python爬虫 - js逆向解密之简单端口加密破解v2 - 修复版

前言

这篇跟上一篇很像，而且他的端口显示也很类似，是的，它也是一个国外的代理网站

分析

打开网站查看：

python爬虫 - js逆向解密之简单端口加密破解v2 -- 修复版

发现它的的端口和之前的网站一样，不是直接显示的，那么用SmallProxy这个关键词搜索下在哪，很快就找到了下面这个：

关键点

代码：

<script type="text/javascript">
//<![CDATA[
  Xinemara = 2051;BigBlind = Xinemara^42776;DexterProxy = Xinemara^19605;BigGoodProxy = 26194^DexterProxy;Defender = 18662^BigGoodProxy;SmallProxy = 32206^BigGoodProxy;SmallBlind = 24500^Defender;Agile = Defender^BigGoodProxy;ProxyMoxy = 31100^Agile;BigProxy = 35563^SmallProxy;DontGrubMe = BigProxy^BigProxy;NineBeforeZero = 40710^14588;Xorg = SmallProxy^57660;Socks = 61653^27735;HttpSocks = BigBlind^DexterProxy;GrubMe = 1176^45424;Polymorth = 23590^54130;
//]]>
</script>

代码实现

好的，废话不多说了，主要用了exec和eval，直接给代码了，因为之前一篇文章分析过了，就不再详细说了

import requests
from lxml import etree
from lxml.html import tostring
from bs4 import BeautifulSoup, Comment

HEADERS = {
    'sec-ch-ua': '"Google Chrome";v="89", "Chromium";v="89", ";Not A Brand";v="99"',

}

url = ''  # 保密

req = requests.get(url, headers=HEADERS)
res = req.content.decode('utf-8')
html = etree.HTML(res)
end = []
data = html.xpath('//table[@class="proxytbl"]/tr[position()>1]')
key = html.xpath('//noscript/preceding-sibling::script[1]/text()')
key = ''.join(key).replace('//<![CDATA[','').replace('//]]>','').strip() if key else ''
exec(key.strip())
for item in data:
    ip = item.xpath('./td[1]/text()')
    ip = ''.join(ip) if ip else ''
    port_temp = item.xpath('./td[2]/script/text()')
    port_temp = ''.join(port_temp) if port_temp else ''
    port_temp = port_temp.replace('document.write(', '').replace(');', '').replace('//<![CDATA[','').replace('//]]>','').strip()
    port = eval(port_temp)
    print(12313213,ip,port)
    # if ip and port:
    #     proxy = ip + ":" + port
    #     end.append(proxy)
print(12312, len(end), end)
