## JS混淆
####加密数据是无法通过在后台找到接口进行请求来获取数据
###### 目标网站：https://www.endata.com.cn/BoxOffice/BO/Year/index.html
###### 1. html中无法找到正文数据

###### 2. 点击xhr中查看，发现有一组加密的接口和数据。

###### 3. 搜索JSON.parse发现多个接口JS文件，无法定位JS位置，再次将XHR中找到的接口进行搜索。

###### 4. 进入到JS源代码中，进行搜索JSON.parse，进行打断点。

###### 5. 刷新网站，将加密参数写入JS脚本。

js代码建议放到附件，云盘，或者github/gitee之类的仓库托管，丢个链接进来。

太长了不方便阅读，此外ob混淆的js不建议格式化，有可能有防止格式化的正则表达式会造成死循环。。。

似乎有两个图片的格式也存在问题~[]()后面的小括号似乎没了。。

看了看内容，顺便用易语言改写了下（依赖精易模块及E2EE支持库）

.版本 2
.支持库 e2ee
.支持库 spec

.子程序 __启动窗口_创建完毕
.局部变量加解密, 加解密对象
.局部变量 text, 文本型
.局部变量输出, 字节集
.局部变量 a1, 整数型
.局部变量 a2, 整数型
.局部变量 key, 文本型

text ＝ #常量2
a1 ＝进制_十六到十 (取文本中间 (text, 取文本长度 (text), 1)) ＋ 9
a2 ＝进制_十六到十 (取文本中间 (text, a1 ＋ 1, 1))
text ＝取文本左边 (text, a1) ＋取文本右边 (text, 取文本长度 (text) － a1 － 1)
key ＝取文本中间 (text, a2 ＋ 1, 8)
text ＝取文本左边 (text, a2) ＋取文本右边 (text, 取文本长度 (text) － a2 － 8)
加解密.解密数据 (#算法_DES_ECB, HEX解码 (text), key, 输出, #填充方式_PKCS7, , #文本内容类型_原始内容)
调试输出 (到文本 (文本编码转换 (输出, “UTF-8”, “GBK”)))
