WebSocket 模板

适合 Socket.IO、WebSocket 网关、实时消息服务。

替换：

• example.com
• 127.0.0.1:3000

server {
    listen 80;
    listen [::]:80;
    server_name example.com;

    location /socket.io/ {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_read_timeout 3600s;
        proxy_send_timeout 3600s;
    }
}

如果 WebSocket 和普通 HTTP 复用根路径，把 location /socket.io/ 改成实际路径。
