我有两个，一个在VisualStudio本地机器上运行的简单UWP应用程序和一个简单的AngularJS SPA。我还有一个基于OWIN的自托管服务器，运行在服务结构集群中。服务器使用web api和信号器

当我在本地机器上托管Service Fabric群集时，UWP应用程序和angular应用程序可以打开到服务器上信号集线器的连接。当我在Azure上托管Service Fabric群集时，客户端无法连接到信号集线器。我得到：

失败：WebSocket握手时出错：意外响应代码：400

启动类中的服务器端代码：

        public void Configuration(IAppBuilder appBuilder)
        {
            HttpConfiguration httpConfig = this.ConfigureWebApi();
            FileServerOptions fileServerOptions = this.ConfigureFileSystem(appBuilder);                           appBuilder.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
            appBuilder.UseWebApi(this.ConfigureWebApi());
            appBuilder.UseFileServer(fileServerOptions);
            appBuilder.MapSignalR();

服务器上的信号器集线器类：

    public class SensorDataHub : Hub
    {
        public void UpdateSensorData(SensorDataModel data)
        {
            Clients.All.updateChartData(data);
        }            
    }

UWP代码：

        private async void OpenSignalRConnection()
        {    
            //this.SensorDataHubCon = new HubConnection("http://localhost:80/");
            this.SensorDataHubCon = new HubConnection("http://rivutec.westeurope.cloudapp.azure.com/");
            this.SensorDataHubProxy = this.SensorDataHubCon.CreateHubProxy("SensorDataHub");

            await this.SensorDataHubCon.Start();
        }

AngularJS代码：

            var connection = $.hubConnection("http://localhost:80/");
            //var connection = $.hubConnection("http://test.server.com/");
            var proxy = connection.createHubProxy("SensorDataHub");

            proxy.on("updateChartData", function (data) {
                console.log(data.current);
            });

            connection.start()
                .done(function () { console.log('Now connected, connection ID=' + $.connection.hub.id); })
                .fail(function () { console.log('Could not Connect!'); });

如上所述，UWP客户端和angular客户端可以打开到

localhost

的集线器连接

但是，当我试图将UWP客户端连接到云上发布的信号集线器时，我收到了一个

。为什么我可以在本地主机上连接，而不能在云上连接？
在看不到更多代码的情况下，这只是一个玩笑，但是
基于这是一个“错误请求”错误，并且日志显示它在所有传输类型上都超时，我的直觉告诉我，在您的本地计算机上

当您为OWIN自身主机配置uri时，您告诉它绑定到localhost:80
当服务结构本地群集启动并运行
Stateful/lessService（或者我想你可以用Actors）来实现它
实例化OWIN自身主机
OWIN绑定到localhost:80，对localhost:80的请求正确路由到那里
有温暖的绒毛
但是，将群集移动到Azure时：
您想更改OWIN uri地址，因为localhost不再合适
所以你选择了“test.server.com”，或者其他什么
不过现在，集群不是在一台机器上，而是在Azure上
而且您想要使用的任何绑定都可能无效
这意味着，您的OWIN主机可能正在侦听“test.server.com”请求，但没有任何请求，因为没有DNS将“test.server.com”指向承载该服务（承载OWIN自身主机）的服务结构计算机
我阅读的一些文档指出，ServiceFabric框架有自己的名称服务器，这些服务器将ServiceFabric引用解析为实际的机器地址，这就是为什么您使用“fabric:”协议引用ServiceFabric服务，并让路由魔法在幕后发生。因此，同样的限制意味着您不能在不使用中间层的情况下直接公开ServiceFabric服务的HTTP端点（有关详细信息，请参见本文），这将限制您自托管和绑定到外部客户端可以使用的uri的能力

谈到在Azure Worker角色中使用OWIN自托管Web API，但该示例仅限于使用本地仿真器，并且似乎没有解决分配给端点的ip地址可能会在云中发生变化这一事实，这使得在客户端上很难可靠地寻址
如果您试图将信号集线器移动到服务结构，因为您希望能够利用服务结构的可伸缩性。当前推荐/支持的横向扩展SignalR的路径（看起来最适合您现有的）是使用Web角色和Azure Service Bus作为
