Wrap a WSGI application in an AWS Lambda handler function for running on API Gateway or an ALB.
A quick example:
from apig_wsgi import make_lambda_handler
from myapp.wsgi import app
# Configure this as your entry point in AWS Lambda
lambda_handler = make_lambda_handler(app)Installation
Use pip:
pip install apig-wsgiPython 3.4+ supported.
Usage
make_lambda_handler(app, binary_support=False)
app should be a WSGI app, for example from Django’s wsgi.py or Flask’s Flask() object.
If you want to support sending binary responses, set binary_support to True. ALB’s support binary responses by default, but on API Gateway you need to make sure you have '*/*' in the ‘binary media types’ configuration on your Rest API (whilst API Gateway supports a list of binary media types, using '*/*' is the best way to do it, since it is used to match the request ‘Accept’ header as well, which WSGI applications are likely to ignore).
Note that binary responses aren’t sent if your response has a ‘Content-Type’ starting ‘text/html’ or ‘application/json’ - this is to support sending larger text responses.
History
Pending Release
2.0.0 (2019-01-28)
Drop Python 2 support, only Python 3.4+ is supported now.
If exc_info is passed in, re-raise the exception (previously it would be ignored and crash in a different way). This isn’t the nicest experience, however the behaviour is copied from wsgiref's simple server, and most WSGI applications implement their own exception conversion to a “500 Internal Server Error” page already.
Noted that the EC2 ALB to Lambda integration is also supported as it uses the same event format as API Gateway.
1.2.0 (2018-05-14)
Work with base64 encoded body values in requests from API Gateway.
1.1.2 (2018-05-11)
Fix crash using binary support for responses missing a Content-Type header.
1.1.1 (2018-05-11)
Remove debug print()
1.1.0 (2018-05-10)
Add binary_support flag to enable sending binary responses, if enabled on API Gateway.
1.0.0 (2018-03-08)
First release on PyPI, working basic integration for WSGI apps on API Gateway.
