ok, kebanyakan dari mereka telah menunjukkan Anda sesuatu yang baik. Biarkan saya memberi Anda ini:
// ToString Change arg to string
func ToString(arg interface{}, timeFormat ...string) string {
if len(timeFormat) > 1 {
log.SetFlags(log.Llongfile | log.LstdFlags)
log.Println(errors.New(fmt.Sprintf("timeFormat's length should be one")))
}
var tmp = reflect.Indirect(reflect.ValueOf(arg)).Interface()
switch v := tmp.(type) {
case int:
return strconv.Itoa(v)
case int8:
return strconv.FormatInt(int64(v), 10)
case int16:
return strconv.FormatInt(int64(v), 10)
case int32:
return strconv.FormatInt(int64(v), 10)
case int64:
return strconv.FormatInt(v, 10)
case string:
return v
case float32:
return strconv.FormatFloat(float64(v), 'f', -1, 32)
case float64:
return strconv.FormatFloat(v, 'f', -1, 64)
case time.Time:
if len(timeFormat) == 1 {
return v.Format(timeFormat[0])
}
return v.Format("2006-01-02 15:04:05")
case jsoncrack.Time:
if len(timeFormat) == 1 {
return v.Time().Format(timeFormat[0])
}
return v.Time().Format("2006-01-02 15:04:05")
case fmt.Stringer:
return v.String()
case reflect.Value:
return ToString(v.Interface(), timeFormat...)
default:
return ""
}
}
