如何使用和不使用斜杠来修复htaccess

Question

Hello I am facing a very little problem, when i browse site without trailing slash it works fine but when i add trailing slash in the end it redirect me to 404 page

eg

mysite.com/category/slug-name/page/3/

mysite.com/category/slug-name/page/5/

works fine but when i click page 1 it that has a trailing slash ie

mysite.com/category/slug-name/

it gives error but without trailing slash it works fine for me

Similarly on articles page when i access without trailing slash it works but when i add trailing slash in the end, It redirects me to 404 page eg when i access this URL it works fine

mysite.com/123-article-slug-here

but in this case I got 404 error

mysite.com/123-article-slug-here/

I am sure that there is a problem in my htaccess but know how to fix it

RewriteEngine On
RewriteRule ^category/([a-zA-Z0-9-/]+)/page/(.+)/?$ category.php?id=$1&page=$2 [NC,L]
RewriteRule ^category/([a-zA-Z0-9-/]+)/?$ category.php?id=$1 [L]
RewriteRule ^([a-zA-Z0-9-/]+)/?$ article.php?url=$1

Try either removing the / from the slug name regex grouping or make that match non-greedy:

Remove / from grouping:

RewriteEngine On
RewriteRule ^category/([a-zA-Z0-9-]+)/page/(.+)/?$ category.php?id=$1&page=$2 [NC,L]
RewriteRule ^category/([a-zA-Z0-9-]+)/?$ category.php?id=$1 [L]
RewriteRule ^([a-zA-Z0-9-]+)/?$ article.php?url=$1

Make non-greedy:

RewriteEngine On
RewriteRule ^category/([a-zA-Z0-9-/]+?)/page/(.+)/?$ category.php?id=$1&page=$2 [NC,L]
RewriteRule ^category/([a-zA-Z0-9-/]+?)/?$ category.php?id=$1 [L]
RewriteRule ^([a-zA-Z0-9-/]+?)/?$ article.php?url=$1

What's probably happening is that the / is getting matched inside the grouping (the parens) and that is getting passed to your category.php , and it doesn't like the / so returns a 404.
