asp.net-mvc – Context.User.Identity.Name为null与SignalR 2.X

发布时间：2020-12-15 18:45:22 所属栏目：asp.Net 来源：网络整理

导读：这让我疯狂。我正在使用最新的signalR版本(2.0.2)。这是我的中心码(OnConnected) public override Task OnConnected() { //User is null then Identity and Name too. Connections.Add(Context.User.Identity.Name,Context.ConnectionId); return base.OnCo

这让我疯狂。

我正在使用最新的signalR版本(2.0.2)。这是我的中心码(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Controller的登录方式：

[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上遇到这个问题，我甚至没有在那里。

我正在使用MCV5模板。

你有什么想法有什么问题吗？

解决方法

我找到了最终的解决方案，这是我的OWIN启动类的代码：

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());    
    }

让我自己喝咖啡，我以为“在验证后映射SignalR如何，瞧！现在它按照预期工作。

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();    
    }
