Add slash to the end of every url (need rewrite rule for nginx)

Question

I try to get an / to every urls end:

example.com/art

should

example.com/art/

I use nginx as webserver.

I need the rewrite rule for this..

For better understanding check this:

http://3much.schnickschnack.info/art/projekte

If u press on a small thumbnail under the big picture it reloads and shows this url:

http://3much.schnickschnack.info/art/projekte/#0

If i now have a slash on all urls (on the end) it would work without a reload of the site.

Right now i have this settings in nginx-http.conf:

server {
  listen *:80;
  server_name 3much.schnickschnack.info;
  access_log /data/plone/deamon/var/log/main-plone-access.log;
  rewrite ^/(.*)$ /VirtualHostBase/http/3much.schnickschnack.info:80/2much/VirtualHostRoot/$1 last;
  location / {
    proxy_pass http://cache;
  }
}

How do I configure nginx to add a slash? (I think i should a rewrite rule?)

I need it for a js gallery. If there is no "/" it reloads the site... — Gomez

So the question is "How do I configure nginx to add a slash?" Or is it "How do I configure nginx to work without a slash?" — S.Lott

More likely I think you would want something like this:

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

The Regular Expression translates to: "rewrite all URIs without any '.' in them that don't end with a '/' to the URI + '/'" Or simply: "If the URI doesn't have a period and does not end with a slash, add a slash to the end"

The reason for only rewriting URI's without dots in them makes it so any file with a file extension doesn't get rewritten. For example your images, css, javascript, etc and prevent possible redirect loops if using some php framework that does its own rewrites also

Another common rewrite to accompany this would be:

rewrite ^([^.]*)$ /index.php;

This very simply rewrites all URI's that don't have periods in them to your index.php (or whatever file you would execute your controller from).

This is the only post on the interwebs that doesn't add a trailing slash to EVERYTHING. thanks for posting.

anthonysomerset Over a year ago

this one works much more reliably particularly with php frameworks that do there own pretty link rewriting

Asle Over a year ago

I have static html files so this: domain.com/about gets the file domain.com/about.html but still shows the URL without ".html". I am looking to add a slash after I hit the file but get a 404 now if I add a slash. So I want to remove the trailing slash (if exists) and with or without trailing slash gets "-html" file but shows "/" after. This does not work: rewrite ^/([a-zA-Z0-9]+)$ /$1.html; rewrite ^([^.]*[^/])$ $1/ permanent; Also for click on "about" in a menu severa times I get this domain.com/about/about/about etc..

Efrain Over a year ago

Unfortunately, this doesn't seem to work if the URL contains a port: localhost:8080/something turns into localhost/something :T

Periplo Over a year ago

For those getting the port added to the URL, try with port_in_redirect off; in your config file, it worked for me.

rewrite ^([^.\?]*[^/])$ $1/ permanent;

to avoid querystrings of a rest url getting a / tagged on.

e.g.

/myrest/do?d=12345

how could you make the result ``` /myrest/do/?d=12345 ```

Satish Patro Over a year ago

@PatrickLeeScott Adding '?' to regex to exclude would be sufficient I think

Mechanic Over a year ago

@PatrickLeeScott I'd added an answer that case

Odd that this is the first result in Google, but doesn't have a satisfactory answer. There are two good ways to do this I know of. The first is to straight-up check if the request will hit a file and only apply a rewrite condition if not. E.g.

server {
   # ...
   if (!-f $request_filename) {
     rewrite [^/]$ $uri/ permanent;
   }
   location / {
      # CMS logic, e.g. try_files $uri $uri /index.php$request_uri;
   }
   # ...
}

The second, which many prefer as they'd rather avoid any use of if that isn't 100% necessary, is to use try_files to send the request to a named location block when it won't hit a file. E.g.

server {
   # ...
   location / {
      try_files $uri $uri/ @cms;
   }
   location @cms {
      rewrite [^/]$ $uri/ permanent;
      # CMS logic, e.g. rewrite ^ /index.php$request_uri;
   }
   # ...
}

For nginx:

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

This will add a slash to EVERYTHING - so you'll end up with index.php -> index.php/, and page?a=b -> page?a=b/ where what the OP surely wants is page?a=b -> page/?a=b

it's too late but I want to share my solution, I've met issue with trailing slash and nginx.

#case : 
# 1. abc.com/xyz  => abc.com/xyz/
# 2. abc.com/xyz/ => abc.com/xyz/
# 3. abc.com/xyz?123&how=towork => abc.com/xyz/?123&how=towork
# 4. abc.com/xyz/?123&ho=towork => abc.com/xyz/?123&how=towork

and this is my solution

server { 
    ....
    # check if request isn't static file
    if ($request_filename !~* .(gif|html|jpe?g|png|json|ico|js|css|flv|swf|pdf|xml)$ ) {
       rewrite (^[^?]+[^/?])([^/]*)$ $1/$2 permanent;
    }
    ....
    location / {
    ....
    }
}

I really like your solution. It helped me :). It can be also imporved with a more gneric regex for file matching: if ($request_filename !~* .[a-zA-Z0-9]+$ ) This should match any file.

server {
    # ... omissis ...

    # put this before your locations
    rewrite ^(/.*[^/])$ $1/ permanent;

    # ... omissis ...
}

If you want some kind of requests (say other than GET ones) to be prevented from doing this (usually it's about POST requests, as rewrite turns any request method into GET, which may break some of your site's dynamic functionality), add an if clause:

server {
    # ... omissis ...

    # put this before your locations
    if ($request_method = "GET" ) {
        rewrite ^(/.*[^/])$ $1/ permanent;
    }

    # ... omissis ...
}

You can also put the rewrite in a location block (if too), to make it more specific.

using the rewrites from anthonysomerset in a Wordpress, I experimented problems accesing to /wp-admin dashboard due to reirection loop. But i solve this problem using the above conditional:

if ($request_uri !~ "^/wp-admin")
{
rewrite ^([^.]*[^/])$ $1/ permanent;
rewrite ^([^.]*)$ /index.php;
}

This rule solves query string case too:

location ~ ^/([^.]*[^/])$ {
  if ($query_string) {
    return 301 $scheme://$host/$1/?$query_string;
  }
  return 301 $scheme://$host/$1/;
}

The regex has taken from @marc's answer: rewrite ^([^.\?]*[^/])$ $1/ permanent;

The extra slash ^/ in regex is added to improve readability

If nginx behind proxy with https, this snippet do correct redirect for $scheme

map $http_x_forwarded_proto $upstream_scheme {
    "https" "https";
    default "http";
}

server {
    ...
    location / {
        rewrite ^([^.\?]*[^/])$ $upstream_scheme://$http_host$1/ permanent;
    }
    ...
}

And on the upstream proxy pass the X-Forwarded-Proto header like:

location / {
    proxy_set_header X-Forwarded-Proto $scheme;
    ...
}

A less cpu intensive regex `[^/]$` that does the same job

# usage in rewrite 
rewrite [^/]$ $uri/ permanent;

# usage in location match and handling query string
location ~ [^/]$ {
    if ($query_string) {
      return 301 https://snapp.ir$uri/?$query_string;
     }
    return 301 https://snapp.ir$uri/;
}

rewrite regex runs before location matching and on our scale ( ~ 3 rps ) it demand an unusual amount of resources for an nginx pod; thus we use regex location which way more efficient in terms of cpu.

Try this: ^(.*)$ http://domain.com/$1/ [L,R=301]

This redirects (Status code 301) everything ($1) without a "/" to "$1/"

Gomez: You should absolutely 301 (redirect) the non-slashed URL to the slashed one, or search-engines and such will see example.com/blah and example.com/blah/ as two completely separate pages

Chris Over a year ago

I just tested this. ^(.*)$ redirects everything regardless. I had to use ^(.*)[^/] instead, so it only redirects if there's no ending slash.

This answer appears to provide syntax for Apache, but the original question is for nginx.
