blocks|key|1232302|text|本页上一个答案描述了如何使用.htaccess强制下载特定类型的所有文件。但是，该解决方案并不适用于所有浏览器上的所有文件类型。这是一种更可靠的方式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1232303|<FilesMatch+"\.(?i:csv)$">
++ForceType+application/octet-stream
++Header+set+Content-Disposition+attachment
</FilesMatch>|code-block|syntax|javascript|1232304|您可能需要刷新浏览器缓存才能正常工作。|1232305|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>A previous answer on this page describes how to use .htaccess to force all files of a certain type to download. However, the solution does not work with all file types across all browsers. This is a more reliable way:</p>

<pre><code>&lt;FilesMatch "\.(?i:csv)$"&gt;
  ForceType application/octet-stream
  Header set Content-Disposition attachment
&lt;/FilesMatch&gt;
</code></pre>

<p>You might need to flush your browser cache to see this working correctly.</p>


blocks|key|1447205|text|或者，您可以使用HTML5来完成此操作。简单地使用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1447206|<a+href="example.csv"+download>download+not+open+it</a>|code-block|syntax|javascript|1447207|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>Or you can do this using HTML5. Simply with </p>

<p>I have a CSV file on my server. If a user clicks on a link it should download, but instead it opens up in my browser window.</p>

<p>My code looks as follows</p>

<pre><code>&lt;a href="files/csv/example/example.csv"&gt;
    Click here to download an example of the "CSV" file
&lt;/a&gt;
</code></pre>

<p>It's a normal webserver where I have all of my development work on.</p>

<p>I tried something like:</p>

<pre><code>&lt;a href="files/csv/example/csv.php"&gt;
    Click here to download an example of the "CSV" file
&lt;/a&gt;
</code></pre>

<p>Now the contents of my <code>csv.php</code> file:</p>

<pre><code>header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=example.csv');
header('Pragma: no-cache');
</code></pre>

<p>Now my issue is it's downloading, but not my CSV file. It creates a new file.</p>
