爬虫--实现图片验证码全自动输入
爬取网站：豆瓣（/login）
爬虫思路：1. 使用selenium, 对图片验证码进行截图操作，
2. 接入打码平台--云打码，传输图片，返回验证码
一. 爬虫代码如下：
import timefrom selenium import webdriverfrom PIL import Imagefrom io import BytesIO # 以IO的形式转换为二进制import YDM_testclass DouBan(object):def __init__(self):self.url = '/login'self.headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'}def run(self):# 创建chrome对象, 发送get请求chrome = webdriver.Chrome('/home/python/Desktop/chromedriver')chrome.get(self.url)# 获取输入框元素, 输入账号密码time.sleep(1)chrome.find_element_by_id('email').send_keys('your_count@')chrome.find_element_by_id('password').send_keys('your_pwd')# 截图打码 --> 重点screen_shot = chrome.get_screenshot_as_png()# 获取全屏截图的对象screen_image = Image.open(BytesIO(screen_shot)) # 以IO的形式转换为二进制screen_image.save('00_screen_image.png')# 对验证码图片区域进行截图，保存code_image_el = chrome.find_element_by_id('captcha_image') # 获取验证码图片对象height = code_image_el.size['height']width = code_image_el.size['width']left = code_image_el.location['x']top = code_image_el.location['y']right = left + widthbottom = top + height# 验证码图片--区域位置信息cut_info = (left, top, right, bottom)print(cut_info)# 截图操作,保存截图cut_image = screen_image.crop(cut_info)cut_image.save('00_cut_image.png')# 全自动打码--云打码平台code = YDM_test.image_decode('00_cut_image.png')chrome.find_element_by_id('captcha_field').send_keys(code)# 点击登陆chrome.find_element_by_name('login').click()# 退出浏览器time.sleep(3)chrome.quit()if __name__ == '__main__':db = DouBan()db.run()
二. 云打码SDK接口文件 --> YDM_test.py
