HttpURLConnection

[ryan bohnert]

I am working on a program that sends a request to a url using standalone java. The code below works, but I don't want a bufferedReader object back, all i want to do is make the connection to the url and add "name=ryan&age=28" or whatever i may need to tail end of the URL. I know i could add the name and age logic to the url creation, but i would really like to find out how to use the DataOutputStream to do this.

Any help ? Thanks

    
package com.att.sdrs.ruby;
 
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.MalformedURLException;
import java.io.IOException;
import java.io.*;
 
public class LecNotify{
  public static void main(String [] args){
 
    HttpURLConnection urlConn = null;
    BufferedReader in;
 
    try{
      System.out.println("Starting LecNotify");
      URL url = new URL("www.myurl.com");
      urlConn = (HttpURLConnection)url.openConnection();
      urlConn.setRequestMethod("GET");
      urlConn.setDoInput (true);
      urlConn.setDoOutput (true);
      urlConn.setRequestProperty ("Content-Type","application/x-www-form-urlencoded");
     
      //DataOutputStream out = new DataOutputStream(urlConn.getOutputStream());
      //String content = "MYNAME=RYANBOHNERT";
      //out.writeBytes (content);
      //out.flush();
      //out.close();
 
      in = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
 
      System.out.println("Done");
 
    }catch(MalformedURLException e){
 
    }catch(IOException e){
  
    }catch(Exception e){
      System.out.println(e.getMessage());
      System.out.println(e.getStackTrace());
    }
  }
}

There are two HTTP methods to make requests: GET and POST.

With GET, the parameters are appended to the URL, after a ? and separated by &. So if you want do this with a GET request, you would have to change the URL to: http://www.myurl.com?name=ryan&age=28

With a POST request, you send the data in the request body, which is what you seem to want to do. Here is an example of how to do a POST from Java: http://exampledepot.com/egs/java.net/Post.html
