Python爬虫实战 | (16) 破解简书登录点触验证码
在本篇博客中，我们将使用selenium模拟登录简书网站，破解其登陆时的滑动验证码。
我们需要使用验证码识别服务平台。超级鹰，来帮助我们破解点触验证码。下面的chaojiying.py文件用于调用超级鹰服务，帮助我们破解点触或图片验证码，直接照搬就好了：
import requests
from hashlib import md5
#使用超级鹰来进行图片验证码和点触验证码的识别
class Chaojiying(object):
def __init__(self, username, password, soft_id):
self.username = username
self.password = md5(password.encode('utf-8')).hexdigest()
self.soft_id = soft_id
self.base_params = {
'user': self.username,
'pass2': self.password,
'softid': self.soft_id,
}
self.headers = {
'Connection': 'Keep-Alive',
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36',
}
def post_pic(self, im, codetype):
"""
im: 图片字节
codetype: 题目类型 参考 http://www.chaojiying.com/price.html
"""
params = {
'codetype': codetype,
}
params.update(self.base_params)
files = {'userfile': ('ccc.jpg', im)}
r = requests.post('http://upload.chaojiying.net/Upload/Processing.php', data=params, files=files,
headers=self.headers)
return r.json()
def report_error(self, im_id):
"""
im_id:报错题目的图片ID
"""
params = {
'id': im_id,
}
params.update(self.base_params)
r = requests.post('http://upload.chaojiying.net/Upload/ReportError.php', data=params, headers=self.headers)
return r.json()
