Description

Hi, I have to call an upstream server with encoded string.

For example,
I want to make a request like this.

curl -X GET "{apisix-server-address}/rest/alimi/alimianswer/1234/N/%ED%85%8C%EC%8A%A4%ED%8A%B8"

(%ED%85%8C%EC%8A%A4%ED%8A%B8 is encoded string)

I've found out that the apisix uses decoded URI coming from nginx through this
So, i've tried using use_real_request_uri_unsafe option, but it doesn't work with regex_uri.

Is there any way to call the upstream server with encoded string?

Here's my configuration.

- name: proxy-rewrite
  enable: true
	config:
		regex_uri:
			- /rest/alimi/alimianswer/(.+)/(.+)/(.+)
			- /cv/v1/emergency/answer?emerNtceSeq=$1&confirmYn=$2&answerCtnt=$3
    use_real_request_uri_unsafe: true

When I used the above configuration, the log result were like this

10.205.164.68 - - [12/Jun/2023:04:42:21 +0000] .... "GET /rest/alimi/alimianswer/1234/N/%ED%85%8C%EC%8A%A4%ED%8A%B8 HTTP/1.1" 400 808 0.077 "-" "curl/7.79.1" - - - "http://{upstream-server}"

What I want is to call the upstream server with below url

http://{upstream-server}/cv/v1/emergency/answer?emerNtceSeq=1234&confirmYn=N&answerCtnt=%ED%85%8C%EC%8A%A4%ED%8A%B8
