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

  1. package main
  3. import (
  4.     "fmt"
  5.     "zinx/ziface"
  6.     "zinx/znet"
  7. )
  9. //ping test 自定义路由
  10. type PingRouter struct {
  11.     znet.BaseRouter
  12. }
  14. //Ping Handle
  15. func (this *PingRouter) Handle(request ziface.IRequest) {
  16.     fmt.Println("Call PingRouter Handle")
  17.     //先读取客户端的数据，再回写ping...ping...ping
  18.     fmt.Println("recv from client : msgId=", request.GetMsgID(), ", data=", string(request.GetData()))
  20.     err := request.GetConnection().SendBuffMsg(0, []byte("ping...ping...ping"))
  21.     if err != nil {
  22.         fmt.Println(err)
  23.     }
  24. }
  26. type HelloZinxRouter struct {
  27.     znet.BaseRouter
  28. }
  30. //HelloZinxRouter Handle
  31. func (this *HelloZinxRouter) Handle(request ziface.IRequest) {
  32.     fmt.Println("Call HelloZinxRouter Handle")
  33.     //先读取客户端的数据，再回写ping...ping...ping
  34.     fmt.Println("recv from client : msgId=", request.GetMsgID(), ", data=", string(request.GetData()))
  36.     err := request.GetConnection().SendBuffMsg(1, []byte("Hello Zinx Router V0.10"))
  37.     if err != nil {
  38.         fmt.Println(err)
  39.     }
  40. }
  42. //创建连接的时候执行
  43. func DoConnectionBegin(conn ziface.IConnection) {
  44.     fmt.Println("DoConnecionBegin is Called ... ")
  46.     //=============设置两个链接属性，在连接创建之后===========
  47.     fmt.Println("Set conn Name, Home done!")
  48.     conn.SetProperty("Name", "Aceld")
  49.     conn.SetProperty("Home", "https://www.jianshu.com/u/35261429b7f1")
  50.     //===================================================
  52.     err := conn.SendMsg(2, []byte("DoConnection BEGIN..."))
  53.     if err != nil {
  54.         fmt.Println(err)
  55.     }
  56. }
  58. //连接断开的时候执行
  59. func DoConnectionLost(conn ziface.IConnection) {
  60.     //============在连接销毁之前，查询conn的Name，Home属性=====
  61.     if name, err:= conn.GetProperty("Name"); err == nil {
  62.         fmt.Println("Conn Property Name = ", name)
  63.     }
  65.     if home, err := conn.GetProperty("Home"); err == nil {
  66.         fmt.Println("Conn Property Home = ", home)
  67.     }
  68.     //===================================================
  70.     fmt.Println("DoConneciotnLost is Called ... ")
  71. }
  73. func main() {
  74.     //创建一个server句柄
  75.     s := znet.NewServer()
  77.     //注册链接hook回调函数
  78.     s.SetOnConnStart(DoConnectionBegin)
  79.     s.SetOnConnStop(DoConnectionLost)
  81.     //配置路由
  82.     s.AddRouter(0, &PingRouter{})
  83.     s.AddRouter(1, &HelloZinxRouter{})
  85.     //开启服务
  86.     s.Serve()
  87. }

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。

  1. $go run Server.go
  1. $go run Client0.go

服务端：

  1. $ go run Server.go 
  2. Add api msgId =  0
  3. Add api msgId =  1
  4. [START] Server name: zinx v-0.10 demoApp,listenner at IP: 127.0.0.1, Port 7777 is starting

  20. Set conn Name, Home done!
  21. [Writer Goroutine is running]
  22. [Reader Goroutine is running]
  23. Add ConnID= 0  request msgID= 0 to workerID= 0
  24. Call PingRouter Handle
  25. recv from client : msgId= 0 , data= Zinx V0.8 Client0 Test Message
  26. Add ConnID= 0  request msgID= 0 to workerID= 0
  27. Call PingRouter Handle
  28. recv from client : msgId= 0 , data= Zinx V0.8 Client0 Test Message
  29. Add ConnID= 0  request msgID= 0 to workerID= 0
  30. Call PingRouter Handle
  31. recv from client : msgId= 0 , data= Zinx V0.8 Client0 Test Message
  32. read msg head error  read tcp4 127.0.0.1:7777->127.0.0.1:55208: read: connection reset by peer
  33. Conn Stop()...ConnID =  0
  34. ---> CallOnConnStop....
  35. Conn Property Name =  Aceld
  36. Conn Property Home =  https://www.jianshu.com/u/35261429b7f1

  38. connection Remove ConnID= 0  successfully: conn num =  0
  39. 127.0.0.1:55208 [conn Reader exit!]
  40. 127.0.0.1:55208 [conn Writer exit!]

客户端：

  1. $ go run Client0.go 
  2. Client Test ... start
  3. ==> Recv Msg: ID= 2 , len= 21 , data= DoConnection BEGIN...
  4. ==> Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
  5. ==> Recv Msg: ID= 0 , len= 18 , data= ping...ping...ping
  6. ^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
