How to configure redirects to url with trailing slash in nginx?

Question

I want to redirect URLs without slash to the path with trailing slash. So /some-url to /some-url/

And the rest of the URLs, like

• /some-url.xml
• /some-url?
• /some-url?q=v
• /some-url/

Should stay without redirection.

I found this article https://www.ateamsystems.com/tech-blog/nginx-add-trailing-slash-with-301-redirect-without-if-statements/ in which author suggests to use following rule:

location ~ ^([^.\?]*[^/])$ {
   try_files $uri @addslash;
}

location @addslash {
    return 301 $uri/;
}

Unfortunately this doesn't really work. Because url /some-url?q=v gets redirected to /some-url/

Could you suggest how to change regular expression to make it work?

Answer 1

This should solve the problem:

location / {
    if ($request_uri ~ ^([^.\?]*[^/])$) {
        return 301 $1/;
    }

    try_files $uri $uri/ /index.php$is_args$args;
}
