apache - Trailing Slash 301 Redirect Issue When ? Is In URL -

htaccess | 301 redirect | uri issue

i applied code htaccess enforce trailing slash on url:

#trailing backslash rewritebase / rewritecond %{http_host} !^www\. [nc] rewriterule ^(.*)$ https://www.example.com/$1 [r=301,l] rewritecond %{request_filename} !-f rewritecond %{request_uri} !(.*)/$ rewriterule ^(.*)$ $1/ [l,r=301]

the code works great @ adding / @ end of urls except ? in middle of url. below:

https://www.example.com/list-of-all-objects/search?keywords=test

this url code stated above change on load this: https://www.example.com/list-of-all-objects/search/?keywords=test

when should this: https://www.example.com/list-of-all-objects/search?keywords=test/

i have learnt of code have applied not work 2 reasons.

they don't enforce / - make possible if blocked
the term request_uri or $1 or $2 don't include ?keyword= (in fact there nothing can find refers part of url can't include correctly)

no matter - can't ? or after placed before /. how trailing slash not applied before ? on keyword search @ end of url , continue applied @ end of other url's?

other tried methods:

 # force trailing slash enter code hererewritecond %{request_filename} !-f rewriterule ^(.*)([^/])$ http://%{http_host}/$1$2/ [l,r=301]

found here: .htaccess rewrite force trailing slash @ end

rewriteengine on rewritecond %{request_filename} !-f rewriterule ^(.*[^/])$ /$1/ [l,r=301]

query_string not part of match in rewriterule.

to add trailing slash query strings, can use :

rewritecond %{query_string} ([^/]+)$ [nc] rewriterule ^ %{request_uri}?%1/ [r,l]

edit :

as said, query strings can not handled directly rewriterule directive, need separate rule add trailing slash query strings.

the example bellow adds trailing slash both parts of url.

  rewriteengine on    #add trailing slash uri   rewritecond %{request_uri} !/$   rewriterule ^ %{request_uri}/ [nc,l,r]   #add trailing slash query strings   rewritecond %{query_string} ([^/]+)$ [nc]  rewriterule ^ %{request_uri}?%1/ [r,l]

this change following urls :
