Flask-RESTful is an extension for Flask that adds support for quickly building REST APIs. It is a lightweight abstraction that works with your existing ORM/libraries. Flask-RESTful encourages best practices with minimal setup. If you are familiar with Flask, Flask-RESTful should be easy to pick up.
It’s time to write your first REST API. This guide assumes you have a working understanding of Flask, and that you have already installed both Flask and Flask-RESTful.
#!/usr/bin/python
from flask import Flask
from flask_restful import Api, Resource
app = Flask(__name__)
api = Api(app)
class DataSensorRestApi(Resource):
def get(self):
data = 'This is data from a sensor'
return data
api.add_resource(DataSensorRestApi, '/datasensor')
if __name__ == '__main__':
app.run(host='0.0.0.0', debug=True)
