异步控制器（MVC），长时间运行的过程和QUOT;停止＆QUOT; [英] Async Controllers (MVC), long running process with "stops"

问题描述

我感兴趣的是运行一个漫长的过程，我想尽快更新UI的结果开始进来，而不是等待它完成。

I'm interested in running a long process, I want to update the UI as soon as results start coming in and not wait for it to finish.

我会如何呢？我读过有关异步控制器，但他们似乎并没有有任何内置的用于这一目的。

How would I go about this? I've read about Async controllers but they don't seem to have anything built-in for this purpose.

只是将结果保存在应用/ Session对象的结果出来并使用轮询的客户端？我能想到的，可能出错多种方式（如用户关闭网页，以及对象停留在应用程序对象永远 - 需要管理这些到期对象自己，额外的服务器负载进行轮询，等等）。

Just save the results in the Application/Session object as the results come in and use polling from client side? I can think of several ways that could go wrong (like user closes page, and the object stays in Application object forever - need to manage expiration of these object myself, extra server-load for polling, etc).

有什么想法？

感谢您

推荐答案

我是想解决类似的东西（报告从长时间运行的服务器操作返回给客户端的实时进度）近日，它原来的 SignalR 是非常适合这种情况。

I was trying to solve something similar (reporting real-time progress from a long running server operation back to the client) recently and it turned out SignalR is a perfect fit for this situation.

基本上它是一个库包长轮询以及Web套接字，使用（透明）任何可用的服务器和客户端。

Basically it is a library wrapping long-polling and Web Sockets, using (transparently) whatever is available on server and client.

我只有用它很好的经验，到目前为止。

I only have good experience with it so far.
