获取请求的 ip 地址

• 获取 ip 地址
  • 正常: req.ip
  • 使用 nginx 进行了反向代理

    1. 设置niginx,下面两个这个

       shell script proxy_pass http://127.0.0.1:5555 proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; // 这个 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; // 这个 proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";

    2. 后端自定义函数

        exports.ip = req => {
            return req.headers['x-forwarded-for'] ||
            req.ip ||
            req._remoteAddress ||
            (req.socket &&
                (req.socket.remoteAddress ||
                (req.socket.socket && req.socket.socket.remoteAddress)
                )
            );
        };
       

    3. ip 获取 complete.
