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:http://himawari8.nict.go.jp/,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:https://gist.github.com/creke/c5a8a18fa41b8f5c1a0719a7e0cf4de6
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。
