寻找一种方法来返回带有来自cloudhopper smpp服务器的错误代码的DeliverSmResp

Question

我正在寻找一种方法将SMPP错误代码从服务器发送到连接的客户端。我的流程是：1。客户端发送到我的服务器短信2.我发送到另一个系统3.当我得到消息的状态（可能需要长达72小时）我想将结果发送回连接的客户端作为接收者。我也注意到，当我发送给客户时，我看到：

默认处理是丢弃意外响应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);
        }
    }

我寻找一种方法来返回方法sendResponsePdu发生错误时的SMPP错误代码

我希望在客户端看到错误代码0xa，这意味着“无效的源地址”，但通常ESME_ROK我从C＃项目中获取图像，我可以看到从SMSC 发送时的响应应该是什么样子

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

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) {
    }
