location / {
autoindex on; # 启用目录索引

    add_header 'Access-Control-Allow-Methods' '*';
    add_header 'Access-Control-Allow-Headers' '*';
    add_header 'Access-Control-Max-Age' 1728000;

    # 预检请求的特殊处理
    if ($request_method = 'OPTIONS') {
        add_header 'Content-Type' 'text/plain; charset=utf-8';
        add_header 'Content-Length' 0;
        return 204;
    }
