node.js – 如何使用PROXY协议获取客户端的真实IP地址？

I made a module caled proxywrap包装node.js服务器并自动从连接的流中剥离PROXY协议头,并将socket.remoteAddress和socket.remotePort重置为PROXY头中找到的值.

它与内置的服务器模块(如http,https和net)一起使用,作为模块的替代品：

var http = require('http'),proxiedhttp = require('proxywrap').proxy(http),express = require('express'),app = express(),srv = proxiedhttp.createServer(app); // instead of http.createServer(app)

app.get('/',function(req,res) {
    res.send('IP = ' + req.connection.remoteAddress + ':' + req.connection.remotePort);
});

srv.listen(80);

它也适用于spdy module：

var proxiedSpdy = require('proxywrap').proxy(require('spdy').server);

当然,你必须要enable the PROXY protocol on your ELB(或你的应用程序背后的任何代理).
