  • 通过socket方式传送swf文件来避免泄漏

    通过socket方式传送swf文件来避免泄漏源代码的思路(只适用as3): 让主程序的loader(前台swf)通过socket连接到后台程序,然后请求需要的主程序文件.后台读取主程序数据通过socket发送给主程序的loader.前台swf适用Loader.loadBytes方法显示主程序文件.

    下面是测试的源程序:

    前台loader:
    //-------------
    //Base64和StringUtil在网上自己找吧
    import Base64;
    import StringUtil;
    var socket = new Socket();
    socket.connect("localhost", 11915);

    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 {
    //接受数据
    var str:String = socket.readUTFBytes(socket.bytesAvailable);
    response += str;
    //当数据以end结束的时候,数据传输结束
    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 loader = new Loader();
    //从 ByteArray 对象中所存储的二进制数据中加载
       l.loadBytes(ba);
       //trace(l.content);
       addChild(l);
    }
    }


    function closeHandler(event:Event):void {
    trace("closeHandler: " + event);
    }

    function connectHandler(event:Event):void {
    trace("connectHandler: " + event);
    sendRequest();
    }

    function ioErrorHandler(event:IOErrorEvent):void {
    trace("ioErrorHandler: " + event);
    }

    function securityErrorHandler(event:SecurityErrorEvent):void {
    trace("securityErrorHandler: " + event);
    }

    function socketDataHandler(eventrogressEvent):void {
    trace("socketDataHandler: " + event);
    readResponse();
    }

    //后台scoket程序,由于适用php写比较简单,就用php写了.
    <?php
    //error_reporting(E_ALL);
    error_reporting(0);
    set_time_limit(0);

    ob_implicit_flush();

    $address = 'localhost';
    $port = 11915;

    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')
       {
    //读取主程序数据
    $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);
    ?>
