python-爬虫之随机生成请求头User-Agent、验证码识别

目录

User-Agent

验证码识别

User-Agent

安装库： pip install fake_useragent

生成随机的User-Agent出现 BUG，一般禁用浏览器缓存问题即可(参数use_cache_server=False)

from fake_useragent import UserAgent

ua = UserAgent(use_cache_server=False)
for i in range(10):  # 随机生成十个User-Agent
    headers = {'User-Agent': ua.random}
    print(headers)

验证码识别

安装库：pip install ddddocr

import ddddocr as dr

ocr = dr.DdddOcr()
with open('./IMG/33.png', 'rb') as f:
    read_img = f.read()
code = ocr.classification(read_img)
print(code)
