Nginx rewrite unencodes url

Question

It seems Nginx it always un-encodes urls when used with a regular expression. I have a rewrite rule:

location /api/ {
    rewrite /api/(.*)$ $1 break;
    proxy_pass http://127.0.0.1:8000/$1;
}

I would like to remove the api from the usl but keep the rest of the path. Part of the path is an email address [email protected]. I am passing someone%40somewhere.com but Nginx is turning it back with the @ sign.

Answer 1

The correct answer seem to be

location /api/ {
        rewrite ^ $request_uri;
        rewrite ^/api/(.*) $1 break;
        return 400;
        proxy_pass http://127.0.0.1:8000/$uri;
    }

See Nginx pass_proxy subdirectory without url decoding for full answer and original author.
