将uint32的字节附加到字节片吗？

Question

If I have an existing []byte, what is the recommended way to append the bytes of one or more uint32 value(s) to it?

For example, what should I replace // ??? with:

s := []byte{0x00, 0x01, 0x02, 0x03}

u := uint32(0x07060504)
// ???

fmt.Println(s)  // Should print [0 1 2 3 4 5 6 7]

Edit: One option would be s = append(s, byte(u)); s = append(s, byte(u >> 8)); s = append(s, byte(u >> 16)); s = append(s, byte(u >> 24)), but is there a more idiomatic way to do this? Perhaps using package binary and/or package bytes?

Answer 1

encoding/binary has the functions you need:

import "encoding/binary"

b := make([]byte,4)
binary.LittleEndian.PutUint32(b, u)
s = append(s, b)
