hubs so I simply added this to fix my issue:

  <location path="signalr/hubs">
    <system.web>
        <authorization>
            <allow users="*"/>
        </authorization>
    </system.web>
  </location>
