从0到1开发go-tcp框架【2-实现Message模块、解决TCP粘包问题、实现多路由机制】

1 实现\封装Message模块

zinx/ziface/imessage.go

package zifacetype IMessage interface {GetMsdId() uint32GetMsgLen() uint32GetMsgData() []byteSetMsgId(uint32)SetData([]byte)SetDataLen(uint32)
}

zinx/znet/message.go

package znettype Message struct {//消息idId uint32//消息长度DataLen uint32//消息内容Data []byte
}func (m *Message) GetMsdId() uint32 {return m.Id
}
func (m *Message) GetMsgLen() uint32 {return m.DataLen
}
func (m *Message) GetMsgData() []byte {return m.Data
}func (m *Message) SetMsgId(id uint32) {m.Id = id
}
func (m *Message) SetData(data []byte) {m.Data = data
}
func (m *Message) SetDataLen(len uint32) {m.DataLen = len
}

2 解决TCP粘包问题（TLV方式）

2.1 解决思路

大家都知道TCP是一种流式传输（所谓流式，也就是没有截止，因此会出现粘包的问题，因为我们不知道读多少数据结束一个包）
解决思路：TLV:type、length、value

• 每个数据包都封装上TLV，告诉对方我们消息的类型，我们消息的长度（设定为占固定长度，如8字节）。
• 这样对方在接受的时候，每次先读8字节，拿到类型和长度，最后再根据类型和长度读取对应数量的数据

2.2 封包拆包过程实现

①zinx/ziface/idatapack.go

package zifacetype IDataPack interface {//获取包头的长度GetHeadLen() uint32//封包方法1Pack(msg IMessage) ([]byte, error)//拆包UnPack([]byte) (IMessage, error)
}

②zinx/znet/datapack.go

实现封包，拆包方法

• 写入数据头

package znetimport ("bytes""encoding/binary""github.com/kataras/iris/v12/x/errors""myTest/zinx/util""myTest/zinx/ziface"
)type DataPack struct {
}func NewDataPack() *DataPack {return &DataPack{}
}//获取包头的长度
func (dp *DataPack) GetHeadLen() uint32 {//DataLen uint32 4字节 + ID uint32 4字节,固定包头的长度return 8
}//封包方法
func (dp *DataPack) Pack(msg ziface.IMessage) ([]byte, error) {//创建一个存放bytes字节的缓冲dataBuf := bytes.NewBuffer([]byte{})//包的格式【包长度、包Id、包数据】//1 先写dataLen写入dataBuf中，采用小端写if err := binary.Write(dataBuf, binary.LittleEndian, msg.GetMsgLen()); err != nil {return nil, err}//2 写入msgIdif err := binary.Write(dataBuf, binary.LittleEndian, msg.GetMsdId()); err != nil {return nil, err}//3 写入具体数据if err := binary.Write(dataBuf, binary.LittleEndian, msg.GetMsgData()); err != nil {return nil, err}return dataBuf.Bytes(), nil
}//拆包:将包的head信息都提取出来（包的id、长度），然后再根据包的长度一次性读取数据
func (dp *DataPack) UnPack(binaryData []byte) (ziface.IMessage, error) {dataBuf := bytes.NewReader(binaryData)//先解压head信息，得到dataLen和msgIdmsg := &Message{}//dataLenif err := binary.Read(dataBuf, binary.LittleEndian, &msg.DataLen); err != nil {return nil, err}//msgIdif err := binary.Read(dataBuf, binary.LittleEndian, &msg.Id); err != nil {return nil, err}//判断dataLen是否已经超过了我们在zinx.json配置文件中所允许的包最大长度if util.GlobalObject.MaxPackageSize > 0 && msg.DataLen > util.GlobalObject.MaxPackageSize {return nil, errors.New("too large msg data receive")}//msg中只包含：dataLen和dataIdreturn msg, nil
}

③测试:zinx/znet/datapack_test.go

在测试的时候可以先把util/globalobj.go中GlobalObject.Reload()注释掉，因为我们是通过go自带的test框架测试，所以会读取不到配置文件

zinx/znet/datapack_test.go
注意：go的test文件名必须是xxxx_test.go

package znetimport ("fmt""io""net""testing"
)//测试dataPack的拆包、封包
func TestDataPack(t *testing.T) {/*1 模拟服务器*/listener, err := net.Listen("tcp", "127.0.0.1:7777")if err != nil {fmt.Println("server listen err ", err)return}//启动协程，用于处理客户端的业务go func() {//2 从客户端读取数据，进行拆包conn, err := listener.Accept()if err != nil {fmt.Println("server accept err ", err)return}go func(conn net.Conn) {//处理客户端的请求//>-----拆包过程------<dp := NewDataPack()for {// ①第一次从conn中读，将包中的head读取出来[我们定义的headLen默认是8字节]headData := make([]byte, dp.GetHeadLen())_, err := io.ReadFull(conn, headData)if err != nil {fmt.Println("read head err ", err)return}//解析headDatamsgHead, err := dp.UnPack(headData)if err != nil {fmt.Println("server unpack err ", err)return}if msgHead.GetMsgLen() > 0 {//msg中是有数据的，需要进行第二次读取//②第二次读取，是根据head中的dataLen来读取data内容msg := msgHead.(*Message)//根据数据包中的数据长度创建对应的切片msg.Data = make([]byte, msg.GetMsgLen())_, err := io.ReadFull(conn, msg.Data)if err != nil {fmt.Println("server unpack err ", err)return}//完整的一个消息已经读取完毕fmt.Println("----->Receive MsgID:", msg.Id, "dataLen=", msg.DataLen, ",/data=", string(msg.Data))}}}(conn)}()/*模拟客户端发送数据包*/conn, err := net.Dial("tcp", "127.0.0.1:7777")if err != nil {fmt.Println("client dial err ", err)return}//创建一个封包对象dp := NewDataPack()//模拟粘包过程，封装两个msg一同发送msg1 := &Message{Id:      1,DataLen: 4,Data:    []byte{'z', 'i', 'n', 'x'},}msg2 := &Message{Id:      2,DataLen: 8,Data:    []byte{'h', 'e', 'l', 'l', 'o', ' ', 'y', 'a'},}//将两个数据包粘在一起[将数据进行打包],打包最后的结果还是一个[]byte切片sendData1, err := dp.Pack(msg1)if err != nil {fmt.Println("Client pack msg1 err ", err)return}sendData2, err := dp.Pack(msg2)if err != nil {fmt.Println("Client pack msg2 err ", err)return}//需要使用sendData2，将数据打散，否则会成为切片中嵌套切片sendData1 = append(sendData1, sendData2...)//一次性将全部数据发送给服务端conn.Write(sendData1)//阻塞，查看控制台打印结果是否正确select {}
}

2.3 zinx框架集成消息封装机制

将消息封装机制集成到我们自定义的zinx框架中

• 将zinx/znet/connection.go中的StartReader方法使用封装后的消息实现
  

• 将zinx/znet/request.go中的data改为IMessage
• 在zinx/znet/message.go中添加一个NewMessage的方法
• 在zinx/znet/connection.go中新增SendMsg方法

①zinx/ziface/iconnection.go

package zifaceimport "net"type IConnection interface {//启动连接Start()//停止连接Stop()//获取当前连接的Conn对象GetTCPConnection() *net.TCPConn//获取当前连接模块的idGetConnectionID() uint32//获取远程客户端的TCP状态 IP：PortRemoteAddr() net.Addr//发送数据SendMsg(msgId uint32, data []byte) error
}//定义一个处理连接业务的方法
type HandleFunc func(*net.TCPConn, []byte, int) error

②zinx/znet/connection.go

package znetimport ("fmt""github.com/kataras/iris/v12/x/errors""io""myTest/zinx/ziface""net"
)type Connection struct {Conn     *net.TCPConnConnID   uint32isClosed bool//告知当前的连接已经退出ExitChan chan boolRouter   ziface.IRouter
}func NewConnection(conn *net.TCPConn, connID uint32, router ziface.IRouter) *Connection {c := &Connection{Conn:     conn,ConnID:   connID,Router:   router,isClosed: false,ExitChan: make(chan bool, 1),}return c
}func (c *Connection) StartReader() {fmt.Println("reader goroutine is running...")defer fmt.Println("connID=", c.ConnID, "Reader is exit, remote addr is ", c.RemoteAddr().String())defer c.Stop()//读取数据for {//buf := make([]byte, util.GlobalObject.MaxPackageSize)//_, err := c.Conn.Read(buf)//if err != nil {//	fmt.Printf("connID %d receive buf err %s\n", c.ConnID, err)//	continue//}//创建一个拆包对象dp := NewDataPack()//读取客户端的msg Head 二进制流 8字节headData := make([]byte, dp.GetHeadLen())if _, err := io.ReadFull(c.GetTCPConnection(), headData); err != nil {fmt.Println("read msg head err ", err)break}//拆包，将读取到的headData封装为msgmsg, err := dp.UnPack(headData)if err != nil {fmt.Println("unpack msg err ", err)break}//根据dataLen，再次读取Data，放在msg.Data中，var data []byte//如果数据包中有数据，则读取if msg.GetMsgLen() > 0 {data = make([]byte, msg.GetMsgLen())//将切片data读满if _, err := io.ReadFull(c.GetTCPConnection(), data); err != nil {fmt.Println("read msg data err ", err)break}}msg.SetData(data)//封装请求，改为router处理r := Request{conn: c.Conn,msg:  msg,}go func(request ziface.IRequest) {c.Router.PreHandle(request)c.Router.Handler(request)c.Router.PostHandler(request)}(&r)}
}//启动连接
func (c *Connection) Start() {fmt.Printf("ConnID %d is Start...", c.ConnID)go c.StartReader()
}//停止连接
func (c *Connection) Stop() {fmt.Println("Connection Stop()...ConnectionID = ", c.ConnID)if c.isClosed {return}c.isClosed = truec.Conn.Close()close(c.ExitChan)
}//获取当前连接的Conn对象
func (c *Connection) GetTCPConnection() *net.TCPConn {return c.Conn
}//获取当前连接模块的id
func (c *Connection) GetConnectionID() uint32 {return c.ConnID
}//获取远程客户端的TCP状态 IP：Port
func (c *Connection) RemoteAddr() net.Addr {return c.Conn.RemoteAddr()
}//发送数据
func (c *Connection) SendMsg(msgId uint32, data []byte) error {if c.isClosed {return errors.New("connection closed\n")}//将data进行封包dp := NewDataPack()binaryMsg, err := dp.Pack(NewMessage(msgId, data))if err != nil {fmt.Println("Pack error msg id=", msgId)return errors.New("pack error msg")}//将数据发送给客户端if _, err := c.Conn.Write(binaryMsg); err != nil {fmt.Println("write msg id ", msgId, " error ", err)return errors.New("conn write err ")}return nil
}

2.4 zinx测试集成消息封装机制

注意：之前irequest.go和request.go代码有误，修改为以下即可

• 修改部分主要为：将GetConnection更换为我们自定义的connection

/zinx/ziface/irequest.go:

package zifacetype IRequest interface {GetConnection() IConnectionGetData() []byteGetMsgID() uint32
}

/zinx/znet/request.go:

package znetimport ("myTest/zinx/ziface"
)type Request struct {conn ziface.IConnectionmsg  ziface.IMessage
}func (r *Request) GetConnection() ziface.IConnection {return r.conn
}func (r *Request) GetData() []byte {return r.msg.GetMsgData()
}func (r *Request) GetMsgID() uint32 {return r.msg.GetMsdId()
}

①client.go

package mainimport ("fmt""io""myTest/zinx/znet""net""time"
)/*
模拟客户端
*/
func main() {fmt.Println("client start...")time.Sleep(time.Second * 1)//1 创建服务器连接conn, err := net.Dial("tcp", "127.0.0.1:8092")if err != nil {fmt.Println("client start err ", err)return}for {//发送封装后的数据包dp := znet.NewDataPack()binaryMsg, err := dp.Pack(znet.NewMessage(0, []byte("Zinx v0.5 client test msg")))if err != nil {fmt.Println("client pack msg err ", err)return}if _, err := conn.Write(binaryMsg); err != nil {fmt.Println("client write err ", err)return}//服务器应该给我们回复一个message数据，msgId为1，内容为ping...ping...//1 先读取流中的head部分，得到Id和dataLenbinaryHead := make([]byte, dp.GetHeadLen())if _, err := io.ReadFull(conn, binaryHead); err != nil {fmt.Println("client read head err ", err)break}//将二进制的head拆包到msg中msgHead, err := dp.UnPack(binaryHead)if err != nil {fmt.Println("client unpack msgHead err ", err)break}if msgHead.GetMsgLen() > 0 {//2 有数据, 再根据dataLen进行二次读取，将data读出来msg := msgHead.(*znet.Message)msg.Data = make([]byte, msg.GetMsgLen())if _, err := io.ReadFull(conn, msg.Data); err != nil {fmt.Println("read msg data error ", err)return}fmt.Println("--------> Receive Server msg , ID=", msg.Id, " ,len=", msg.DataLen, " ,data=", string(msg.Data))}//cpu阻塞，让出cpu时间片，避免无限for循环导致其他程序无法获取cpu时间片time.Sleep(time.Second * 1)}
}

②server.go

package mainimport ("fmt""myTest/zinx/ziface""myTest/zinx/znet"
)//自定义一个Router，测试路由功能
type PingRouter struct {znet.BaseRouter
}func (pr *PingRouter) Handler(request ziface.IRequest) {fmt.Println("call router handler...")//先读取客户端数据，再回写ping...ping...ping...fmt.Println("receive from client msgId=", request.GetMsgID(),"data=", string(request.GetData()))//回写pingerr := request.GetConnection().SendMsg(1, []byte("ping...ping...ping..."))if err != nil {fmt.Println(err)}
}func main() {s := znet.NewServer("[Zinx v5.0]")//添加自定义路由router := &PingRouter{}s.AddRouter(router)s.Serve()
}

测试结果：

2.5 消息管理模块（支持多路由）MsgHandler

①zinx/ziface/imsgHandler.go

package zifacetype IMsgHandler interface {DoMsgHandler(request IRequest)AddRouter(msgId uint32, router IRouter)
}

②zinx/znet/msgHandler.go

package znetimport ("fmt""myTest/zinx/ziface""strconv"
)type MsgHandle struct {//msgId与对应的router对应Api map[uint32]ziface.IRouter
}func NewMsgHandle() *MsgHandle {return &MsgHandle{Api: make(map[uint32]ziface.IRouter),}
}func (mh *MsgHandle) DoMsgHandler(request ziface.IRequest) {//判断是否有对应的routerif _, ok := mh.Api[request.GetMsgID()]; !ok {fmt.Println("msgId ", request.GetMsgID(), "does not exist handler, need to add router")return}//call handlerrouter := mh.Api[request.GetMsgID()]router.PreHandle(request)router.Handler(request)router.PostHandler(request)
}func (mh *MsgHandle) AddRouter(msgId uint32, router ziface.IRouter) {if _, ok := mh.Api[msgId]; ok {//如果已经存在了对应的router，则提示panic("repeat api, msgId = " + strconv.Itoa(int(msgId)))}mh.Api[msgId] = routerfmt.Println("msgId ", msgId, "Add router success ")
}

2.6 消息管理模块集成到Zinx框架中[V0.6]

1. 将server模块中的Router属性替换为MsgHandler
2. 将server之前的AddRouter修改为调用MsgHandler的AddRouter
3. 将connection模块中的Router属性修改为MsgHandler
4. Connection中之前调度Router的业务替换为MsgHandler调度

测试结果：

Zinx正确接受了不同客户端的请求，并根据不同的请求做出了不同的处理

• 根据msgId和注册handler来对应处理不同请求
