Discussion of communication between C # Server and Java client based on Networkcomms V3 communication framework

First of all, the NETWORKCOMMS communication Framework is a commercial version, this article does not provide.

Not familiar with Java, just installed Eclipse, communication only implements the characters from the Java client to the C # server, the server receives a message, returns a character message to the Java client, the Java client displays the received message.

Server-side based Networkcomms V3 C # communication framework.

Server-side code:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingnetworkcommsdotnet;usingnetworkcommsdotnet.dpsbase;usingNetworkcommsdotnet.tools;usingnetworkcommsdotnet.connections;usingNetworkCommsDotNet.Connections.TCP;usingSystem.Net;usingMessageContract;namespaceserver{ Public Partial classform1:form {sendreceiveoptions SRO=NewSendreceiveoptions (dpsmanager.getdataserializer<nullserializer> (),NULL,NULL);  PublicForm1 () {InitializeComponent (); }        Private voidButton1_Click (Objectsender, EventArgs e) {            //server starts listening for client requests//start listening on a port//communication with other languages disabled ApplicationlayerprotocolstatusTcpconnectionlistener listener=NewTcpconnectionlistener (sro,applicationlayerprotocolstatus.disabled); Connection.startlistening (Listener,NewIPEndPoint (Ipaddress.parse (Txtip.text),int.                      Parse (Txtport.text)); Button1. Text="Listening in"; Button1. Enabled=false; //This method contains server-specific processing methods. startlistening (); }        Private voidstartlistening () {networkcomms.disablelogging (); //Array received bytesNetworkcomms.appendglobalincomingunmanagedpackethandler (header, connection, array) =            {                //C # language UTF-8 byte array converted to string                stringRecvstr = Encoding.UTF8.GetString (Array,0, Array.                                 Length); //record the proof that the message has been received                stringNewstr ="the received string is"+Recvstr; Loginfo.logmessage (Newstr,"log. txt"); //return message to Java client                stringServerstr ="message sent by the server 123"; byte[] Newbyte =Encoding.UTF8.GetBytes (SERVERSTR); //Send byte dataconnection.             Sendunmanagedbytes (Newbyte);                     }); }             Private voidForm1_formclosing_1 (Objectsender, FormClosingEventArgs e)            {Networkcomms.shutdown ();        Environment.exit (Environment.exitcode); }    }}

Client interface:

Client Java code (not very familiar with Java, the code may be inappropriate):

Package Com.yee4.liu;import Java.io.BufferedReader;  Import Java.io.InputStream;  Import Java.io.InputStreamReader;  Import Java.io.OutputStream;  Import Java.io.PrintWriter;   Import Java.net.Socket;  Public classHelloWorld extends thread{ Public Static byte[] Readstream (InputStream instream) throws Exception {intCount =0;  while(Count = =0) {Count=instream.available (); }          byte[] B =New byte[Count];          Instream.read (b); returnb; }      /** * @param args*/     Public Static voidMain (string[] args) throws Exception {socket Socket=NULL; intj =0; Try{Socket=NewSocket ("127.0.0.1", the); if(socket.isconnected ()) {System. out. println ("A connection has been established!---"); String strcontent="messages sent by Java"; byte[] bs = Strcontent.getbytes ("UTF-8"); //2. Get socket read/write streamOutputStream os=Socket.getoutputstream (); //3. Use the stream to read and write the socket according to certain operationOs.write (BS);                                                                      Os.flush (); System. out. println ("----------------------------------"); InputStream IPs=Socket.getinputstream (); byte[] Rebyte =Readstream (IPS); String ResultStr=NewString (Rebyte,0, Rebyte.length,"UTF-8"); System. out. println ("Receive host message:"+resultstr); }                     }                   Catch(Exception s) {System. out. Print (s); }            }    }

Review the process

(1): Open C # program, start listening

(2): Run the Java client and send a message to the C # server

    String strcontent="messages sent by Java ";                             byte [] bs = Strcontent.getbytes ("UTF-8");                                 // 2. Get socket read/  write stream                OutputStream os=socket.getoutputstream ();                                    // 3. Use the stream to read and write  the socket according to certain operation                             Os.write (BS);                Os.flush ();               

(3): After the C # server receives the message, it parses

<1>:

  //   C # language UTF-8 byte array converted to string                string 0 , Array. Length);                                  // record the proof that the message has been received                string " the received string is " + recvstr;                 " log. txt ");

<2> return message to the Java client:

  // return message to Java client                string " message sent by the server 123 " ;                 byte [] Newbyte = Encoding.UTF8.GetBytes (serverstr);                 // Send byte data                

(4): The Java client receives the message and displays it

  InputStream ips = socket.getinputstream ();                   byte [] Rebyte = readstream (IPs);                                        New 0 " UTF-8 " );                 System. out. println (" received host message:" + resultstr);  

The Java program appears to have exited after receiving the message, and I don't know how to handle it.

The program is only successful in My Computer test, Win7 system, not tested on other systems.
