PHP and Flash AS3 Socket Communication transfer file implementation code _php skills

Some time ago in flashseer see someone mentioned: You can transfer the SWF file through the socket, so that users can not get the SWF file ... There was no AS3 at the time, so the protection of the program did not care. With the anti-compiler program of the civilian, do not want others to see the source code friends are more worried ...

Transfer SWF file via socket to avoid leaking source code (AS3 only): Let the main program's loader (front swf) connect to the daemon via the socket, and then request the main program file. Background read main program data sent to main program via socket Loader. Foreground SWF applies the Loader.loadbytes method to display the main program file.

The following is the source program for the test:

Package {import flash.display.Sprite; import flash.net.Socket; import flash.events.*; import flash.errors.IOError; impo

RT Flash.display.Loader;
  public class Sockettest extends Sprite {public Function sockettest () {var socket = new socket ();
  Socket.connect ("localhost", 5277);
  Socket.addeventlistener (Event.close, Closehandler);
  Socket.addeventlistener (Event.connect, Connecthandler);
  Socket.addeventlistener (Ioerrorevent.io_error, Ioerrorhandler);
  Socket.addeventlistener (Securityerrorevent.security_error, Securityerrorhandler);
  Socket.addeventlistener (Progressevent.socket_data, Socketdatahandler);

  var response:string;
   function Writeln (str:string): void {str+= "";
   try {socket.writeutfbytes (str);
   The catch (e:ioerror) {trace (e);
   }} function SendRequest (): void {trace ("SendRequest");
   Response= "";
   Writeln (' bin ');
  Socket.flush (); function Readresponse (): void {//Accept data var str:string=socket.readutfbytes (socket.bytesavailable);
   RESPONSE+=STR;
   When data ends with end, data transfer ends if (stringutil.endswith (str, ' end ')) {response=response.substr (0,response.length-3);
   Converts the string to ByteArray var ba=base64.decodetobytearray (response);
   Trace (' bytearray===== ', BA);
   var l:loader = new Loader ();
   Loaded from binary data stored in the ByteArray object.
   L.loadbytes (BA);
   Trace (l.content);
   AddChild (l);
  } function Closehandler (e:event): void {trace ("Socket closed!");
   function Connecthandler (e:event): void {trace ("Socket connected!");
  SendRequest ();
  function Ioerrorhandler (e:ioerrorevent): void {trace ("ioerror!");
  function Securityerrorhandler (e:securityerrorevent): void {trace ("securityerror!");
   function Socketdatahandler (e:progressevent): void {trace ("Socket have data!");
  Readresponse ();

 }

  }
}
}
