Node express 项目绑定域名后 获取不到客户ip公网了
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？

你设置了 proxy_pass，让 nginx 把对域名的访问转发到你设的 IP 上，nginx 照做了，你还想要什么其他结果？
用户访问域名时 DNS 已经解析到你的服务器公网 IP 上了，你又用 nginx 给转发出去了。如果你不需要转发，把 location / {} 里的内容删掉，并设置 root 访问目录
server {
listen 80;
server_name nnn.com;
root /data/html/www; // 程序根目录
}
req.headers[‘x-forwarded-for’] 相应的 nginx 也需要配置
location / {
proxy_pass http://localhost:3000;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
