Retrieve lambda event object on FastAPI

I use mangum with FastAPI. Also, I often create an app which authenticates the request by Cognito

I want to obtain a few Cognito information(eg: cognitoIdentityPoolId ) from lambda event because I must use the information for business logic on API. (https://docs.aws.amazon.com/lambda/latest/dg/with-on-demand-https.html)

Unfortunately, Mangum doesn’t pass the raw lambda event object to a function(controller). Is there a way to retrieve an event object of lambda? Or, Could you please implement it? Btw, I don’t know how to pass it to a function 😕

@koxudaxi I’ve merged the changes into master. Here is an example of how you can access the event and context using FastAPI:

from fastapi import FastAPI
from starlette.requests import Request

app = FastAPI()


@app.get("/")
def hello_world(request: Request):
    return {"aws": request.scope["aws"]}

@erichonkanen yeah, there is definitely some work needed on the docs. There is an open issue for documentation generally https://github.com/erm/mangum/issues/48.

I’ll try to get to it at some point, but open to PRs as well. 😃
