AWS Requests Auth

David Muller, the author of Intuitive Python pointed me at this handy snippet of code. Thanks Richard Boyd!

import boto3
from botocore.auth import SigV4Auth
from botocore.awsrequest import AWSRequest
import requests

session = boto3.Session()
credentials = session.get_credentials()
creds = credentials.get_frozen_credentials()

def signed_request(method, url, data=None, params=None, headers=None):
    request = AWSRequest(method=method, url=url, data=data, params=params, headers=headers)
    # "service_name" is generally "execute-api" for signing API Gateway requests
    SigV4Auth(creds, "service_name", REGION).add_auth(request)
    return requests.request(method=method, url=url, headers=dict(request.headers), data=data)

def main():
    url = f"my.url.example.com/path"
    data = {"environmentId": self._environment_id}
    headers = {'Content-Type': 'application/x-amz-json-1.1'}
    response = signed_request(method='POST', url=url, data=data, headers=headers)

if __name__ == "__main__":
