Avoid nginx escaping query parameters on proxy_pass

问题

I to proxy /api on a domain, I have this location block.

location ^~ /api/ {
    rewrite_log on;
    rewrite ^/api/(.*) /$1$is_args$args break;
    proxy_pass http://127.0.0.1:1337;
}

It works fine as long as the URLs do not have query parameters, but as soon as they do, I get errors on the upstream server like these Could not find path: /records%3fname=hoegh.io

The %3f in question here is an URL encoded ?, and since it's URL encoded, the upstream server does not recognize it. That might be retarded, but I was hoping it was possible to get nginx to handle this correctly (ie. not escape the URL before passing it to the proxy).

Any ideas?

You don't need to do anything. $args is passed along automatically.

If you wish to modify the $args that are passed you have to override.

set $args "foo=bar";

for instance.

Working solution should go as follows:

location ^~ /api/ {
    rewrite_log on;
    rewrite ^/api/(.*) /$1 break;
    proxy_pass http://127.0.0.1:1337;
}

Have you tried this instead? It's generally not needed to add the query string as Nginx adds it automatically:

rewrite ^/api/(.*) /$1? break;
