1.超级鹰注册

超级鹰: https://www.chaojiying.com/
注册后购买题分

2.获取要识别的图片

我们以这个附件下载的网页为例: https://gh.lnut.edu.cn/system/_content/download.jsp?urltype=news.DownloadAttachUrl&owner=1224556702&wbfileid=1504223
点开f12然后刷新几次验证吗找到接口

验证码图片接口链接: https://gh.lnut.edu.cn/system/resource/js/filedownload/createimage.jsp
每次访问都会刷新出新的图片

import requests
img_url='https://www.jsei.edu.cn/system/resource/js/filedownload/createimage.jsp'
img_res=requests.get(img_url,verify=False)

3.使用超级鹰识别验证码

首先需要将超级鹰的文档保存

#!/usr/bin/env python
# coding:utf-8import requests
from hashlib import md5class Chaojiying_Client(object):def __init__(self, username, password, soft_id):self.username = usernamepassword =  password.encode('utf8')self.password = md5(password).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/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)',}def PostPic(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 PostPic_base64(self, base64_str, codetype):"""im: 图片字节codetype: 题目类型 参考 http://www.chaojiying.com/price.html"""params = {'codetype': codetype,'file_base64':base64_str}params.update(self.base_params)r = requests.post('http://upload.chaojiying.net/Upload/Processing.php', data=params, headers=self.headers)return r.json()def ReportError(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()

使用超级鹰

import requests
from chaojiying import *
import requests
img_url='https://gh.lnut.edu.cn/system/resource/js/filedownload/createimage.jsp'
img_res=requests.get(img_url,verify=False)
chaojiying = Chaojiying_Client('账号', '密码', '软件ID')	#用户中心>>软件ID 生成一个替换 96001												#本地图片文件路径 来替换 a.jpg 有时WIN系统须要//
yzmcode=chaojiying.PostPic(img_res.content, 1902)["pic_str"]
print(yzmcode)
