大家好!
我有一个小小的音乐应用,其中的文件是从“http://www.mymusicapp.com/get_song.php?name=SOME_MUSIC”这样的网址加载的。本地应用程序工作正常!但是,当我把它放在服务器上时,我的应用程序会在浏览器控制台中生成错误。
浏览器错误 Uncaught InvalidStateError:尝试使用不可用或不再可用的对象
我的PHP代码是......
$song_name = $_GET['name'];
$song_file = "{$_SERVER['DOCUMENT_ROOT']}/assets/musics/{$song_name}.mp3";
if( file_exists( $song_file ) )
{
header("Content-Type: audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3");
header('Content-Length: ' . filesize($song_file));
header('Content-Disposition: attachment; filename="'.$song_name.'.mp3"');
header("Content-Transfer-Encoding: binary");
header('X-Pad: avoid browser bug');
readfile( $song_file );
}
答案 0 :(得分:0)
也许可行:
$filename = $_GET['name'];
$real_path = "{$_SERVER['DOCUMENT_ROOT']}/assets/musics/{$filename}.mp3";
$mime_type = "audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3";
if(file_exists($real_path)) {
header('Content-type: {$mime_type}');
header('Content-length: ' . filesize($real_path));
header('Content-Disposition: filename="' . $filename . '.mp3"');
header('X-Pad: avoid browser bug');
header('Cache-Control: no-cache');
readfile($real_path);
} else {
header("HTTP/1.0 404 Not Found");
}
