Add to_dict method for request headers

[antonpetrov145]

Hello, first of all thank you for this marvelous framework, it is really enjoyable to work with especially as I'm coming from Flask.

I noticed that there are methods for returning dictionaries for query parameters, path parameters and form data are also dictionaries. Suggestion is because currently we are losing the ability to set a default value if the header is missing, if it is - we get always None, but what if we need to have some default value?

My idea is to have something like this

request.headers.to_dict()

which will return a dictionary with all present headers

{
    "content-type": "application/json",
    "X-Forwarded-To": "some IP",
    ...
}

Is this possible to achieve?

Hey @antonpetrov145 👋

Thanks for opening an issue 😄 Yes, this can definitely be done. How does flask handle duplicate headers tho? i.e. the ones sharing the same name?

@sansyrox Happy New Year, awesome that you answered 😄

In flask when there is a header that is doubled

curl http://api:5000/ \-H 'X-Custom: somecustomvalue' \-H 'X-Custom: another'

running

request.headers.get("X-Custom")

flask returns both values separated by a comma

'somecustomvalue,another'
