golang interface{}类型转换的实现示例

func TpyeTransfer(value interface{}) (typ int, val interface{}) {

	switch value.(type) {

	case int:
		return 6, float32(value.(int))
	case bool:
		return 3, value.(bool)
	case int8:
		return 6, float32(value.(int8))
	case int16:
		return 6, float32(value.(int16))
	case int32:
		return 6, float32(value.(int32))
	case uint8:
		return 6, float32(value.(uint8))
	case uint16:
		return 6, float32(value.(uint16))
	case uint32:
		return 6, float32(value.(uint32))
	case float32:
		return 6, float32(value.(float32))

	case string:
		fmt.Printf("data type string is %T \n", value)
		return 0, value

	case int64:
		return 10, float64(value.(int64))
	case float64:
		return 10, float64(value.(float64))
	case uint64:
		return 10, float64(value.(uint64))

	default:

		fmt.Printf("data type is:%T \n", value)
		return 0, value

	}
