我有自己的VPS服务器，我在node.js中有脚本，它显示访问者的IP，但是当我访问网站时，我总是在控制台中获得本地IP地址(127.0.0.1)。 我用的是Nginx。

知道吗？

node.js脚本:

#!/usr/bin/env nodejs

  const http = require('http');

  const host = '127.0.0.1';

  const port = 8080;

  const server = http.createServer((req, res) => {

  res.statusCode = 200;

  res.setHeader('Content-Type', 'text/plain');

  var ip = (req.headers['x-forwarded-for'] || '').split(',').pop().trim() || 
  req.connection.remoteAddress || req.socket.remoteAddress || req.connection.socket.remoteAddress;


console.log(`IP = ${ip}`);

});

server.listen(port, host);

Nginx代理/报头配置:

server {

  listen 80 default_server;

  listen [::]:80 default_server;

  root /var/www/html;

    
  index index.html index.htm index.nginx-debian.html;

  server_name _;

  location / {
            
           try_files $uri $uri/ =404;
           proxy_pass http://127.0.0.1:8080;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'upgrade';
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
 }
 }
