在结束响应之前如何输出数据? [英] How can I output data before I end the response?
问题描述
这是我在Chrome 11和Firefox 4中对其进行测试的代码段:
Here is my snippet I tested it in Chrome 11, and Firefox 4:
var http = require('http');
http.createServer(function(request, response){
// Write Headers
response.writeHead(200);
// Write Hello World!
response.write("Hello World!");
// End Response after 5 seconds
setTimeout(function(){
response.end();
}, 5000);
}).listen(8000);
如您所见,我使response.end()
超时,因此我可以测试response.write
是否在response.end
之前输出.以我的经验,虽然不是.
As you can see I timed out the response.end()
so I can test if response.write
is outputted before the response.end
. In my experience though it is not.
是否有一种方法可以在结束响应之前输出数据,就像以数据包形式发送数据一样?
Is there a way to output the data before ending the response, something like sending the data in packets?
推荐答案
如果将内容类型更改为text/plain,例如:
If you change the content type to text/plain -- e.g:
// Write Headers
response.writeHead(200, {'Content-Type': 'text/plain'});
然后firefox将立即显示内容. Chrome似乎仍然可以缓冲(如果您编写更多内容,则chrome会立即显示它).
then firefox will show the content immediately. Chrome still seems to buffer (if you write a bunch more content, chrome will show it immediately).
