问题描述

我发现了客户端/服务器代码,我收到此错误:

I found a client/server code and I am getting this error:

服务器代码:

import java.net.*;
import java.lang.*;
import java.io.*;

public class Server{

//port number should be more than 1024

public static final int PORT = 1025;

public static void main( String args[]) throws IOException
{
 ServerSocket sersock = null;
 Socket sock = null;
 System.out.println(" Wait !! ");

 try
 {
  //  Initialising the ServerSocket
  sersock =  new ServerSocket(PORT);

  // Gives the Server Details Machine name, Port number

  System.out.println("Server Started  :"+sersock);

  try
  {

   // makes a socket connection to particular client after
   // which two way communication take place

   sock = sersock.accept();

   System.out.println("Client Connected  :"+ sock);

   // Receive message from client i.e Request from client

   BufferedReader ins = new BufferedReader(new InputStreamReader(sock.getInputStream()));
   // Send message to the client i.e Response

   PrintStream ios = new PrintStream(sock.getOutputStream());
   ios.println("Hello from server");
   ios.close();

   // Close the Socket connection

    sock.close();

    }
    catch(SocketException se)
    {
    System.out.println("Server Socket problem  "+se.getMessage());
    }
    catch(Exception e)
    {
    System.out.println("Couldn't start "
                  + e.getMessage()) ;
    }

 // Usage of some methods in Socket class

  System.out.println(" Connection from :  " +
  sock.getInetAddress());

 }finally{} // main

}
}// Server class

客户代码:

import java.lang.*;
import java.io.*;
import java.net.*;
import java.net.InetAddress;


public class client
{
 public static void main(String args[])
 {
 Socket sock=null;
 DataInputStream dis=null;
 PrintStream ps=null;
 System.out.println(" Trying to connect");

 try
 {
 // to get the ip address of the  server by the name

 InetAddress ip =InetAddress.getByName
 ("localhost");

 // Connecting to the port 1025 declared in the Serverclass
 // Creates a socket with the server bind to it.

  sock= new Socket(ip,1025);
  ps= new PrintStream(sock.getOutputStream());
  ps.println(" Hi from client");
  BufferedReader is = new BufferedReader(new InputStreamReader(sock.getInputStream()));
  System.out.println(is.readLine());

 }
 catch(SocketException e)
 {
  System.out.println("SocketException " + e);
 }
 catch(IOException e)
 {
  System.out.println("IOException " + e);
 }

  // Finally closing the socket from the client side

 finally
 {
 try
  {
   sock.close();
  }
  catch(IOException ie)
  {
   System.out.println(" Close Error   :" +
   ie.getMessage());
  }
 }  // finally

} // main
}   // Class Client

服务器代码给出以下输出:

The Server code gives the following output:


C:\WorkStation\Testcserver\src>java Server
 Wait !!
Server Started  :ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=1025]
Client Connected  :Socket[addr=/127.0.0.1,port=56143,localport=1025]
 Connection from :  /127.0.0.1

C:\WorkStation\Testcserver\src>

客户端代码提供以下输出:

The client code gives the following output:


C:\WorkStation\testClient\src>java client
 Trying to connect
SocketException java.net.SocketException: Software caused connection abort: recv
 failed



    C:\WorkStation\testClient\src>java client

推荐答案

服务器不等待来自客户端的任何数据,当服务器退出连接时关闭。

The server isn't waiting for any data from the client, and when the server exits the connection will be closed.

ins.readLine()添加到服务器代码中,如下所示:

Add a ins.readLine() to the server code like this:

// Receive message from client i.e Request from client

BufferedReader ins = new BufferedReader(new InputStreamReader(sock.getInputStream()));
System.out.println(ins.readLine());
