Node.js：在检索http请求主体之前断开http请求连接 [英] Node.js: Disconnect http request connection before the http request body has been retrieved

问题描述

我正在用Node.js编写一个http服务器。

I'm writing a http server with Node.js.

我有一个客户端通过HTTP POST（multipart / data）将一个大文件上传到这个服务器。

I have a client to upload a large file to this server via HTTP POST(multipart/data).

我想接受唯一使用有效文件名上传文件的连接。（我有一些条件。）在服务器检索数据之前应该断开无效的文件名连接。

I want to accept the only connection which upload the file with valid filename.(I have some conditions.) The invalid filename connection should be disconnected before the server retrieves the data.

我不知道如何断开http请求连接并返回正确的http响应。

I have no idea how to disconnect the http request connection and return the proper http response.

http请求只有req.pause（）方法，这不是一个答案。
如果我调用req.connection.end（），则response.writeHeader（）/ write（）不会发送响应。

The http request has only req.pause() method which isn't an answer. and if I call req.connection.end(), the response.writeHeader()/write() doesn't send the response.

推荐答案

我认为以下应该可以工作，因为请求和响应对象共享同一个套接字......但它似乎不可靠。也许这是节点中的错误？

I would have thought the following should work since the request and response objects share the same socket... but it seems unreliable. Maybe it's a bug in node?

request.connection.allowHalfOpen = false
response.writeHead 500, 
    'Access-Control-Allow-Origin' : '*'
response.end()
