Go異步check簡單示例

 

 

異步check代碼：

package main

import (
	"fmt"
	"reflect"
	"time"
)

type janitor struct {
	interval time.Duration
	overtime time.Duration
}


func (j *janitor) Runasyncheck(f interface{}, params ...interface{}) {
	//fmt.Println(params)
	//創建週期斷續器
	ticker := time.NewTicker(j.interval)
	//創建定時器
	timer := time.NewTimer(j.overtime)
	loop:
		for {
			select {
			case <-timer.C: //當Timer每次到達設置的時間時就會向管道發送消息，此時超時退出
				print("超時\n")
				break loop
			case <-ticker.C: //當Ticker每次到達設置的時間時就會向管道發送消息，此時進行異步check操作
				//print("異步check\n")
				fv := reflect.ValueOf(f)
				realParams := make([]reflect.Value, len(params)) //參數
				for i, item := range params {
					realParams[i] = reflect.ValueOf(item)
				}
				fv.Call(realParams)
			}
		}
	fmt.Println("Break")
}

測試：

package main

import (
	"fmt"
	"time"
	"testing"
)
func hello1() {
	fmt.Println("123")
}

func hello2(i string) {
	fmt.Println(i)
}
func Test_main(t *testing.T){
	j := &janitor{
		interval: time.Second,
		overtime:5*time.Second,
	}
	j.Runasyncheck(hello1)
	j.Runasyncheck(hello2,"23")

}
