Support array query params?

[yujiri8]

Many other frameworks, such as Django and FastAPI, support retrieving all values of a query param instead of assuming there's only one. Example (Kemal master):

require "kemal"
get "/" do |env|
  puts env.params.query["test"]
end
Kemal.run

Hit /?test=a?test=b.
See only "a".

Django and FastAPI provide ways to access all values assigned to the parameter as a list/array.

You need to use #fetch_all. E.g. puts env.params.query.fetch_all "test". Also be sure to fix your query params. The & separator should be used, not another ?.

Oh thanks, I didn't realize it was URI::Params in use.
