How to receive a JSON object with Rack

Question

I have a very simple Ruby Rack server, like:

app = Proc.new do |env| 
  req = Rack::Request.new(env).params
  p req.inspect 
  [200, { \'Content-Type\' =>         


        

Answer 1

One more way to do that:

# ...
request  = Rack::Request.new env
object   = JSON.parse request.body.gets
# ...

See the documentation: www.rubydoc.info/gems/rack/Rack/Lint/InputWrapper
