The following demo is an interception of the verification code from the official website of Qunar

from selenium import webdriver
from PIL import Image

def aucthcode(coderddr):"""
 Xpath to pass parameter verification code
 The full picture of the page is'code.png'Just name this and you are happy
 The verification code screenshot is named"aucthcode.png
 : param coderddr::return:"""
  
 driver.save_screenshot('code.png')
 element = driver.find_element_by_xpath(coderddr)    #Get the div position of the verification code
 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))     #Screenshot according to the length and width of the div
 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))     #Screenshot according to the length and width of the div
 # imgcod.save('aucthcodeN.png')

Note: The interception coordinates of the verification code in the code are not necessarily standard. I get the coordinates of the elements as the basic parameters, and then debug in the main to finally get the coordinates I apply

Run effect display code.png

Run the intercepted verification code effect display aucthcode.png
