Returning only a response code

[madflier]

I've been writing a small app (Auth framework for nginx) which has a number of routes which meaningfully return only a response code (eg 200 or 403).

Very foolishly, I got a little stuck, having assumed that I could return 200 from a route, and accept that the documentation is pretty clear that a text or bytes content is needed as the first value, with the response code being the second returned value in order to achieve what I am attempting, if I don't want to create a response object myself.

Thusly return "foo", 200 is entirely suitable for my requirements.

However, I did wonder if:

a) A single return value of an integer could be accepted as the response code, with an empty body

b) The error returned in such a situation could be improved (it does declare that a bytes object was expected rather than an int, but this error could be caught earlier and more clearly to the less savvy programmer).

I further accept that very few people will be wanting to sent empty responses with manipulation of only the response code.

However, such is my suggestion today.

Thanks as always, Miguel.

The normal way you return an empty response is with return "", 200. There is no need for the text to have any characters, it can be an empty string.

I think it is feasible to support return 200 as an alias to return "", 200, I'll look into it.

Perfect, thank you for considering it.
