React router v4不能与Redux一起使用

Question

使用React router v4开发React应用程序.一切顺利,直到我在我的应用程序中介绍了Redux.从那以后点击链接更改路由,浏览器URL会发生变化,但是路径对应的组件没有加载.如果我注释掉Redux代码,它会很好用.可能是什么导致了这个？这是我的路由代码:

import React, { Component } from 'react';
import { Switch, Route, Link } from 'react-router-dom';
import LeftSubDefault from './../components/left-sub-default.component';
import LeftSubOne from './../components/left-sub-one.component';
import LeftSubTwo from './../components/left-sub-two.component';
import { withRouter } from 'react-router-dom';
import { connect } from "react-redux";
import { goToLeftDefault, goToLeftOne, goToLeftTwo } from "./../actions/leftRouteActions.js";

class LeftComponent extends Component {
  render() {
    return (
      <div className="col-xs-6">
          <p>
            Current sub route: {this.props.currentRoute}
          </p>
          <ul>
            <li onClick={this.props.goToDefault}><Link to={'/'}>Go To Default</Link></li>
            <li onClick={this.props.goToSub1}><Link to={'/left-sub1'}>Go To One</Link></li>
            <li onClick={this.props.goToSub2}><Link to={'/left-sub2'}>Go To Two</Link></li>
          </ul>
          <Switch>
            <Route exact path='/' component={LeftSubDefault} />
            <Route exact path='/left-sub1' component={LeftSubOne} />
            <Route exact path='/left-sub2' component={LeftSubTwo} />
          </Switch>
      </div>
    );
  }
}
const mapStateToProps = (store) => {
  return {
    currentRoute: store.routes.currentRoute
  };
}
const mapDispatchToProps = (dispatch) => {
  return {
    goToDefault: () => {
      dispatch(goToLeftDefault())
    },
    goToSub1: () => {
      dispatch(goToLeftOne())
    },
    goToSub2: () => {
      dispatch(goToLeftTwo())
    }
  };
}
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(LeftComponent));

PS:我在控制台中没有错误.代码运行干净只是组件不加载.这是github上的类似线程:4671.我在各个站点上看到了很多线程,但没有解决此问题的方法.

Answer 1

哈,现在我正在用react-router和redux做一个项目=).

查看有关redux集成的官方文档https://reacttraining.com/react-router/web/guides/redux-integration.

我认为重点是withRouter和connectHocs的顺序.

问题是Redux实现了shouldComponentUpdate,如果它没有从路由器接收道具,则没有任何迹象表明有任何改变.这很容易解决.找到连接组件的位置并将其包装在withRouter中.

来自官方文档.

UPD

import { withRouter } from 'react-router-dom';
import { connect } from 'react-redux';

class Home extends React.Component {...}

export default withRouter(
    connect(mapStateToPropsFunc)(Home)
);
