早期使用Node.js和Express刷新
问题描述：
我如何实现Express的早期刷新(成块的传输编码)?
How do I realise early flush (chuncked transfer encoding) with Express?
我发现的所有示例都在处理http模块，您可以在其中调用响应对象的write()方法，并以这种方式分段发送数据.
All examples I have found are dealing with the http module, where you can call the write() method of the response object and that way send data piece-wise.
答
您仍然可以将write与Express一起使用:
You can still use write with Express:
app.get('/test', function(req, res) {
var count = 0;
var interval = setInterval(function() {
if (count++ === 5) {
clearInterval(interval);
res.end();
return;
}
res.write('This is line #' + count + '\n');
}, 1000);
});
