恰巧發(fā)現(xiàn)有個(gè)叫“EarthLiveSharp”，可用將日本向日葵8號(hào)衛(wèi)星的地球?qū)崟r(shí)圖片設(shè)為屏保。向日葵8號(hào)衛(wèi)星的地球?qū)崟r(shí)圖片官網(wǎng)為：http://himawari8.nict.go.jp/，EarthLiveSharp的項(xiàng)目地址是：https://github.com/bitdust/EarthLiveSharp。
為了減輕向日葵8號(hào)的服務(wù)器負(fù)擔(dān)，同時(shí)也是提高地球?qū)崟r(shí)圖片的獲取成功率，需要使用cloudinary來做CDN。注冊(cè)配置都在軟件里有說明。
目前EarthLiveSharp暫時(shí)沒有清理cloudinary的CDN圖片緩存的功能，于是我用python寫了一個(gè)，并嘗試用gist管理，地址為：https://gist.github.com/creke/c5a8a18fa41b8f5c1a0719a7e0cf4de6
同時(shí)，為了大家方便，順便編譯成了Windows可執(zhí)行文件，下載： https://pan.baidu.com/s/1c27fXEo 提取碼：k33n
為了自己檢索方便，順便在這里附上python腳本源碼，可以作為python如何使用RESTful接口的例子，相關(guān)工具類函數(shù)也便于參考。
