隐藏MP3完整网址 [英] Hide MP3 full url
问题描述
我有一个音乐播放器，它使用以下语法链接到歌曲:
<li><a href="" data-src="http://s3.amazonaws.com/audiojs/02-juicy-r.mp3">title</a></li>
有什么办法可以让我在服务器端执行该程序，然后为用户显示(如下所示)?
在搜索时，我遇到了这个问题...我喜欢拥有一个包含数据的外部文件背后的想法...
<?php
// get-file.php
// call with: http://yoururl.com/path/get-file.php?id=1
$id = (isset($_GET["id"])) ? strval($_GET["id"]) : "1";
// lookup
$url[1] = 'link.mp3';
$url[2] = 'link2.mp3';
header("Location: $url[$id]");
exit;
?>
然后使用: http://yoururl.com/path/get-file .php?id = 1 作为链接...唯一的问题是，当您键入 http://yoururl.com/path/get-file.php?id=1 用户直接进入文件...有什么方法可以禁用该功能...也许get-file.php本身有一些代码?
好吧，所以我做了一些令我满意的事情……虽然并不完全安全，但是它确实使我相当困惑. /p>
首先，我正在使用AudioJS播放器播放音乐-可以找到: http://kolber.github.com/audiojs/
基本上我所做的是:
- 我没有将"data-src"用作我的歌曲的路径，而是将其称为键"，因此人们不一定会认为它是路径.
- 我没有使用"my-song-title"作为歌曲的名称，而是将其更改为7364920之类的数字，这样人们就无法在源中查找并以这种方式找到URL. li>
- 我在所有关键"变量之后都在JavaScript代码中添加了"mp3"，这样就不必在混淆链接中声明它.
- 我使用的是相对路径，例如"./8273019283/"，而不是"your-domain.com/8273019283/"，这样一来，很难说出我正在显示网址.
- 在href上添加了iTunes链接，这样人们可能会对我如何提取文件感到困惑.
所以，现在我的内联javascript看起来像:
<script type="text/javascript">
$(function() {
// Play entire album
var a = audiojs.createAll({
trackEnded: function() {
var next = $("ul li.playing").next();
if (!next.length) next = $("ul li").first();
next.addClass("playing").siblings().removeClass("playing");
audio.load($("a", next).attr("key") + "mp3");
audio.play();
}
});
// Load the first song
var audio = a[0];
first = $("ul a").attr("key") + "mp3";
$("ul li").first().addClass("playing");
audio.load(first);
// Load when clicked
$("ul li").click(function(e) {
e.preventDefault();
$(this).addClass("playing").siblings().removeClass("playing");
audio.load($('a', this).attr('key') + "mp3");
audio.play();
});
});
</script>
我的链接如下:
<a href="<?php $link = 'http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4'; $obfuscatedLink = ""; for ($i=0; $i<strlen($link); $i++){ $obfuscatedLink .= "&#" . ord($link[$i]) . ";"; } echo $obfuscatedLink; ?>" target="itunes_store" key="<?php $link = './8249795872/9273847591.'; $obfuscatedLink = ""; for ($i=0; $i<strlen($link); $i++){ $obfuscatedLink .= "&#" . ord($link[$i]) . ";"; } echo $obfuscatedLink; ?>">Falling</a>
在浏览器中加载它并查看源时，您将看到:
<a href="http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4" target="itunes_store" key="./8249795872/9273847591.">Falling</a>
然后，当您使用Web Inspector或Firebug时，您将看到:
<a href="http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4" target="itunes_store" key="./8249795872/9273847591.">Falling</a> - *which doesn't completely give the url away
基本上，我所做的是使链接看起来像是某种api键.很棒的事情是，您不能直接从视图源直接复制链接，也不能直接从Web Inspector/Firebug复制链接.它不是万无一失的，并且肯定会被破坏，但是用户必须知道他们在做什么.它使大多数人望而却步，但仍然允许播放器获取播放歌曲所需的网址:)
*而且，我从Stack Exchange上的某个地方获得了php模糊脚本，只是不确定在哪里.
I have a music player that links to a song using the following syntax:
<li><a href="" data-src="http://s3.amazonaws.com/audiojs/02-juicy-r.mp3">title</a></li>
Is there any way that I could have that executed server side and then be displayed like (see below) for the user?
While searching, I ran across this...I like the idea behind having an external file that has the data...like:
<?php
// get-file.php
// call with: http://yoururl.com/path/get-file.php?id=1
$id = (isset($_GET["id"])) ? strval($_GET["id"]) : "1";
// lookup
$url[1] = 'link.mp3';
$url[2] = 'link2.mp3';
header("Location: $url[$id]");
exit;
?>
then using: http://yoururl.com/path/get-file.php?id=1 as the link...the only problem is that when you type http://yoururl.com/path/get-file.php?id=1 the user goes straight to the file...is there any way to disable that ability...maybe some code on get-file.php itself?
Ok, so I did a combination of things that I am satisfied with...although not completely secure, it definitely helped me obscure it quite a bit.
First of all, I am using the AudioJS player to play music - which can be found: http://kolber.github.com/audiojs/
Basically what I did was:
- Instead of using "data-src" as the path to my songs I called it "key", that way people wouldn't necessarily think it was a path.
- Instead of using "my-song-title" as the name of the songs, I changed it to a number like 7364920, that way people couldn't look for that in the source and find the url that way.
- I added + "mp3" to the javascript code after all of the "key" variables, that way I would not have to declare it in obfusticated link.
- I used a relative path like "./8273019283/" instead of "your-domain.com/8273019283/", that way it would be harder to tell that I was displaying a url.
- Added an iTunes link to the href, that way people might get confused as to how I was pulling the file.
So, now my inline javascript looks like:
<script type="text/javascript">
$(function() {
// Play entire album
var a = audiojs.createAll({
trackEnded: function() {
var next = $("ul li.playing").next();
if (!next.length) next = $("ul li").first();
next.addClass("playing").siblings().removeClass("playing");
audio.load($("a", next).attr("key") + "mp3");
audio.play();
}
});
// Load the first song
var audio = a[0];
first = $("ul a").attr("key") + "mp3";
$("ul li").first().addClass("playing");
audio.load(first);
// Load when clicked
$("ul li").click(function(e) {
e.preventDefault();
$(this).addClass("playing").siblings().removeClass("playing");
audio.load($('a', this).attr('key') + "mp3");
audio.play();
});
});
</script>
My link looks like:
<a href="<?php $link = 'http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4'; $obfuscatedLink = ""; for ($i=0; $i<strlen($link); $i++){ $obfuscatedLink .= "&#" . ord($link[$i]) . ";"; } echo $obfuscatedLink; ?>" target="itunes_store" key="<?php $link = './8249795872/9273847591.'; $obfuscatedLink = ""; for ($i=0; $i<strlen($link); $i++){ $obfuscatedLink .= "&#" . ord($link[$i]) . ";"; } echo $obfuscatedLink; ?>">Falling</a>
When you load it up in the browser and you view the source you'll see:
<a href="http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4" target="itunes_store" key="./8249795872/9273847591.">Falling</a>
Then when you use Web Inspector or Firebug you'll see:
<a href="http://itunes.apple.com/us/album/falling/id504779876?i=504779883&uo=4" target="itunes_store" key="./8249795872/9273847591.">Falling</a> - *which doesn't completely give the url away
Basically what I did was make the link look like it's an api-key of some-kind. The cool thing is that you can't just copy the link straight from view source or straight from Web Inspector/Firebug. It's not fool-proof, and can definitely be broken, but the user would have to know what they're doing. It keeps most people away, yet still allows the player to get the url it needs to play the song :)
*also, I got the php obfusticate script from somewhere on Stack Exchange, just not sure where.
