详解基于python如何实现破解滑动验证码

 import time
 from selenium import webdriver
 from slideVerfication import SlideVerificationCode
 ​
 # 1、创建一个driver对象，访问qq登录页面
 browser = webdriver.Chrome()
 browser.get("https://qzone.qq.com/")
 ​
 # 2、输入账号密码
 # 2.0 点击切换到登录的iframe
 browser.switch_to.frame('login_frame')
 # 2.1 点击账号密码登录
 browser.find_element_by_id('switcher_plogin').click()
 # 2.2定位账号输入框，输入账号
 browser.find_element_by_id("u").send_keys("123292678")
 # 2.3定位密码输入输入密码
 browser.find_element_by_id("p").send_keys("PYTHON01")
 # 3、点击登录
 browser.find_element_by_id('login_button').click()
 time.sleep(3)
 ​
 # 4、模拟滑动验证
 # 4.1切换到滑动验证码的iframe中
 tcaptcha = browser.find_element_by_id("tcaptcha_iframe")
 browser.switch_to.frame(tcaptcha)
 # 4.2 获取滑动相关的元素
 # 选择拖动滑块的节点
 slide_element = browser.find_element_by_id('tcaptcha_drag_thumb')
 # 获取滑块图片的节点
 slideBlock_ele = browser.find_element_by_id('slideBlock')
 # 获取缺口背景图片节点
 slideBg = browser.find_element_by_id('slideBg')
 # 4.3计算滑动距离
 sc = SlideVerificationCode(save_image=True)
 distance = sc.get_element_slide_distance(slideBlock_ele,slideBg)
 # 滑动距离误差校正，滑动距离*图片在网页上显示的缩放比-滑块相对的初始位置
 distance = distance*(280/680) - 22
 print("校正后的滑动距离",distance)
 # 4.4、进行滑动
 sc.slide_verification(browser,slide_element,distance=100)
