                             ActionScript 3.0中用XMLSocket与服务器通讯程序——源码

   一个简单的基于XMLSocket的封装类

// // CXMLSocket.as // // // Written by Leezhm, 20th Oct, 2008 // Contact : Leezhm@luxoom.cn // package { import flash.events.DataEvent; import flash.events.Event; import flash.events.IEventDispatcher; import flash.events.IOErrorEvent; import flash.events.ProgressEvent; import flash.events.SecurityErrorEvent; import flash.net.XMLSocket; import flash.system.Security; public class CXMLSocket extends XMLSocket { // declare variables private var mHostName:String = "127.0.0.1"; private var mPort:int = 7654; private var mStrRecvBuf:String; // constructor public function CXMLSocket():void { //ConfigNetEvent(this); Connect(); } public function Connect():void { var xmlStr:String = "xmlsocket://"; xmlStr += mHostName; xmlStr += ":"; xmlStr += mPort; Security.loadPolicyFile(xmlStr); trace(xmlStr); ConfigNetEvent(this); this.connect(mHostName, mPort); } private function ConfigNetEvent(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.CONNECT, OnConnect); dispatcher.addEventListener(Event.CLOSE, OnClose); dispatcher.addEventListener(DataEvent.DATA, OnSocketData); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, OnIOError); dispatcher.addEventListener(ProgressEvent.PROGRESS, OnProgress); dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, OnSecurityError); } private function OnConnect(ArgEvent:Event):void { trace("OnConnect--->" + ArgEvent); this.send("Connected"); } private function OnClose(ArgEvent:Event):void { trace("OnClose--->" + ArgEvent); } private function OnSocketData(ArgEvent:DataEvent):void { trace(ArgEvent.text); } private function OnIOError(ArgEvent:IOErrorEvent):void { trace("OnIOError--->" + ArgEvent.text); } private function OnProgress(ArgEvent:ProgressEvent):void { trace("OnProgress--->" + ArgEvent.bytesLoaded + " Total:" + ArgEvent.bytesTotal); } private function OnSecurityError(ArgEvent:SecurityErrorEvent):void { trace("OnSecurityError--->" + ArgEvent); } } } 

 基于C++的服务器源码：

// Server.cpp : implementation file // #include "stdafx.h" #include "Server.h" #include "SerialPort.h" extern CSerialPort m_Ports; // CServer extern CPtrArray gSocketArr; extern bool gbIsConnected; CServer::CServer():mStrSendBuf("") { //bIsConnectFlash = false; } CServer::~CServer() { } // CServer member functions void CServer::OnAccept(int nErrorCode) { // TODO: Add your specialized code here and/or call the base class if(0 == nErrorCode) { CServer * pSocket = new CServer(); if(SOCKET_ERROR != this->Accept(*pSocket)) { gSocketArr.Add(pSocket); } else { ::AfxMessageBox(_T("Accept->Error")); } pSocket = NULL; } CAsyncSocket::OnAccept(nErrorCode); } void CServer::OnReceive(int nErrorCode) { // TODO: Add your specialized code here and/or call the base class if(0 == nErrorCode) { char buf[30] = {0}; int nRead = this->Receive(buf, 30); if(0 != nRead && SOCKET_ERROR != nRead) { // // debug info // std::fstream debug; debug.open(_T("Debug.txt"), std::ios::app); int yvalue; if(debug.is_open()) { debug<<buf<<"/n"; yvalue = atoi(buf); //m_Ports.WriteToPort( } debug.close(); if(0 == strcmp("<policy-file-request/>", buf)) { std::string strXML = "<cross-domain-policy>"; strXML += "<allow-access-from domain=/"*/"to-ports=/"*/"/>"; //strXML += "<allow-access-from domain=/"localhost/"to-ports=/"1025,9999/"/>"; strXML += "</cross-domain-policy>"; strXML += "/0/0"; this->Send(strXML.c_str(), (int)strXML.length() + 1); gbIsConnected = true; } else if(0 == strcmp("Connected", buf)) { ////::AfxMessageBox(_T("Hello")); gbIsConnected = true; } } } CAsyncSocket::OnReceive(nErrorCode); } void CServer::SendData() { if(0 == gSocketArr.IsEmpty()) { for(int i = 0; i < gSocketArr.GetSize(); i++) { ((CServer *)gSocketArr[i])->Send(mStrSendBuf.c_str(), (int)mStrSendBuf.length() + 1); } std::fstream debug; debug.open(_T("Debug.txt"), std::ios::app); int yvalue; if(debug.is_open()) { debug<<mStrSendBuf<<"/n"; } debug.close(); } else { ::AfxMessageBox(_T("Socket Error")); } }  

   注意服务器端程序是继承了MFC中CAsyncSocket的一个异步socket类
