```console
$ npx rs-reverse makecode -h
rs-reverse makecode
rs-reverse makecode
生成动态代码
接收ts.json文件生成immucfg、ts、ts-full文件，如果传入的是url则还会生成html、主代
码、动态代码文件，还可通过-j命令接收多个$_ts.l__处理的文件url并生成该js文件及解
密后的js文件。
**`-j`参数需要注意，链接地址必须带上查询参数，不带的话返回的是未经过瑞数处理的文件，可以从浏览器控制台查看带参数的完整地址，如果待解密的js文件存在多个时，为了保证结果中变量名与瑞数解析的变量名一致，需要按浏览器的解析顺序依序传入（因为变量名存在复用逻辑）。**
Options:
-h 显示帮助信息 [boolean]
-f, --file 含有nsd, cd值的json文件 [string]
-l, --level 日志打印等级，参考log4js，默认为info [string]
-u, --url 瑞数返回204状态码的请求地址 [string]
-v, --version 显示版本号 [boolean]
Examples:
rs-reverse makecode -f example/codes/1-$_ts.json
rs-reverse makecode -u http://url/path
-a, --adapt 已经做了适配的网站名称，不传则为cnipa [string]
-j, --jsurls $_ts.__l方法执行的js文件链接(必须带上查询参数)，多个时需要按顺
序传入，如：-j "https://host/chunk.js?4VGu1xaT=a728b2" -j
"https://host/app.js?4VGu1xaT=a728b2" [array]
-v, --version 显示版本号
```
调用示例：
```bash
$ npx rs-reverse makecode -u https://wcjs.sbj.cnipa.gov.cn/sgtmi
$ npx rs-reverse makecode -u https://wcjs.sbj.cnipa.gov.cn/sgtmi -j 'https://wcjs.sbj.cnipa.gov.cn/js/chunk-vendors.66e24864.js?查询参数' -j 'https://wcjs.sbj.cnipa.gov.cn/js/app.9f7a91c9.js?查询参数'
