php與flash as3 socket通信傳送文件實(shí)現(xiàn)代碼

這篇文章主要介紹了php與flash as3 socket通信傳送文件實(shí)現(xiàn)代碼,本文含AS3代碼和PHP代碼,需要的朋友可以參考下

前段時(shí)間在flashseer看到有人提到:可以通過(guò)socket方式傳送swf文件,讓用戶(hù)無(wú)法獲取到swf文件… 當(dāng)時(shí)還沒(méi)有出as3的反編譯,所以對(duì)程序的保護(hù)沒(méi)有在意.隨著反編譯程序的平民化,不希望別人看到源代碼的朋友就比較著急…

通過(guò)socket方式傳送swf文件來(lái)避免泄漏源代碼的思路(只適用as3): 讓主程序的loader(前臺(tái)swf)通過(guò)socket連接到后臺(tái)程序,然后請(qǐng)求需要的主程序文件.后臺(tái)讀取主程序數(shù)據(jù)通過(guò)socket發(fā)送給主程序的 loader.前臺(tái)swf適用Loader.loadBytes方法顯示主程序文件.

下面是測(cè)試的源程序:

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 {
   //接受數(shù)據(jù)
   var str:String=socket.readUTFBytes(socket.bytesAvailable);
   response+=str;
   //當(dāng)數(shù)據(jù)以end結(jié)束的時(shí)候,數(shù)據(jù)傳輸結(jié)束
   if (StringUtil.endsWith(str,'end')) {
   response=response.substr(0,response.length-3);
   //把字符串轉(zhuǎn)換為ByteArray
   var ba=Base64.decodeToByteArray(response);
   //trace('bytearray=====',ba);
   var l:Loader = new Loader();
   //從 ByteArray 對(duì)象中所存儲(chǔ)的二進(jìn)制數(shù)據(jù)中加載。
   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:

//后臺(tái)scoket程序,由于適用php寫(xiě)比較簡(jiǎn)單,就用php寫(xiě)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) {
echo 'socket_create() failed: reason: ' . socket_strerror($sock) . '\n';
}
if (($ret = socket_bind($sock, $address, $port)) < 0) {
echo 'socket_bind() failed: reason: ' . socket_strerror($ret) . '\n';
}
if (($ret = socket_listen($sock, 5)) < 0) {
echo 'socket_listen() failed: reason: ' . socket_strerror($ret) . '\n';
}
echo 'connect…………….';
do {
if (($msgsock = socket_accept($sock)) < 0) {
  echo 'socket_accept() failed: reason: ' . socket_strerror($msgsock) . '\n';
  break;
}
do {
  socket_recv($msgsock, $buf, 2048, 0);
  if ($buf == "") {
  socket_close($msgsock);
  echo "some one quit";
  break;
  } else if ($buf == "bin") {
  //讀取主程序數(shù)據(jù)
  $f = fopen('main.swf','r');
  $data = fread($f,filesize('main.swf'));
  fclose($f);
  //轉(zhuǎn)換為字符串
  //echo base64_encode($data);
  $talkback = base64_encode($data).'end';
  }
  //發(fā)送
  socket_send($msgsock, $talkback, strlen($talkback),0);
} while (true);
socket_close($msgsock);
} while (true);
socket_close($sock);
