How to parse JSON request body in Sinatra just once and expose it to all routes?

Question

I am writing an API and it receives a JSON payload as the request body.

To get at it currently, I am doing something like this:

post \'/doSomething\'         


        

Answer 1

before do
  request.body.rewind
  @request_payload = JSON.parse(request.body.read, symbolize_names: true)
end

So you can also symbolize_names while parsing JSON request body, this will give you access to your nested params like this @request_payload[:user]
