    # encoding: utf-8 module Agents class WeiboPublishAgent < Agent include WeiboConcern cannot_be_scheduled! description <<-MD The Weibo Publish Agent publishes tweets from the events it receives. #{'## Include `weibo_2` in your Gemfile to use this Agent!' if dependencies_missing?} You must first set up a Weibo app and generate an `access_token` for the user that will be used for posting status updates. You'll use that `access_token`, along with the `app_key` and `app_secret` for your Weibo app. You must also include the Weibo User ID (as `uid`) of the person to publish as. You must also specify a `message_path` parameter: a [JSONPaths](http://goessner.net/articles/JsonPath/) to the value to tweet. Set `expected_update_period_in_days` to the maximum amount of time that you'd expect to pass between Events being created by this Agent.
