Nginx pass_proxy subdirectory without url decoding

Question

I need to write an nginx location directive to proxy requests to subdirectory to another server preserving urlencoding and removing subdirectory pre

Answer 1

What you have to do is fairly easy as long as we are talking prefix matching with ^~ or no modifier

location /api/ {
  # if you don't want to pass /api/ add a trailing slash to the proxy_pass
  proxy_pass http://localhost:8080/;

  ...
}

And everything will be passed along without decoding, you don't have to pass $uri

Also while you use proxy pass you should also set these headers

# pass headers and body along
proxy_pass_request_headers on;
proxy_pass_request_body on;

# set some headers to make sure the reverse proxy is passing along everything necessary
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
