验证码破解 | Selenium模拟登陆12306

12306官网登录的验证码破解比较简单,验证码是常规的点触类型验证码,使用超级鹰识别率比较高。

思路:

(1)webdriver打开浏览器;

(2)先对整个屏幕截屏,通过标签定位找到验证码图片,并定位到验证码图片的坐标,然后从先前截屏的图片中截取验证码部分的图片;

(3)通过超级鹰识别验证码上字的坐标;

(4)点击验证码图片上的字;

(5) 输入用户名和密码进行登录;

注意:将以下标红部分的账号等信息换成自己的即可成功

from selenium.webdriver import ActionChains
from chaojiying import  Chaojiying

# 用户名和密码是自己的12306账号的用户名和密码
