Removing the trailing slash from a URL with nginx

Solution 1:

Having this regex on your server block:

rewrite ^/(.*)/$ /$1 permanent;

would redirect all trailing slash URL's to the respective non trailing slash.

Solution 2:

Never use rewrite:

  location ~ (?<no_slash>.*)/$ {
       return 301 $scheme://$host$no_slash;
  }

---

Solution 3:

I was able to get my desired behavior by using this as the final server block in my configuration:

server {
  server_name example.com 123.45.67.89 localhost;
  listen 80 default_server;

  # Redirect /foobar/ and /foobar/index.html to /foobar
  rewrite ^(.+)/+$ $1 permanent;
  rewrite ^(.+)/index.html$ $1 permanent;

  root /usr/share/nginx/www/example.com;
  index index.html;
  try_files $uri $uri/index.html =404;

  error_page 404 /404.html;
  error_page 500 502 503 504 /50x.html;

  location = /50x.html {
    root /usr/share/nginx/html;
  }
}
