如何将请求IP从NGINX转发到节点。js应用程序？

Question

我有NGINX作为反向代理运行，它将所有超文本传输协议和https流量转发到我的node.js应用程序，该应用程序监听localhost： port

然而，我的问题是节点。js应用程序将所有传入请求视为来自：：ffff:127.0。0.1

如何更改NGINX配置，使真正的IP能够通过并转发到节点。js应用程序？

server {
    listen 80;
    listen [::]:80;
    listen 443;
    listen [::]:443;

    root /var/www/example.com/html;
    index index.html index.htm;

    server_name example.com;

location / {
proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://localhost:myport;
    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;
}

 # Requests for socket.io are passed on to Node on port x
  location ~* \.io {
  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;

  proxy_pass http://localhost:myport;
  proxy_redirect off;

  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
}


}

编辑：快车。js/node。js应用程序处理请求。ip和应用程序。启用（“信任代理”）；启动时

Answer 1

考虑到以上NGINX配置，这解决了它。

var ip = req.headers['x-real-ip'] || req.connection.remoteAddress;

Answer 2

表示js官方网站有这个指南。说明：

1. app.set（信任代理，true）in js.
2. proxy_set_headerX-转发-对于$remote_addr在nginx.conf
3. 您现在可以从req.ip属性
读取客户端IP地址
