Add Trailing Slash to Posts - regex

Question

I'm using following .htaccess code to add trailing slash all urls but homepage.
## Base Redirects ##
# Turn on Rewrite Engine
RewriteEngine On
# Include trailing slash on non-filepath urls
RewriteCond %{REQUEST_URI} !(.+)/$
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*)$ https://hamilekadin.net/$1/ [R=301,L]
# Remove trailing slash from directory
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+)/$ https://hamilekadin.net/$1 [R=301,L]
# Force HTTPS and remove WWW
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [OR,NC]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://hamilekadin.net/$1 [R=301,L]
I want non-www url's, https protocol and trailing slash after post and page url's.
With this .htaccess I'm getting 404 error on categories, pages, posts.
Also my permalink type is: /%postname%/

Answer 1

Here is the code for trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ http://yourdomainname.com/$1 [L,R=301]
For non-www url,there are two option
Option 1 :
You need to run SQL query to remove www from url
Option 2
Add following code in .htacess
RewriteCond %{HTTP_HOST} ^www. yourdomain\.com [NC]
RewriteRule ^(.*)$ https://yourdomain.com $1 [L,R=301,NC]
According to me to remove www most preferable way is option 1 where you just need to run the query.
