项目思路解析

请求目标网页地址 从静态网页中提取出ip地址（端口图片暂时不做处理）

通过xpath的方式提取出对应的网页数据 提取下来的数据是进行加密的

提取数据的代码

session = requests.session()

url = ‘https://www.zdaye.com/FreeIPList.html’

response = session.get(url, headers=headers)

data = response.content.decode()

html_object = etree.HTML(data)

data_list = html_object.xpath(‘//*[@id=“ipc”]/tbody/tr’)

​

ip_list = []

for tr in data_list:

ipnum = tr.xpath(‘./td[1]/text()’)[0]

ipnum2 = tr.xpath(‘./td[1]/@v’)[0]

ip_list.append((ipnum, ipnum2))

找到数据的加密方法 查看是否为动态加载的数据

并不是动态数据 找到加密的js文件

打断点调试js代码

解析对应的加密函数

​

def sdfsgfdg(s):

s2 = s.split(‘m’)

ts = ‘’

for i in range(len(s2) - 1, -1, -1):

ts += chr(int(s2[i]) - 352)

return ts

​

​

def MD5§:

return hashlib.md5(§.encode()).hexdigest().upper()

​

​

def get_keyurl(mk, ak):

url = ‘https://www.zdaye.com/’ + mk + “_” + MD5(MD5(sdfsgfdg(mk) + “beiji” + ak)) + ‘.gif’

return url

​

​

def dsfgsd(s, kk):

s2 = s.split(‘#’)

ts = ‘’

for i in range(len(s2) - 1, -1, -1):

ts += chr(int(s2[i]) - kk)

​

return ts

​

​

t = str(time.strftime(‘%Y/%m/%d %H:%M:%S’,time.localtime())).replace(’ ', “%20”).replace(“/0”, “/”)

new_url = ‘https://www.zdaye.com/js/base.js?’ + t

pp = session.get(new_url, headers=headers)

mk = re.findall(‘mk = “(.*?)”;’, pp.text)[0]

ak = re.findall(‘ak = “(.*?)”;’, pp.text)[0]

key_url = get_keyurl(mk, ak)

key = session.get(key_url, headers=headers)

out函数从html页面获取到td的v标签数据进行解析 showm为MD5的加密方法
