JSEncrypt 库 ：

- 引入了 jsencrypt/bin/jsencrypt.min
- 需要在项目中安装 jsencrypt 包

npm install jsencrypt

import JSEncrypt from 'jsencrypt/bin/jsencrypt.min'// 密钥对生成 http://web.chacuo.net/netrsakeypairconst publicKey = 'MFwAAQ=='const privateKey = 'MIIBVAIBADANBgkqhkiG9w0BAQEFAASCAT4wggE6AgEAAkEAqhHyZfSsYourNxaY\n' +'7Nt+PrgrxkiA50efORdI5U5lY='// 加密
export function encrypt(txt) {const encryptor = new JSEncrypt()encryptor.setPublicKey(publicKey) // 设置公钥return encryptor.encrypt(txt) // 对数据进行加密
}// 解密
export function decrypt(txt) {const encryptor = new JSEncrypt()encryptor.setPrivateKey(privateKey) // 设置私钥return encryptor.decrypt(txt) // 对数据进行解密
}

 这个页面是根据路由转的，再url的参数上把他们合为一个json对象再加密

 

 点击的页面根据路由监听获取数据，先解密再解析json对象

 

 因为这里有一个二维码功能，二维码的网址对应也需要加密，所以后端也需要加密，后端也使用的

RSA加密，配置公钥为前端的公钥进行加密
