How to configure redirects to url with trailing slash in nginx?
This should solve the problem:
location / { if ($request_uri ~ ^([^.\?]*[^/])$) { return 301 $1/; } try_files $uri $uri/ /index.php$is_args$args;}
The query string begins at the ? and is not part of the normalized URI used when matching location and rewrite directives. The entire URI is available as the $request_uri variable. You could use your regular expression within an if block:
if ($request_uri ~ ^([^.?]*[^/])$ ) { return 301 $1/; }See this document for more, and this caution on the use of if.
I figured out how to do this without an if statement! This solves all the problems you mentioned (except case #2, and in case #3 it redirects but retains the query string).
# 301 try_file for trailing slashlocation ~ ^([^.\?]*[^/])$ { try_files $uri @addslash;}# 301 redirect for trailing slashlocation @addslash { return 301 $uri/$is_args$args;}# Root directory location handlerlocation / { try_files $uri/index.html $uri $uri/ /index.php?$query_string;}
