保护视频不被浏览器窃取 [英] protecting videos from being stolen in browser

问题描述

在我的逻辑下面，我试图阻止视频被盗，但我被困在某个地方。



i创建了一个页面index.php

Below i logic i am trying to prevent video from being stole but i got stuck some where.

i created a page index.php

<?php

    session_start();

    $_SESSION["check"]="aaa";

?>
<video width="320" height="240" controls>
    <source src="video.php" type="video/mp4">
</video>

和video.php

and video.php

$file = "a.mp4";
    $file_size = filesize($file);
    $fp = fopen($file, "rb");
    $data = fread ($fp, $file_size);
    fclose($fp);
    header ("Content-type: video/mp4");

    if(md5($_SESSION["check"])=="aaa"){
       echo $data;
    }else{

    }

但是我希望当用户打开video.php他应该只是得到一些消息或错误而不是视频

因为用户可以获得关于video.php的会话价值

他仍然能够以任何方式查看和保存视频来实现此目的

but i want when user open video.php he should simply get some message or error but not videos
as user can get value of session on video.php
he still is able to see and save video any way to pervent this

推荐答案

_SESSION [check] = aaa ;

< video 宽度 = 320 height = 240 控件 >
< 来源 src = video.php type = video / mp4 >
< / video >

_SESSION["check"]="aaa"; ?> <video width="320" height="240" controls> <source src="video.php" type="video/mp4"> </video>

和video.php

and video.php

file = a.mp4;

file = "a.mp4";

file_size = filesize（

file_size = filesize(
