這次的案例是利用阿里云oss2進(jìn)行簡單的bucket查詢以及上傳下載等基礎(chǔ)操作
- 對象存儲
對象存儲的概念我就不做太多概述了，詳情可以參考阿里云 - sdk
python的sdk不僅提供對文件的處理丹允，包括其它內(nèi)容比如圖片也有很好的支持锻梳，可以實現(xiàn)對圖片在線縮放、水印等一系列操作咐熙，詳情可參考官方圖片處理文檔 - 文件處理代碼

- 這里是小編用python3實現(xiàn)的簡單功能射亏，具體細(xì)節(jié)大家看注釋應(yīng)該都能理解命斧，主要是對上傳下載地址路徑的板塊可以詳細(xì)注意一下田晚，小編當(dāng)時也有點(diǎn)混亂，所以專門用了測試文件來調(diào)試這版塊的內(nèi)容国葬，大家也可以參考一下贤徒，github里面有其他版本的代碼，歡迎參考汇四、建議
- 如果內(nèi)容中有疑問歡迎留言或者參考：
