10.3 链接属性Zinx-V0.10单元测试

那么，接下来，我们简单测试一下链接属性的设置与提取是否可用。

Server.go

package main

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

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

//Ping 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()))

    err := request.GetConnection().SendBuffMsg(0, []byte("ping...ping...ping"))
    if err != nil {
        fmt.Println(err)
    }
}

type HelloZinxRouter struct {
    znet.BaseRouter
}

//HelloZinxRouter Handle
func (this *HelloZinxRouter) Handle(request ziface.IRequest) {
    fmt.Println("Call HelloZinxRouter 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()))

    err := request.GetConnection().SendBuffMsg(1, []byte("Hello Zinx Router V0.10"))
    if err != nil {
        fmt.Println(err)
    }
}

//创建连接的时候执行
func DoConnectionBegin(conn ziface.IConnection) {
    fmt.Println("DoConnecionBegin is Called ... ")

    //=============设置两个链接属性，在连接创建之后===========
    fmt.Println("Set conn Name, Home done!")
    conn.SetProperty("Name", "Aceld")
    conn.SetProperty("Home", "https://www.jianshu.com/u/35261429b7f1")
    //===================================================

    err := conn.SendMsg(2, []byte("DoConnection BEGIN..."))
    if err != nil {
        fmt.Println(err)
    }
}

//连接断开的时候执行
func DoConnectionLost(conn ziface.IConnection) {
    //============在连接销毁之前，查询conn的Name，Home属性=====
    if name, err:= conn.GetProperty("Name"); err == nil {
        fmt.Println("Conn Property Name = ", name)
    }

    if home, err := conn.GetProperty("Home"); err == nil {
        fmt.Println("Conn Property Home = ", home)
    }
    //===================================================

    fmt.Println("DoConneciotnLost is Called ... ")
}

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

    //注册链接hook回调函数
    s.SetOnConnStart(DoConnectionBegin)
    s.SetOnConnStop(DoConnectionLost)

    //配置路由
    s.AddRouter(0, &PingRouter{})
    s.AddRouter(1, &HelloZinxRouter{})

    //开启服务
    s.Serve()
}

这里主要看DoConnectionBegin()和DoConnectionLost()两个函数的实现， 利用在两个Hook函数中，设置链接属性和提取链接属性。链接创建之后给当前链接绑定两个属性"Name","Home", 那么我们在随时可以通过conn.GetProperty()方法得到链接已经设置的属性。

$go run Server.go

$go run Client0.go

服务端：

$ go run Server.go

127.0.0.1:55208 [conn Reader exit!]

客户端：

$ go run Client0.go 
Client Test ... start

==> Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
==> Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
^Csignal: interrupt

当我们终止客户端链接，那么服务端在断开链接之前，已经读取到了conn的两个属性Name和Home
