How to set $args value in proxy_rewrite plugin

[huang-x-h]

Now, we want to change the $args value, append something

the nginx conf

location /ApiService/ {
    set $args "$args&appKey=secretKey";
    proxy_pass https://somepath.example.com/;
}

when user access http://ip:port/ApiService/getUser?userId=123, it will be proxy to https://somepath.example.com/getUser?userId=123&appKey=secretKey

then we use proxy_rewrite plugin

{
  "regex_uri": [
    "^/ApiService/(.*)",
    "/$1&appKey=secretKey"
  ]
}

but it just rewrite uri, not include the parameters, so how to implement parameter rewriting? use serverless plugin?

[huang-x-h]

It's fixed, see the proxy_rewrite source code, it will append parameter, so we change the conf

{
  "regex_uri": [
    "^/ApiService/(.*)",
    "/$1?appKey=secretKey"
  ]
}
