直接上代码

一.前端

import CryptoJS from 'crypto-js';
	/**
 * 加密解密
 *`在这里插入代码片`
 * @type {string}
 */
// const key = '*1smurfs*';
const key = '1234567812345678';
const iv = '1234567812345678';
export function getKey() {
  // 真正的key
  return CryptoJS.enc.Utf8.parse(key);
}

export function getIv() {
  // 真正的iv
  return CryptoJS.enc.Utf8.parse(iv);
}
export function encrypt(data) {
  // console.log(getKey(key));
  // let encrypt = CryptoJS.AES.encrypt(data, CryptoJS.enc.Hex.parse(getKey(key)), {
  //   mode: CryptoJS.mode.ECB,
  //   padding: CryptoJS.pad.Pkcs7
  // })
  // const message = CryptoJS.enc.Utf8.parse(data);
  var ciphertext = CryptoJS.AES.encrypt(data, getKey(), {
    iv: getIv(),
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
  });
  return ciphertext.toString();
  // return CryptoJS.AES.encrypt(data, getKey(), { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }).toString();
}

export function decrypt(data) {
  var bytes = CryptoJS.AES.decrypt(data.toString(), getKey(), {
    iv: getIv(),
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
  });
  return bytes.toString(CryptoJS.enc.Utf8);
  // const decrypt = CryptoJS.AES.decrypt(data, getKey(key), {
  //   mode: CryptoJS.mode.ECB,
  //   padding: CryptoJS.pad.Pkcs7
  // });
  // return CryptoJS.enc.Utf8.stringify(decrypt).toString();
}

二.后端代码

        // 加密
        long lStart = System.currentTimeMillis();
        String enString = AESpkcs7paddingUtil.encrypt("Aes cbc 中文测试加标点符号！@#￥%……&*（+——）", key);
        System.out.println("加密后的字串是：" + enString);

        long lUseTime = System.currentTimeMillis() - lStart;
        System.out.println("加密耗时：" + lUseTime + "毫秒");

        // 解密
        lStart = System.currentTimeMillis();
        String DeString = AESpkcs7paddingUtil.decrypt(enString , key);
        System.out.println("解密后的字串是：" + DeString);
        lUseTime = System.currentTimeMillis() - lStart;
        System.out.println("解密耗时：" + lUseTime + "毫秒");
    }

}

以上是前后端加密的代码,测试OK!
