js hook

1. jquery hook 这是我的油猴插件

   (function() {
       'use strict';
       //console.log("hook my xhr")
       !function(t){function r(n){if(e[n])return e[n].exports;var o=e[n]={exports:{},id:n,loaded:!1};return t[n].call(o.exports,o,o.exports,r),o.loaded=!0,o.exports}var e={};return r.m=t,r.c=e,r.p="",r(0)}([function(t,r,e){e(1)(window)},function(t,r){t.exports=function(t){t.hookAjax=function(t){function r(r){return function(){var e=this.hasOwnProperty(r+"_")?this[r+"_"]:this.xhr[r],n=(t[r]||{}).getter;return n&&n(e,this)||e}}function e(r){return function(e){var n=this.xhr,o=this,i=t[r];if("function"==typeof i)n[r]=function(){t[r](o)||e.apply(n,arguments)};else{var a=(i||{}).setter;e=a&&a(e,o)||e;try{n[r]=e}catch(t){this[r+"_"]=e}}}}function n(r){return function(){var e=[].slice.call(arguments);if(!t[r]||!t[r].call(this,e,this.xhr))return this.xhr[r].apply(this.xhr,e)}}window._ahrealxhr=window._ahrealxhr||XMLHttpRequest,XMLHttpRequest=function(){var t=new window._ahrealxhr;Object.defineProperty(this,"xhr",{value:t})};var o=window._ahrealxhr.prototype;for(var i in o){var a="";try{a=typeof o[i]}catch(t){}"function"===a?XMLHttpRequest.prototype[i]=n(i):Object.defineProperty(XMLHttpRequest.prototype,i,{get:r(i),set:e(i),enumerable:!0})}return window._ahrealxhr},t.unHookAjax=function(){window._ahrealxhr&&(XMLHttpRequest=window._ahrealxhr),window._ahrealxhr=void 0},t.default=t}}]);
       //js加载完成执行
       //console.log(hookAjax)
       hookAjax({
           //拦截回调
           onreadystatechange:function(xhr){
               console.log("onreadystatechange called: %O",xhr)
           },
           onload:function(xhr){
               console.log("onload called: %O",xhr)
           },
           //拦截方法
           open:function(arg,xhr){
               console.log("open called: method:%s,url:%s,async:%s",arg[0],arg[1],arg[2])
           },
           setRequestHeader:function(arg,xhr){
               console.log("setRequestHeader called: method:%s,name:%s,value:%s",arg[0],arg[1],arg[2])
           }
       })
       console.log("hook xhr")
       // Your code here...
   })();

2. hook window 函数

   orig = window.eval;
   window.eval=function(str){debugger;orig(str);}
   // 这段代码防止反hook的检测
   window.eval.toString = function (){return orig.toString();}

3. hook 节点

   var dom_get_element = document.getElementById;
   document.getElementById = function(id){if(id=="9DhefwqGPrzGxEp9hPaoag") debugger; dom_get_element(id);}
