Python + selenium + requests实现12306全自动抢票，验证码破解加自动点击！！！！！

测试结果： 

整个买票流程可以再快一点，不过为了稳定起见，有些地方等待了一些时间

完整程序，拿去可用 
整个程序分了三个模块：购票模块（主体）、验证码识别模块、余票查询模块 
购票模块：

from selenium import webdriver

time.sleep(3)
button2 = browser.find_element_by_id('normalPassenger_0') #按实际情况，可自行修改，这里就选择的第一个常用联系人，
#第二个是normalPassenger_1，依此类推
button2.click()
button3 = browser.find_element_by_id('submitOrder_id')
time.sleep(1)
button3.click()
