    text
    copied!<p>I use SignalR 1.0.1 as a chat core for ASP.NET MVC3 application. Using IIS 7.5<br/><br/> There are two methods in MVC controller which provides access to chat views:<br/> 1. First method is public, allowing anonymous users to chat - no authorization.<br/> 2. Access to second method is restricted with <code>[Authorize]</code> attribute, for domain users - chat agents.<br/><br/> There is no explicitly specified authorization in the Hub.<br/> For this scenario I involved both Windows and Anonymous authentication on IIS.<br/><br/> I also implemented custom Role Provider, which operates only in memory - not persisting anything to database. </p> <p>What happens is that using '[Authorize]' attribute in controller method leads to responsing 500 from Hub, both when call is coming from authorized view, and the anonymous one:</p> <p>Request (<code>send</code> is Hub method for sending messages):<br/><br/> <code>http://localhost:8101/signalr/send?transport=serverSentEvents&amp;connectionToken=VIXEZzWQSn5SNlA8RUy4iaOPDFdvuPBjMvFBiG2FLfvfxF347XHwtapsEV5ndU4OEI0Xb64W2ZRXTqwBiL2CXg2_JlTaTJ2RnVOj4bjvx6tQaYhAqTaXs9k2853GYqzd0</code></p> <p>Response:<br/><br/> <code>The connection id is in the incorrect format.</code></p> <pre><code>Server stack trace: at Microsoft.AspNet.SignalR.PersistentConnection.GetConnectionId(HostContext context, String connectionToken) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.Owin.CallHandler.Invoke(IDictionary2 environment) at Microsoft.AspNet.SignalR.Owin.Handlers.HubDispatcherHandler.Invoke(IDictionary2 environment) at Microsoft.Owin.Host.SystemWeb.OwinCallContext.Execute() at Microsoft.Owin.Host.SystemWeb.OwinHttpHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object extraData)&lt;br/&gt;&lt;br/&gt; </code></pre> <p>But notice, that connecting to Hub works fine, returns 200 OK:<br/> <code>http://localhost:8101/signalr/connect?transport=serverSentEvents&amp;connectionToken=dYOwFxa1mkgdpzw-jitRpWq9oxRlrTet8U_dAzWjFQEdGNJfVXeG7Op0NZZwvznxeNdJCuPT75CKzQqI9HRPThV3uEDt-Z2qtIl9E02gF481&amp;connectionData=%5B%7B%22name%22%3A%22chathub%22%7D%5D&amp;tid=9</code><br/></p> <p>I found little similiar thread here on stackoverflow:<br/> <a href="https://stackoverflow.com/questions/15349043/signalr-the-connection-id-is-in-the-incorrect-format">signalr The connection id is in the incorrect format</a></p> <p><br/> from which I understand, that when invoking my <code>Send</code> method, the Hub is processing request with <code>Identity</code> different than the one used to connect to Hub, OR Hub's <code>GetConnectionId</code> finds, that user is actually not authorized - but how it checks that assumption, when there is no authorization specified on the Hub itself? <br/><br/></p> <p>Can someone put some light on this?</p> <p>Thanks in advance :)</p>
