前言

使用多线程不阻塞的方式，内置自动消息接收和发送的机制，完成对多个客户端连接的消息处理，保证数据处理及时和高量并发的效果

2.核心程序

代码如下：

// 发送线程
DWORD WINAPI cSocketServer::sendCmdDataThread(LPVOID lpParam)
{
	cSocketServer *pMain = (cSocketServer*)lpParam;
	int nStep = 0;
	sUnChokeTimer timer[2];
	int nReConnectTimes = 3 * 1000;
	int nHeatTickTimes = 10 * 1000;
	cSendInfo sendInfo;
	while (true)
	{
		if (pMain->isRelease())
			return 0;
		else
			QThread::msleep(5);

		switch (nStep)
		{
		case 0:
		{
			// 等待服务器启动
			if (!pMain->isStarted())
				QThread::msleep(500);
			else
				nStep = 1;

		}break;

		case 1:
		{
			pMain->operaterClientSocketList(OP_SEND_DATA);
			nStep = 2;
		}break;

		case 2:
		{
			pMain->operaterClientSocketList(OP_DEAL_DATA);
			nStep = 3;
		}break;

		default:
			nStep = 1;
			break;
		}
	}

	return 0;
}

// 接收线程
DWORD WINAPI cSocketServer::recieveCmdDataThread(LPVOID lpParam)
{
	cSocketServer *pMain = (cSocketServer*)lpParam;
	SOCKET socketClient;
	SOCKADDR_IN addrSrv;
	SOCKADDR_IN addrClient;
	int nSockeAddrSize = sizeof(SOCKADDR);
	u_long   ioMode = 1; // 设置接收不阻塞
	int nStep = 0;
	while (true)
	{
		// 资源退出，线程也退出
		if (pMain->isRelease())
			return 0;
		else
			QThread::msleep(5);

		switch (nStep)
		{
		case 0:
		{
			// 等待服务器启动
			if (!pMain->isStarted())
				QThread::msleep(500);
			else
				nStep = 1;
		}break;

		case 1:
		{
			::ioctlsocket(pMain->d_ptr->socket, FIONBIO, (u_long FAR*)&ioMode);
			::ioctlsocket(socketClient, FIONBIO, (u_long FAR*)&ioMode);
			nStep = 2;
		}break;

		case 2:
		{
			socketClient = ::accept(pMain->d_ptr->socket, (sockaddr*)&addrClient, &nSockeAddrSize);
			nStep = 3;
		}break;

		case 3:
		{
			// 判断是否有新的客户端连接
			if (socketClient != SOCKET_ERROR)
			{
				static int nId = 0;
				// 有新客户端连接
				QString strIp = QString("%1").arg(inet_ntoa(addrClient.sin_addr));
				cSocketClient client;
				client.setId(++nId);
				client.setIp(strIp);
				client.setSocket(socketClient);
				pMain->operaterClientSocketList(OP_APPEND_CLIENT, &client);
				emit pMain->sigSocketConnectAlive(client.Ip(), client.id(), true);
			}

			nStep = 4;
		}break;

		case 4:
		{
			// 接收服务端数据
			pMain->operaterClientSocketList(OP_RECIEVE_DATA);
			nStep = 5;
		}break;

		default:
			nStep = 2;
			break;
		}

	}

	return 0;
