利用Socket实现C++与Flex通信
|
一、
C++
服务器端
（用的是
Visual Studio 2008
（
05
，
03
的应该也可以，
VC++
的可能需要稍微改动））
代码如下：
#include
<winsock2.h>
#include
<stdio.h>
#include
<windows.h>
#include
<iostream>
using
namespace std;
#pragma
comment(lib,"ws2_32.lib")
void
main(){
WORD wVersionRequested;
WSADATA wsaData;
int err;
short port=1300;//
端口号
wVersionRequested = MAKEWORD( 1, 1 );
err = WSAStartup( wVersionRequested, &wsaData );//
初始化套接字
if ( err != 0 )
{
return;
}
if ( LOBYTE( wsaData.wVersion ) != 1 || HIBYTE( wsaData.wVersion ) != 1 )
{
WSACleanup( );
return;
}
SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);//
创建套接字
SOCKET sockConn;//
用来和客户端通信的套接字
SOCKADDR_IN addrSrv;//
用来和客户端通信的套接字地址
addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
addrSrv.sin_family=AF_INET;
addrSrv.sin_port=htons(port);
bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));//
绑定端口
listen(sockSrv,5);//
侦听
printf("Server %d is listening....../n",port);
SOCKADDR_IN addrClient;
int len=sizeof(SOCKADDR);
char
buf[4096];//
接收的数据
char
rbuf[100]="
成功"
;//
返回的数据
while(1)
{
//
接受连接
sockConn=accept(sockSrv,(SOCKADDR*)&addrClient,&len);
printf("Accept connection from %s/n",inet_ntoa(addrClient.sin_addr));
//
接收数据
int bytes;
if((bytes=recv(sockConn,buf,sizeof(buf),0))==SOCKET_ERROR){
printf("
接收数据失败!/n"
);
exit(-1);
}
buf[bytes]='/0';
printf("Message from %s: %s/n",inet_ntoa(addrClient.sin_addr),buf);
//
发送数据
if(send(sockConn,rbuf,strlen(rbuf)+1,0)==SOCKET_ERROR){
printf("
发送数据失败！"
);
exit(-1);
}
printf("Message to %s: %s/n",inet_ntoa(addrClient.sin_addr),rbuf);
//
清理套接字占用的资源
closesocket(sockConn);
}
}
运行效果如下：
二、
Flex
客户端（
Flex Builder
）
代码如下
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication
xmlns:mx="
http://www.adobe.com/2006/mxml
" layout="
absolute
"
creationComplete="initApp();"
>
<mx:Script>
<![CDATA[
import flash.net.Socket;
private var socket:Socket;
private function initApp():void
{
}
private function StartTest():void
{
socket =
new Socket("127.0.0.1",1300);
socket.addEventListener(Event.CONNECT, connectHandler);
socket.addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
}
private function CloseTest():void
{
if(socket!=null && socket.connected)
{
trace("socket.connected:"+socket.connected);
socket.close();
trace("socket.connected:"+socket.connected);
}
}
private function connectHandler(event:Event):void
{
trace("connectHandler: " + event);
socket.writeMultiByte(SendStr.text,
"GB2312");
socket.flush();
}
private function socketDataHandler(event:ProgressEvent):void
{
trace("socketDataHandler: " + event);
var str:String=socket.readMultiByte(socket.bytesAvailable,"GB2312");
ReceiveStr.text = str;
}
]]>
</mx:Script>
<mx:Text
text="
发送
" y="
11
" x="
18
" fontWeight="
bold
" color="
#ffffff
"
/>
<mx:TextArea
id="
ReceiveStr
" x="
53
" y="
68
"
/>
<mx:Text
text="
接收
" y="
69
" x="
18
" fontWeight="
bold
" color="
#ffffff
"
/>
<mx:TextArea
id="
SendStr
" y="
10
" x="
53
"
/>
<mx:Button
label="
Start
" click="StartTest()" x="
53
" y="
120
"
/>
<mx:Button
label="
Close
" click="CloseTest()" x="
126
" y="
120
"
/>
</mx:WindowedApplication>
三、运行
先运行
C++
服务器端，再运行
Flex
客户端，成功后如下图所示
