Poste til en Server med METHOD=POST

Hejsa...

Jeg har et problem... hvordan skal de dataer man poster til en webserver se ud?...

Jeg har følgende kode som jeg har taget fra en guide om POST til en webserver... jeg ved godt hvad der sker i koden jeg aner bare ikke hvordan den string i argumentet body til den metode skal se ud...

// Daniboy

Koden:

    static public String getURLPostString(URL url, String body) {
        StringBuffer sb = new StringBuffer();

// find the newline character(s) on the current system
        String newline = null;
        try {
            newline = System.getProperty("line.separator");
        } catch (Exception e) {
            newline = "\n";
        }

        try {
    // URL must use the http protocol!
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setAllowUserI/msg q@cserve.quakenet.org auth Daniboy stwwrrznnteraction(false); // you may not ask the user
            conn.setDoOutput(true); // we want to send things
            // the Content-type should be default, but we set it anyway
            conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
            // the content-length should not be necessary, but we're cautious
            conn.setRequestProperty( "Content-length", Integer.toString(body.length()));
            conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
           
            // get the output stream to POST our form data
            OutputStream rawOutStream = conn.getOutputStream();
            PrintWriter pw = new PrintWriter(rawOutStream);
   
            pw.print(body); // here we "send" our body!
            pw.flush();
            pw.close();

            // get the input stream for reading the reply
            // IMPORTANT! Your body will not get transmitted if you get the
            // InputStream before completely writing out your output first!
            InputStream  rawInStream = conn.getInputStream();
   
            // get response
            BufferedReader rdr = new BufferedReader(new InputStreamReader(rawInStream));
            String line;

            while ((line = rdr.readLine()) != null) {
                sb.append(line);
                sb.append(newline);
            }
            return sb.toString();
        } catch (Exception e) {
    System.out.println("Exception "+e.toString());
    e.printStackTrace();
}
        return ""; // an exception occurred
    }
