HarmonyOS crypto-js加密没有返回值

可参考如下代码：

function desEncrypt(message: string, key: string): string{
  try {
    const keyHex: string = CryptoJS.enc.Base64.parse(key);
    console.log("=====>keyHex", keyHex);
    const encrypted: string = CryptoJS.TripleDES.encrypt(message, keyHex, {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7
    }).toString();
    console.log("=====>encrypted", encrypted);
  } catch (e) {
    console.log(JSON.stringify(e))
  }
  return "null";
}
aboutToAppear(): void {
  desEncrypt("http://123?a=1", "密钥")
}
