java Jpos Xml传入消息格式

6 日，11 小时 Questions & Answers

我将消息发送到服务器，但得到的响应格式不正确，如下所述 这就是我发送信息的方式

{<isomsg>
<!-- org.jpos.iso.packager.GenericPackager[C:/isoxml/Procenneiso87binary.xml] -->
<field id="0" value="0800"/>
<field id="7" value="1108154836"/>
<field id="11" value="162757"/>
<field id="12" value="094017"/>
<field id="13" value="1109"/>
<field id="70" value="301"/>
</isomsg>

这是来自服务器的响应

 <isomsg direction="incoming">
 <!--org.jpos.iso.packager.GenericPackager[C:/isoxml/Procenneiso87binary.xml] -->
 <header>3038313082</header>
 <field id="0" value="8&#0;&#0;&#2;"/>
 <field id="30" value="&#0;&#0;&#0;110815"/>
</isomsg>
}

我发了回音。 这就是我发送信息的方式

            byte[] tpduHeader = new byte[10];
            tpduHeader = ISOUtil.str2bcd("6000000000", true);
            GenericPackager packager = new GenericPackager(utlOperation.GetConfigStr("IsoXML_Path", "N/A"));
            BaseChannel channel = new NACChannel(packager, tpduHeader);
            channel.setHost(hostName, portNum);
            channel.connect();

            ISOMsg isoMsg = new ISOMsg();
            isoMsg.setPackager(packager);
            isoMsg.setMTI("0800");
            //isoMsg.set(45, keyValue["Field_2"]+"^nidhipathak    ^030912345);
            isoMsg.set(7, "1108154836");
            isoMsg.set(11, "162757");
            isoMsg.set(12, "094017");
            isoMsg.set(13, "1109");
            isoMsg.set(70, "301");
            pLogger.INF("Iso8583 Message Format input - ClientData: " + isoMsg);
            ByteArrayOutputStream str = new ByteArrayOutputStream();
            PrintStream ps = new PrintStream(str);
            org.jpos.util.Logger logger = new org.jpos.util.Logger();
            logger.addListener(new SimpleLogListener(ps));
            //dump the data
            isoMsg.dump(ps, ""); 
            // Get and print the output result
            byte[] RequestedData = isoMsg.pack();
            System.Console.WriteLine(ISOUtil.hexdump(RequestedData));
            System.Console.WriteLine("**" + Hex.encodeHexString(RequestedData) + "**");
            pLogger.INF("HEX Iso8583 Message Format input - ClientData: " + "**" + Hex.encodeHexString(RequestedData) + "**");

            int len = RequestedData.Length;
            byte[] buf = new byte[(len + 2)];
            buf[0] = ((byte)((len >> 8 & 255)));
            buf[1] = ((byte)((len & 255)));
            Array.Copy(RequestedData, 0, buf, 2, len);

            channel.send(buf);

            ISOMsg responseIsoMsg = new ISOMsg();
            responseIsoMsg.setPackager(packager);
            responseIsoMsg = channel.receive();
            byte[] responseData = responseIsoMsg.pack();
            responseIsoMsg.dump(ps, "");
            System.Console.WriteLine(responseIsoMsg);
            channel.getSocket().close();
            channel.disconnect();

事实上，我得到了一个很好的回应，在320消息类型，但我不能阅读传入的消息正确

    是DocType行的错误。我删除了该行，然后用xml linq解析xml：

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;


namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            StreamReader reader = new StreamReader(FILENAME);
            string inputLine = "";
            while((inputLine = reader.ReadLine()) != null)
            {
                if (inputLine.Contains("<! "))
                     break;
            }
            if (!reader.EndOfStream)
            {
                XDocument doc = XDocument.Load(reader);

                var results = doc.Descendants("isopackager").Select(x => new
                {
                    isofields = x.Elements("isofield").Select(y => new
                    {
                        _class = (string)y.Attribute("name"),
                        name = (string)y.Attribute("class"),
                        length = (int)y.Attribute("length"),
                        id = (int)y.Attribute("id")
                    }).ToList(),
                    isofieldpackager = x.Elements("isofieldpackager").Select(y => new
                    {
                        _class = (string)y.Attribute("name"),
                        name = (string)y.Attribute("class"),
                        length = (int)y.Attribute("length"),
                        id = (int)y.Attribute("id"),
                        packager = (string)y.Attribute("packager"),
                        isofields = x.Elements("isofield").Select(z => new
                        {
                            _class = (string)z.Attribute("name"),
                            name = (string)z.Attribute("class"),
                            length = (int)z.Attribute("length"),
                            id = (int)z.Attribute("id")
                        }).ToList()
                    }).FirstOrDefault(),
                }).FirstOrDefault();
            }

        }
    }
