解答思路

1. javascript代码格式为jsfuck编码
2. 运行代码得到1bc29b36f623ba82aaf6724fd3b16718.php，这时候会想到解码这个字符串，可能为16进制转换，也可能为md5加密，但这题在这里只是个陷阱
3. "在我脑袋里"的提示解密有点无厘头，这里的貌似只能靠联想
4. history of bash 需要想到.bash_history文件名

解题步骤

1. 在chrome console中运行上述代码，得到结果：

1bc29b36f623ba82aaf6724fd3b16718.php

1. 访问上述网址，得到结果：

哈哈哈哈哈哈你上当啦，这里什么都没有，TIP在我脑袋里

1. 根据"在我脑袋里"的提示，查看response中的header标签，看到一项非正常的返回头

tip: history of bash

1. 根据提示，访问.bash_history：

http://teamxlc.sinaapp.com/web3/b0b0ad119f425408fc3d45253137d33d/.bash_history

得到结果：

shell zip -r flagbak.zip ./*

1. 根据提示，访问：

http://teamxlc.sinaapp.com/web3/b0b0ad119f425408fc3d45253137d33d/flagbak.zip

下载解压flagbak.zip后得到flag
