Express-req.ip返回127.0.0.1

Question

我的express服务器运行在端口3000上，反向代理是nginx。

ip总是返回127.0.0.1，而req.ips返回一个空数组

var ip_addr = req.headers['X-FORWARDED-FOR'] || req.connection.remoteAddress;

server {
    listen 80;
    server_name localhost;
    access_log /var/log/nginx/dev_localhost.log;

    location / {
        proxy_pass http://localhost:3000;
        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;
    }
}

您需要将适当的x-forwarded-for标头传递给上游。将以下行添加到上游配置中：

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
