我正在使用smartReadFile
我在网上找到的这种 PHP 方法将音频流式传输到 jQuery jPlayer
。虽然这在从浏览器播放时效果很好,但我可以搜索曲目并显示持续时间,但是当我在 iOS Safari 上尝试时,持续时间是未知的,我无法搜索,但它确实可以播放。有什么想法吗?非常感激。
function _smartReadFile($location, $filename, $mimeType = 'application/octet-stream')
{
if (!file_exists($location))
{
header ("HTTP/1.1 404 Not Found");
return;
}
$size = filesize($location);
$time = date('r', filemtime($location));
$fm = @fopen($location, 'rb');
if (!$fm)
{
header ("HTTP/1.1 505 Internal server error");
return;
}
$begin = 0;
$end = $size - 1;
if (isset($_SERVER['HTTP_RANGE']))
{
if (preg_match('/bytes=\h*(\d+)-(\d*)[\D.*]?/i', $_SERVER['HTTP_RANGE'], $matches))
{
$begin = intval($matches[1]);
if (!empty($matches[2]))
{
$end = intval($matches[2]);
}
}
}
if (isset($_SERVER['HTTP_RANGE']))
{
header('HTTP/1.1 206 Partial Content');
}
else
