奇迹世界服务器架构(2)

b、代码实现连接

连接每个服务器都用继承自ServerSession 的类实现

有如下类

AgentServerSession

BattleServerSession

FieldServerSession

GameDBProxySession

GuildServerSession

MasterServerSession

基类ServerSession 有 update 实现心跳连接

VOID ServerSession::Update()
{
if( IsForConnect() )
{
   // heartbeat 焊郴扁
   DWORD dwCurTick = GetTickCount();
   if( dwCurTick - m_dwLastHeartbeatTick > 10000 )
   {
    m_dwLastHeartbeatTick = dwCurTick;

    MSG_HEARTBEAT msg;
    msg.m_byCategory   = 0;
    msg.m_byProtocol   = SERVERCOMMON_HEARTBEAT;
    Send( (BYTE*)&msg, sizeof(MSG_HEARTBEAT) );
   }
}
}

每个Session要连接服务器的时候

VOID GameDBProxySession::OnConnect( BOOL bSuccess, DWORD dwSessionIndex )
{
ServerSession::OnConnect( bSuccess, dwSessionIndex );

if( bSuccess )
{
   ServerSession::SendServerType();

   g_pGameServer->ConnectTo( AGENT_SERVER );
}
else
{
   //SUNLOG( eFULL_LOG, "Can't connect to game DB proxy." );
}
}

VOID GameServer::ConnectTo( eSERVER_TYPE eServerType )
{
switch( eServerType )
{
case MASTER_SERVER:
   ConnectToServer( m_pMasterServerSession,
    (char*)m_pMasterServerSession->GetConnectIP().c_str(), m_pMasterServerSession->GetConnectPort() );
        break;

case GAME_DBPROXY:
   ConnectToServer( m_pGameDBProxySession,
    (char*)m_pGameDBProxySession->GetConnectIP().c_str(), m_pGameDBProxySession->GetConnectPort() );
   break;

case AGENT_SERVER:
   ConnectToServer( m_pAgentServerSession,
    (char*)m_pAgentServerSession->GetConnectIP().c_str(), m_pAgentServerSession->GetConnectPort() );
   break;
case GUILD_SERVER:
   ConnectToServer( m_pGuildServerSession,
    (char*)m_pGuildServerSession->GetConnectIP().c_str(), m_pGuildServerSession->GetConnectPort() );
   break;

default:
   ASSERT( !"弊繁 辑滚 鸥涝篮 绝绢夸" );
}
}

DWORD GameServer::ConnectToServer( NetworkObject * pNetworkObject, char * pszIP, WORD wPort )
{
return m_pIOCPServer->Connect( SERVER_IOHANDLER, pNetworkObject, pszIP, wPort );
}

DWORD IOCPServer::Connect( DWORD dwIoHandlerKey, NetworkObject *pNetworkObject, char *pszIP, WORD wPort )
{
if( pNetworkObject == NULL ) return 0;

IOHANDLER_MAP_ITER it = m_mapIoHandlers.find( dwIoHandlerKey );

assert( it != m_mapIoHandlers.end() );

return it->second->Connect( pNetworkObject, pszIP, wPort );
}

c、代码实现监听

VOID GameServer::StartListen()
{
SERVER_ENV * pServerEnv = m_pFileParser->GetServerEnv();

if( !m_pIOCPServer->IsListening( SERVER_IOHANDLER ) )
{
   DISPMSG( "[GameServer::StartListen] Starting listen(%s:%d)...\n", pServerEnv->ServerIoHandler.szIP, pServerEnv->ServerIoHandler.wPort );
   if( !m_pIOCPServer->StartListen( SERVER_IOHANDLER, pServerEnv->ServerIoHandler.szIP, pServerEnv->ServerIoHandler.wPort ) )
   {
    DISP_FAIL;
    return ;
   }
   DISP_OK;
}
}

BOOL IOCPServer::StartListen( DWORD dwIoHandlerKey, char *pIP, WORD wPort )
{
IOHANDLER_MAP_ITER it = m_mapIoHandlers.find( dwIoHandlerKey );

assert( it != m_mapIoHandlers.end() );

return it->second->StartListen( pIP, wPort );
}
