cakephp下载png文件 [英] cakephp download png file

问题描述

我动态生成png文件，点击生成按钮后出现下链接。

I dynamically generate png files which after clicking "generate" button appears "under" link.

 "generate button : click" ---> <a href="new_generated.png">DOWNLOAD</a>

点击链接后下载我希望链接的内容（在我的情况下png）开始下载 - 另一个窗口，但下载！
我使用cakePHP。

After clicking link DOWNLOAD I wish content of link(in my case png) start download - no open in another window but download! I am using cakePHP. Can I please for help?

推荐答案

或者，如果您使用Apache Web服务器并启用了mod_headers，您可以使用.htaccess文件强制下载png文件。

Alternatively if you are using Apache web server and have mod_headers enabled you can use an .htaccess file to force download of the png files.

创建一个.htacess文件，并将其放在正在生成/下载png文件的目录中。在该文件中输入：

Create a .htacess file and place it in the directory where your png files are being generated/downloaded from. In that file put this:

<FilesMatch "\.(?i:png)$">
  ForceType application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>
