需要登陆，Form data

找到_csrf和password，_csrf，在登陆页面

找加密password的js代码，ctrl+F搜索password，重新填入input

找到加密函数KeyEncrypt

找到JSEncrypt，CryptoJs

执行

用execjs执行js或者用js2py

node.js或Jscript报navigator is not define，可以用PhantomJS

#运行时环境设置
import execjs
import execjs.runtime_names
os.environ["EXECJS_RUNTIME"] = "PhantomJS"
PhantomJS = execjs.get(execjs.runtime_names.PhantomJS)
print(execjs.get().name)

结果如图

pytohn执行

是混淆的js

抓包

有二条请求

第一条加cookie，第二条正常，需要知道怎么加的cookie

代码执行一下或者找工具解密

(function anonymous() {
    if (window.wp1) {
        document.cookie = 'OPEN_E4C0C08491=' + wp3;
        document.cookie = 'OPEN_ID=B32pJOwfO/AJZJ3ZGmnunQNTaUie84jnyHoNCq/onZQ='
    }
}
)

加cookie的部分

js：

var wp1 = 'xKIOt5jUZQcS8wurcX4lghwlET9K0IWBUsS3ZqmSamCBTAPg7Fl5sVr443dyK42p';
var wp2 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
var wp3 = "548545fe3ced4f3494934e537e304705";
var wp4 = "464acf618bf62df3e7e37e80c2c1a04d";
var wp5 = "0aa9566c4aa30883e34d0e1a530bf508";
var wp6 = "a8f49232d343e4b94ff7958088fa6734";
var wp7 = "82f778b45a9fce8589105c852174947b";
var wp8 = "3221d819c9b96d2631d0b5084c736f69";
if (window.wp1) {
        document.cookie = 'OPEN_E4C0C08491=' + wp3;
        document.cookie = 'OPEN_ID=B32pJOwfO/AJZJ3ZGmnunQNTaUie84jnyHoNCq/onZQ='
    }

var getGlobal = function() {
        if (typeof self !== '') {
            return self
        }
        ;if (typeof window !== '') {
            return window
        }
        ;if (typeof global !== '') {
            return global
        }
        ;throw new Error('unable to locate global object')
    };
function _process(s) {
        var result = s.substring(5, 7).concat('s').concat(s.substring(14, 15)).concat('v').concat(s.substring(9, 13)).concat('g').concat(s.substring(5)).concat('l').concat(s.substring(11, 19));
        return result.substr(0, 32);
    }
    ;var _switch = false;
    if ((getGlobal() === window)) {
        _switch = true
    } else {
        _switch = false
    };
document.cookie = 'SIGNIN_ID=3e2291010f36c9244c633aba4cdcdd42';
document.cookie = 'SIGNIN_UC=9e65d8fc646e49fb7a0f9f8237915bfb';
document.cookie = 'UNDEFINED=432e9111ecf89746f3046ca970814f41';
if (_switch) {
        document.cookie = 'OPEN_589D5869B5=' + _process(wp3);
        setTimeout("location.reload();", 100);
}

。。。很多参数不知道哪里来的搞不定了，用selenium

#配置chorme
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(chrome_options=chrome_options,executable_path = 'D:\python\chromedriver.exe')
from time import sleep

#登陆
driver.get("http://openlaw.cn/login.jsp?logout") 
driver.find_element_by_id("username").send_keys("XXXXXXXXX")
driver.find_element_by_id("password").send_keys("XXXXXXXXX")
sleep(2)
driver.find_element_by_id("submit").click()

#页面数据
driver.get("http://openlaw.cn/guidance/167ce490ba94c3ed26baab5689fdd620") 
sleep(2)
title=driver.find_element_by_xpath('//h1[@class="entry-title"]').text
guid=driver.find_element_by_xpath('//div[@class="annotator-wrapper"]/p').text
content=driver.find_element_by_xpath('//div[@class="annotator-wrapper"]/p[2]').text
page_detail={"title":title,"content":guid+"\n"+content.replace("\u3000"," ")}

结果
