Soundmanager2,Safari和PHP流错误

Question

我使用的是soundmanager2,我遇到了Safari问题.

我成功地将受保护的文件(在webroot之外)从PHP传输到Soundmanager2,使用类似这样的东西:

//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上工作正常,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)

我从PHP流式传输文件时只收到此错误,它正在使用webroot中的文件(由apache而不是PHP提供).

如果我直接访问www.myurl.com/privateaccess/index/1415,则会下载该文件,因此Safari,Soundmanager2和PHP文件流之间似乎存在问题.

任何人？一个想法来修复/解决这个问题？

您需要支持字节范围请求.请参阅SoundManager2关于此主题的技术说明.

示例请求:

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

预期回应:

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