int,int16与[]byte之间的转换

//整形转换成字节

func IntToBytes(n int) []byte {
  x := int32(n)
  bytesBuffer := bytes.NewBuffer([]byte{})
  binary.Write(bytesBuffer, binary.BigEndian, x)
  return bytesBuffer.Bytes()
}

//字节转换成整形

func BytesToInt(b []byte) int {
  bytesBuffer := bytes.NewBuffer(b)

  var x int32
  binary.Read(bytesBuffer, binary.BigEndian, &x)

  return int(x)
}
