如何使用htaccess提供webp图像? [英] How to serve webp images using htaccess?

问题描述

如果图像(jpg或png)可用作webp，我想提供.webp图像.如果没有，我想显示jpg或png.

I would like to serve .webp images if the image (jpg or png) is available as webp. If not I want to show the jpg or png.

RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)\.(jpe?g|png)(.*)$ $1.$2.webp [NC,L]

AddType image/webp .webp

这个问题，我需要最终的网址是这样的:

The problem I need the final URL to be like:

"myurl.com/foo.jpg.webp" 

如果webp文件存在，并且我不需要:

If the webp file exists and if not I need:

"myurl.com/foo.jpg"

作为后备解决方案.

推荐答案

如果请求的URL以jpeg或png结尾，则可以使用

If the requested URL ends in jpeg or png, you might test for the corresponding webp with

RewriteCond %{REQUEST_FILENAME}.webp -f
RewriteRule ^ %{REQUEST_FILENAME}.webp [L]

如果愿意的话，您可能会有更多的限制

You may be more restrictive, if you like

RewriteCond %{REQUEST_FILENAME}.webp -f
RewriteRule \.(jpe?g|png)$ %{REQUEST_FILENAME}.webp [L]

如果条件和规则不匹配，请求将失败并按原样提供文件(.jpg/.png).

If the condition and rule don't match, the request will fall through and serve the file (.jpg/.png) as is.
