func Byte8 ¶
Byte8 将给定的切片转换为[8]byte类型
说明： 使用copy(to,from)函数自由填充目标切片或数组，如：
n:=copy(arr,slice) 或
n:=copy(slice,arr)
Example ¶
fmt.Println(Byte8([]byte{'a', 'b', 'c'}))
fmt.Println(Byte8([]byte{1, 2, 3, 4, 5, 6, 7, 8, 9}))
// out:
// [97 98 99 0 0 0 0 0]
// [1 2 3 4 5 6 7 8]
Output:

func StructToMap(obj interface{}) map[string]interface{}
StructToMap struct convert to map
func ToBool ¶
ToBool 将字符串转换为bool类型，参数错误时返回false
1,t,T,TRUE, true, True => true 0,f,F,FALSE,false,False => false
