c# - Signalr 创建到两个不同集线器的两个连接

Question

我有两个集线器，我正在尝试从服务器建立到它们的两个连接:

    var hubConnection1 = new HubConnection("http://localhost:14382");
    var proxy1 = hubRestaurantConnection.CreateHubProxy("Hub1");
    hubConnection1.Start().Wait();

    var hubConnection2 = new HubConnection("http://localhost:14382");
    var proxy2 = hubConnection.CreateHubProxy("Hub2");
    hubConnection2.Start().Wait();

hubConnection2.Start().Wait() 调用总是崩溃并出现异常:

    StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
    {
     Transfer-Encoding: chunked
     X-SourceFiles: =?UTF-8?B?QzpcZGV2XHdlYjJcRmxpcGRpc2hXZWJcRmxpcGRpc2guV2ViXHNpZ25hbHJcc3RhcnQ=?=

    }

    Exception Details: Microsoft.AspNet.SignalR.Client.HttpClientException: StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

    }

我之所以有两个集线器，是因为一个给有管理员权限的用户使用，第二个给其他用户使用，它有不同的方法。

来自 javascript 客户端的连接似乎工作正常。我知道集线器共享一个连接，但从我的设计角度来看这没有问题。是错误还是我做错了什么？

我也试过交换创建集线器代理的顺序，但异常只发生在同一个代理上。

您使用相同的 HubConnection 创建多个 hubproxies:

var hubConnection = new HubConnection("http://localhost:14382");
var proxy1 = hubConnection.CreateHubProxy("Hub1");
var proxy2 = hubConnection.CreateHubProxy("Hub2");
hubConnection.Start().Wait();
