Null Context.User

Question

當我嘗試訪問我的Hub中的Context.User時，我一直得到Context.User爲空錯誤。我嘗試過在ConfigureAuth（）下移動app.MapSignalR（），但它導致SignalR根本不映射。我不確定在哪裏需要將我的cookie傳遞給SignalR。

SignalR是工作在我的應用程序將消息發送到所有的用戶我只是不能得到的onConnect覆蓋到沒有Context.User

Startup.CS

public partial class Startup 
{ 
    public void Configuration(IAppBuilder app) 
    { 
     app.MapSignalR(); 
     ConfigureAuth(app); 

    } 
} 

Startup.Auth工作。 CS

    private static string authority = aadInstance + tenantId; 

    public void ConfigureAuth(IAppBuilder app) 
    {

您需要更改此：

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

要這樣：

public void Configuration(IAppBuilder app) 
{ 
    ConfigureAuth(app); 
} 

再叫MapSignalR()裏面你ConfigureAuth()

你不能只是調用MapSignalR()ConfigureAuth()後的原因是由於該行：

app.MapWhen(context => !IsDataPath(context.Request), appBuilder => 

的來源問題在於MapWhen()方法分支請求管道，如果您只在Owin中調用app.MapSignalR()啓動時，您將在錯誤的請求管道中初始化SignalR。

所以你ConfigureAuth（）方法應該是這個樣子：

public void ConfigureAuth(IAppBuilder app) 
{ 
    app.MapWhen(context => !IsDataPath(context.Request), appBuilder => 
    { 
     appBuilder.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType); 

     appBuilder.UseCookieAuthentication(new CookieAuthenticationOptions()); 

     appBuilder.UseOpenIdConnectAuthentication(
      new OpenIdConnectAuthenticationOptions 
      { 
       ClientId = clientId, 
       Authority = authority, 
       PostLogoutRedirectUri = postLogoutRedirectUri, 

       Notifications = new OpenIdConnectAuthenticationNotifications() 
       { 
        SecurityTokenValidated = (context) => 
        { 
         ... 
        }, 
        AuthenticationFailed = (context) => 
        { 
         ... 
        }, 
       } 
      }); 

     appBuilder.MapSignalR(); 
    }); 
}
