在問一個單獨的問題之前，我已經做了大量的關於它的搜索，並在現有的stackoverflow question中添加了一條評論。SignalR Server錯誤「ConnectionId的格式不正確。」與SignalR-ObjC庫
我有一個SignalR集線器（都嘗試v 1.1.3和2.0.0-RC）。在我的服務器與下面的代碼：
[HubName("TestHub")]
public class TestHub : Hub
{
[Authorize]
public void TestMethod(string test)
{
//some stuff here
Clients.Caller.NotifyOnTestCompleted();
}
}
的問題仍然存在，如果我刪除授權屬性。
在我的iOS客戶端我嘗試用下面的代碼來調用它：
SRHubConnection *hubConnection = [SRHubConnection connectionWithURL:_baseURL];
SRHubProxy *hubProxy = [hubConnection createHubProxy:@"TestHub"];
[hubProxy on:@"NotifyOnTestCompleted" perform:self selector:@selector(stopConnection)];
hubConnection.started = ^{
[hubProxy invoke:@"TestMethod" withArgs:@[@"test"]];
};
//received, error handling
[hubConnection start];
當應用程序啓動用戶沒有登錄且沒有開放SignalR連接。用戶通過在使用WebSecurity.Login方法的服務器中調用登錄服務來登錄。如果登錄服務返回成功，我將上面的呼叫轉到SignalR Hub，然後我得到服務器錯誤500，描述爲「ConnectionId的格式不正確」。
完整的服務器堆棧跟蹤如下：

我明白這是某種形式的身份驗證和用戶身份不匹配的，但到現在爲止我還沒有發現任何解決它的辦法。所有其他問題都建議在用戶身份更改時停止打開的連接，但正如我上面提到的，在用戶成功登錄之前，我沒有打開連接。
任何幫助將不勝感激。 謝謝。
您是否找到了解決方案？我有同樣的問題。 – tremolo
我得到這個錯誤約5次5。所以有時候，連接不會在服務器上產生connectionId錯誤，但大多數情況下它都會產生連接錯誤。雖然我沒有任何身份驗證過程。 – tremolo
@tremolo：對不起，尚未解決。 – ozzotto
