nginx 静态资源服务

1.文件压缩

location ~ .*\.(jpg|gif|png)$ {
        gzip on(开启);
        gzip_http_version 1.1(版本);
        gzip_comp_level 2(压缩比);
        gzip_types(文件类型) text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
        root  /opt/app/code/images;
    }

　　

2.压缩gzip文件的预读功能

location ~ ^/download {
        gzip_static on(开启);
        tcp_nopush on;
        root /opt/app/code;
    }

　　

3.浏览器缓存原理

 location ~ .*\.(htm|html)$ {
        add_header Access-Control-Allow-Origin(跨域访问的请求域名) *(表示所有); 
        add_header Access-Control-Allow-Methods(跨域访问的请求方法) GET,POST,PUT,DELETE,OPTIONS;
        expires 24h(缓存周期);
        root  /opt/app/code;
    }

4.静态代理图片和视频示例

server {
    listen       8008;
    server_name  192.168.160.99;

    location /image_video/ {
       add_header Access-Control-Allow-Origin *;   # 跨域请求域名
       add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;  # 运行请求
       expires 24h;  # 缓存时间
       root  /nas/cloud.shunwang.com/;   # 访问路径
       autoindex on;    # 开启浏览目录权限：autoinedx on，默认是off；
   }
}
