Allow redirects for requests

[gar1t]

Are you aware of any issues when supporting redirects from the Discourse server? In your call to requests.request() you explicitly set allow_redirects to False. This prevents topic lookup by path only (omitting the ID).

I think a number of functions could make ID optional using the server redirect to resolve as needed.

I'm not aware of any, it was added here 0cef55a probably because it seemed sensible?

Don't see any reasons why this couldn't be changed.

I'm working on a fork atm and will try to apply this redirect support where I can spot opportunities. E.g. client.topic(slug) where id can be omitted seems to work. When I have something presentable I'll open a PR for review.

I've created a PR that takes a swing at allowing redirects for certain methods #34 .

I found this issue with client.category_topics(id) as /c/{id}.json now redirects to /c/{category_slug}.json.

My PR implements this by allowing request_kwargs to be passed to the HTTP verb methods, which pass it along to client._request where they can override the default keyword arguments for request.request.
