五、圖牀(github+jsDelivr)選擇，圖片上傳並生成鏈接

概述

拿到淘寶商品評論圖片後，需要上傳到圖牀進行顯示，找到了兩個免費的圖牀github和微博：

圖牀	優點	缺點
github	github提供RESTful api接口 可以使用jsDelivr加速	訪問速度比較慢，上傳比較慢
weibo	訪問速度較快	只能一張一張上傳 而且有的賬號不支持外鏈

實現

源碼文件

文件	介紹
github.py	封裝github RESTful API
main.py	啓動程序
settings.py	設置
uploader.py	使用github API上傳圖片

main.py

#如果圖片不存在，則直接退出

gh = GitHub(access_token=settings.TOKEN)
#切換工作目錄
downloadFolder = os.getcwd() + '\\' + settings.STORE_PATH
os.chdir(downloadFolder)
#循環上傳文件
for f in os.listdir(downloadFolder):
    Uploader(downloadFolder,f,gh).upload()
    os.chdir('..')
#重新切換工作目錄
os.chdir('..')
