网页内容为动态执行js所得

1、直接浏览器模拟

不用考虑页面的业务逻辑什么的,直接得到结果。

这个就不做过多分析了。

直接取就好。

 

2、js解析,动态执行execjs

import re
import execjs
import requests

 

a、每个文章对应的js内容都不一样,并且混淆js代码;导致分析起来难度增加。

b、分析得到js逻辑后,执行eval代码错误,兼容性处理(windows、document根本没有)

 1 _0x3fd7 = ['split', 'fromcharcode', 'fqzuq', 'xznnm', 'undefined', 'qhdvc', 'yfzjd', 'stylesheets', 'addrule', '.context_kw', 'content:\x20\x22', '::before{content:\x20\x22', 'pad', 'zeropadding', 'clamp', 'sigbytes', 'words', 'nhezs', 'ybdyq', 'trpqn', 'aixex', 'prototype', 'uzvib', 'wu0l5htlyctrnwrzi8ph1amdqdew5nwdygjang7ckfvp24hy4pgf10n2dutttdcvgrjf4kbf8xhqtnzs46detaeq9m/+k43adrzl8akkiso9gwq+yezamy4p+hwdk4c0cuer2afwkzujesnswnw8fu7idewugjmzns0s2ejcwraqy0yikozo3sm3me9npmh4z/v9xcaz7cbpd/wh//tmfq==', 'latin1', 'd8215dba71e02e3a', 'window', 'location', 'href', 'enc', 'parse', '84219dd60f203784', '146385f634c9cb00', 'aes', 'tostring', 'createelement', 'style', 'setattribute', 'type', 'async', 'link', 'getelementsbytagname', 'usvog', 'onotz', 'length', 'parentnode', 'insertbefore', 'head', '4|5|1|2|3|0'];
 2 
 3 cnt = 0x163
 4 while cnt > 0:
 5     _0x3fd7.append(_0x3fd7.pop(0))
 6     cnt = cnt - 1
 7 print(_0x3fd7)
 8 
 9 with open('content.js', 'r') as f:
10     text = f.read()
11     for i, item in enumerate(_0x3fd7):
12         text = text.replace("_0x73fd('" + str(hex(i)) + "')", "'" + eval('_0x3fd7[' + str(i) + ']') + "'")
13 
14 with open('content.dec.js', 'w') as f:
15     f.write(text)

 

c、所以要对js代码进行一次清洗。

js = clear_js(js)

 

d、得到解密结果,整理正文输出

node = execjs.compile(js)
words = node.eval('words')

 

爬取动态html网页,requests+execjs
