爬虫 解决验证码问题

1.利用图像处理技术

2.用网上一些处理验证码的工具，如超级鹰

3.用已登录好的cookie

这次介绍selenium用超级鹰的工具来自动化处理验证码来完成登录

from chaojiying import Chaojiying_Client		#从超级鹰上下载库，导入
from selenium.webdriver import Edge
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

'''
# 用户中心>>软件ID 生成一个替换 96001
chaojiying = Chaojiying_Client('xxf09210', '15297954974xxf', '960690')
# 本地图片文件路径 来替换 a.jpg 有时WIN系统须要//
im = open('a.jpg', 'rb').read()
# 1902 验证码类型  官方网站>>价格体系 3.4+版 print 后要加()
print(chaojiying.PostPic(im, 1902))
# print chaojiying.PostPic(base64_str, 1902)  #此处为传入 base64代码

web.get('http://www.chaojiying.com/user/login/')
