Question

我一直潜伏着大约一个小时试图寻找解决方案或模式（标题参考）.. 让我举个例子来说明我的意思：

Client-to-Server: Hey, I want information about "ww2" //using jquery's ajax .post() method
Server-to-Client: Ok, got your request, prepare to receive data asynchronously.
Server-to-Client: "World War II happen in 1939 to 1945"
//after couple of seconds
Server-to-Client: "The Alliance won the war."
//some more delay
Server-to-Client: "bla bla bla"
Server-to-Client: "thats it, im done for now".

现在很明显，客户端将在使用jquery接收数据后立即显示数据。我的主要问题是，如何在服务器上的HttpPOST上调用Action并异步返回多个PartialView？

如果样品有任何其他方式/想法，我们将非常感激。

使用SignalR是一个选项

但如果您想自己做而不是从Controller继承您的控制器类，请从AsyncController继承它。从AsyncController继承的控制器可以处理异步请求，它们仍然可以为同步操作方法提供服务。

public class HomeController : AsyncController 
     {
         public void ExtensiveTaskActionAsync() 
         {
             AsyncManager.OutstandingOperations.Increment();
             Task.Factory.StartNew(() => DoExtensiveTask());
         }

         private void DoExtensiveTask()
        {
            Thread.Sleep(5000); // some task that could be extensive
            AsyncManager.Parameters["message"] = "hello world";
            AsyncManager.OutstandingOperations.Decrement();
        }


        public ActionResult ExtensiveTaskActionCompleted(string message) 
        {
            //task complete so, return the result
            return View();
        }
    }

使用未定义的延迟从服务器端向客户端多个PartialViews异步发送
