五、图床(github+jsDelivr)选择，图片上传并生成链

概述

拿到淘宝商品评论图片后，需要上传到图床进行显示，找到了两个免费的图床github和微博：

实现

源码文件

main.py

# -*-coding: utf8 -*-
import os

import settings
from github import GitHub
from uploader import Uploader

#如果图片不存在，则直接退出
if os.path.exists(settings.STORE_PATH) == False:
    print('download folder not exists')
    exit(1)
#创建GitHub Api
gh = GitHub(access_token=settings.TOKEN)
#切换工作目录
downloadFolder = os.getcwd() + '\\' + settings.STORE_PATH
os.chdir(downloadFolder)
#循环上传文件
for f in os.listdir(downloadFolder):
    Uploader(downloadFolder,f,gh).upload()
    os.chdir('..')
#重新切换工作目录
os.chdir('..')

uploader.py
