====================================================
Flask ASK SDK - Extending ASK SDK to work with Flask
====================================================
**flask-ask-sdk** is the extension package, that will let skill developers
use `ASK SDK <https://developer.amazon.com/docs/alexa-skills-kit-sdk-for-python/overview.html>`__
package in their Flask application. It provides an easy way to register and
use `skills as custom webservices <https://developer.amazon.com/docs/custom-skills/host-a-custom-skill-as-a-web-service.html>`__.
Quick Start
-----------
If you already have a skill built using the ASK SDK skill builders, then you
only need to do the following, to set this up in your flask app:
.. code-block:: python
from flask import Flask
from ask_sdk_core.skill_builder import SkillBuilder
from flask_ask_sdk.skill_adapter import SkillAdapter
sb = SkillBuilder()
# Register all handlers, interceptors etc.
# For eg : sb.add_request_handler(LaunchRequestHandler())
app = Flask(__name__)
skill_response = SkillAdapter(
skill=sb.create(), skill_id=<YOUR_SKILL_ID>, app=app)
skill_response.register(app=app, route="/")
if __name__ == '__main__':
app.run()
Are you planning to deploy your skill on AWS Lambda? Then, you don't even
need this package. The `ASK SDK` provides a `lambda_handler` that can be
directly used in your lambda console.
More code examples can be found `here <https://developer.amazon.com/docs/alexa-skills-kit-sdk-for-python/sample-skills.html>`__.
Features
--------
- Works as an extension on skills built using ASK SDK. No need to learn
something new.
- Provides default request signature and request timestamp verification.
These can be configured on app level by setting / unsetting app
configuration.
- Provides a way to register multiple skills on your app, at different
endpoints.
Installation
------------
.. important::
`cryptography` is a dependency for this package. If you have not
already installed
`cryptography <https://cryptography.io/en/latest/>`_, you might need to
install additional prerequisites as detailed in the
`cryptography installation guide <https://cryptography.io/en/latest/installation/>`_
for your operating system.
Assuming that you have Python and ``virtualenv`` installed, you can
install the package and it's dependencies (``ask-sdk-webservice-support``,
``flask``) from PyPi as follows:
.. code-block:: sh
$ virtualenv venv
$ . venv/bin/activate
$ pip install flask-ask-sdk
This package is **not** installed along-side `ask-sdk` standard distribution,
and has to be installed separately if you need support for skill
deployment as webservice, using Flask.
SDK Usage and Getting Started
-----------------------------
Getting started guides, SDK Features, API references, samples etc. can
be found in the `technical documentation <https://developer.amazon.com/docs/alexa-skills-kit-sdk-for-python/overview.html>`_
