OnConnected引發異常 - 我如何刪除連接？

Question

我有一個類繼承PersistentConnection。當我覆蓋OnConnected時，我檢查了一些傳入的查詢字符串參數，以確保用戶已通過身份驗證。如果沒有，我會拋出一個異常，但客戶端仍然被認爲是連接的。我如何從連接的客戶列表中刪除客戶端？

public class NotificationConnection : PersistentConnection 
{ 
    protected override Task OnConnected(IRequest request, string connectionId) 
    { 
     if (String.IsNullOrWhiteSpace(request.QueryString["example"])) 
      throw new SecurityException("whatever"); 

     return base.OnConnected(request, connectionId); 
    } 

    protected override Task OnDisconnected(IRequest request, string connectionId) 
    {    
     return base.OnDisconnected(request, connectionId); 
    } 
} 

Answer 1

考慮更改設計使用由signalr露出來驗證用戶的方法進行身份驗證，他們對永久連接權利

protected override bool AuthorizeRequest(IRequest request) 
    { 
     return request.User != null && request.User.Identity.IsAuthenticated; 
    } 

Answer 2

爲什麼不直接發送消息給客戶端，告訴它斷開連接？例如

在服務器上。

if (String.IsNullOrWhiteSpace(request.QueryString["example"])) 
{ 
    Connection.Send(connectionId, "Close"); 
} 

然後在JS客戶端上做類似的事情;

connection.received(function(data) { 
    if (data === "Close"){ 
     connection.stop(); 
     // send the user to another page with window.location or warn them that their connection has been stopped. 
    } 
}); 

在.net客戶端上;

connection.Received += data => 
{ 
    if (data == "Close") 
    { 
     connection.stop(); 
    } 
};
