+## 逆向目标
+
+- 目标：网洛者反反爬虫练习平台第一题：JS 混淆加密，反 Hook 操作
+- 链接：http://spider.wangluozhe.com/challenge/1
+- 简介：本题要提交的答案是100页的所有数据并加和，要求以 Hook 的方式完成此题，不要以 AST、扣代码等方式解决，不要使用 JS 反混淆工具进行解密。（Hook 代码的写法和用法，K哥以前文章有，本文不再详细介绍）
+

+
+## 绕过无限 debugger
+
+首先观察到点击翻页，URL 并没有发生变化，那么一般就是 Ajax 请求，每一次请求有些参数会改变，熟练的按下 F12 准备查找加密参数，会发现立马断住，进入无限 debugger 状态，往上跟一个栈，可以发现 debugger 字样，如下图所示：
+
+![02.png](https://i.loli.net/2021/12/01/gxGapwsETNykFjm.png)
+
+这种情况在K哥以前的案例中也有，当时我们是直接重写这个 JS，把 debugger 字样给替换掉就行了，但是本题很显然是希望我们以 Hook 的方法来过掉无限 debugger，除了 debugger 以外，我们注意到前面还有个 constructor 字样，在 JavaScript 中它叫构造方法，一般在对象创建或者实例化时候被调用，它的基本语法是：`constructor([arguments]) { ... }`，详细介绍可参考 [MDN 构造方法](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Classes/constructor)，在本案例中，很明显 debugger 就是 constructor 的 arguments 参数，因此我们可以写出以下 Hook 代码来过掉无限 debugger：
+
+```javascript
+// 先保留原 constructor
+Function.prototype.constructor_ = Function.prototype.constructor;
+Function.prototype.constructor = function (a) {
+    // 如果参数为 debugger，就返回空方法
+    if(a == "debugger") {
+        return function (){};
+    }
+    // 如果参数不为 debugger，还是返回原方法
+    return Function.prototype.constructor_(a);
+};
+```
+
+注入 Hook 代码的方法也有很多，比如直接在浏览器开发者工具控制台输入代码（刷新网页会失效）、Fiddler 插件注入、油猴插件注入、自写浏览器插件注入等，这些方法在K哥以前的文章都有介绍，今天就不再赘述。
+
+本次我们使用 Fiddler 插件注入，注入以上 Hook 代码后，会发现会再次进入无限 debugger，setInterval，很明显的定时器，他有两个必须的参数，第一个是要执行的方法，第二个是时间参数，即周期性调用方法的时间间隔，以毫秒为单位，详细介绍可参考[菜鸟教程 Window setInterval()](https://www.runoob.com/jsref/met-win-setinterval.html)，同样我们也可以将其 Hook 掉：
+
+```javascript
+// 先保留原定时器
+var setInterval_ = setInterval
+setInterval = function (func, time){
+    // 如果时间参数为 0x7d0，就返回空方法
+    // 当然也可以不判断，直接返回空，有很多种写法
+    if(time == 0x7d0)
+    {
+        return function () {};
+    }
+    // 如果时间参数不为 0x7d0，还是返回原方法
+    return setInterval_(func, time)
+}
+```
+
+![03.png](https://i.loli.net/2021/12/01/wMTA1ltFDzmCRs6.png)
+
+将两段 Hook 代码粘贴到浏览器插件里，开启 Hook，重新刷新页面就会发现已经过掉了无限 debugger。
+
+![04.png](https://i.loli.net/2021/12/01/WAIrKJZkFX9iufH.png)
+
+## Hook 参数
+
+过掉无限 debugger 后，我们随便点击一页，抓包可以看到是个 POST 请求，Form Data 里，`page` 是页数，`count` 是每一页数据量，`_signature` 是我们要逆向的参数，如下图所示：
+
+![05.png](https://i.loli.net/2021/12/02/AfWqUbjB3HaxDke.png)
+
+我们直接搜索 `_signature`，只有一个结果，其中有个 `window.get_sign()` 方法就是设置 `_signature` 的函数，如下图所示：
+
+![06.png](https://i.loli.net/2021/12/02/Nx8O6tTSAP13b4j.png)
+
+这里问题来了！！！我们再看看本题的题目，JS 混淆加密，反 Hook 操作，作者也再三强调本题是考验 Hook 能力！并且到目前为止，我们好像还没有遇到什么反 Hook 手段，所以，这样直接搜索 `_signature` 很显然太简单了，肯定是要通过 Hook 的方式来获取 `_signature`，并且后续的 Hook 操作肯定不会一帆风顺！
+
+话不多说，我们直接写一个 Hook `window._signature` 的代码，如下所示：
+
+```javascript
+(function() {
+    //严谨模式 检查所有错误
+    'use strict';
+    //window 为要 hook 的对象，这里是 hook 的 _signature
+	var _signatureTemp = "";
+    Object.defineProperty(window, '_signature', {
+		//hook set 方法也就是赋值的方法 
+		set: function(val) {
+				console.log('Hook 捕获到 _signature 设置->', val);
+                debugger;
+				_signatureTemp = val;
+				return val;
+		},
+		//hook get 方法也就是取值的方法 
+		get: function()
+		{
+			return _signatureTemp;
+		}
+    });
+})();
+```
+
+将两个绕过无限 debugger 的 Hook 代码，和这个 Hook `_signature` 的代码一起，使用 Fiddler 插件一同注入（这里注意要把绕过 debugger 的代码放在 Hook `_signature` 代码的后面，否则有可能不起作用，这可能是插件的 BUG），重新刷新网页，可以发现前端的一排页面的按钮不见了，打开开发者工具，可以看到右上角提示有两个错误，点击可跳转到出错的代码，在控制台也可以看到报错信息，如下图所示：
+
+![07.png](https://i.loli.net/2021/12/02/WoSVFgNBajHek2O.png)
+
+整个 1.js 代码是经过了 sojson jsjiami v6 版本混淆了的，我们将里面的一些混淆代码在控制台输出一下，然后手动还原一下这段代码，有两个变量 `i1I1i1li` 和 `illllli1`，看起来费劲，直接用 `a` 和 `b` 代替，如下所示：
+
+```javascript
+(function() {
+    'use strict';
+    var a = '';
+    Object["defineProperty"](window, "_signature", {
+        set: function(b) {
+            a = b;
+            return b;
+        },
+        get: function() {
+            return a;
+        }
+    });
+}());
+```
+
+是不是很熟悉？有 get 和 set 方法，这不就是在进行 Hook `window._signature` 操作吗？整个逻辑就是当 set 方法设置 `_signature` 时，将其赋值给 a，get 方法获取 `_signature` 时，返回 a，这么操作一番，实际上对于 `_signature` 没有任何影响，那这段代码存在的意义是啥？为什么我们添加了自己的 Hook 代码就会报错？
+
+来看看报错信息：`Uncaught TypeError: Cannot redefine property: _signature`，不能重新定义 `_signature`？我们的 Hook 代码在页面一加载就运行了 `Object.defineProperty(window, '_signature', {})`，等到网站的 JS 再次 `defineProperty` 时就会报错，那很简单嘛，既然不让重新定义，而且网站自己的 JS Hook 代码不会影响 `_signature`，直接将其删掉不就行了嘛！这个地方大概就是反 Hook 操作了。
+
+保存原 1.js 到本地，删除其 Hook 代码，使用 Fiddler 的 AutoResponder 功能替换响应（替换方法有很多，K哥以前的文章同样有介绍），再次刷新发现异常解除，并且成功 Hook 到了  `_signature`。
+
+![08.png](https://i.loli.net/2021/12/02/3kLVGwhfDlCsWNx.png)
+
+![09.png](https://i.loli.net/2021/12/02/7c5HC4yiuFVKo8k.png)
+
+## 逆向参数
+
+成功 Hook 之后，直接跟栈，直接把方法暴露出来了：`window._signature = window.byted_acrawler(window.sign())`
+
+![10.png](https://i.loli.net/2021/12/02/gzuJKOiXAa3UIZc.png)
+
+先来看看 `window.sign()`，选中它其实就可以看到是 13 位毫秒级时间戳，我们跟进 1.js 去看看他的实现代码：
+
+![11.png](https://i.loli.net/2021/12/03/aWsj2qfVY8Lyw5N.png)
+
+我们将部分混淆代码手动还原一下：
+
+```javascript
+window["sign"] = function sign() {
+    try {
+        div = document["createElement"];
+        return Date["parse"](new Date())["toString"]();
+    } catch (IIl1lI1i) {
+        return "123456789abcdefghigklmnopqrstuvwxyz";
+    }
+}
+```
+
+这里就要注意了，有个坑给我们埋下了，如果直接略过，觉得就一个时间戳没啥好看的，那你就大错特错了！注意这是一个 try-catch 语句，其中有一句 `div = document["createElement"];`，有一个 HTML DOM Document 对象，创建了 div 标签，这段代码如果放到浏览器执行，没有任何问题，直接走 try 语句，返回时间戳，如果在我们本地 node 执行，就会捕获到 `document is not defined`，然后走 catch 语句，返回的是那一串数字加字母，最后的结果肯定是不正确的！
+
+解决方法也很简单，在本地代码里，要么去掉 try-catch 语句，直接 return 时间戳，要么在开头定义一下 document，再或者直接注释掉创建 div 标签的这行代码，但是K哥在这里推荐直接定义一下 document，因为谁能保证在其他地方也有类似的坑呢？万一隐藏得很深，没发现，岂不是白费力气了？
+
+然后再来看看  `window.byted_acrawler()`，return 语句里主要用到了 `sign()` 也就是 `window.sign()` 方法和 `IIl1llI1()` 方法，我们跟进  `IIl1llI1()` 方法可以看到同样使用了 try-catch 语句，`nav = navigator[liIIIi11('2b')];` 和前面 div 的情况如出一辙，同样的这里也建议直接定义一下 navigator，如下图所示：
+
+![14.png](https://s2.loli.net/2021/12/08/dGmLCQTBH2lptR1.png)
+
+![15.png](https://s2.loli.net/2021/12/08/V7sJdKFfuIY5o1r.png)
+
+到这里用到的方法基本上分析完毕，我们将 window、document、navigator 都定义一下后，本地运行一下，会提示 `window[liIIIi11(...)] is not a function`：
+
+![16.png](https://s2.loli.net/2021/12/08/g7MUING2Ft4LbWw.png)
+
+我们去网页里看看，会发现这个方法其实就是一个定时器，没有太大作用，直接注释掉即可：
+
+![17.png](https://s2.loli.net/2021/12/08/wV1XADy4jqoQEYW.png)
+
+## PyCharm 本地联调
+
+经过以上操作以后，再次本地运行，会提示 `window.signs is not a function`，出错的地方是一个 eval 语句，我们去浏览器看一下这个 eval 语句，发现明明是 `window.sign()`，为什么本地就变成了 `window.signs()`，平白无故多了个 s 呢？
+
+![18.png](https://s2.loli.net/2021/12/08/3NFwIuhpQTzAXDf.png)
+
+![19.png](https://s2.loli.net/2021/12/08/WoswIX96gvRLTle.png)
+
+造成这种情况的原因只有一个，那就是本地与浏览器的环境差异，混淆的代码里肯定有环境检测，如果不是浏览器环境的话，就会修改 eval 里的代码，多加了一个 s，这里如果你直接删掉包含 eval 语句的整个函数和上面的 setInterval 定时器，代码也能正常运行，但是，K哥一向是追求细节的！多加个 s 的原因咱必须得搞清楚呀！
+
+我们在本地使用 PyCharm 进行调试，看看到底是哪里给加了个 s，出错的地方是这个 eval 语句，我们点击这一行，下个断点，右键 debug 运行，进入调试界面（PS：原代码有无限 debugger，如果不做处理，PyCharm 里调试同样也会进入无限 debugger，可以直接把前面的 Hook 代码加到本地代码前面，也可以直接删除对应的函数或变量）：
+
+![20.png](https://s2.loli.net/2021/12/08/vAKwDeXM4m5cqRo.png)
+
+左侧是调用栈，右侧是变量值，整体上和 Chrome 里面的开发者工具差不多，详细用法可参考 [JetBrains 官方文档](https://www.jetbrains.com/help/pycharm/debugging-code.html)，主要介绍一下图中的 8 个按钮：
+
+1. Show Execution Point (Alt + F10)：如果你的光标在其它行或其它页面，点击这个按钮可跳转到当前断点所在的行；
+2. Step Over (F8)：步过，一行一行地往下走，如果这一行上有方法也不会进入方法；
+3. Step Into (F7)：步入，如果当前行有方法，可以进入方法内部，一般用于进入用户编写的自定义方法内，不会进入官方类库的方法；
+4. Force Step Into (Alt + Shift + F7)：强制步入，能进入任何方法，查看底层源码的时候可以用这个进入官方类库的方法；
+5. Step Out (Shift + F8)：步出，从步入的方法内退出到方法调用处，此时方法已执行完毕，只是还没有完成赋值；
+6. Restart Frame：放弃当前断点，重新执行断点；
+7. Run to Cursor (Alt + F9)：运行到光标处，代码会运行至光标行，不需要打断点；
+8. Evaluate Expression (Alt + F8)：计算表达式，可以直接运行表达式，不需要在命令行输入。
+
+我们点击步入按钮（Step Into），会进入到 `function IIlIliii()`，这里同样使用了 try-catch 语句，继续下一步，会发现捕获到了异常，提示 `Cannot read property 'location' of undefined`，如下图所示：
+
+![21.png](https://s2.loli.net/2021/12/08/KWtGkZw5Us9lARY.png)
+
+我们输出一下各个变量的值，手动还原一下代码，如下：
+
+```javascript
+function IIlIliii(II1, iIIiIIi1) {
+    try {
+        href = window["document"]["location"]["href"];
+        check_screen = screen["availHeight"];
+        window["code"] = "gnature = window.byted_acrawler(window.sign())";
+        return '';
+    } catch (I1IiI1il) {
+        window["code"] = "gnature = window.byted_acrawlers(window.signs())";
+        return '';
+    }
+}
+```
+
+这么一来，就发现了端倪，在本地我们并没有 document、location、href、availHeight 对象，所以就会走 catch 语句，变成了 `window.signs()`，就会报错，这里解决方法也很简单，可以直接删掉多余代码，直接定义为不带 s 的那串语句，或者也可以选择补一下环境，在浏览器里看一下 href 和 screen 的值，定义一下即可：
+
+```javascript
+var window = {
+    "document": {
+        "location": {
+            "href": "http://spider.wangluozhe.com/challenge/1"
+        }
+    },
+}
+
+var screen = {
+    "availHeight": 1040
+}
+```
+
+然后再次运行，又会提示 `sign is not defined`，这里的 `sign()` 其实就是 `window.sign()`，也就是下面的 `window[liIIIi11('a')]` 方法，任意改一种写法即可：
+
+![22.png](https://s2.loli.net/2021/12/08/xSQL7FrsMtyUGk3.png)
+
+再次运行，没有错误了，我们可以自己写一个方法来获取 `_signature`：以下写法二选一，都可以：
+
+```javascript
+function getSign(){
+    return window[liIIIi11('9')](window[liIIIi11('a')]())
+}
+
+function getSign(){
+    return window.byted_acrawler(window.sign())
+}
+
+// 测试输出
+console.log(getSign())
+```
+
+我们运行一下，发现在 Pycharm 里并没有任何输出，同样的我们在题目页面的控制台输出一下 `console.log`，发现被置空了，如下图所示：
+
+![23.png](https://s2.loli.net/2021/12/08/5X1BwyqvfoR7l6h.png)
+
+看来他还对  `console.log` 做了处理，其实这种情况问题不大，我们直接使用 Python 脚本来调用前面我们写的 `getSign()` 方法就能得到 `_signature` 的值了，但是，再次重申，K哥一向是追求细节的！我就得找到处理 `console.log` 的地方，把它变为正常！
+
+这里我们仍然使用 Pycharm 来调试，进一步熟悉本地联调，在 `console.log(getSign())` 语句处下个断点，一步一步跟进，会发现进到了语句 `var IlII1li1 = function() {};`，查看此时变量值，发现 `console.log`、`console.warn` 等方法都被置空了，如下图所示：
+
+![24.png](https://s2.loli.net/2021/12/08/w6q3A5xDypVWSzG.png)
+
+再往下一步跟进，发现直接返回了，这里有可能第一次运行 JS 时就会对 console 相关命令进行方法置空处理，所以先在疑似对 console 处理的方法里面下几个断点，再重新调试，会发现会走到 else 语句，然后直接将 IlII1li1 也就是空方法，赋值给 console 相关命令，如下图所示：
+
+![25.png](https://s2.loli.net/2021/12/08/grjXMAowxzYWEmD.png)
+
+定位到了问题所在，我们直接把 if-else 语句注释掉，不让它置空即可，然后再次调试，发现就可以直接输出结果了：
+
+![26.png](https://s2.loli.net/2021/12/08/AUV6kgurWdC1Thz.png)
+
+调用 Python 携带 _signature 挨个计算每一页的数据，最终提交成功：
