处理很囧的 javascript 页面

比如  http://dasai.56star.cn/Template/dasai/VoteAdd.js

  
   eval(function(p, a, c, k, e, d) { e = function(c) { return (c < a ? "" : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36)) }; if (!''.replace(/^/, String)) { while (c--) d[e(c)] = k[c] || e(c); k = [function(e) { return d[e] } ]; e = function() { return '\\w+' }; c = 1; }; while (c--) if (k[c]) p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]); return p; } ('8 B(o,0){$(".v"+0).u("t","");$.4("/n/9.a?b=D&d="+j.l(),{m:"4",A:\'d\'},8(2,f){5(2.7=="i"){x(0,2.h)}6{3("w，r(k)。");q p}},"s")}8 x(0,g){$.4("/n/9.a?b=C&d="+j.l(),{m:"4",E:0,h:g},8(2,f){5(2.7=="i"){3("Q，O。");N c=M($(".y"+0).e());$(".y"+0).e((c+1))}6 5(2.7=="H"){3("G(F)I，L。")}6 5(2.7=="z"){3("z，K。"+2.J)}6{3("w，r。");q p}},"s");$(".v"+0).u("t","P")}', 53, 53, 'nVoteID||data|alert|post|if|else|state|function|Vote|aspx|action|nCount||html|textStatus|szKey|key|success|Math||random|Action|Ajax||false|return|请稍后尝试|json|display|css|VoteLoading|系统忙|VoteAddDB|VoteCount|fraud|szName|MyVoteAdd|VoteToToToTo|GetKey|nVoteFK|他|您已经给她|repeat|投过票了|text|请再偿试|您还可以支持其它人|parseInt|var|谢谢您|none|投票成功'.split('|'), 0, {}))
  
 

  
   这里使用 V8 引擎是最好的选择~ Chrome 核心~
  
 

  
   # easy_install pyv8
  
 

  
   
    In [17]: import PyV8

In [18]: context = PyV8.JSContext()

In [19]: context.enter()

In [20]: import urllib

In [21]: script = urllib.urlopen("http://dasai.56star.cn/Template/dasai/VoteAdd.js").read()

In [22]: context.eval(script)

In [23]: context.locals.keys()
Out[23]: ['MyVoteAdd', 'VoteAddDB']

~ got it.
   
  
 

  
   
    刚好用这搞定 qq 登录的加密~.
