+## 问题
+
+在JS逆向系列课的第3课《奇门遁甲 调用JavaScript执行代码》中，我们学到了多种在Python上调用JavaScript的方法。 那么现在，请运用你在第3课中学到的知识，尝试做一下这道题吧~
+你需要找出练习页中引入的含有getdata函数的JS文件，并尝试使用你在第3课中学习到的调用方法调用getdata函数。
+
+get_data执行结果的前16位字符是？
+
+1.打开浏览器开发者工具全局搜索 getdata，在console中打印 get_data() 返回
+
+![debugger](../img/94.png)
+
+2.将代码复制，node.js运行代码发现
+
+    if (screen['width'] || screen['height']) {
+        ^
+    
+    ReferenceError: screen is not defined
+
+3.控制台测试真实值
+    
+![debugger](../img/95.png)
+
+4.将js代码改成
+
+    if (1600 || 900) {
+        result = _0x49dc93['ObbQh'](___get_data);
+    }
+    
+输出

+## 问题
+
+在JS逆向系列课的第6课《初窥⻔径 阻挠爬⾍⼯程师的⽆限 debugger》中，我们学会了如何处理无限 debugger。 那么这是一道综合题，在过掉无限 debugger 后找出关键加密逻辑，并模拟。请运用你所学到的或是积累的知识，尝试做一下这道题吧~ 提示：注意Cookie
+
+如果关键参数 arg1 为 5D6DBFF4776ED19E013868C0663AC4A6FD3C2FEB，那么 set 的关键 cookie arg2 是多少？
