Question

我正在构建一个包含文件服务脚本的网站。此脚本允许网站提供 pdf，mp3和mp4文件。但只有PDF和MP3文件正常工作。通过点击播放视频，我希望视频文件可以播放，但事实并非如此。视频控件已被禁用且无法播放。

files.php

<?php
error_reporting(E_All);

$fid = $_GET['fid'];
$ftype = $_GET['ftype']; // e.g. audios, videos, ebooks
$fcat = isset($_GET['cat']) ? $_GET['cat'] . '/' : ''; // e.g. lessons, more
$fext = '';
$fmime = '';

switch ($ftype) {
    case 'ebooks':
        $fext = '.pdf';
        $fmime = 'application/pdf';
        break;
    case 'audios':
        $fext = '.mp3';
        $fmime = 'audio/mp3';
        break;
    default:
        $fext = '.mp4';
        $fmime = 'video/mp4';
        break;
}

// example: audios/lessons/audio1.mp3
$file = $ftype . '/' . $fcat . str_replace('s', '', $ftype) . $fid . $fext;

if (file_exists($file))
{   
    // open the file as binary mode
    $fp = fopen($file, 'rb');

    // send the right headers
    header('Cache-Control: no-store, no-cache, must-revalidate, max-age=0');
    header('Cache-Control: post-check=0, pre-check=0', false);
    header('Pragma: no-cache');
    header('Content-type: ' . $fmime);
    header('Content-Length: ' . filesize($file));

    // dump the file then stop the program
    fpassthru($fp);
    exit;
}
else
{
    die('File loading failed.');
}

video.php

<video src="/products/files.php?fid=1&ftype=videos&cat=lessons" autoplay controls></video>

或者，到地址栏

mydomain.com/products/files.php?fid=1&ftype=videos&cat=lessons

其他人可以找出我做错了什么吗？提前谢谢。

我终于使用X-Sendfile apache模块

解决了这个问题

<?php
if (file_exists($file))
{
    // send the right headers
    header('Cache-Control: no-store, no-cache, must-revalidate, max-age=0');
    header('Cache-Control: post-check=0, pre-check=0', false);
    header('Pragma: no-cache');
    header('Content-type: ' . $fmime);
    header('Content-Length: ' . filesize($file));

    // Make sure you have X-Sendfile module installed on your server
    // To download this module, go to https://www.apachelounge.com/download/
    header('X-Sendfile: ' . $file);

    // dump the file then stop the program
    fpassthru($fp);
    exit;
}
else
{
    die('File loading failed.');
}

PHP文件使用X-Sendfile服务
