  1. Load Balancer->Attributes, X-Forwarded-For Header set to Append
  2. 在nginx中 
    server {
        # other configuration
        real_ip_header X-Forwarded-For;
        set_real_ip_from 0.0.0.0/0;

        location / {

         proxy_pass http://yourwebsite.com;

         # Overriding X-Forwarded-For with value of $remote_addr
         proxy_set_header X-Forwarded-For $remote_addr;
        }
}
  3. 應用 (Node.js+Express)
    4. app.get("/user_ip", (req, res) => {
  const ip =
    req.headers["x-forwarded-for"] ||
    req.headers["x-real-ip"] ||
    req.socket.remoteAddress;
  res.json({ ip: ip });
});
