1安装

javascript">npm i jsencrypt

2.rsa.js

javascript">/* 产引入jsencrypt实现数据RSA加密 */
import JSEncrypt from 'jsencrypt' // 处理长文本数据时报错 jsencrypt.js Message too long for RSA

export {encryptCode,decryptCode，encrypt,decrypt
}

3.在页面使用

javascript"><script setup>
import { ref, getCurrentInstance, rective} from "vue";
import { encryptCode,decryptCode,encrypt,decrypt} from "@/utils/rsa"
const info = ref({
username:"name",
password:"123456"
})
let logins = {username: info.value.username,password: info.value.password,};let login1 = that.$utils.encryptCode(JSON.stringify(logins)); //加密let login = that.$utils.decryptCode(login1); //解密// 如果解密字段过长，返回null，用encryptlong进行解密let login = that.$utils.decrypt(login1); //解密
//接口
</script
