Write a program that connects to TCP port 80 on server home.adelphi.edu. Upon connection, send the following output from your program back to the server:

Note that the extra empty line is important!

As you read back what the server sends back to you, you'll find it sends a number of lines that consist of Key: Value pairs, followed by a blank line, followed by more text.

The first part of the response are headers, and they describe the rest of the response, which is known as thebody.

In this case, the server is expected to close the connection after sending the body, but it doesn't. Your program should scan each line that comes back from the server and terminate the connection after it receives a response with the phrase "degrees F" in it.

Have your program print out ONLY the digits of the temperature. This is the temperature measured in the Computer Science lab in SCB401.

class TCPClient {
   public static void main(String argv[]) throws Exception {
       String modifiedSentence;
       Socket clientSocket = new Socket("home.adelphi.edu", 80);
       DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());
       BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
       String toSend = "GET /~leune/temperature/temp_now.txt HTTP/1.0 ";
       outToServer.writeBytes(toSend + ' ');
       modifiedSentence = inFromServer.readLine();
       System.out.println("FROM SERVER: " + modifiedSentence);
       clientSocket.close();
   }
}

Explanation / Answer

import java.io.*;

import java.net.*;

public class TcpClient

{

    public static void main(String[] args) throws IOException

    {

        Socket clientSocket = new Socket();

    String host = "home.adelphi.edu";

    PrintWriter s_out = null;

    BufferedReader inFromServer = null;

         

        try

        {

        clientSocket.connect(new InetSocketAddress(host , 80));

        System.out.println("Connected");

             

        //writer for socket

            s_out = new PrintWriter( clientSocket.getOutputStream(), true);

            //reader for socket

            inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

        }

         

        //Host not found

        catch (UnknownHostException e)

        {

            System.err.println("Don't know about host : " + host);

            System.exit(1);

        }

         

        //Send message to server

    String toSend = GET/~leune/temperature/temp_now.txtHTTP/1.0 "    

s_out.println( toSend );

             

    System.out.println("Message send");

         

    //Get response from server

    String modifiedSentence;

    while ((modifiedSentence = inFromServer.readLine()) != null)

    {

        System.out.println(“From Server:”+modifiedSentence );

    }

//close the i/o streams

s_out.close();

inFromServer.close();

         

//close the socket

clientSocket.close();

    }

}
