Rails Action Cable没有收到数据？订阅模特

Question

我正在尝试Rails 5的动作电缆功能。 如果我尝试使用rake任务进行广播，则表示我没有收到消息。 有谁看到这个问题？正在建立联系。 非常感谢你。

channel.rb

module ApplicationCable
  class Channel < ActionCable::Channel::Base


    def connect
      self.current_user = find_verified_user
    end

    private
    def find_verified_user
      if current_user
         return current_user
      else
        reject_unauthorized_connection
      end
    end

  end
end

FileStatusChannel.rb

class FileStatusChannel < ApplicationCable::Channel
  def subscribed
    matching_job = MatchingJob.find_by_uuid(params[:file_uuid])
    stream_for matching_job
  end
end

的Javascript

<script>
        // Action Cable
        (function() {
            this.App || (this.App = {});

            App.cable = ActionCable.createConsumer();
        }).call(this);

        App.cable.subscriptions.create({
            channel: "FileStatusChannel",
            file_uuid: "18e01f4e-1d20-4905-b713-9ddc7adc4ae0",
            received: function(data) {
                console.log(data);
            }
        });
</script>

佣金任务

matching_job = MatchingJob.find_by_uuid("18e01f4e-1d20-4905-b713-9ddc7adc4ae0")
FileStatusChannel.broadcast_to(matching_job, {hello: "test"})
