reading parameters on Sinatra post

Question

I\'m working on my first Sinatra app and I have an hard time getting parameters from a post request.

I\'m using MiniTest::Spec and my spec looks like

 pa         


        

Answer 1

Sinatra just doesn't parse this data, because they are not form parameters.

Form parameter would look like this

curl -X POST 127.1:4567/ -d "foo=bar"

Instead of params you can just use request.body.read or use rack contrib.

rack-contrib

1. Install it with gem install rack-contrib
2. require it

require 'rack'

require 'rack/contrib'

3. load it use Rack::PostBodyContentTypeParser

with this you can use params as normal for json post data. Something like this:

curl -X POST -H "Content-Type: application/json" -d '{"payload":"xyz"}' 127.1:4567/
