5.4 使用Zinx-V0.5完成应用程序

现在我们可以基于Zinx框架完成发送msg功能的测试用例了。

Server.go

package main

import (
    "fmt"
    "zinx/ziface"
    "zinx/znet"
)

//ping test 自定义路由
type PingRouter struct {
    znet.BaseRouter
}

//Test Handle
func (this *PingRouter) Handle(request ziface.IRequest) {
    fmt.Println("Call PingRouter Handle")
    //先读取客户端的数据,再回写ping...ping...ping
    fmt.Println("recv from client : msgId=", request.GetMsgID(), ", data=", string(request.GetData()))

    //回写数据
    err := request.GetConnection().SendMsg(1, []byte("ping...ping...ping"))
    if err != nil {
        fmt.Println(err)
    }
}

func main() {
    //创建一个server句柄
    s := znet.NewServer()

    //配置路由
    s.AddRouter(&PingRouter{})

    //开启服务
    s.Serve()
}

当前Server端是先把客户端发送来Msg解析,然后返回一个MsgId为1的消息,消息内容是"ping...ping...ping"

Client.go

package main

import (
    "fmt"
    "io"
    "net"
    "time"
    "zinx/znet"
)

/*
    模拟客户端
 */
func main() {

    fmt.Println("Client Test ... start")
    //3秒之后发起测试请求,给服务端开启服务的机会
    time.Sleep(3 * time.Second)

    conn,err := net.Dial("tcp", "127.0.0.1:7777")
    if err != nil {
        fmt.Println("client start err, exit!")
        return
    }

    for {
        //发封包message消息
        dp := znet.NewDataPack()
        msg, _ := dp.Pack(znet.NewMsgPackage(0,[]byte("Zinx V0.5 Client Test Message")))
        _, err := conn.Write(msg)
        if err !=nil {
            fmt.Println("write error err ", err)
            return
        }

        //先读出流中的head部分
        headData := make([]byte, dp.GetHeadLen())
        _, err = io.ReadFull(conn, headData) //ReadFull 会把msg填充满为止
        if err != nil {
            fmt.Println("read head error")
            break
        }
        //将headData字节流 拆包到msg中
        msgHead, err := dp.Unpack(headData)
        if err != nil {
            fmt.Println("server unpack err:", err)
            return
        }

        if msgHead.GetDataLen() > 0 {
            //msg 是有data数据的,需要再次读取data数据
            msg := msgHead.(*znet.Message)
            msg.Data = make([]byte, msg.GetDataLen())

            //根据dataLen从io中读取字节流
            _, err := io.ReadFull(conn, msg.Data)
            if err != nil {
                fmt.Println("server unpack data err:", err)
                return
            }

            fmt.Println("==> Recv Msg: ID=", msg.Id, ", len=", msg.DataLen, ", data=", string(msg.Data))
        }

        time.Sleep(1*time.Second)
    }
}

这里Client客户端,模拟了一个MsgId为0的"Zinx V0.5 Client Test Message"消息,然后把服务端返回的数据打印出来。

我们分别在两个终端运行

$go run Server.go
$go run Client.go

服务端结果:

$ go run Server.go 
Add Router succ! 
[START] Server name: zinx v-0.5 demoApp,listenner at IP: 127.0.0.1, Port 7777 is starting
[Zinx] Version: V0.4, MaxConn: 3, MaxPacketSize: 4096
start Zinx server   zinx v-0.5 demoApp  succ, now listenning...
Reader Goroutine is  running
Call PingRouter Handle
recv from client : msgId= 0 , data= Zinx V0.5 Client Test Message
Call PingRouter Handle
recv from client : msgId= 0 , data= Zinx V0.5 Client Test Message
Call PingRouter Handle
recv from client : msgId= 0 , data= Zinx V0.5 Client Test Message
...

客户端结果:

$ go run Client.go 
Client Test ... start
==> Recv Msg: ID= 1 , len= 18 , data= ping...ping...ping
==> Recv Msg: ID= 1 , len= 18 , data= ping...ping...ping
==> Recv Msg: ID= 1 , len= 18 , data= ping...ping...ping
...

好了,我们的Zinx已经成功的集成消息的封装功能了,这样我们就有Zinx的通信的基本协议标准了。
