如何断开通道控制器内的 ActionCable 连接？

Question

有什么方法可以断开 ActionCable 与通道控制器的连接吗？

我试过从 subscribed 方法到 return 但它没有关闭连接

class MyChannel < ApplicationCable::Channel
  def subscribed
    ####
    return unless condition
    ####
    stream_from "mychannel_#{params[:id]}"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

Answer 1

找到了使用reject的方法

class MyChannel < ApplicationCable::Channel
  def subscribed
    ####
    unless condition do
      reject
      return
    end
    ####
    stream_from "mychannel_#{params[:id]}"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end
