Got it working \o. 我必须正确处理字节范围。苹果的软件使用范围功能，所以我必须满足它的需求:)。这是我在GolangGIN中的REST API函数。

func AudioGet(c *gin.Context) {

// Typ połączania
c.Header("Access-Control-Allow-Origin", "*")
c.Header("Connection", "Keep-Alive")
c.Header("Transfer-Encoding", "identity")
c.Header("Accept-Ranges", "bytes")

// Odczytujemy parametr - numer muzy
id := c.Param("id")
filenameWAV := cacheDir + id + ".wav"

var size int64
if fileExists(filenameWAV) {
    s, err := fileSize(filenameWAV)
    if ErrCheck(err) {
        log.Println("[GIN:AudioGet] Size of file " + filenameWAV + " = " + strconv.Itoa(int(s)))
        size = s
    } else {
        log.Println("[GIN:AudioGet] Can't read size of file " + filenameWAV)
        c.JSON(http.StatusInternalServerError, "Can't read size of file")
        return
    }
} else {
    log.Println("[GIN:AudioGet] No WAV file " + filenameWAV)
    c.JSON(http.StatusInternalServerError, "No WAV file")
    return
}

bytesToSend := 0
bytesToSendStart := 0
bytesToSendEnd := 0
headerRange := c.GetHeader("Range")
log.Println("[GIN:AudioGet2] Header:Range = " + headerRange)
if len(headerRange) > 0 {
    headerRangeSplitted1 := strings.Split(headerRange, "=")

    if len(headerRangeSplitted1) > 0 {
        log.Println("[GIN:AudioGet2] range in " + headerRangeSplitted1[0])

        if len(headerRangeSplitted1) > 1 {
            headerRangeSplitted2 := strings.Split(headerRangeSplitted1[1], "-")
            if len(headerRangeSplitted2) > 0 {
                log.Println("[GIN:AudioGet2] start = " + headerRangeSplitted2[0])
                if len(headerRangeSplitted2) > 1 {
                    log.Println("[GIN:AudioGet2] end = " + headerRangeSplitted2[1])
                    bytesToSendStart, err := strconv.Atoi(headerRangeSplitted2[0])
                    if ErrCheck2(err) {
                        bytesToSendEnd, err := strconv.Atoi(headerRangeSplitted2[1])
                        if ErrCheck2(err) {
                            bytesToSend = bytesToSendEnd - bytesToSendStart + 1
                        }
                    }
                }
            }
        }
    }
}

log.Println("[GIN:AudioGet2] Bytes to send " + strconv.Itoa(bytesToSend))
log.Println("[GIN:AudioGet2] From " + strconv.Itoa(bytesToSendStart) + " to " + strconv.Itoa(bytesToSendEnd))

if bytesToSend > 0 {
    c.Header("Content-length", strconv.Itoa(bytesToSend))
    c.Header("Content-range", "bytes "+strconv.Itoa(bytesToSendStart)+"-"+strconv.Itoa(bytesToSendEnd)+"/"+strconv.Itoa(int(size)))
    size = int64(bytesToSend)
}

// Streaming LOOP...

// Otwieraamy plik - bez sprawdzania błędów
file, err := os.Open(filenameWAV)
defer file.Close()
if ErrCheck(err) {
    // Info o wejściu do GET
    log.Println("[GIN:AudioGet] Sending " + id + "...")

    p := make([]byte, size)
    file.ReadAt(p, int64(bytesToSendStart))
    file.Close()
    if bytesToSend > 0 {
        c.Data(http.StatusPartialContent, "audio/wav", p)
    } else {
        c.Data(http.StatusOK, "audio/wav", p)
    }
} else {
    log.Println("[GIN:AudioGet] Can't open file " + filenameWAV)
}

}

所以，你可以看到苹果浏览器要求先输入两个字节，然后是64kB，然后再输入其余的音乐文件。
