小编Mar*_*ria的帖子

当我运行我的react-native移动应用程序时,服务器说它连接到PostChannel.它会创建帖子,但是我在"收到"函数中没有得到任何响应,所以它不会实时更新.

这是我的反应原生代码:

import ActionCable from 'react-native-actioncable';
const APP = {};
APP.cable = ActionCable.createConsumer("http://localhost:3000/cable");

const addSocket = (dispatch) => {
  const self = this;
  this.subscription = APP.cable.subscriptions.create(
    "PostChannel",
  {
    connected: () => {
      console.log("connected: action cable");
    },
    disconnected: () => {
      console.log("disconnected: action cable");
    },
    received: (data) => {
      console.log('received', data);     // no response here
      dispatch(receivePost(data.post));
    }
  });
};

Rails代码:

渠道

class PostChannel < ApplicationCable::Channel
  def subscribed
    stream_from "post_channel"
  end
end

模型

class Post < ApplicationRecord
  validates :user_id, :venue_id, presence: true …
