从12306上面爬取图片（最新方法2020年3月）

网址打开是base64编码所以需要一点小操作hhh
很简单看看完事

import requests
import re
import base64
from urllib.parse import quote

__author__ = '豪哥哥'
headers = {
    'Host': 'kyfw.12306.cn',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0',
    'Referer': 'https://kyfw.12306.cn/otn/resources/login.html'

}

session = requests.Session()
    url = 'https://kyfw.12306.cn/passport/captcha/captcha-image64?login_site=E&module=login&rand=sjrand'
    imgCode = session.get(url, headers=headers, verify=True)  # 保证ssl认证安全
    image_base64 = eval(imgCode.text)
    print(image_base64['image'])
    img_deode = base64.b64decode(image_base64['image'])
    with open('code.png', 'wb') as fn:
        fn.write(img_deode)
