docs: Fetches the given relative API path, e.g., "/btaylor/picture"
  
          If the request is a POST, ``post_args`` should be provided. Query
          string arguments should be given as keyword arguments.

          Many methods require an OAuth access token which you can
          obtain through `~OAuth2Mixin.authorize_redirect` and
          `get_authenticated_user`. The user returned through that
          process includes an ``access_token`` attribute that can be
          used to make authenticated requests via this method.
  
          Example usage:
  
          .. testcode::
  
              class MainHandler(tornado.web.RequestHandler,
                                tornado.auth.FacebookGraphMixin):
                  @tornado.web.authenticated
                  async def get(self):
                      new_entry = await self.facebook_request(
                          "/me/feed",
                          post_args={"message": "I am posting from my Tornado application!"},
                          access_token=self.current_user["access_token"])
  
                      if not new_entry:
                          # Call failed; perhaps missing permission?
                          yield self.authorize_redirect()
                          return
                      self.finish("Posted a message!")
  
          .. testoutput::
             :hide:
  
          The given path is relative to ``self._FACEBOOK_BASE_URL``,
          by default "https://graph.facebook.com".
  
          This method is a wrapper around `OAuth2Mixin.oauth2_request`;
          the only difference is that this method takes a relative path,
          while ``oauth2_request`` takes a complete url.
  
          .. versionchanged:: 3.1
             Added the ability to override ``self._FACEBOOK_BASE_URL``.
  
          .. versionchanged:: 6.0
  
             The ``callback`` argument was removed. Use the returned awaitable object instead.
