Python爬虫--实现图片验证码全自动输入_自动填充图片验证码的代码

爬虫--实现图片验证码全自动输入

爬取网站：豆瓣（https://accounts.douban.com/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 time
from selenium import webdriver
 
from PIL import Image
from io import BytesIO    # 以IO的形式转换为二进制
 
import YDM_test
 
 
class DouBan(object):
    def __init__(self):
        self.url = 'https://accounts.douban.com/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@163.com')
        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 + width
        bottom = 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
