Retrieve lambda event object on FastAPI

[koxudaxi]

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 😕

I'm working on a PR that will include the event and context objects in the ASGI scope. I'll reference this issue when I push the changes.

@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"]}

Thank you very much!!

greetings, just stumbled upon this, definitely would be helpful to have it in the main readme doc on the front page! went to access the apigateway event.requestContext.authorizor data and realized I didn't know how to get it :)

Thanks for the pr!

@erichonkanen yeah, there is definitely some work needed on the docs. There is an open issue for documentation generally #48.

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

It was changed to:
request.scope["aws.event"]

Still no documentation about it
