I’m making a post request using the built-in net/http ruby library, and I need to update it to post nested parameters.

Currently, I get (from another object) the params in the following format:

{ :user => {:code=>"00004812", :valid_from=>"2024-01-01"} }

But If I try to post them as is, the endpoint receives them as a string:

Parameters: {"user"=>"{"code"=>"00004812", "valid_from"=>"2024-01-01"}"

And they are not correctly parsed.

I tried to change them manually as:

{"user[code]" => "00004812", "user[valid_from]" => "2024-01-01"}

And, with this format, they are received correctly:

 Parameters: {"user"=>{"code"=>"00004812", "valid_from"=>"2024-01-01"}}

Is there a way to make the change programmatically without changing how the data is received from the other object?

My code looks like:

uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Post.new(uri.request_uri)
request.set_form_data(params)
response = http.request(request)
