JsHook

<<<<<<< HEAD

设计理念：

• 让JSHOOK更方便。

目标：

• Hook function
• Hook 参数
• 直接Hook对象，比如直接Hook WebSocket对象

例子：

• 引用了JsHook.js文件后，初始化JsHook只需下面的代码：

var myalert1= new JsHook;

• Hook函数可参考下面的例子：

(function  () {
 "use strict";
 if (typeof JsHook == "undefined"){
     //先判断JsHook是否定义
     console.log("JsHook类没有定义！");
     return 0;
 }
 var myalert1= new JsHook;
 myalert1.initHook(window,"alert",function (msg) {
     console.log("我是myalert1,alert已经被HooK，消息是："+msg);
     myalert1.CallOrigin("这是myalert1放行的数据!");
     return 0;
 });
 var myalert2= new JsHook;
 myalert2.initHook(window,"alert",function (msg) {
     console.log("我是myalert2，alert已经被HooK，消息是："+msg);
     myalert2.CallOrigin("我是myalert2!");
     return 0;
 });
 alert("测试2层Hook");
 console.log("2层Hook测试完毕，下面测试Hook的暂停。");
 myalert2.SuspendedHook();
 alert("测试SuspendedHook");
 myalert2.RestoreHook();
 console.log("2层Hook测试完毕，下面测试Hook的恢复。");
 alert("测试RestoreHook");
 //请按顺序
 myalert2.DeleteHook();
 myalert1.DeleteHook();
 console.log("Hook测试完毕。");
 alert("Hook测试完毕。")
})();

• Hook某个参数可参考代码：

window.a=1024;
(function () {
    "use strict";
    if (typeof JsHook == "undefined"){
        //先判断JsHook是否定义
        console.log("JsHook类没有定义！");
        return 0;
    }
    var dealfunction = (...p_list)=>{
        console.log(`${ p_list[0] }.${ p_list[1] }的数据被设置，数据是：${ p_list[2] }`)
        return 100;
    }
    var mywindow = new JsHook;
    mywindow.initHook(window,"a",dealfunction);
    console.log("下面尝试Hook数据修改！")
    window.a=1024;
    console.log(window.a);
    mywindow.DeleteHook();
    console.log("下面尝试删除Hook！")
    window.a=1024;
    console.log(window.a);
})();
