抖音推广运营/太原seo哪家好
在本篇博客中，我们将使用selenium模拟登录新浪微博，破解其登陆时的图片验证码。微博和简书、b站登录有所不同，后两个每次登录都会有验证码，微博有时有有时可能没有，所以写法稍有不同。
我们需要使用验证码识别服务平台。超级鹰，来帮助我们破解图片验证码。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 = usernameself.password = md5(password.encode('utf-8')).hexdigest()self.soft_id = soft_idself.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()
