How to write nginx rewrite rule for replacing query param in query string

Question

folks!

We have following http request:

http://example.com/foo?redirect_uri=http%3A%2F%2Fexample.com%2Fbar

We want to replace redirect_uri from "example.com" to "example.net".

How to do it?

Thanks

You need to do it like this

location /foo {
   if ($args ~* "(.*)(example\.com)(.*)") {
       set $args "$1example.net$3";
       return 301 $scheme://$host$uri$is_args$args;
   }

}

Thanks, this also worked for me, but only after I added a try_files statement under the if-block to process the new URI. The location string matches both!

Missing a ? between $uri and $args should be return 301 $scheme://$host$uri?$args;
