Flask Server
============
The following example shows how to set up a simple Flask server for which we receive HTTP Post requests forwarded by a Data Connector. Contained within each request is event data from your sensors, and the request is validated and decoded using functions provided by this package.

.. code-block:: python

   import os
   from flask import Flask, request  # pip install flask
   
   from dtintegrations import data_connector, provider
   
   app = Flask(__name__)
   
   
   @app.route('/', methods=['POST'])
   def print_request_contents():
       # Use the provider-specific validation function.
       payload = data_connector.HttpPush.from_provider(
           request=request,
           provider=provider.FLASK,
           secret=os.getenv('DT_SIGNATURE_SECRET'),
       )
   
       # Print the payload data.
       print(payload)
   
       # If all is well, return 200 response.
       return 'Success'
