node 代码

var express = require('express'); var app = express(); var os = require('os'); var http = require('http'); var cors = require('cors'); app.use(cors()); app.get('/', cors(),function(req, res){ var ip = getClientIp(req).match(/\d+\.\d+\.\d+\.\d+/); console.log(ip); }); function getClientIp(req) { return req.headers['x-forwarded-for'] || req.connection.remoteAddress || req.socket.remoteAddress || req.connection.socket.remoteAddress; } app.listen(8081); console.log('listening on port http://localhost:8081/');

nginx 代理

server { listen 80; server_name nnn.com; location / { proxy_set_header X-real-IP $remote_addr; proxy_pass http://127.0.0.1:8081; } access_log /home/wwwlogs/nnn.com.log access; }

直接访问服务器的ip 是正常返回客户端的ip

而访问 nginx 代理转向 的域名地址 返回的ip 却是 127.0.01

nginx 转向的 proxy_pass 地址是多少 ，返回的就是多少

node 如何更好的绑定域名呢？
