node.js从http请求对象获取客户端IP [英] node.js get client IP from http request object

问题描述

如何从http req对象获取客户端IP地址？

How can I get the clients IP address from the http req object?

IE：

   var util = require('util'),
    colors = require('colors'),
    http = require('http'),
    httpProxy = require('../../lib/node-http-proxy');

//
// Http Server with proxyRequest Handler and Latency
//
var proxy = new httpProxy.RoutingProxy();
http.createServer(function (req, res) {
  // GET IP address here
  // var ip = ??
  var buffer = httpProxy.buffer(req);
  setTimeout(function () {
    proxy.proxyRequest(req, res, {
      port: 9000,
      host: 'localhost',
      buffer: buffer
    });
  }, 200);
}).listen(8004);

推荐答案

它应该只是 req .connection.remoteAddress
