Javascript 和 我之前发的 python加密以及 go加密解密不一样 不需要导那么多的库只需要安装几个库 其中需要了解最多的 crypto-js
具体就不多介绍了直接上官网https://www.npmjs.com/package/crypto-js
安装
npm install crypto-js --save-devnpm install md5 --save-devunescape() 函数可对通过 escape() 编码的字符串进行解码。
let e = escape("始識")console.log(e) // %u59CB%u8B58let u = unescape(e)console.log(u) // 始識let e = encodeURI("https://始識的博客")console.log(e) // https://%E5%A7%8B%E8%AD%98%E7%9A%84%E5%8D%9A%E5%AE%A2let u = decodeURI(e)console.log(u) // https://始識的博客将 Unicode 编码转为一个字符
