SignalR Cimpilation Error #5115

pankajmathur created 6 years ago

Hi,

I have downloaded the Module Zero (5.4) having ABP (3.6.1) with MVC and JQuery Template project for .Net Core 2.0. I am following the document <a class="postlink" href="https://aspnetboilerplate.com/Pages/Documents/SignalR-AspNetCore-Integration">https://aspnetboilerplate.com/Pages/Doc ... ntegration</a> for implementing SignalR.

I installed the Nuget packet Abp.AspNetCore.SignalR in the .Web.Core Project. Then in the .Web.Mvc project, startup.cs file I wrote the first line as #define FEATURE_SIGNALR

Now the below line (after using statements )(these lines were already there in the project) throwing errors... #if FEATURE_SIGNALR using Owin; using Abp.Owin; using Microsoft.AspNet.SignalR; using Microsoft.AspNet.SignalR.Hubs; using Abp.AspNetZeroCore.Web.Owin; using Owin.Security.AesDataProtectorProvider; #endif

Also following line in Configure method of Startup.cs is not compiling. #if FEATURE_SIGNALR //Integrate to OWIN app.UseAppBuilder(ConfigureOwinServices); #endif

Also following line of code is not compiling....

#if FEATURE_SIGNALR private static void ConfigureOwinServices(IAppBuilder app) { GlobalHost.DependencyResolver.Register(typeof(IAssemblyLocator), () => new SignalRAssemblyLocator()); app.Properties["host.AppName"] = "iVend365";

        app.UseAbp();
        app.UseAesDataProtectorProvider();

        app.MapSignalR();
    }

#endif

Please help me what should I fix to proceed and complete the SignalR implementation.....

Regards, Mahendra

Those lines are for old SignalR, so don't enable them.

Thanks...I did that...Now following the document <a class="postlink" href="https://aspnetboilerplate.com/Pages/Documents/SignalR-AspNetCore-Integration">https://aspnetboilerplate.com/Pages/Doc ... ntegration</a> at the following step..."Client-Side (jQuery)", I included below lines in my Area/Mpa/Views/Layout/_Layout.cshtml file....

<script src="~/lib/signalr-client/signalr.min.js"></script> <script src="~/lib/abp-web-resources/Abp/Framework/scripts/libs/abp.signalr-client.js"></script>

Now when I run any of my pages, it throws me following error:

abp.signalr-client.js:97 Uncaught TypeError: Cannot read property 'WebSockets' of undefined at startConnection (abp.signalr-client.js:97) at Object.abp.signalr.connect (abp.signalr-client.js:47) at abp.signalr-client.js:107 at abp.signalr-client.js:110

Please help...

I created a sample SignalR project (I am not talking about ABP or Module Zero Here). Normal ASP.Net Core Application.

My startup class has following code.

app.Map("/signalr", map => { map.UseCors(CorsOptions.AllowAll); var hubConfiguration = new HubConfiguration{}; map.RunSignalR(hubConfiguration); });

Now there is another application (say windows application) who wanted to connect to my application using signalR. So the windows application use the following code to connect to my Hub hubConnection = new HubConnection("http://localhost:18444/signalr/hubs");

Please see the URL of Hub in the above code. When I browse the above URL (<a class="postlink" href="http://localhost:18444/signalr/hubs">http://localhost:18444/signalr/hubs</a>), it gives me following output...

    proxies['myHub'] = this.createHubProxy('myHub');

    return proxies;
};

signalR.hub = $.hubConnection("/signalr", { useDefaultPath: false });
$.extend(signalR, signalR.hub.createHubProxies());

}(window.jQuery, window));

Question is What would be my hub URL in Module Zero project. My startup class has following code: app.UseSignalR(routes => { //routes.MapHub<AbpCommonHub>("/signalr"); routes.MapHub<iVend365Hub>("/signalr"); });

Appreciate your response.
