I am new to nginx. I have tried proxy_pass many times but cannot jump outside the site. Can nginx request external links?

Currently there is an external API interface address: http://122.23.21.212/api/v2?args=others&argc=4

Now I want to implement this function:

When I access http://localhost/myapi?args=others&args=4, nginx actually accesses the http://122.23.21.212/api/v2?args=others&argc=4 interface internally. Please tell me. How does this need to be configured?

shellserver {

    ...

    location /myapi {
        proxy_pass http://122.23.21.212/api/v2?$request_uri;
    }

    ...
}

Please help me, thank you
