Question

我已经编写了几个SignalR / C＃原型，它们都可以在Windows上运行。这是一个非常简单的SignalR客户端，无法与Mono / Nginx服务器通信。问题是当我让Nginx运行我的单声道服务器代码然后尝试与客户端通信时。尝试建立连接时出现异常。

所有内容都在localhost上运行：9001

有人看到我的方法有什么问题吗？

服务器代码：

using Microsoft.AspNet.SignalR;
namespace SignalRMonoTesting
{
    public class ChatHub : Hub
    {
        public void Send(string name, string message)
        {
            // Call the broadcastMessage method to update clients.
            Clients.All.broadcastMessage(name, message);
        }
    }
}

启动代码：

using Microsoft.AspNet.SignalR;
using Microsoft.Owin.Cors;
using Owin;

namespace SignalRMonoTesting
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
            // Branch the pipeline here for requests that start with "/signalr"
            //app.Map("/signalr", map =>
            //{
            //    // Setup the CORS middleware to run before SignalR.
            //    // By default this will allow all origins. You can 
            //    // configure the set of origins and/or http verbs by
            //    // providing a cors options with a different policy.
            //    map.UseCors(CorsOptions.AllowAll);
            //    var hubConfiguration = new HubConfiguration
            //    {
            //        // You can enable JSONP by uncommenting line below.
            //        // JSONP requests are insecure but some older browsers (and some
            //        // versions of IE) require JSONP to work cross domain
            //        // EnableJSONP = true
            //    };
            //    // Run the SignalR pipeline. We're not using MapSignalR
            //    // since this branch already runs under the "/signalr"
            //    // path.

            //    hubConfiguration.EnableDetailedErrors = true;
            //    map.RunSignalR(hubConfiguration);
            //});
        }
    }
}

客户代码：

            $('#message').focus();
            // Start the connection.
            $.connection.hub.start().done(function () {
                $('#sendmessage').click(function () {
                    // Call the Send method on the hub.
                    chat.server.send($('#displayname').val(), $('#message').val());
                    // Clear text box and reset focus for next comment.
                    $('#message').val('').focus();
                });
            });
        });
    </script>
</body>
