3.对12306进行模拟登录:验证码图片必须通过裁剪图片的形式获取

3.1.浏览器实例化 bro = webdriver.Chrome(executable_path='./chromedriver.exe') 

3.2.发起请求 bro.get('https://kyfw.12306.cn/otn/login/init') 

3.3.输入用户名和密码

3.4.标签定位验证图片 code_img_ele=bro.find_element_by_xpath('//*@id="loginForm"]/div/ul[2]/li[4]/div/div/div[3]/img') 

3.5.验证码  左上角坐标location location = code_img_ele.location 

3.6.验证码  长度size size = code_img_ele.size 

3.7.指定矩形区域

rangle=(int(location['x']),int(location['y']),int(location['x']+size['width']),int(location['y']+size['height']))

3.8.截图整张页面save_screenshot()

3.9.指定区域截图crop

3.10.调用超级鹰对验证码进行识别  

3.11.将x,y变成[[x,y]]

3.12.基于动作链,将x,y的参照系转移到指定的标签中  move_to_element_with_offse

3.13.点击登录
