我正在处理react-redux示例:https://github.com/timscott/react-devise-sample

正在setup.js中创建redux商店,如下所示:https://github.com/timscott/react-devise-sample/blob/master/client/src/app/setup.js

关键部分:

const initStore = ({onRehydrationComplete}) => {
  store = createStore(
    combineReducers({
      ...reactDeviseReducers,
      cats: [],
      form: formReducer,
      router: routerReducer,
      apollo: apolloClient.reducer()
    }),
    {},
    compose(
      applyMiddleware(
        thunk,
        routerMiddleware(history),
        apolloClient.middleware()
      ),
      autoRehydrate()
    )
  );

  persistStore(store, {
    blacklist: [
      'form'
    ]
  }, onRehydrationComplete);

  return store;
};

在反应组件中的此文件之外: CatsPage.js

我正在尝试.dispatch(loadCats()),以便反应应用程序将从服务器获取猫的列表,更新商店,并神奇地更新dom。这是我在CatsPage.js中的内容:

import React from 'react';
import PropTypes from 'prop-types';
import {connect} from 'react-redux';
import CatList from './CatList';
import {loadCats} from '../../actions/catActions';
import {initStore} from '../../app/setup';

class CatsPage extends React.Component {
  state = {
    rehydrated: false
  };
  componentDidMount() {
    initStore.dispatch(loadCats())
  }
  render() {
    return (
      <div>
        <h1>Cats</h1>
        <div>
          <CatList cats={this.props.cats} />
        </div>
      </div>
    );
  }
}

CatsPage.propTypes = {
  cats: PropTypes.array.isRequired
};

function mapStateToProps(state, ownProps) {
  return {
    cats: state.cats
  };
}

export default connect(mapStateToProps)(CatsPage);

我收到错误:Uncaught TypeError: _setup.initStore.dispatch is not a function

我是react-redux初学者。

更新

CatList.js

import React from 'react';
import PropTypes from 'prop-types';
import {Link} from 'react-router-dom';

const CatList = ({cats}) => {
  return (
      <ul className="list-group">
        {cats.map(cat =>
           <li className="list-group-item" key={cat.id}>
            <Link to={'/cats/' + cat.id}>{cat.name}</Link>
           </li>
        )}
      </ul>
  );
};

CatList.propTypes = {
  cats: PropTypes.array.isRequired
};

export default CatList;

我假设您已正确设置了提供商。如果这样正确的方式来访问调度方法就是道具。所以你可以这样做。

this.props.dispatch(loadCats())
