如何从iOS上的PhoneGap应用程序连接到SignalR集线器

How to connect to a SignalR hub from PhoneGap app on iOS?

本文关键字：连接 SignalR 集线器 应用程序 PhoneGap iOS 上的      更新时间：2023-09-26

我正在尝试为我运行的基本SignalR聊天服务器构建PhoneGap iOS客户端。当从浏览器中的页面访问它时，一切都很好，但我似乎无法从PhoneGap应用程序连接它。以下是我代码的相关部分:

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>

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

我已经浏览了大量的网站，讨论它的点点滴滴，但无法弄清楚。
