flask-lambda-support
Write Flask applications that support being run in in AWS Lambda behind API Gateway.
This project was forked from: https://github.com/techjacker/flask-lambda
Improvements:
- Expose original input event from AWS on Flask's request object
- Production-grade logging
Requirements
- Python 3.6+
- Flask 0.10+
Installation
pip install flask-lambda-support
Usage
Here is an example of what a Flask app using this library would look like:
from flask_lambda import FlaskLambda
app = FlaskLambda(__name__)
@app.route('/foo', methods=['GET', 'POST'])
def foo():
data = {
'form': request.form.copy(),
'args': request.args.copy(),
'json': request.json
}
return (
json.dumps(data, indent=4, sort_keys=True),
200,
{'Content-Type': 'application/json'}
)
if __name__ == '__main__':
app.run(debug=True)You can access the original input event and context on the Flask request context:
from flask import request
assert request.aws_event['input']['httpMethod'] == 'POST'
assert request.aws_context.get_remaining_time_in_millis() == 10_000
