推荐答案
我想你所谈论的是一个流的请求。
看看这个 http://strongloop.com/strongblog/streaming -chunked-HTML节点-JS-数据/ 。
I think what you are talking about is a streamed request. Take a look at this http://strongloop.com/strongblog/streaming-chunked-html-node-js-data/.
而在前端有一个叫EventSource的Javascript API第方法可以读取流响应或别人提到的,如果你需要双向通信,您可以使用套接字。
And in the front-end there is a Javascript API method called EventSource that can read a streamed response or as someone else mentioned you can use sockets if you need bi-directional communication.
