Feature request: Add Event Source Data Class for AWS Lambda Function URLs
See original GitHub issueUse case
With the general availability of AWS Lambda Function URLs to implement microservices AWS Lambda Powertools for Python should support this event type.
While I can not find a formal definition of what the event can look at, here is a sample:
{'version': '2.0', 'routeKey': '$default', 'rawPath': '/favicon.ico', 'rawQueryString': '', 'headers': {'sec-fetch-mode': 'no-cors', 'referer': 'https://c3zn6zdoafuxiztw6peqnbnflm0mywcm.lambda-url.us-east-1.on.aws/', 'sec-fetch-site': 'same-origin', 'accept-language': 'en-US,en;q=0.9', 'x-forwarded-proto': 'https', 'x-forwarded-port': '443', 'x-forwarded-for': '98.164.126.35', 'accept': 'image/avif,image/webp,image/apng,image/svg+xml,image/*,*/*;q=0.8', 'sec-ch-ua': '\" Not A;Brand\";v=\"99\", \"Chromium\";v=\"100\", \"Google Chrome\";v=\"100\"', 'sec-ch-ua-mobile': '?0', 'x-amzn-trace-id': 'Root=1-6260d9a0-4156ec632c4ba12352c4ff3a', 'sec-ch-ua-platform': '\"Linux\"', 'host': 'c3zn6zdoafuxiztw6peqnbnflm0mywcm.lambda-url.us-east-1.on.aws', 'accept-encoding': 'gzip, deflate, br', 'sec-fetch-dest': 'image', 'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.75 Safari/537.36'}, 'requestContext': {'accountId': 'anonymous', 'apiId': 'c3zn6zdoafuxiztw6peqnbnflm0mywcm', 'domainName': 'c3zn6zdoafuxiztw6peqnbnflm0mywcm.lambda-url.us-east-1.on.aws', 'domainPrefix': 'c3zn6zdoafuxiztw6peqnbnflm0mywcm', 'http': {'method': 'GET', 'path': '/favicon.ico', 'protocol': 'HTTP/1.1', 'sourceIp': '98.164.126.35', 'userAgent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.75 Safari/537.36'}, 'requestId': '1e5fa2e6-65a2-474a-96f6-4c9858b0943f', 'routeKey': '$default', 'stage': '$default', 'time': '21/Apr/2022:04:12:16 +0000', 'timeEpoch': 1650514336041}, 'isBase64Encoded': False}
Please note that the path to the lambda is effectively /*.
