完整的例子

假设我们有容器 CustomersContainer，它将 Customers 哑组件连接到 Redux 商店。

在 index.js 中：

import { Component }, React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import { createStore } from 'redux';
import rootReducer from './redux/rootReducer';
import CustomersContainer from './containers/CustomersContainer';

let store = createStore(rootReducer);

render(
  <Provider store={store}>
    <CustomersContainer />
  </Provider>,
  document.getElementById('root')
);

在 CustomersContainer 中：

import React, { Component } from 'react';
import { connect } from 'react-redux';

// Import action creators
import { fetchCustomers } from '../redux/actions';

// Import dumb component
import Customers from '../components/Customers';

// ES6 class declaration
class CustomersContainer extends Component {
  componentWillMount() {
    // Action fetchCustomers mapped to prop fetchCustomers
    this.props.fetchCustomers();
  }

  render() {
    return <Customers customers={this.props.customers} />;
  }
}

function mapStateToProps(state) {
  return {
    customers: state.customers
  };
}

// Here we use the shorthand notation for mapDispatchToProps
// it can be used when the props and action creators have the same name 
const CustomersContainer = connect(mapStateToProps, { fetchCustomers })(CustomersContainer);

export default CustomersContainer;
