對抗：cookie反爬蟲處理，關鍵字v，如圖
解決步驟
1、JS中關鍵字查找
如上，我們找到了關鍵字 v，那么接下來就用hook搜查
點擊F12，打開 開發者工具，選擇Console直接輸入hook代碼
(function () {Object.defineProperty(document, 'cookie', {set: function (val) {if (val.indexOf('v') != -1) {debugger;}console.log('Hook捕獲到cookie設置->', val);return val;}});
})();# val.indexOf('v') 中輸入你要的關鍵字，回車
# 注意需要等待一會，因為程序加載需要時間
# 回車后，程序執行到v處自動斷點，并打印，可一步步向下看js推理
運行后如圖，n產出剛好是v的數值
接著點擊右上角的箭頭，會一步步執行接下來的js
連續點一遍下來發現n值最后由 function D() 產出
全局搜索 function D()，最后輸出在這，后面可以創建個空值去接收
2. JS調試技巧
從這里可以發現就是整個的文件只有千多行代碼，可以采用全復制方式處理cookie
2.1、扣出所有代碼，放入自建js文件中，我這例如: cookie.js
2.2、利用execjs執行
import execjswith open('qq.js', encoding='utf-8') as f:x = f.read()v = execjs.compile(x).call('get_cookie')
print(v)
這時會報錯一堆錯，而且還要挨個補環境，例如下：
execjs._exceptions.ProgramError: ReferenceError: document is not defined
execjs._exceptions.ProgramError: ReferenceError: window is not defined
execjs._exceptions.ProgramError: ReferenceError: navigator is not defined
這時可以使用 jsdom 這個技術，在 js 文件最上方加入運行js所缺補的環境，例如下（所有通用）
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);window = dom.window
document = window.document
navigator = window.navigator
官方文檔：https://github.com/jsdom/jsdom/wiki/jsdom
然后python代碼需要調用其中的函數，獲取到產出的v值
1、在 js上面創建 ==》 var _v = {};
2、在 function D() 后面加入.xialuo 接收 ==》 _v.xialuo = D， 如圖
3、末尾創建個函數好被python調用
function getCookie() {return _v.xialuo()
}
最后，cookie.js 代碼如下：
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);
window=dom.window;
document=window.document;
navigator=window.navigator;var _v = {}var TOKEN_SERVER_TIME = 1656072000.984;
