我正在尝试为我正在运行的基本 SignalR 聊天服务器(ASP.NET MVC 4)构建 PhoneGap iOS 客户端。从浏览器中的页面访问它时一切正常,但我似乎无法从 PhoneGap 应用程序连接它。这是我的代码的相关部分:

服务器 global.asax

protected void Application_Start()
{
    // Register the default hubs route: ~/signalr  * This must be registered before any other routes
    RouteTable.Routes.MapHubs(new HubConfiguration { EnableCrossDomain = true });

    AreaRegistration.RegisterAllAreas();

    WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
}

服务器 web.config

<configuration>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true"></modules>
    </system.webServer>
</configuration>

服务器集线器

public class ChatHub : Hub
{
    public void Send(string name, string message)
    {
        Clients.All.broadcastMessage(name, message);
    }
}

PhoneGap 客户端

              $('#sendmessage').click(function () {

                  var encodedMsg = $('<div />').text($('#message').val()).html();
                  // Call the Send method on the hub.
                  chat.send(encodedName, encodedMsg);
                  // Clear text box and reset focus for next comment.
                  $('#message').val('').focus();
               });
          }).fail(function () {
              alert("Failed to connect");
          });
        });
        </script>
</body>

我浏览过很多网站,这些网站都在谈论它的点点滴滴,但无法弄清楚。

在此先感谢,杰森
