code: select all

   
   1. public class urltest2 { 
   2.   
   3.     public static void main( string[] args ) { 
   4.       
   5.         try { 
   6.           
   7.             string data1 = urlencoder.encode("first", "utf-8") + "=" + urlencoder.encode("fred", "utf-8"); 
   8.             string data2 = urlencoder.encode("last", "utf-8") + "=" + urlencoder.encode("hamilton", "utf-8"); 
   9.             string data = data1 +"&" +data2; 
  10.           
  11.             string inline; 
  12.           
  13.             url u1 = new url("http://192.168.0.10/test1/test2.php"); 
  14.             urlconnection uc1 = u1.openconnection(); 
  15.               
  16.             uc1.setdooutput(true); 
  17.             outputstreamwriter out = new outputstreamwriter(uc1.getoutputstream()); 
  18.             out.write(data); 
  19.             out.flush(); 
  20.           
  21.             bufferedreader in = new bufferedreader( new inputstreamreader( uc1.getinputstream() ) ); 
  22.   
  23.             while ((inline = in.readline()) != null) { 
  24.                 system.out.println(inline); 
  25.             } 
  26.           
  27.             in.close(); 
  28.         } 
  29.         catch( exception e ) { 
  30.             e.printstacktrace(); 
  31.         } 
  32.     } 
  33. } 


and php handles response:

code: select all

   
   1. <?php 
   2.   
   3. $first = $_post["first"]; 
   4. $last = $_post["last"]; 
   5.   
   6. echo 'welcome guy '; 
   7. echo $first; 
   8. echo $last; 
   9.   
  10. ?> 


thank you,
