php - Soundmanager2、Safari 和 PHP 流式传输错误

Question

我正在使用 soundmanager2，但我在使用 Safari 时遇到了问题。

我成功地将 protected 文件(在 webroot 之外)从 PHP 流式传输到 Soundmanager2，使用如下内容:

//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 Firefox 和 Chrome 上运行良好，正在播放 mp3 文件，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)

我只在从 PHP 流式传输文件时遇到此错误，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，所以这看起来确实像是 Safari、Soundmanager2 和 PHP 文件流之间的问题。

有人吗？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.

示例请求:

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
