如何使用CryptoJS AES两次使用AES加密

Question

我尝试使用cryptojs加密两次，但没有任何回报，这就是我的代码

var defaultKey = "Part of the journy is the end. Whatever it takes";
var userKey = 'in this whole universe iron man is the best superhero';
var encryptMsg ='';

encryptMsg = CryptoJS.AES.encrypt(msg, defaultKey);
alert(encryptMsg);
encryptMsg = CryptoJS.AES.encrypt(encryptMsg , userKey );
alert(encryptMsg);

第一个警报显示加密的文本，但seconf警报不显示任何内容

我找到了解决方案，我不知道这是正确的方法，但是这件事对我有用

var defaultKey = "Part of the journy is the end. Whatever it takes";
var userKey = 'in this whole universe iron man is the best superhero';
var encryptMsg ='';

encryptMsg = CryptoJS.AES.encrypt(msg, defaultKey);
alert(encryptMsg);
encryptMsg = CryptoJS.AES.encrypt(String(encryptMsg) , userKey );
alert(encryptMsg);

我使用String（）
