Uploading XML-file results in Rack::QueryParser::InvalidParameterError

[wuarmin]

Hello,
this works in past rack-versions, but if I try to upload a XML file to a rack 2.2.4 app, I get a
Rack::QueryParser::InvalidParameterError

<!--/tmp/test/test.xml-->
<root>
  <name>100 % Meijer</name>
</root>

curl -F 'file=@/tmp/test/test.xml' http://localhost:2300/test/upload

I get following error

Rack::QueryParser::InvalidParameterError: invalid %-encoding

The Content-Type is multipart/form-data. Changing it to application/xml does not change anything.

Here's a spec which shows the behavior

# frozen_string_literal: true

require "hanami/middleware/body_parser"
require "hanami/router"
require "rack/builder"
require "rack/test"
require "json"

RSpec.describe "post xml behavior" do
  include Rack::Test::Methods
  let(:app) do
    r = router
    Rack::Builder.new do
      # use Hanami::Middleware::BodyParser, :json
      run r
    end
  end

  let(:router) do
    Hanami::Router.new do
      post "/upload-xml", to: ->(_env) { [200, {}, ["resources/:id"]] }
    end
  end

  it "responds to /upload-xml" do
    post "/upload-xml", "<root><name>100% Meijer</name></root>", "CONTENT_TYPE" => "multipart/form-data"
    expect(last_response.status).to eq(200)
  end
end

The same happens to a JSON-post. Please checkout this issue: hanami/router#237

Thanks

As pointed out in hanami/router#237 (comment), this is a Hanami bug.
