安装依赖crypto-js

npm install crypto-js --save


import CryptoJS from &＃39;crypto-js&＃39;let keySizes,iterationCounts;
let AesUtil &＃61; function (keySize, iterationCount) {keySizes &＃61; keySize / 32;iterationCounts &＃61; iterationCount;

}
//let aes &＃61; new AesUtil(128,147);
// let decrypted &＃61; aes.decrypt("这里是SALT","这里是IV","这里是明文的固定KEY","要解密字符串");
// console.log(decrypted);
// let encrypted &＃61; aes.encrypt("这里是SALT","这里是IV","这里是明文的固定KEY","要加密字符串");
// console.log(encrypted);
export default {encrypt:that.encrypt,decrypt:that.decrypt,
}


导出来的对象里面encrypt和decrypt就是加密和解密函数
