層次結構

每一層都定義了抽象的接口，只要實現相應的接口，可以方便的對每一層進行擴展。每一個介面都提供了一個基類實現，可以繼承該基類，然後重寫想要修改的方法即可。

• Transport層負責網路相關的功能，目前支援TCP，WebSocket

      type ITransport interface {
          GetId () uint32
          GetLocalAddr () string
          GetRemoteAddr () string
          Listen () error
          Connect () error
          OnNewConnect ( transport ITransport )
          Read ()
          Write ()
          Send ( msgPkg IMessagePackage ) error
          Close ()
          OnClosed ()
          IsStop () bool
          IsTimeout ( tick * time. Timer ) bool
      }

• Protocol層負責協定解析，目前支援ProtoBuff，Gob編碼協定

      type IProtocol interface {
      	Marshal ( msg interface {}) ([] byte , error )
      	Unmarshal ( data [] byte , v interface {}) error
      }

• MsgHandle層負責訊息分發

      type IMsgHandle interface {
          RegisterMsg ( tag uint32 , msg interface {})
          NewMsg ( tag uint32 ) interface {}
          GetMsgTag ( msg interface {}) uint32
          SetProtocol ( protocol IProtocol )
          GetProtocol () IProtocol
          CreateMessage ( msgPkg IMessagePackage ) interface {}
          CreateMessagePackage ( msg interface {}) IMessagePackage
          Process ( transport ITransport , msgPackage IMessagePackage )
          SetOnTransportClose ( f func ( transport ITransport ))
          OnTransportClose ( transport ITransport )
      }

範例

建構一個服務只需組合上述三個層次的結構，即可客製化所需的服務

 //服务器逻辑
func serverStart () {
    //选择协议
    protocol := & lprotocol. PbProtocol {}
    //选择消息处理函数
    msgHandle := lmsghandle . NewBaseMsgHandle ( protocol )
    //注册消息
    msgHandle . RegisterMsg ( 12 , pb. GameItem {})
    msgHandle . RegisterMsg ( 13 , pb. RpcReqData {})
    msgHandle . RegisterMsg ( 14 , pb. RpcRspData {})
    //启动服务
    server := lserver . NewTcpServer ( "127.0.0.1:9000" , msgHandle )
    server . Start ()
}

//客户端逻辑
func clientStart () {
    //选择协议
    protocol := & lprotocol. PbProtocol {}
    //选择消息处理函数
    msgHandle := lmsghandle . NewBaseMsgHandle ( protocol )
    //注册消息
    msgHandle . RegisterMsg ( 12 , pb. GameItem {})
    msgHandle . RegisterMsg ( 13 , pb. RpcReqData {})
    msgHandle . RegisterMsg ( 14 , pb. RpcRspData {})

    client := lclient . NewTcpClient ( "127.0.0.1:9000" , msgHandle )
    client . Connect ()

    msg := & pb. GameItem { Id : 1 , Type : 2 , Count : 3 }
    for {
        client . Send ( msg )
        time . Sleep ( 1 * time . Second )
    }
}
