2.下面demo是截取“去哪儿”官网的验证码

# -*- coding=utf-8 -*-
# CodeDemo.py
# PyCharm  Slade  2019/7/20
# import selenium,os
from selenium import webdriver
from PIL import Image


def aucthcode(coderddr):
  """
  传参验证码的Xpath
  页面全图为'code.png'     命名这个你们开心就好
  验证码截图名为"aucthcode.png
  :param coderddr:
  :return:
  """
  
  driver.save_screenshot('code.png')
  element = driver.find_element_by_xpath(coderddr)    # 获取验证码的div位置
  left = element.location['x'] +280
  top = element.location['y'] +81
  right = left + element.size['width'] + int(13)
  bottom = top + element.size['height'] + int(2)
  img = Image.open('code.png')
  imgcod = img.crop((left,top,right,bottom))     # 根据 div的长宽截图
  imgcod.save('aucthcode.png')
  print((left,top,right,bottom))


if __name__ == '__main__':
  driver = webdriver.Chrome()
  driver.maximize_window()
  driver.get('https://user.qunar.com/passport/login.jsp')
  driver.find_element_by_css_selector('a.pwd-login').click()
  aucthcode('//*[@id="captcha"][1]/p[1]')
  driver.quit()


  # img = Image.open('code.png')
  # imgcod = img.crop((1392,393,1490,425))     # 根据 div的长宽截图
  # imgcod.save('aucthcodeN.png')

注：代码中的验证码截取坐标，不一定是标准的，我是通过获取元素的坐标为基础参数，然后在main里面进行调试最终得到我适用的坐标
