 4 | ## 用法:
 5 | 
 6 | 把图片的后缀名改成zip再上传到蓝奏云上，获取文件的分享链接如<https://www.lanzous.com/i6aa3hg> ，再自己构成链接<http://1787005804808765.cn-shanghai.fc.aliyuncs.com/2016-08-15/proxy/img_url/main/img?url=https://www.lanzous.com/i6aa3hg>，这就是图床的链接。

 8 | ## 原理：
 9 | 
10 | <http://1787005804808765.cn-shanghai.fc.aliyuncs.com/2016-08-15/proxy/img_url/main/img?url=https://www.lanzous.com/i6aa3hg>， 其实就是我服务器通过解析分享链接然后重定向下载直链，从而获取资源，你也可以通过这个直接获取其它文件的下载直链，不限于做图床。
