Purpose
=======
A Library for setting up login routes in a Chalice app.
Basic Usage
===========
Below is an example of a basic application making use of a Cognito User Pool.
First set up a new Chalice app::
$ chalice new-project test-auth
$ cd test-auth
Next we add ``chalice-cognito-auth`` as a dependency::
$ echo "chalice-cognito-auth" >> requirements.txt
Now update the ``app.py`` file to configure a default user pool handler.
.. code:: python
from chalice import Chalice
import chalice_cognito_auth
app = Chalice(app_name='test-auth')
app.experimental_feature_flags.update([
'BLUEPRINTS',
])
user_pool_handler = chalice_cognito_auth.default_user_pool_handler()
app.register_blueprint(user_pool_handler.blueprint)
@app.route('/whoami', authorizer=user_pool_handler.auth)
def index():
return {
'username': user_pool_handler.current_user
}
This will create a ``UserPoolHandler`` object using the environment variables
``APP_CLIENT_ID`` for the Cognito Userpool application client id. ``POOL_ID``
for the ID of the Cognito Userpool itself. And ``AWS_REGION`` for the
region. ``AWS_REGION`` is set by the AWS Lambda runtime, but the other two we
need to set ourselves. Update the file ``.chalice/config.json`` to look
something like the following::
{
"version": "2.0",
"app_name": "test-auth",
"environment_variables": {
"APP_CLIENT_ID": "...client id here...",
"POOL_ID": "...pool id here..."
},
"stages": {
"dev": {
"api_gateway_stage": "api"
}
}
}
Substitute the client id and pool id values for ones that match an existing
cognito user pool you have and can use for testing.
Now deploy the application using::
$ chalice deploy
Creating deployment package.
Updating policy for IAM role: test-auth-dev
Updating lambda function: test-auth-dev
Updating lambda function: test-auth-dev-UserPoolAuth
Updating rest API
Resources deployed:
- Lambda ARN: arn:aws:lambda:us-west-2:...:function:test-auth-dev
- Lambda ARN: arn:aws:lambda:us-west-2:...:function:test-auth-dev-UserPoolAuth
- Rest API URL: https://id.execute-api.us-west-2.amazonaws.com/api/
Now that it has been deployed we can access the API using the Rest API
URL. chalice-cognito-auth injects a ``login`` route which accepts a ``POST``
request with a JSON payload containing the two keys ``username`` and
``password``. Make sure your configured userpool has a user in it that can be
used for testing and send something like the following::
$ curl -X POST -H Content-Type:application/json https://id.execute-api.us-west-2.amazonaws.com/api/login -d '{"username":"StealthyCoin", "password": "secret"}'
{"id_token":"...","refresh_token":"...","access_token":"...","token_type":"Bearer"}
The above JSON response contains all the tokens needed to send authorized
requests. To test our authorizer we will use the ``whoami`` route which simply
takes a request and either rejects it if unauthorized, or sends back the
username associated with the request. To do this we will send a ``GET`` request
with an ``Authorization`` header with the value of our ``id_token`` from the
result JSON above.
In my case::
$ curl -H Authorization:...id token here... https://id.execute-api.us-west-2.amazonaws.com/api/whoami
{"username":"StealthyCoin"}
Which sends back JSON object with the username that goes with my id token.
To check that a requset with a bad authorization token is rejected, run the
following curl command::
$ curl -H Authorization:foobar https://id.execute-api.us-west-2.amazonaws.com/api/whoami
{"Message":"User is not authorized to access this resource"}
