    module Agents class DropboxFileUrlAgent < Agent include DropboxConcern cannot_be_scheduled! no_bulk_receive! description <<-MD The _DropboxFileUrlAgent_ is used to work with Dropbox. It takes a file path (or multiple files paths) and emits events with either [temporary links](https://www.dropbox.com/developers/core/docs#media) or [permanent links](https://www.dropbox.com/developers/core/docs#shares). #{'## Include the `dropbox-api` and `omniauth-dropbox` gems in your `Gemfile` and set `DROPBOX_OAUTH_KEY` and `DROPBOX_OAUTH_SECRET` in your environment to use Dropbox Agents.' if dependencies_missing?} The incoming event payload needs to have a `paths` key, with a comma-separated list of files you want the URL for. For example: { "paths": "first/path, second/path" } __TIP__: You can use the _Event Formatting Agent_ to format events before they come in. Here's an example configuration for formatting an event coming out of a _Dropbox Watch Agent_: { "instructions": { "paths": "{{ added | map: 'path' | join: ',' }}" }, "matchers": [], "mode": "clean" } An example of usage would be to watch a specific Dropbox directory (with the _DropboxWatchAgent_) and get the URLs for the added or updated files. You could then, for example, send emails with those links. Set `link_type` to `'temporary'` if you want temporary links, or to `'permanent'` for permanent ones. MD event_description <<-MD The event payload will contain the following fields: { "url": "https://dl.dropboxusercontent.com/1/view/abcdefghijk/example", "expires": "Fri, 16 Sep 2011 01:01:25 +0000" } MD def default_options { 'link_type' => 'temporary' } end def working? !recent_error_logs? end def receive(events) events.flat_map { |e| e.payload['paths'].split(',').map(&:strip) } .each do |path| create_event payload: (options['link_type'] == 'permanent' ? permanent_url_for(path) : temporary_url_for(path)) end end private def temporary_url_for(path) dropbox.find(path).direct_url end def permanent_url_for(path) result = dropbox.find(path).share_url({ :short_url => false }) result.url = result.url.gsub('?dl=0','?dl=1') # cause the url to point to the file, instead of to a preview page for the file result end end end
