设置 apache 在请求 MP3 文件时为 PHP 提供服务

问题描述

我正在研究一种通过 PHP 提供 MP3 文件的方法，经过一些帮助形成如此庞大的文件，我让它工作了这里

I'm working on a way to serve up MP3 files through PHP and after some help form the SO massive, I got it working here

但是，当我将它用作这样的音频标签中的源时，该示例似乎不起作用

However, that example doesn't appear to work when I use it as the source in an audio tag like this

<html>
    <head>
        <title>Audio Tag Experiment</title>
    </head>
    <body>

    <audio id='audio-element' src="music/mp3.php" autoplay controls>
    Your browser does not support the audio element.
    </audio>

    </body>
</html>

这里是 PHP

<?php

$track = "lilly.mp3";

if(file_exists($track))
{
header("Content-Transfer-Encoding: binary"); 
header("Content-Type: audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3");
header('Content-length: ' . filesize($track));
header('Content-Disposition: filename="lilly.mp3"');
header('X-Pad: avoid browser bug');
Header('Cache-Control: no-cache');

readfile($track);
}else{
    echo "no file";
}

所以我在想(这可能是一个非常糟糕的主意，你告诉我)当有人请求 .MP3 时，我可能能够设置 Apache 来提供 PHP 文件.

So I'm thinking (and this may be a really bad idea, you tell me) that I might be able to set up Apache to serve a PHP file when someone requests an .MP3.

所以我有三个问题

这行得通吗
好主意/坏主意?
我需要做什么?将AddType application/x-httpd-php .mp3"放入 httpd conf 中可以吗?

推荐答案

您的代码中存在一些错误:

There are some errors in your code:

一个资源只能有一个内容-输入值.因此，您必须决定要使用的媒体类型.我建议 audio/mpeg.
您忘记在内容中指定配置-处置.如果您只想提供文件名而不想更改配置，请使用默认值 inline.

其余看起来不错.但如果找不到文件，我也会发送 404 状态码.

The rest looks fine. But I would also send the 404 status code if the file cannot be found.

$track = "lilly.mp3";

if (file_exists($track)) {
    header("Content-Type: audio/mpeg");
    header('Content-Length: ' . filesize($track));
    header('Content-Disposition: inline; filename="lilly.mp3"');
    header('X-Pad: avoid browser bug');
    header('Cache-Control: no-cache');
    readfile($track);
    exit;
} else {
    header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found', true, 404);
    echo "no file";
}
