设置Apache以在需要MP3文件时提供PHP服务 [英] Setting up apache to serve PHP when an MP3 file is requested
问题描述
我正在研究通过PHP提供MP3文件的方法，并且在形成了大量的帮助后，我得到了它的工作这里
然而，当我使用它时，该示例似乎不起作用作为像这样的音频标签中的来源
< html>
< head>
< title>音频标签实验< / title>
< / head>
< body>
您的浏览器不支持音频元素。
< / audio>
< / body>
< / html>
这里是PHP
<？php
$ track =lilly.mp3;
$ b $ 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'）;
标题（'X-Pad：避免浏览器错误'）;
Header（'Cache-Control：no-cache'）;
readfile（$ track）;
} else {
echono file;
$ b $ p
$ b所以我在想（这可能是一个非常糟糕的主意，你告诉我）我可能能够设置Apache来在有人请求.MP3时提供PHP文件。 b
$ b
- 这项工作是否可行
- 好主意/坏主意？
- 我需要去做？将AddType application / x-httpd-php .mp3放入httpd conf中吗？
解决方案您的代码中存在一些错误：
- 资源只能有一个 Content-Type 值。所以你必须决定你想使用的媒体类型。我建议
audio / mpeg 。
- 你忘了在 Content-Disposition 。如果您只想提供文件名并且不想更改处置，请使用默认值
内联。
剩下的看起来很好。但如果找不到文件，我还会发送404状态码。
$ track =lilly.mp3;
if（file_exists（$ track））{
header（Content-Type：audio / mpeg）;
header（'Content-Length：'。filesize（$ track））;
header（'Content-Disposition：inline; filename =lilly.mp3'）;
标题（'X-Pad：避免浏览器错误'）;
头（'Cache-Control：no-cache'）;
readfile（$ track）;
退出;
} else {
header（$ _ SERVER ['SERVER_PROTOCOL']。'404 Not Found'，true，404）;
回显无文件;
}
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
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>
and here's the 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";
}
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.
So I've three questions
- Will this work
- Good Idea / Bad Idea?
- What would I need to do? Would putting "AddType application/x-httpd-php .mp3" int he httpd conf do it?
解决方案 There are some errors in your code:
- A resource can only have one single Content-Type value. So you have to decide what media type you want to use. I suggest
audio/mpeg.
- You forgot to specify the disposition in Content-Disposition. If you just want give a filename and don’t want to change the disposition, use the default value
inline.
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";
}
