Question

我正在使用soundmanager2，我遇到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);
        }

这适用于Firefox和Chrome，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)

当我从PHP流式传输文件时，我只收到此错误，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？想要修复/解决这个问题吗？

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

预期回应：

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