Just an experiment with Sinatra and DataMapper to make a RESTful/JSON web service.

Run the application

foreman start

Tests

Run the tests

rake runs the whole testsuite.

Testing with CURL

Here are a couple of example REST requests using curl:

curl -i -H "Accept: application/json" http://localhost:4567/services
curl -i -H "Accept: application/json" http://localhost:4567/services/1
curl -i -H "Accept: application/json" http://localhost:4567/services/2

curl -i -H "Accept: application/json" -X POST -d "service[title]=Curl&service[posted_by]=curl" http://localhost:4567/services/new
curl -i -H "Accept: application/json" -X PUT -d "service[title]=Curly" http://localhost:4567/services/1

curl -i -H "Accept: application/json" -X POST -d "comment[text]=Yop&comment[posted_by]=Me" http://localhost:4567/services/2/comments/new

curl -i -H "Accept: application/json" -X POST -d "" http://localhost:4567/services/1/up
curl -i -H "Accept: application/json" -X POST -d "" http://localhost:4567/services/1/down
curl -i -H "Accept: application/json" -X POST -d "" http://localhost:4567/services/1/close

curl -i -H "Accept: application/json" -X GET http://localhost:4567/services/2/comments
curl -i -H "Accept: application/json" -X GET http://localhost:4567/services/2/comments/1
curl -i -H "Accept: application/json" -X DELETE http://localhost:4567/services/2/comments/1
