Daten via Post an php Script senden

[rammi22]

Hallo,
ich versuche mit folgenden Script Daten an ein php-Script via POSt zu versenden, ohne Erfolg,. Als GET angehangen gehts...

JAVA

import java.io.*; 
import java.net.*; 
public class UrlLader2 { 
    
    public static void main( String[] args ){
        
          OutputStream os = null;
          InputStream  is = null;


          try {
              
             // Connection:
             URL           url = new URL( "http://posttestserver.com/post.php" );
             URLConnection con = url.openConnection();
             if( !(con instanceof HttpURLConnection) ) {
                throw new Exception( "Error: Only HTTP allowed." ); 
             }   
             ((HttpURLConnection) con).setRequestMethod( "POST" );
             con.setDoOutput( true );
             // Send data:
             os = con.getOutputStream();
             os.write( "hallo von java ".getBytes() );
             os.flush();
             // Read response:
             is = con.getInputStream();
             int len;
             byte[] buff = new byte[4096];
             while( -1 != (len = is.read( buff )) ) {
                System.out.print( new String( buff, 0, len ) );
             }
             System.out.println();
          } 
          catch( Exception ex ) {
             System.out.println( "\nError: " + ex );
          } 
       }
}

No Post Params.
Empty post body.

Upload contains PUT data: hallo von java

No Post Params? Warum?

Ich hatte das Problem auch erst vor kurzem, bei mir half es, Content-Type und Content-Length zu definieren:

String body = "hallo von java"
connection.setRequestProperty( "Content-Type",
                               "application/x-www-form-urlencoded" );
connection.setRequestProperty( "Content-Length", String.valueOf(body.length()) );
