Python+Request库+第三方平台实现验证码识别示例

1、登录时经常的出现验证码，此次结合Python+Request+第三方验证码识别平台（超级鹰识别平台）

2、首先到超级鹰平台下载对应语言的识别码封装，超级鹰平台：http://www.chaojiying.com/price.html

3、使用超级鹰平台需进行注册，购买1元，应该有1000次积分，再生产对应软件ID

4、超级鹰下载Python语言进行Demo示例，代码如下（命名为ClassCode.py）：

import requests
from hashlib import md5

class Chaojiying_Client(object):

    def __init__(self, username, password, soft_id):
        self.username = username
        password = password.encode('utf8')
        self.password = md5(password).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/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 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()

5、下面使用ClassCode.py模块中的代码，对人人网实现验证码登录，此时示例分别使用Cookie和Session进行演示

import requests
from .ClassCode import Chaojiying_Client （导入ClassCode.py 模块）
from lxml import etree  （需安装：pip3 install lxml）

# 对验证码图片进行抓捕及识别
url = 'http://www.renren.com/SysHome.do'

headers = {
    "User-Agent":"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
}
page_text = requests.get(url=url,headers=headers).text
tree = etree.HTML(page_text)
try:
    code_img_src = tree.xpath('//*[@id="verifyPic_login"]/@src')[0]
    code_img_data = requests.get(url=code_img_src, headers=headers).content
    with open('./code_img_data.jpg', 'wb') as fp:
        fp.write(code_img_data)
except Exception as msg:
    print('元素不存在')

# 使用超级鹰平台实现验证码识别
chaojiying = Chaojiying_Client('超级鹰登录账号', '超级鹰登录密码', '根据验证码类型')
with open('code_img_data.jpg', 'rb') as fp:
     img = fp.read()
result = chaojiying.PostPic(img, 1005)['pic_str']
print(result)

    data = {
