TYC自动登录

某查公司网站登录解密（极验滑动验证码思路）

模拟登录某查获取登录用户名以及登录cookie，供后续使用

提示：以下是本篇文章正文内容，下面案例可供参考

一、geetest

import time
import requests
import re
url = 'https://www.tianyancha.com/verify/geetest.xhtml' # 天眼查极验接口 获取gt与challenge用
data = {"uuid": int(time.time() * 1000)}
res = requests.post(url, json=data).json()
req = res
gt, challenge = req['data']["gt"], req['data']["challenge"]
get_token_headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.193 Safari/537.36'}
api = 'https://api.geetest.com/get.php?gt={}' \
'&challenge={}&product=popup&offline=false' \
'&protocol=https://&path=/static/js/geetest.6.0.9.js&pencil=/static/js/pencil.1.0.3.js' \
'&voice=/static/js/voice.1.2.0.js&type=slide&beeline=/static/js/beeline.1.0.1.js' \
'&maze=/static/js/maze.1.0.1.js&callback=geetest_{}'.format(gt, challenge, int(time.time() * 1000))
res = requests.get(api, headers=get_token_headers)
img_json = re.findall("\((.*)\)", res.text, re.S)[0]
# 获取验证码图片 及缺口地址的json

图片复原，缺口识别

拿到的图片为乱序图片，复原并进行缺口识别
复原后的图片

识别出缺口位置并模拟生成滑动轨迹坐标
[[-34, -32, 0], [0, 0, 0], [7, -1, 157], [12, -1, 173], [20, -1, 191], [30, -1, 208], [40, -1, 227], [48, -1, 242], [55, -1, 260], [59, -1, 278], [62, -1, 297], [65, -1, 314], [67, -1, 333], [68, -1, 352], [68, -1, 370], [72, -1, 388], [71, -1, 404], [71, -1, 423], [73, -1, 441], [74, -1, 459], [72, -1, 476], [73, -1, 493], [73, -1, 511], [75, 0, 526], [75, 0, 542], [75, 0, 559], [74, 0, 578], [74, 0, 593], [75, 0, 611], [76, 0, 629], [77, 1, 646], [75, 1, 664], [74, 1, 680], [75, 1, 696], [76, 1, 713], [76, 1, 728], [75, 1, 747], [75, 1, 763], [77, 1, 782], [76, 1, 798], [77, 1, 815], [75, 1, 832], [76, 1, 849], [78, 1, 868], [77, 1, 888], [75, 1, 908], [75, 1, 927], [75, 1, 944], [76, 1, 960], [76, 1, 976], [76, 1, 996], [76, 1, 1012], [76, 1, 1032], [76, 1, 1254]]

通过坐标经过极验js转换为字符串

经过加密生成核心w参数

代码如下（示例）：

至此 极验的主要登录参数就全部构造出来

请求成功之后会返回一个validate参数
用此参数可以成功登录某查并拿到登录后的cookie
