解决Go语言time包数字与时间相乘的问题

package main
import "time"
func main(){
    connectTimeout := 10
    time.Sleep(time.Second*connectTimeout)
}

seconds := 10
	ctx, cancel := context.WithTimeout(context.Background(), time.Duration(seconds) * time.Second)
	//ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

// Common durations. There is no definition for units of Day or larger
// to avoid confusion across daylight savings time zone transitions.
//
// To count the number of units in a Duration, divide:
//	second := time.Second
//	fmt.Print(int64(second/time.Millisecond)) // prints 1000
//
// To convert an integer number of units to a Duration, multiply:
//	seconds := 10
//	fmt.Print(time.Duration(seconds)*time.Second) // prints 10s

  idc := getIdc()
    var idcTimeOut int64
    if _, ok := IdcTimeout[idc]; ok {
        idcTimeOut = IdcTimeout[idc]
    } else {
        idcTimeOut = AllTimeout
    }
    //错误写法
    time.After(time.Millisecond * idcTimeOut
    //正确写法
    time.After(time.Millisecond * time.Duration(idcTimeOut))
