Go 将uint8的类型转换为unit32


原文链接: Go 将uint8的类型转换为unit32

package main

import (

"encoding/binary"
"fmt"

)

func main() {

u8 := []uint8{0, 1, 2, 3}
u32LE := binary.LittleEndian.Uint32(u8)
fmt.Println("little-endian:", u8, "to", u32LE)
u32BE := binary.BigEndian.Uint32(u8)
fmt.Println("big-endian:   ", u8, "to", u32BE)

}

输出:

little-endian: [0 1 2 3] to 50462976
big-endian: [0 1 2 3] to 66051

Go 二进制包函数被实现为一系列的转换。

func (littleEndian) Uint32(b []byte) uint32 {

return uint32(b[0]) | uint32(b[1])<<8 | uint32(b[2])<<16 | uint32(b[3])<<24

}

func (bigEndian) Uint32(b []byte) uint32 {

return uint32(b[3]) | uint32(b[2])<<8 | uint32(b[1])<<16 | uint32(b[0])<<24

}
