java - 寻找一种从 cloudhopper smpp 服务器返回 DeliverSmResp 和错误代码的方法

Question

我正在寻找一种将 SMPP 错误代码从服务器发送到连接的客户端的方法。我的流程是:1.客户端发送短信到我的服务器2.我将其发送到另一个系统3.当我收到消息状态时(最多可能需要 72 小时)我想将结果发送回作为接收器连接的客户端。我还注意到，当我将其发送给客户时，我看到:

Default handling is to discard unexpected response PDU: (submit_sm_resp:

public void sendResponsePdu(String dlrId, String status) throws RecoverablePduException, SmppChannelException, UnrecoverablePduException, InterruptedException {
        PduResponse pdu = dlrs.remove(dlrId);
        if (pdu != null) {
            pdu.setResultMessage("0xa");
            sendResponsePdu(pdu);
        }
    }

我寻找一种在发生错误时在方法 sendResponsePdu 上返回 SMPP 错误代码的方法

我希望在客户端中看到错误代码 0xa这意味着“源地址无效”但像往常一样 ESME_ROK我从 C# 项目中获取了图像，我可以在其中看到响应的样子当从 SMSC 发送时

更新我使用下一个代码返回 DLR，但我找不到设置“err”、“stat”和 messageid 的方法 enter link description here

Answer 1

这是设置所有 DLR 字段并将其发送回客户端的解决方案

 byte[] textBytes = "-".getBytes();

        DeliverSm deliver = new DeliverSm();

        deliver.setSourceAddress(new Address((byte) 0x03, (byte) 0x00, pduResponseWrapper.getFromNumber()));
        deliver.setDestAddress(new Address((byte) 0x01, (byte) 0x01, pduResponseWrapper.getToNumber()));
        deliver.setShortMessage(textBytes);
        deliver.setDataCoding(pduResponseWrapper.getDataCoding());
        deliver.setSequenceNumber(pduResponseWrapper.getDeliverSm().getSequenceNumber());
        deliver.setEsmClass((byte) 0x04);
        deliver.setProtocolId((byte) 0x00);
        deliver.setPriority((byte) 0x00);
        deliver.setScheduleDeliveryTime(null);
        deliver.setValidityPeriod(null);
        deliver.setRegisteredDelivery((byte) 0x00);
        deliver.setReplaceIfPresent((byte) 0x00);
        deliver.setDefaultMsgId((byte) 0x00);

        DateTime submitDate = new DateTime();
        DateTime doneDate = new DateTime();
        byte state=SmppConstants.STATE_DELIVERED;
        String errorCode="000";
        DeliveryReceipt deliveryReceipt = new DeliveryReceipt(dlrId, 1,
                1, submitDate, doneDate,
                state, errorCode, "");



        String shortMessage = deliveryReceipt.toShortMessage();
        deliver.setShortMessage(CharsetUtil.encode(shortMessage, CharsetUtil.CHARSET_GSM));  deliver.calculateAndSetCommandLength();



        DataSmResp dd=new DataSmResp();
        DeliveryReceipt deliveryReceipt=new DeliveryReceipt();
        DeliverSmResp deliverSmResp = new DeliverSmResp();*/


        WindowFuture<Integer, PduRequest, PduResponse> future = session.sendRequestPdu(deliver, 10000, false);
        if (!future.await()) {
            logger.error("Failed to receive deliver_sm_resp within specified time");
        } else if (future.isSuccess()) {
            DeliverSmResp deliverSmResp = (DeliverSmResp) future.getResponse();
            logger.info("deliver_sm_resp: commandStatus [" + deliverSmResp.getCommandStatus() + "=" + deliverSmResp.getResultMessage() + "]");
        } else {
            logger.error("Failed to properly receive deliver_sm_resp: " + future.getCause());
        }
    } catch (Exception e) {
    }
