Flex and Java Socket Communication (ii) one-way communication

Purpose: The client sends a message to the server, and the server displays the message on the screen without sending any data to the client.

The server will repeat the process.

1 Waiting for Client connection requests

2 Connecting Clients

3 Receive a string before disconnecting the client

4 Disconnect client Connections

5 Back to first step

Gets the input stream for the socket connected to the client, as follows.

Socket socket=server.accept();　//返回与客户机连接的套接字
InputStream is=socket.getInputStream();　　//获取套接字的InputStream
InputStreamReader isr=new InputStreamReader(is);
BufferedReader reader= new BufferedReader(isr);　//字符串流

Service-side code: Server2.java

=========================================

Import java.net.*;
Import java.io.*;
public class Server2 {
Private BufferedReader reader; Responsible for input
Private ServerSocket server; Server sockets
private socket socket; Sockets
Public Server2 () {}//default constructor
void StartServer ()//Start server
{
Try
{
Server=new ServerSocket (8888); Create a server socket
SYSTEM.OUT.PRINTLN ("Server socket set up");
while (true)
{
System.out.println ("Waiting for Client");
Socket=server.accept (); If the client requests a connection, connect to the socket
SYSTEM.OUT.PRINTLN ("Complete connection to client");
Get socket input stream, "utf-8" This encoding setting is to better display Chinese
Reader=new BufferedReader (New InputStreamReader (Socket.getinputstream (), "UTF-8"));
GetMessage ()//Read data from the client and output to the screen
}
}catch (Exception e)
{
System.out.println (e);
}
}
void GetMessage ()//read information from sockets
{
Try
{
while (true)//loop
{
SYSTEM.OUT.PRINTLN ("Client:" +reader.readline ());
}
}catch (Exception e) {}
finally{
SYSTEM.OUT.PRINTLN ("Client Disconnected");
Try
{
if (reader!=null) reader.close (); Close the input stream for a socket
if (socket!=null) socket.close (); Close socket

}catch (Exception e) {}
