Go异步check简单示例

异步check代码：

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)
    //创建周期断续器
    ticker := time.NewTicker(j.interval)
    //创建定时器
    timer := time.NewTimer(j.overtime)
    loop:
        for {
            select {
            case <-timer.C: //当Timer每次到达设置的时间时就会向管道发送消息，此时超时退出
                print("超时\n")
                break loop
            case <-ticker.C: //当Ticker每次到达设置的时间时就会向管道发送消息，此时进行异步check操作
                //print("异步check\n")
                fv := reflect.ValueOf(f)
                realParams := make([]reflect.Value, len(params)) //参数
                for i, item := range params {
                    realParams[i] = reflect.ValueOf(item)
                }
                fv.Call(realParams)
            }
        }
    fmt.Println("Break")
}

测试：

package main<br>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")
 
}
