恰巧发现有个叫“earthlivesharp”,可用将日本向日葵8号卫星的地球实时图片设为屏保。向日葵8号卫星的地球实时图片官网为:,earthlivesharp的项目地址是:https://github.com/bitdust/earthlivesharp
为了减轻向日葵8号的服务器负担,同时也是提高地球实时图片的获取成功率,需要使用cloudinary来做cdn。注册配置都在软件里有说明。

目前earthlivesharp暂时没有清理cloudinary的cdn图片缓存的功能,于是我用python写了一个,并尝试用gist管理,地址为:

同时,为了大家方便,顺便编译成了windows可执行文件,下载: https://pan.baidu.com/s/1c27fxeo 提取码:k33n
为了自己检索方便,顺便在这里附上python脚本源码,可以作为python如何使用restful接口的例子,相关工具类函数也便于参考。
