# Add trailing slash to the end of the link
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteCond %{REQUEST_URI} !^/wp-json
RewriteCond %{REQUEST_FILENAME} !\\.(gif|jpg|png|jpeg|css|js|xml)$ [NC]

# End Adding trailing slash to the end of the link

RewriteCond %{REQUEST_URI} !^/wp-json 在
RewriteRule
