Node Js的response.write问题

问题描述

当我出于某种原因尝试利用http流连接时，直到我调用时才会刷新写入response.end()
我直接从演示中获取代码，不明白我的问题是什么.
当我卷曲到服务器时，标题是正确的.

When I try to utilize http stream connection for some reason write does not flush until I callresponse.end()
I am taking the code straight from the demo and do not understand what my problem is.
When I curl to the server my headers are correct.

HTTP/1.1 200 OK
Content-Type: text/plain
Connection: keep-alive
Transfer-Encoding: chunked


var http = require('http');
    http.createServer(function (req, res) {
      res.writeHead(200, {'Content-Type': 'text/plain'});
      res.write('hello');
      res.write(':');
      setTimeout(function(){
          res.end('World\n')},
          2000);
    }).listen(1337, "127.0.0.1");
    console.log('Server running at http://127.0.0.1:1337/');

服务器为什么不发送写数据?

Why is the server not sending the write data?

推荐答案

我似乎是浏览器特有的行为-Firefox会立即显示数据("Hello:")，而chrome似乎会缓冲并等待响应结束.请注意，如果您一开始写入更多数据(例如，我写了1000个"Hello")，chrome也会立即显示数据.

I seems to be browser specific behavior -- firefox shows the data ("Hello:") immediately while chrome seems to buffer and wait until the response is ended. Note that chrome also shows the data immediately if you write more data at first (e.g. I wrote 1000 "Hello"s).
