Context.User.Identity.Name为null与SignalR 2.X.X.如何解决呢？ [英] Context.User.Identity.Name is null with SignalR 2.X.X. How to fix it?

问题描述

这是推动我疯了。

我使用的是最新版本signalR（2.0.2）。这是我的枢纽code（OnConnected）

I'm using latest signalR release (2.0.2). This is my hub code (OnConnected)

        public override Task OnConnected()
        {
            //User is null then Identity and Name too.
            Connections.Add(Context.User.Identity.Name, Context.ConnectionId);
            return base.OnConnected();
        }

这是我的控制器的登录方法：

And this is my Controller's login method:

        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
        {
            if (ModelState.IsValid)
            {
              var user = await UnitOfWork.UserRepository.FindAsync(model.UserName,  model.Password);

                if (user != null)
                {
                    await SignInAsync(user, model.RememberMe);

                    return RedirectToLocal(returnUrl);
                }
            }

            TempData["ErrorMessage"] = Resources.InvalidUserNameOrPassword;

            // If we got this far, something failed, redisplay form
            return RedirectToAction("Index","Home");
        }

我发现，一些人正在对OnDisconnected这个问题上，我甚至不让它在那里。

I found that some people are having this issue on OnDisconnected, I don't even make it there.

我使用MCV5模板。

你有什么想法有什么不好？

Do you have any idea what is wrong?

推荐答案

我找到最终的解决方案，这是我OWIN启动类的code：

I found the final solution, this is the code of my OWIN startup class:

        public void Configuration(IAppBuilder app)
        {
        app.MapSignalR();

        // Enable the application to use a cookie to store information for the signed i user
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Home/Index")
        });

        // Use a cookie to temporarily store information about a user logging in with a third party login provider
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
        app.UseMicrosoftAccountAuthentication(new MicrosoftProvider().GetAuthenticationOptions());
        app.UseTwitterAuthentication(new TwitterProvider().GetAuthenticationOptions());
        app.UseFacebookAuthentication(new FacebookProvider().GetAuthenticationOptions());
        app.UseGoogleAuthentication(new GoogleProvider().GetAuthenticationOptions());    
    }

让自己喝杯咖啡，我觉得有关映射SignalR的认证后，瞧！ 现在是workign预期。的 <什么/ p>

Making myself some coffee, I thought "What about mapping SignalR AFTER the authentication, and voila! Now it's workign as expected.

        public void Configuration(IAppBuilder app)
        {
        // Enable the application to use a cookie to store information for the signed i user
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Home/Index")
        });

        // Use a cookie to temporarily store information about a user logging in with a third party login provider
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
        app.UseMicrosoftAccountAuthentication(new MicrosoftProvider().GetAuthenticationOptions());
        app.UseTwitterAuthentication(new TwitterProvider().GetAuthenticationOptions());
        app.UseFacebookAuthentication(new FacebookProvider().GetAuthenticationOptions());
        app.UseGoogleAuthentication(new GoogleProvider().GetAuthenticationOptions());

        app.MapSignalR();    
    }
