python爬虫-国家企业_国家企业信用公示系统的爬取

python爬⾍-国家企业_国家企业信⽤公⽰系统的爬取

具体操作：

response = (kie_url)

js_code1 =

print(js_code1)

kies)

输出

对这段代码进⾏js反混淆，得到

var x =

"toLowerCase@@@@267@@@@window@36@@@@firstChild@div@@catch@@var@rOm9XFMtA3QKV7nYsPGT4lifyWwkq5vcjH2I "").split("@"),

y = "j 3=34(){2r('y.30=y.1e+y.2f.33(/[\\?|&]32-2a/,\\'\\')',1a);3c.10='2l=1p.5|1b|'+(34(){j 3=2m(+[[[-~{}+(+!-[])+(+!-[])]*(-~

{}+(+!-[])+(+!-[]))]]),1g=['%',[[(+!-[])+(+!-[])]/~~''+[[]][1b]][1b].22(24),'3n%2q',[{}+[]+[]][1b].22(-~~~''-~[-~~~''+(-~~~''<

f = function(x, y) {

var a = 0,

b = 0,

c = 0;

x = x.split("");

y = y || 99;

while ((a = x.shift()) && (b = a.charCodeAt(0) - 77.5)) c = (Math.abs(b) < 13 ? (b + 48.5) : parseInt(a,

36)) + y * c;

return c

z = f(y.match(/\w/g).sort(function(x, y) {

return f(x) - f(y)

}).pop());

while (z++) try {冰棍机

place(/\b\w+\b/g, function(y) {

return x[f(y, z) - 1] || ("_" + y)

}));

break

} catch (_) {}

对js代码进⾏格式化处理，再调⽤python的execjs执⾏这段代码，如下所⽰：

js_code1 = js_code1.rstrip('\n')

js_code1 = place('', '')

js_code1 = place('

index = js_code1.rfind('}')

js_code1 = js_code1[0:index + 1]

js_code1 = 'function getCookie() {' + js_code1 + '}'压片机模具

js_code1 = place('eval', 'return')

js_code2 = execjspile(js_code1)

code = js_code2.call('getCookie')

print(code)

得到结果为：

var _1l=function(){setTimeout('location.href=location.pathname+place(/[\?|&]captcha-

challenge/,\'\')',1500);kie='__jsl_clearance=1553940235.414|0|'+(function(){var _1l=Array(+[[-~!{}]+[-~! {}]]),_O=['URpBd',(((+!-[])+[(+!-[])+(+!-[])]>>(+!-[])+(+!-[]))+[[]][0]),'BM',(((+!-[])+[(+!-[])+(+!-[])]>>(+!-[])+(+!-[]))+[[]][0])+[{}+ []+[[]][0]][0].charAt(-~{}),'GQ7RqBB',(!+[]+[]+[[]][0]).charAt(~~'')+[[(+!-[])+(+!-[])]/~~''+[]][0].charAt((-~~~''<<-~~~'')+([(+!-[])+ (+!-[])]+~~!{}>>(+!-[])+(+!-[]))),'LMV',({}+[]).charAt([-~!{}]+(~~''+[[]][0])),'BUc%',(!{}+[]+[[]][0]).charAt(-~!{})+[{}+[]+[[]][0]] [0].charAt(-~{}),'D'];for(var _7=0;_7<_O.length;_7++){_1l.reverse()[_7]=_O[_7]};return _1l.join('')})()+';Expires=Sat, 30-Mar-19 11:03:55 GMT;Path=/;'};if((function(){try{return !!window.addEventListener;}catch(e){return false;}})())

{document.addEventListener('DOMContentLoaded',_1l,false)}else{document.attachEvent('onreadystatechange',_1l)}

同样进⾏js反混淆，得到

var _1l = function () {

setTimeout('location.href=location.pathname+place(/[\?|&]captcha-challenge/,\'\')', 1500);

按摩锤kie = '__jsl_clearance=1553940235.414|0|' + (function () {

var _1l = Array(+[

[-~!{}] + [-~!{}]

]),

_O = ['URpBd', (((+!-[]) + [(+!-[]) + (+!-[])] >> (+!-[]) + (+!-[])) + [

[]

][0]), 'BM', (((+!-[]) + [(+!-[]) + (+!-[])] >> (+!-[]) + (+!-[])) + [

][0]).charAt(~~'') + [

[(+!-[]) + (+!-[])] / ~~'' + []

][0].charAt((-~~~'' << -~~~'') + ([(+!-[]) + (+!-[])] + ~~!{} >> (+!-[]) + (+!-[]))), 'LMV', ({} + []).charAt([-~!{}] + (~~'' + [

[]

for (var _7 = 0; _7 < _O.length; _7++) {

_1l.reverse()[_7] = _O[_7]

};

return _1l.join('')

})() + ';Expires=Sat, 30-Mar-19 11:03:55 GMT;Path=/;'

};

if ((function () {

try {

return !!window.addEventListener;

} catch (e) {

return false;

}

})()) {

document.addEventListener('DOMContentLoaded', _1l, false)

} else {

document.attachEvent('onreadystatechange', _1l)

}

同样对这段js代码格式化，再⽤python的execjs进⾏调⽤，得到结果

code = 'var a' + code.split('kie')[1].split("Path=/;'")[0] + "Path=/;';return a;" code = 'window = {}; \n' + code

js_final = "function getClearance(){" + code + "};"

ctx = execjspile(js_final)

jsl_clearance = ctx.call('getClearance')

jsl_cle = jsl_clearance.split(';')[0].split('=')[1]

print('__jsl_clearance=' + jsl_cle)

得到最终⽣成的cookie

__jsl_clearance=1553940235.414|0|URpBdaoBMjGQ7RqBBtyLMV3oBUc%3D

与第⼀次请求得到的cookie ⼀起发送给服务器，就能返回正常结果。
