php与flash as3 socket通讯传递文件实古代码

前段时辰在flashseer看到有人提到:能够经由进程socket体例传递swf文件,让用户没法获得到swf文件… 那时还不出as3的反编译,以是对法式的掩护不在乎.跟着反编译法式的布衣化,不但愿别人看到源代码的伴侣就比拟焦急…

经由进程socket体例传递swf文件来避免泄露源代码的思绪(只合用as3): 让主法式的loader(前台swf)经由进程socket毗连到背景法式,而后要求须要的主法式文件.背景读取主法式数据经由进程socket发送给主法式的 loader.前台swf合用Loader.loadBytes体例显现主法式文件.

上面是测试的源法式:

package {
import flash.display.Sprite;
import flash.net.Socket;
import flash.events.*;
import flash.errors.IOError;
import 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);
   } catch (e:IOError) {
   trace(e);
   }
  }
  function sendRequest():void {
   trace("sendRequest");
   response="";
   writeln("bin");
   socket.flush();
  }
  function readResponse():void {
   //接管数据
   var str:String=socket.readUTFBytes(socket.bytesAvailable);
   response+=str;
   //当数据以end竣事的时辰,数据传输竣事
   if (StringUtil.endsWith(str,"end")) {
   response=response.substr(0,response.length-3);
   //把字符串转换为ByteArray
   var ba=Base64.decodeToByteArray(response);
   //trace("bytearray=====",ba);
   var l:Loader = new Loader();
   //从 ByteArray 工具中所存储的二进制数据中加载。
   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();
  }

  }
}
}

PHP:

//背景scoket法式,因为合用php写比拟简略,就用php写了.
//error_reporting(E_ALL);
error_reporting(0);
set_time_limit(0);
ob_implicit_flush();
$address = "localhost";
$port = 5277;
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {

";
}
if (($ret = socket_bind($sock, $address, $port)) < 0) {
echo "socket_bind() failed: reason: " . socket_strerror($ret) . "
";
}
if (($ret = socket_listen($sock, 5)) < 0) {
echo "socket_listen() failed: reason: " . socket_strerror($ret) . "
";
}
echo "connect…………….";
do {
if (($msgsock = socket_accept($sock)) < 0) {
  echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "
";
  break;
}
do {
  socket_recv($msgsock, $buf, 2048, 0);
  if ($buf == "") {
  socket_close($msgsock);
  echo "some one quit";
  break;
  } else if ($buf == "bin") {
  //读取主法式数据
  $f = fopen("main.swf","r");
  $data = fread($f,filesize("main.swf"));
  fclose($f);
  //转换为字符串
  //echo base64_encode($data);
  $talkback = base64_encode($data)."end";
  }
  //发送
  socket_send($msgsock, $talkback, strlen($talkback),0);
} while (true);
socket_close($msgsock);
} while (true);
socket_close($sock);
