HarmonyOS 鸿蒙Next 证书解析

// 解析证书
certParseByBase64Str = (base64Str: string): ResolveResult => {
  let certData = '-----BEGIN CERTIFICATE-----\n' + base64Str + '\n-----END CERTIFICATE-----\n';
  Logger.info('certData=:', certData);

  let textEncoder = new util.TextEncoder();
  let encodingBlob: certFramework.EncodingBlob = {

    // 将证书数据从string类型转换成Unit8Array data: textEncoder.encodeInto(certData),

    // 证书格式，仅支持PEM和DER。在此示例中，证书为PEM格式

    encodingFormat: certFramework.EncodingFormat.FORMAT_PEM
  };

  let resultData: ESObject = {};

  let ret: ResolveResult = {}
  certFramework.createX509Cert(encodingBlob, (err, x509Cert) => {
    if (err != null) {
      Logger.info('err.message=:', JSON.stringify(err));

      // 创建X509Cert实例失败

      ret = {
        iSuccessful: false,
        errorMsg: "createX509Cert failed, errCode:${err.code}, errMsg:${err.message}",
        data: resultData
      };
      return ret;

    } else {

      try {

        let CN = x509Cert.getSubjectName();

        // 证书的序列号
        let serialNumner = x509Cert.getCertSerialNumber();

        // 证书有效期起始日期
        let notBeforeTime = x509Cert.getNotBeforeTime();

        // 证书有效期截止日期
        let notAfterTime = x509Cert.getNotAfterTime();
        Logger.info('serialNumner=:', serialNumner.toString());
        Logger.info('notBeforeTime=:', notBeforeTime);
        Logger.info('notAfterTime=:', notAfterTime);
        resultData = {
          serialNumner: serialNumner,
          notBeforeTime: notBeforeTime,
          notAfterTime: notAfterTime,
          CN: CN
        };

        Logger.info('resultData=:', JSON.stringify(resultData));
        ret = { iSuccessful: true, errorMsg: '', data: resultData };
        return ret;
      } catch (e) {
        ret = { iSuccessful: false, errorMsg: "解析异常" + e.message, data: resultData };
        return ret;
      }
    }
  })
}

写了一个证书解析的方法  解析后怎么返回返回出去？目前在createX509Cert这样写返回ResolveResult 报错。

还有一个疑问  

let CN = x509Cert.getSubjectName();

解析证书CN怎么获取？在官方文档上没有找到。
