使用base64对vue传递的参数进行加密，springboot解密

废话少说，直接上代码
vue终端执行

npm install --save js-base64

然后在使用的时候

let Base64 = require('js-base64').Base64//加密方法let oPassword =  Base64.encode(that.form.oldPassword);    let nPassword =  Base64.encode(that.form.newPassword);     //解密方法(此处我没有用到)    //let oPassword = Base64.decode(密文)

传输到后台之后，在后台创建Base64Utils工具类

使用方法如下

oldPassword = Base64Utils.decode(oldPassword);newPassword = Base64Utils.decode(newPassword);

如果有什么不对的地方，欢迎指出
