对于常见滑动极验模块的破解

一滑动验证码破解原理

这里使用到了selenium+opencv的知识点

废话不多说放源码

import time
from selenium import webdriver

from slideVerfication import SlideVerificationCode

# 一、打开浏览器，访问QQ空间登录页面
driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(5)
driver.get('https://qzone.qq.com/')

# 二、点击账号密码登录
# 2，1切换到登录的iframe中
driver.switch_to.frame('login_frame')
# 2.2 点击
driver.find_element_by_xpath("//a[@id='switcher_plogin']").click()

# 三、输入账号密码，点击登录按钮
# 3.1 定位账号输入框，输入账号
driver.find_element_by_xpath('//*[@id="u"]').send_keys('6787878887')
# 3.2 定位密码输入框，输入密码
driver.find_element_by_xpath('//*[@id="p"]').send_keys('lemonban')
# 3.3 点击登录按钮
driver.find_element_by_xpath('//*[@id="login_button"]').click()

# 四、滑动验证码破解
# 4.1切换到滑动验证码的iframe中
driver.switch_to.frame(driver.find_element_by_id('tcaptcha_iframe'))
# 4.2获取滑块元素
block_ele = driver.find_element_by_id('slideBlock')
# 4.3获取背景图元素
slideBg = driver.find_element_by_id('slideBg')
# 4.4 识别滑动距离
sli = SlideVerificationCode()

dis = sli.get_element_slide_distance(block_ele, slideBg)
# 4.5对滑动的距离进行等比缩放
dis = dis * (280 / 680) - 31
print("滑动的距离", dis)
# 4.6 滑动验证
btn = driver.find_element_by_id('tcaptcha_drag_thumb')
sli.slide_verification(driver, btn, dis)
driver.find_element_by_id('tcaptcha_drag_thumb')
# 5秒之后关闭浏览器
time.sleep(5)
driver.quit()

对于不能直接获得背景图，需要使用js的方法来获取对应的图片

def save_img(img_name,class_name):
    # img_name 是保存图片的名字，class_name 是需要保存的canvas的className
    getImgJS = 'return document.getElementsByClassName("'+ class_name +'")[0].toDataURL("image/png");'
    img =driver.execute_script(getImgJS)
    base64_data_img = img[img.find(',') + 1:]
    image_base = base64.b64decode(base64_data_img)
    file = open(img_name, 'wb')
    file.write(image_base)
    file.close()
这样只需要将背景图和小图的class——name 放进去就好了

save_img('full.jpg', 'geetest_canvas_bg')
save_img('cut.jpg', 'geetest_canvas_slice')

二 文字点选的破解该如何
这边直接使用了腾讯云ocr识别（但是有误差）

import json
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException
from tencentcloud.ocr.v20181119 import ocr_client, models
try:
    cred = credential.Credential("AKIDUlmX1EApENGsEI5bqpY0B5i48wTHp78s", "UhdJipfEWXHkxua08zZtxlHXWEZicHgo")
    httpProfile = HttpProfile()
    httpProfile.endpoint = "ocr.tencentcloudapi.com"

    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = ocr_client.OcrClient(cred, "ap-beijing", clientProfile)

    req = models.GeneralBasicOCRRequest()
    params = {
        "ImageUrl": "https://static.geetest.com/nerualpic/word_l1_zh_2021.01.21/abstract/42685f1aec6060cd1a09c084d6776476.jpg?challenge=3726c01d0b6fb4c85bc8004d06568f67"
    }
    req.from_json_string(json.dumps(params))

    resp = client.GeneralBasicOCR(req)
    print(resp.to_json_string())

except TencentCloudSDKException as err:
     print(err)
这里只需要传入文字图片地址就好了
获取文字点选图片的方法

# strhtml = driver.execute_script("return document.documentElement.innerHTML")
# soup = BeautifulSoup(strhtml, 'lxml')
# data = soup.select('body > div.geetest_panel.geetest_wind > div.geetest_panel_box.geetest_no_logo.geetest_panelshowclick > div.geetest_panel_next > div > div > div.geetest_table_box > div.geetest_window > div > div.geetest_item_wrap > img')
# s=str(data[0])
# res = re.findall(r'src="([^"]+)"',s)
# print(res[0])
