2、爬虫遭遇StackPath反爬的应对之策
3、JS逆向之某货车公共平台模拟免登陆

import execjs

with open('qiche.js') as rr:
    js_str = rr.read()

pwd = input(f'请输入密码')
password = execjs.compile(js_str).call('h_encrypt', pwd)
print(password)

4、python图片验证码识别muggle-ocr

pip install -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com muggle-ocr

5、结合起来 我想成为胖子
