htaccess重定向规则信息重定向重写

Question

I have to set a rule on my htaccess file that redirects me all the images ex: img_4324_r.jpg to img_4324_s.jpg

all images

Answer 1

For your exact example:

RewriteRule ^img_([0-9]+)_r\.jpg$ img_$1_s.jpg [R=301,L,NC]

if you have several extension with the same pattern:

RewriteRule ^img_([0-9]+)_r\.(jpe?g|png|gif)$ img_$1_s.$2 [R=301,L,NC]

Only to jpg:

RewriteRule ^img_([0-9]+)_r\.(jpe?g|png|gif)$ img_$1_s.jpg [R=301,L,NC]

You can repeat for each patterns if you have others, just capture what you need and use it

You also may need to add this at the top of you .htaccess:

RewriteEngine On
RewriteBase /

Answer 2

RewriteRule ([^.]+\.(jpe?g|gif|bmp|png)) /img_4324_s.jpg [R=301,L,NC]

应该可以，但是不能100％确定您的要求。
