;;; Commentary:
;;; This file is effectively a common-use wrapper for
;;; `sx-request-make'. It provides higher-level handling such as
;;; (authentication, filters, ...) that `sx-request-make' doesn't need
;;; to handle.
;;; Code:
(require 'json)
(require 'url)
(require 'sx)
(require 'sx-auth)
(require 'sx-request)
(require 'sx-filter)
(cl-defun sx-method-call (method &key id
submethod
keywords
(filter 'none)
auth
(url-method "GET")
site)
"Call METHOD with additional keys.
:ID is the id associated with a question, answer, comment, post or
user.
:SUBMETHOD is the additional segments of the method.
:KEYWORDS are the api parameters.
:FILTER is the set of filters to control the returned information
:AUTH defines how to act if the method or filters require
authentication.
:URL-METHOD is either \"POST\" or \"GET\"
:SITE is the api parameter specifying the site.
Return the entire response as a complex alist."
(let ((access-token (sx-cache-get 'auth))
(method-auth (sx-auth--method-p method submethod))
(filter-auth (sx-auth--filter-p filter))
