阿里雲 ECS 經過 Nginx 反向代理到 OSS 走內網流量

走內網，減小流量費用開銷，控制請求帶寬

NGINX 配置：

server {
    listen 80;
    server_name static.bookstack.cn;
    client_max_body_size 128M;
    location / {
        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_set_header X-NginX-Proxy true;
