Soundmanager2、Safari和PHP流错误

Question

我正在使用soundmanager2，我在使用Safari时遇到了问题。

我成功地将受保护的文件(在webroot之外)从PHP传输到Soundmanager2，使用如下代码：

//check if user is logged in and has rights on $file
//if yes stream file

        if (file_exists($file)) { 
            $filepath = $file;
            $filesize = filesize($filepath);

            header("Pragma: no-cache");
            header("Expires: 0");
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
            header('Content-Disposition: attachment;filename="'.$filename.'"');
            header("Content-Transfer-Encoding: binary");
            header('Content-Type: audio/mpeg');
            header('Content-Length: '.$filesize);
            @readfile($filepath);
            exit(0);
        } 

这在火狐和Chrome上运行得很好，mp3文件正在播放，但在Safari中我得到：

soundmanager2.js:1190basicMP3Sound0: Using HTML5
soundmanager2.js:1190basicMP3Sound0: play(): Attempting to load
soundmanager2.js:1190basicMP3Sound0: load (/privateaccess/index/1415)
soundmanager2.js:1190basicMP3Sound0: waiting
soundmanager2.js:1190basicMP3Sound0: loadstart
soundmanager2.js:1190basicMP3Sound0: loadedmetadata
soundmanager2.js:1190basicMP3Sound0: HTML5 error, code 3
soundmanager2.js:1188basicMP3Sound0: Failed to load / invalid sound? Zero-length duration reported. (/privateaccess/index/1415)

只有当我从PHP流式传输一个文件时，我才会得到这个错误，它正在处理webroot中的文件(由apache而不是PHP提供)。

如果我直接点击www.myurl.com/privateaccess/index/1415，文件就会被下载，所以这看起来像是Safari，Soundmanager2和PHP文件流之间的问题。

有没有人？一个解决/解决这个问题的想法？

您需要支持字节范围请求。See SoundManager2's Technical Notes on the subject.

请求示例：

GET some.ogg HTTP/1.1
Range: bytes=5210604-5275910

预期响应：

HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-length: 65307
Content-Range: bytes 5210604-5275910/5275911
Content-Type: audio/ogg
