javascript - Uncaught Error : Action is missing a listen method React/Reflux?

Question

我是 React Redux 新手。这是我正在开发的一个简单应用程序。但错误是我无法通过 Action 连接到商店。

这是我的错误

utils.js:78 Uncaught Error: action is missing a listen method

主题列表.js

    var React = require('react');
var Reflux = require('reflux');
var TopicStore = require('../stores/topic-store');
var Actions = require('../actions');

module.exports = React.createClass({
    mixins:[
      Reflux.listenTo(TopicStore,'onChange')  
    ],
    getInitialState:function () {
      return{
          topics:[]
      }
    },
    componentWillMount:function () {
       //Actions.getTopics()
        Actions.getTopics()
    },
    render:function () {
      return <div className="list-group">
          ToPic List
          {this.renderTopics()}
      </div>
    },
    renderTopics:function () {

        return this.state.topics.map(function(topic) {
            return <li key={topic.id}>
                {topic.description}
            </li>

        })

    },
    onChange:function (evet,topics) {
        this.setState({topics:topics})
    }


});

actions.js

var Reflux = require('reflux');

module.exports = Reflux.createAction([
    'getTopics',

]);

主题商店.js

    var Api = require('../utils/api');
var Reflux = require('reflux');
var Actions = require('../actions');


module.exports = Reflux.createStore({
    listenables:[Actions],
   getTopics:function () {
       return Api.get('topics/defaults')
           .then(function (json) {
               this.topics = json.data;
               this.triggerChange();
           }.bind(this));
   },
    con:function () {
      console.log('Working')
    },
    triggerChange:function () {
        this.trigger('change',this.topics)

    }
});

错误消息意味着您正在尝试收听无法收听的内容(即它没有监听方法。)

这意味着错误的来源可能是:

1. listenables:[Actions]来自topic-store.js
2. Reflux.listenTo(TopicStore,'onChange')来自topic-list.js

我相信是前者，因为actions.js中有一个拼写错误。 ，方法为 Reflux.createActions ，不是Reflux.createAction 。
