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）
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 = de('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 www.chaojiying/price.html
"""
params = {
'codetype': codetype,
}
params.update(self.base_params)
files = {'userfile': ('ccc.jpg', im)}
r = requests.post('upload.chaojiying/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('upload.chaojiying/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 = '/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 = (url=url,headers=headers).text
tree = etree.HTML(page_text)
try:
code_img_src = tree.xpath('//*[@id="verifyPic_login"]/@src')[0]
code_img_data = (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)

def login_url():
login_url = '/ajaxLogin/login?1=1&uniqueTimestamp=2021212242112'    data = {

response = requests.post(url=login_url,headers=headers,data=data)
print(response.status_code)
login_page_text =

fp.write(login_page_text)
kies
def Profile():
pro_url = '/969120248/profile'
pr_respose_text = (url=pro_url,headers=headers,cookies=login_url()).text

}
response = session.post(url=login_url,headers=headers,data=data)
print(response.status_code)
login_page_text =
with open('renren.html','w',encoding='utf-8') as fp:
fp.write(login_page_text)
kies
def Profile_Se():
pro_url = '/969120248/profile'
pr_respose_text = (url=pro_url,headers=headers,cookies=login_url_Se()).text    with open('profile_New.html','w',encoding='utf-8') as fp:
fp.write(pr_respose_text)
