我有一个在 webroot 之外上传的脚本。然后，我通过该网站将用户链接到图像文档等。

因此对于图像，链接将是:

media.php?file=nameoffile.jpg&user=userid&folder=images

然后用于显示图像:

<img src="media.php?file=nameoffile.jpg&user=userid&folder=images" width="100" border="0">

这适用于图像并提供下载文档的链接。

我面临的问题是嵌入，我使用 ffmpeg 将所有允许的视频类型转换为 flv(这些视频已经过测试并且效果很好)，但是当我尝试嵌入 flv 视频时它永远不起作用(它适用于直接链接文件只是不通过 media.php)。如果可能，我还想嵌入 .swf。

我正在使用 jwplayer 嵌入(使用文件的直接链接而不是通过 media.php)

        <!-- START OF THE PLAYER EMBEDDING TO COPY-PASTE --> 
            <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="328" height="200">

            <embed 
                type="application/x-shockwave-flash"
                id="player2"
                name="player2"
                src="player.swf"
                width="328" 
                height="200"
                allowscriptaccess="always" 
                allowfullscreen="true"
                flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos"
            /> 
            </object> 
            <script type="text/javascript" src="jwplayer.js"></script>
            <!-- END OF THE PLAYER EMBEDDING --> 

这是 media.php:

        $path_parts = pathinfo($_SERVER['REQUEST_URI']);
        $file = basename(urldecode($_GET['file']));
        $user = basename(urldecode($_GET['user']));
        $folder = basename(urldecode($_GET['folder']));
        $ext = pathinfo($file, PATHINFO_EXTENSION);

        $fileDir = 'pathoutsidewebroot';
        $filePath = $fileDir . $file;

        switch(
        $ext) {
            case "flv": $ctype="video/x-flv"; break;
            // adobe
            case "pdf": $ctype="application/pdf"; break;
            // ms office
            case "doc": $ctype="application/msword"; break;
            case "rtf": $ctype="application/rtf"; break;
            case "xls": $ctype="application/vnd.ms-excel"; break;
            case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
            // open office
            case "odt": $ctype="application/vnd.oasis.opendocument.text"; break;
            case "ods": $ctype="application/vnd.oasis.opendocument.spreadsheet"; break;
            default: $ctype = "application/force-download"; break; 
}

        if(in_array($ext, $valid_formats_vid)){
            if (file_exists($filePath)) {
                header('Content-Type: ' . mime_content_type($filePath));
                header('Content-Length: ' . filesize($filePath));
                readfile($filePath);
        }
        }

        else if(in_array($ext, $valid_formats_img)) {
            if (file_exists($filePath)) {
                header('Content-Type: ' . mime_content_type($filePath));
                header('Content-Length: ' . filesize($filePath));
                readfile($filePath);
            }
        }
        else if(in_array($ext, $valid_formats_docs)) {
                    if (file_exists($filePath))
                    {
            header("Pragma: public");
            header("Expires: 0");
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
            header("Cache-Control: private",false);
            header("Content-Type: $ctype");
            header("Content-Disposition: attachment; filename=\"".basename($filePath)."\";");
            header("Content-Transfer-Encoding: binary");
            header("Content-Length: ".@filesize($filePath));
            set_time_limit(0);
            @readfile($filePath) or die("File not found.");                 }
        }

通过 media.php 嵌入的 header

Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Connection:Keep-Alive
Content-Disposition:filename=encoded_2012-10-19_22.37.09_1359032866.flv

Pragma:no-cache

从直接链接到文件的 header (有效的那个)

Accept-Ranges:bytes
Connection:Keep-Alive
Content-Length:2428614
Content-Type:video/x-flv
Date:Thu, 24 Jan 2013 16:23:54 GMT

设法通过 media.php 将其更改为此(但仍然无法正常工作)

            header("Content-Type: $ctype");
            header('Content-Length: ' . filesize($filePath));
            header('Accept-Ranges: bytes');
            $now = time( );
            $then = gmstrftime("%a, %d %b %Y %H:%M:%S GMT", $now + 365*86440);
            header("Expires: $then");
            ob_clean();
            flush();
            readfile($filePath);



Accept-Ranges:bytes

最佳答案

问题出在这里:

flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos"

flashvars 收到一个查询字符串，所以这被解释为

file   : media.php?file=nameoffile.flv
user   : userid
folder : videos

您需要对文件参数进行urlencode:

flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos"

关于php - 嵌入位于 webroot 之外的 flv 和 swf，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14435451/
