Rails RSpec 请求规范失败，因为向重定向响应添加了意外的 %2F

Question

在 config/routes.rb 中：

get 'books(/*anything)' => redirect( "/public/%{anything}" ), :format => false

在 spec/requests/store_request_spec.rb 中：

get '/books/aoeu/snth'
expect(response).to redirect_to( '/public/aoeu/snth' )

这失败了：

Failure/Error: expect(response).to redirect_to( '/public/aoeu/snth' )
   Expected response to be a redirect to <http://www.example.com/public/aoeu/snth> but was a redirect to <http://www.example.com/public/aoeu%2Fsnth>.
Expected "http://www.example.com/public/aoeu/snth" to be === "http://www.example.com/public/aoeu%2Fsnth".
 # ./spec/requests/store_request_spec.rb:14:in `block (3 levels) in <top (required)>'

为什么 %2F 被插入到重定向响应中，我该如何防止它？

编辑：

如果我使用：

get 'books(/*anything)' => redirect( CGI::unescape("/public/%{anything}") ), :format => false

要创建一个未转义的字符串，我仍然会遇到同样的错误。

删除了旧答案，因为它没有帮助。这有效并经过测试：

在routes.rb:

get 'books/*anything', to: redirect { |params, request|
  path = CGI.unescape(params[:anything])
  "http://#{request.host_with_port}/public/#{path}"
}

在spec/requests/store_request_spec.rb:

describe "books globbed route" do
  before { get('/books/abcd/efgh') }
  it "routes to public" do

    expect(response).to redirect_to('/public/abcd/efgh')

  end
end

运行bundle exec rspec spec/requests/store_request_spec.rb # =>

Store
  books globbed route
    routes to public
