Question

我正在使用ASP.NET SignalR开发ASP.NET MVC应用程序。但我收到错误，无法找到解决方法。这是我的global.asax类，当我启动项目时，我在这里遇到错误：

 public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start(object sender, EventArgs e)
    {
        AreaRegistration.RegisterAllAreas();

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

        //This is what I added and this is where i am getting the error.
        RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");
    }
}

我的连接类就像在底部

public class NfcConnection : PersistentConnection
{
    protected override Task OnConnected(IRequest request, string connectionId)
    {
        string msg = string.Format(
            "A new user {0} has just joined. (ID: {1})",
            request.QueryString["name"], connectionId);
        return Connection.Broadcast(msg);
    }

    protected override Task OnReceived(IRequest request, string connectionId, string data)
    {

        string msg = string.Format(
            "{0}: {1}", request.QueryString["name"], data);
        return Connection.Broadcast(msg);
    }
}

这是广播来自客户端的数据的部分。而且我的owin启动课就是这样;

 public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.MapSignalR();
    }

}

当我开始项目这一行

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

给我这个错误;

Error'System.Web.Routing.SignalRRouteExtensions.MapConnection<T>(System.Web.Routing.RouteCollection, string, string)' is obsolete: 'Use IAppBuilder.MapSignalR<TConnection> in an Owin Startup class.

我该如何解决这个问题？

Answer 1

卸下：

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

并改变：

app.MapSignalR();

为：

app.MapSignalR<NfcConnection>("/echo");

错误：SignalRRouteExtension.Mapconnection已过时。在Owin Startup类中使用MapSignalR
