# This is a simplified example that only support GET request.
# It is meant to help you to get you started if you're new to development
# and to show how simple is using Azure SQL with Python
# A more complete example is in "app.py"
# To run this simplified sample follow the README, but instead of running "flask run"
# just run "python ./simple-app.py"
# Enjoy!

# Initialize Flask
app = Flask(__name__)

# Setup Flask Restful framework
api = Api(app)
parser = reqparse.RequestParser()
parser.add_argument('customer')

# Create connection to Azure SQL
conn = pyodbc.connect(os.environ['SQLAZURECONNSTR_WWIF'])

# Customer Class
class Customer(Resource):
    def get(self, customer_id):     
        customer = {"CustomerID": customer_id}
        cursor = conn.cursor()    
        cursor.execute("EXEC web.get_customer ?", json.dumps(customer))
        result = json.loads(cursor.fetchone()[0])        
        cursor.close()
        return result, 200
    
# Create API route to defined Customer class
api.add_resource(Customer, '/customer', '/customer/<customer_id>')
