需求：
1.實現代理s3的nginx緩存服務器
2.實現nginx代理服務器的 / 路徑到s3的指定目錄映射，即 / -> bucket-name.s3-website-ap-northeast-1.amazonaws.com/
最重要的就是在 server { } 中加上底下這段:
引用:
location / {
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header Authorization '';
proxy_set_header Host bucket-name.s3-website-ap-northeast-1.amazonaws.com;
proxy_hide_header x-amz-id-2;
proxy_hide_header x-amz-request-id;
proxy_hide_header x-amz-meta-server-side-encryption;
proxy_hide_header x-amz-server-side-encryption;
proxy_hide_header Set-Cookie;
proxy_ignore_headers Set-Cookie;
proxy_intercept_errors on;
add_header Cache-Control max-age=31536000;
proxy_pass http://bucket-name.s3-website-ap-northeast-1.amazonaws.com/;
}
這樣就可以囉～
