对于 SignalR 2.X.X，Context.User.Identity.Name 为空.如何解决? [英] Context.User.Identity.Name is null with SignalR 2.X.X. How to fix it?

问题描述

这让我发疯.

我使用的是最新的 signalR 版本 (2.0.2).这是我的集线器代码 (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");
        }

我发现有些人在 OnDisconnected 上遇到了这个问题，我什至没有做到.

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

我使用的是 MCV5 模板.

I'm using MCV5 template.

你知道出了什么问题吗?

Do you have any idea what is wrong?

推荐答案

我找到了最终的解决方案，这是我的OWIN启动类的代码:

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());    
    }

给自己泡了些咖啡，我想在身份验证后映射 SignalR 怎么样，瞧！ 现在它按预期工作了.

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();    
    }
