Add oauth support

[lucaspiller]

Twitter will be removing HTTP basic authentication from the streaming API at the beginning of June.

WIP in the oauth branch.

Any news about this feature?

Thanks.

Ping, any update on this?

[lucaspiller]

No it isn't complete yet, you can see WIP so far which is basically just refactoring the existing code to allow different authentication schemes. If you already have the oAuth token, all that is required to use it is extend the method that generates the request headers:

twerl/src/stream_client_util.erl

Lines 13 to 16 in 729cb64

	% TODO extend for oauth
	-spec headers_for_auth(term(), term(), list()) -> list().
	headers_for_auth({basic, [User, Pass]}, _Endpoint, _Params) ->
	generate_auth_headers(User, Pass).

I haven't had time to work on this recently, however PRs are appreciated :)

[arjan]

Yup, working on a PR as we speak :) In a few days I'll have something.

@lucaspiller what kind of local server are you testing again for espec?

[lucaspiller]

Good question. I'll have a look and see if I can figure it out...
