Parsing binary.Read（）未在结构中生成预期值

我正在尝试制作一个MOBI文件解析器，但在尝试使用binary.Read（）将一些二进制文件解析为结构时遇到了一些问题

我认为这是一个对齐问题，但我不知道为什么我没有得到预期的值。我通过libmobi运行了.mobi文件来测试代码的输出，并检查了.mobi的二进制文件，以验证我没有发疯，libmobi代码没有做奇怪的事情（事实并非如此）

下面是一个简单的例子：

package main

import (
    "bytes"
    "encoding/binary"
    "fmt"
)

type Header struct {
    Type        [4]byte
    Creator     [4]byte
    Uid         uint32
    Next        uint32
    RecordCount uint16
}

func main() {
    testBytes := []byte{66, 79, 79, 75, 77, 79, 66, 73, 0, 0, 1, 17, 0, 0, 0, 0, 0, 136}

    h := Header{}
    buf := bytes.NewBuffer(testBytes)
    binary.Read(buf, binary.LittleEndian, &h)

    fmt.Printf("%s\n", h.Type)    // BOOK, as expected
    fmt.Printf("%s\n", h.Creator) // MOBI, as expected
    fmt.Printf("%d\n", h.Next)    // 0, as expected

    fmt.Printf("%d\n", h.Uid)
    // expecting Uid to be 273, but it's 285278208...
    fmt.Printf("%d\n", h.RecordCount)
    // expecting RecordCount to be 136, but it's 34816...
}

任何帮助都将不胜感激

编辑：以下是在

book.mobi

上执行

xxd

操作的十六进制字节：

是的，BigEndian的效果更好

package main

import (
    "bytes"
    "encoding/binary"
    "fmt"
)

type Header struct {
    Type        [4]byte
    Creator     [4]byte
    Uid         uint32
    Next        uint32
    RecordCount uint16
}

func main() {
    testBytes := []byte{66, 79, 79, 75, 77, 79, 66, 73, 0, 0, 1, 17, 0, 0, 0, 0, 0, 136}

    h := Header{}
    buf := bytes.NewBuffer(testBytes)
    binary.Read(buf, binary.BigEndian, &h)

    fmt.Printf("%s\n", h.Type)    // BOOK, as expected
    fmt.Printf("%s\n", h.Creator) // MOBI, as expected
    fmt.Printf("%d\n", h.Next)    // 0, as expected

    fmt.Printf("%d\n", h.Uid)
    // expecting Uid to be 273, but it's 285278208...
    fmt.Printf("%d\n", h.RecordCount)
    // expecting RecordCount to be 136, but it's 34816...
}

您的

testBytes

数字是大端数字。你为什么期望小endian值？啊，哇。非常感谢。我知道我离问题太近了，错过了一些简单的东西
