使用来自网络的原始字节

可行的方法是使用编码/二进制，它内部完成了您上面编写的大部分工作。

（游乐场）

package mainimport (    "bytes"    "encoding/binary"    "fmt"    "log")type Header struct {    Length uint16    Size   uint16    Flags  uint32}func main() {    header := &Header{Length: 0xC8, Size: 3, Flags: 0x100}    fmt.Printf("in = %#vn", header)    buf := new(bytes.Buffer)    err := binary.Write(buf, binary.LittleEndian, header)    if err != nil {        log.Fatalf("binary.Write failed: %v", err)    }    b := buf.Bytes()    fmt.Printf("wire = % xn", b)    var header2 Header    buf2 := bytes.NewReader(b)    err = binary.Read(buf2, binary.LittleEndian, &header2)    if err != nil {        log.Fatalf("binary.Read failed: %v", err)    }    fmt.Printf("out = %#vn", header2)}

哪些印刷品

in = &main.Header{Length:0xc8, Size:0x3, Flags:0x100}wire = c8 00 03 00 00 01 00 00out = main.Header{Length:0xc8, Size:0x3, Flags:0x100}
