实现简单的模拟登录网站

Posted 2021-12-12 wen-kang

本次登录站点为古诗文网

URL：https://so.gushiwen.org/user/login.aspx?from=http://so.gushiwen.org/user/collect.aspx

对于验证码的解析：采用云打码API接口实现 http://www.yundama.com

主页面实现代码：

import requests
requests.packages.urllib3.disable_warnings()        #禁用证书安装警告
from lxml import etree
from verify import getCodeDate

#获取网站的登录页面链接
url=‘https://so.gushiwen.org/user/login.aspx?from=http://so.gushiwen.org/user/collect.aspx‘

S=requests.Session()
user_agent={"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/72.0.3626.109 Safari/537.36"}

page_text=requests.get(url=url,headers=user_agent,verify=False).text    #登录页面文本内容
tree=etree.HTML(page_text)
i_url=tree.xpath(‘//img[@id="imgCode"]/@src‘)[0]            #解析出验证码的url
code_img_url="https://so.gushiwen.org"+i_url                #拼接完整验证码完整的URI

#通过session去访问验证码url请求  为避免HTTPS中的ssl验证关闭验证
img_data=S.get(url=code_img_url,headers=user_agent,verify=False).content

with open(‘./code/code.jpg‘,‘wb‘)as f:
    f.write(img_data)               #验证码本地持久化存储
f.close()

#调用云打码API去解析验证码文本内容
code_text=getCodeDate(‘bobo328410948‘,‘bobo328410948‘,‘./code/code.jpg‘,1004)
print(code_text)

login_url=‘https://so.gushiwen.org/user/login.aspx?from=http%3a%2f%2fso.gushiwen.org%2fuser%2fcollect.aspx‘
data={
    "__VIEWSTATE":"pnxXA5gIeJn+zyAzqHvjCGecHVkhFmDqa2YvRtvdp/9Yexq5Mngv8LjGEY4AmtwlXa36vUe0p4FxAvwDWIwYSiwv4g/7+oomRXa4hlKrhenT/ydAGJAQBzbXVbQ=",
    "__VIEWSTATEGENERATOR":"C93BE1AE",
    "from":"http://so.gushiwen.org/user/collect.aspx",
    "email":"[e-mail]",
    "pwd":"1159402553",
    "code":code_text,
    "denglu":"登录",
}
user_page=S.post(url=login_url,data=data,headers=user_agent).text
print(user_page)
with open(‘./gushi.html‘,‘w‘,encoding=‘utf-8‘)as f:
    f.write(user_page)

云打码的API接口代码：

对云打码API接口封装的函数代码：

from ydm import YDMHttp

def getCodeDate(userName,pwd,codePath,codeType):
    # 用户名(普通用户)
    username    = userName

    # 密码
    password    = pwd

    # 软件ＩＤ，开发者分成必要参数。登录开发者后台【我的软件】获得！
    appid       = 6003

    # 软件密钥，开发者分成必要参数。登录开发者后台【我的软件】获得！
    appkey      = ‘1f4b564483ae5c907a1d34f8e2f2776c‘

    # 图片文件
    filename    = codePath

    # 验证码类型，# 例：1004表示4位字母数字，不同类型收费不同。请准确填写，否则影响识别率。在此查询所有类型 http://www.yundama.com/price.html
    codetype    = codeType

    # 超时时间，秒
    timeout     = 20
    result = None
    # 检查
    if (username == ‘username‘):
        print(‘请设置好相关参数再测试‘)
    else:
        # 初始化
        yundama = YDMHttp(username, password, appid, appkey)

        # 登陆云打码
        uid = yundama.login()
        #print(‘uid: %s‘ % uid)

        # 查询余额
        balance = yundama.balance()
        #print(‘balance: %s‘ % balance)

        # 开始识别，图片路径，验证码类型ID，超时时间（秒），识别结果
        cid, result = yundama.decode(filename, codetype, timeout)
        #print(‘cid: %s, result: %s‘ % (cid, result))
    return result
