Socket挂起，同时向Node-http-proxy Node.js发布请求

问题描述

我正在Node.js项目工作，我希望节点作为solr的代理

I'm working in Node.js Project and I want node to act as a proxy for solr

对于代理：我使用。
的问题是，代理工作出色的情况下获得请求，但如果发布请求，它导致插座挂起异常

For proxy: I used Node-http-proxy.the problem is that proxy work excellent in case of get requests but in case of post requests it results in socket hang up exception

这是一个我的样本节点代码

Here is a sample of my node code

var express = require('express');
var router = express.Router();

var http = require('http');
var httpProxy = require('http-proxy')

var proxyOptions = {
  host: "127.0.0.1",
  port: 8983
};
var proxy = httpProxy.createProxyServer(proxyOptions);

// It works excellent in GET request
router.get('/solr/*', function(req, res) {
  proxy.web(req, res, {
    target: 'http://' + proxyOptions.host + ':' + proxyOptions.port
  });
})

// the socket hang up in post request
router.post('/solr/*', function(req, res) {
  console.log('Post Request');
  proxy.web(req, res, {
    target: 'http://' + proxyOptions.host + ':' + proxyOptions.port
  });
})

这是节点控制台中的一段时间后的错误

And this is the error after some time in node console

Error: socket hang up
    at createHangUpError (http.js:1476:15)
    at Socket.socketOnEnd [as onend] (http.js:1572:23)
    at Socket.g (events.js:180:16)
    at Socket.emit (events.js:117:20)
    at _stream_readable.js:943:16
    at process._tickCallback (node.js:419:13)

有关问题原因的任何建议

Any suggestions about the cause of the problem

推荐答案

我认为问题来自中间件的顺序。在httpProxy之前使用bodyParser将会使用JSON body来分解请求，所以在BodyParser之前应该使用httpProxy。

I think the issue comes from the order of middleware. Using bodyParser before httpProxy will break the requests with JSON body, so httpProxy should be used before bodyParser.

你可能想检查有关bodyParser的更多信息。
