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

It seems that I'm supposed to use something like:

msg = JSON.parse env['rack.input'].read 

Then just use params in the msg hash.

At least it worked for me this way.
