通过PHP发送要与HTML5的音频标签一起使用的mp3文件在mp3中间失败 [英] Sending mp3 file through PHP to be used with the audio tag of HTML5 fails in the middle of the mp3
问题描述
我正在尝试通过PHP脚本发送mp3文件，以便在HTML中隐藏文件的路径.一切工作都很好，除了进入mp3 chrome的一半，这给了我GET [URL]错误.而mp3的其余部分仅为空白.音频标签认为它仍在读取文件，但没有声音.
I'm trying to send my mp3 files through a PHP script in order to hide the path to the file in the HTML. Everything works perfectly fine except half way into the mp3 chrome gives me a GET [URL] error. And the rest of the mp3 is just blank. The audio tag thinks it's still reading the file, but there is no sound.
这就是我从php发送mp3文件的方式:
This is how I'm sending the mp3 file from php:
if (file_exists($filename)) {
header("Content-Transfer-Encoding: binary");
header("Content-Type: audio/mpeg");
header('Content-length: ' . filesize($filename));
header('Content-Disposition: inline; filename="' . $filename . '"');
header('X-Pad: avoid browser bug');
header('Cache-Control: no-cache');
readfile($filename);
exit;
}
else {
header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found', true, 404);
echo "no file";
}
我添加了Etag标头.这似乎使事情变得更好.该问题仍然存在，但没有那么频繁. :-/
I added the Etag header. It seems to make things better. The problem still occurs but not as often. :-/
Edit2:我注意到发送到我的PHP文件的请求标头与直接发送到mp3文件的标头不同.实际上，有一个HTTP_RANGE请求发送到mp3文件，但是当我尝试从PHP中获取内容时，此范围请求丢失了. (这是在Chrome中).知道为什么会这样吗?
I have noticed that the request headers sent to my PHP file is different from the headers sent directly to the mp3 file. Actually there's a HTTP_RANGE request sent to the mp3 file, but this range request is missing when I try to fetch things from PHP. (This is in Chrome). Any idea why this might be ?
推荐答案
我知道这是一篇旧文章，但是我能够使用两个文件以及index.php和example.php来使它工作.
I know this is an old post but I was able to get this working with two files and index.php and example.php.
这是example.php，它正在检查数据库中的哈希值和使用过的字段，以了解该文件之前是否已使用过
this is example.php that's checking a databse for a hash and a used field to know if the file has been used before
<?php
if(isset($_GET['hash'])){
$mysqli = new mysqli('host_here','user_here','password_here','database_here');
$result = $mysqli->query("select * from hashes where hash = '{$_GET['hash']}' limit 1");
$row = $result->fetch_array();
}
if(isset($row['used']) && $row['used'] == 0){
$mysqli->query("update hashes set used=1 where hash = '{$_GET['hash']}'");
$filename = "example.mp3";
header("Content-Transfer-Encoding: binary");
header("Content-Type: audio/mpeg");
header('Content-length: ' . filesize($filename));
//If this is a secret filename then don't include it.
header('Content-Disposition: inline');
//Otherwise you can add it like so, in order to give the download a filename
//header('Content-Disposition: inline;filename='.$filename);
header('Cache-Control: no-cache');
readfile($filename);
exit;
}
elseif(isset($row['used']) && $row['used'] == 1){
die("you can't just download this dude");
}
，这里是带有音频标签的index.php，它将允许播放但不能下载mp3.
and here is index.php with the audio tag that will allow playing but not downloading of the mp3.
<html>
<body>
<?php
$mysqli = new mysqli('localhost','root','','test_mp3');
$rand = mt_rand();
$hash = md5($rand);
$result = $mysqli->query("insert into hashes (hash,used) values('$hash',0)");
?>
<audio controls>
<source src="example.php?hash=<?=$hash?>" type="audio/mpeg">
</audio>
</body>
</html>
有一个数据库表，其中仅包含一个哈希表和一个用于此示例的used字段
there is a database table with just a hash and a used field for this example to work
