如何从iOS上的PhoneGap应用程序连接到SignalR集线器?
问题描述:
我正在尝试为我运行的基本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,一切都很好,但我似乎无法从PhoneGap应用程序连接它。这里是我的代码的相关部分:如何从iOS上的PhoneGap应用程序连接到SignalR集线器?
服务器的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);
}
服务器的web.config
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"></modules>
</system.webServer>
</configuration>
服务器枢纽
public class ChatHub : Hub
{
public void Send(string name, string message)
{
Clients.All.broadcastMessage(name, message);
}
}

我已经经历了很多网站,谈论它的点点滴滴,但无法弄清楚。
在此先感谢,杰森

感谢文章dfowler。我实际上已经删除了笔记中提到的cors行,作为我经历的许多调试步骤之一,但它没有任何区别。我实际上并没有遇到那篇特别的文章,它看起来很不错,所以我会仔细阅读它,看看有没有其他的东西可以帮助。 – Jason 2013-05-13 15:26:01
你有没有碰运气?我期待着测试同样的事情。 – user441521 2015-02-10 00:32:17
