やりたいこと

slackの投稿を整形する

前回のやり方では、一行メッセージのみが投稿可能だったので、attachmentを使ったものに置き換える。
そのために、slack-notifierを使用する

サンプルコード

slack.rb

require 'slack-notifier'

class SlackClient
  #
  def initialize(team, token, room='#general', name=nil)
    @client = Slack::Notifier.new(team, token)
    @default_room = room
    if name
      @client.username = name
      @default_name = name
    end
    clear_fields
  end
  #
  def clear_fields
    @client.channel = @default_room
    @fields = []
  end
  #
  def message(msg, room = nil)
    @client.channel = room if room
    @client.ping(msg)
    clear_fields
  end
  #
  def append_field(title, value, short = false)
    @fields << {:title => title, :value => value, :short => short}
  end
  #
  def format_message(msg, fields = [], room = nil)
    opts = {
      "fallback"  => msg,
      "color"     => "#8ABE00",
      "fields"    => @fields + fields,
    }
    @client.channel = room if room
    @client.ping(msg, attachments: [opts])
    clear_fields
  end

end

投稿部分のみ。前回のサンプルを参照してください。

sample.rb

#
def slack_send(slack, project, issue)
  action = (issue["created_on"] == issue["updated_on"]) ? "created" : "updated"
  #
  mes = "[" + project["name"] + "]" + issue['summary'] + "(" + issue['url'] + ") " + action
  mes_format = issue['summary']
  #
  slack.clear_fields
  slack.append_field("project", project["name"], true)
  slack.append_field("created by", issue['created_user']['name'], true)
  slack.append_field("priority", issue['priority']['name'], true)
  slack.append_field("url", issue['url'], true)
  room = project2room(project["name"])
  puts room
  if action == "created"
    slack.format_message(mes_format, [], room)
  else
    slack.message(mes, room)
  end
end

（中略）

  slack = SlackClient.new('test', 'xxxxxxxx', '#test', 'backlog')

（中略）

    slack_send(slack, project, issue)
