Signalr和Nancyfx集成

Question

我的应用程序流程如下(为简洁起见,简化):

1. 用户从"/ page1"获取页面
2. 用户在页面上执行操作(添加文本,单击等等),而Signalr将此数据传送到服务器,后者在后台执行繁重的计算,并将结果返回到页面(让我们称之为"X" ").
3. 当用户完成页面后,他点击了Nancy返回的"/ page2"链接.此页面使用依赖于X的Model构建.

那么,我如何基于X构建该模型？信号器如何以Nancy可以接收的方式写入用户会话？

(我正在寻找一种"干净"的方式)

Answer 1

在Signalr和Nancy的正式整合之前,我就是这样.基本上,我在两者之间共享一个IOC容器,并使用一个将用户映射到状态的对象(单例生存期).

如何使用内置的TinyIOC共享IOC容器:

1. 扩展Signalr的DefaultDependencyResolver

   public class TinyIoCDependencyResolver : DefaultDependencyResolver
   {
       private readonly TinyIoCContainer m_Container;
   
       public TinyIoCDependencyResolver(TinyIoCContainer container)
       {
           m_Container = container;
       }
   
       public override object GetService(Type serviceType)
       {
           return m_Container.CanResolve(serviceType) ? m_Container.Resolve(serviceType) : base.GetService(serviceType);
       }
   
       public override IEnumerable<object> GetServices(Type serviceType)
       {
           var objects = m_Container.CanResolve(serviceType) ? m_Container.ResolveAll(serviceType) : new object[] { };
           return objects.Concat(base.GetServices(serviceType));
       }
   }
   

2. 用我们新的替换Signalr的默认DependencyResolver

   public class Bootstrapper : DefaultNancyBootstrapper
   {
       protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)
       {
           CookieBasedSessions.Enable(pipelines);
   
           // Replace UserToStateMap with your class of choice
           container.Register<IUserToStateMap, UserToStateMap>();
   
           GlobalHost.DependencyResolver = new TinyIoCDependencyResolver(container);
           RouteTable.Routes.MapHubs();
       }
   }
   

3. 将IUs​​erToStateMap添加为集线器和Nancy模块中的依赖项

   public class MyModule : NancyModule
   {
       public MyModule(IUserToStateMap userToStateMap)
       {
           Get["/"] = o =>
           {
               var userId = Session["userId"];
               var state = userToStateMap[userId];
               return state.Foo;
           };
       }
   }
   
   public class MyHub : Hub
   {
       private readonly IUserToStateMap m_UserToStateMap;
   
       public MyHub(IUserToStateMap userToStateMap)
       {
           m_UserToStateMap = userToStateMap;
       }
   
       public string MySignalrMethod(string userId)
       {
           var state = userToStateMap[userId];
           return state.Bar;
       }
   }
   

我真正想要的是一种基于连接ID或类似的东西在两者之间轻松共享状态的方法,但同时这个解决方案对我有用.
