下载账单API
为交易账单和资金账单封装了一个接口，把申请和下载合为一步，并且提供了验证摘要的方法。

以下是示例，开发指引文档会在文档中心提供

BillDownloadServiceExtension service =
    new BillDownloadServiceExtension.Builder().config(config).build();
GetTradeBillRequest request = new GetTradeBillRequest();
request.setBillDate("2023-07-23");
request.setBillType(BillType.ALL);
request.setTarType(TarType.GZIP);
DigestBillEntity bill = service.getTradeBill(request);

try (InputStream inputStream = bill.getInputStream()) {
  try (BufferedOutputStream outputStream =
      new BufferedOutputStream(new PrintStream(System.out))) {
    byte[] buffer = new byte[16384];
    int bytesRead;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
      outputStream.write(buffer, 0, bytesRead);
    }
  }
}

if (bill.verifyHash()) throw new RuntimeException();
