How to implement Content-Disposition: attachment?
提问by Jean Hules
I am trying to make it so that mp3's on my site are downloaded by left clicking instead of having to right click and save as, So in order to do that, I have to set the Content-Disposition: attachment. This is my first website so I am new to how to actually do this, but do I do this in my html markup or do I set this somehow with my hosting site?
我正在尝试通过左键单击下载我网站上的 mp3，而不必右键单击并另存为，因此为了做到这一点，我必须设置 Content-Disposition: 附件。这是我的第一个网站，所以我不知道如何实际执行此操作，但是我是在我的 html 标记中执行此操作还是使用我的托管站点以某种方式设置它？
Here is an example of what my markup looks like.
这是我的标记外观的示例。
<div class="download">
<a href="MP3/Morgan Page, Sultan & Ned Shepard, and BT feat. Angela McCluskey.mp3"
<img src="img/dlicon.png"/></a>
</div>

As others have said, you don't do that in HTML, and a dynamic solution (e.g., using PHP) is overkill.
正如其他人所说，您不会在 HTML 中这样做，并且动态解决方案（例如，使用 PHP）是多余的。
In your case, I'd configure the Content-Disposition header in the web server config. For Apache, you could set the header based on location, or have a .htaccessfile that matches certain filenames.
在您的情况下，我会在 Web 服务器配置中配置 Content-Disposition 标头。对于 Apache，您可以根据 location设置标头，或者使用与某些文件名匹配的.htaccess文件。

There's a special function for that in PHP, too:
在 PHP 中也有一个特殊的函数：
bool http_send_content_disposition ( string $filename [, bool $inline = false ] )
bool http_send_content_disposition ( string $filename [, bool $inline = false ] )
See PHP Manualhere: http://de2.php.net/manual/en/function.http-send-content-disposition.php
请参阅此处的PHP 手册：http: //de2.php.net/manual/en/function.http-send-content-disposition.php
