入口文件entry.js   建立store

import React from 'react';
import ReactDOM from 'react-dom';
import { createStore, applyMiddleware } from 'redux';
import { Provider } from 'react-redux';
import { composeWithDevTools } from 'redux-devtools-extension';
import thunk from 'redux-thunk';
import { ConnectedRouter, routerReducer, routerMiddleware, push } from 'react-router-redux';
import { AppContainer } from 'react-hot-loader';
import App from './App';
import createHistory from 'history/createBrowserHistory';
import rootReducer from './reducers/index';
const history = createHistory();
const middleware = routerMiddleware(history)
const middlewares = [thunk, middleware];
const store = createStore(rootReducer, composeWithDevTools(applyMiddleware(...middlewares)));

const render = Component =>
    ReactDOM.render(
        <AppContainer>
            <Provider store={store}>
                <Component />
            </Provider>
        </AppContainer>,
        document.getElementById('root')
    );
render(App)

//模块热更新
if(module.hot) {
    module.hot.accept('./App', () => { render(App) });
}

路由App.js

import React from 'react'
import { connect } from 'react-redux'
import { bindActionCreators } from 'redux';
import { Route, HashRouter as Router } from 'react-router-dom'
import createHistory from 'history/createHashHistory'
const history = createHistory()
import HomeContainer from './containers/home/homeContainers'
import Login from './containers/login/Login'
import Register from './containers/register/register'

export default class App extends React.Component {
  render() {
      return (
          <Router history={history}>
              <Route render={({ location }) => {
                  return(
                          <div key={location.pathname}>
                              <Route location={location} exact path="/" component={HomeContainer} />
                              <Route location={location} path="/login" component={Login} />
                              <Route location={location} path="/register" component={Register} />
                          </div>
                  )
              }}/>
          </Router>
    );
  }
}

路由组件主页F:homeContainers.js

import React  from 'react';
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import PropTypes from 'prop-types';
import Header from 'components/homeComponents/header';
import Hot from 'components/hot/hot';

export default class HomeContainer extends React.Component {

    constructor(props) {
        super(props);
        //构造函数用法
        //经常使用来绑定自定义函数，不要在这里或者组件的任何位置setState，state所有在reducer初始化
    }

    render() {
      alert(this.props.location);
        return(
            <div key={this.props.location}>
                <Header   linkTo="login"  linkToRegister="register"
                />
            </div>
          )
    }
}

路由组件Login.js 

import React from 'react';
 import { bindActionCreators } from 'redux';
 import { connect } from 'react-redux';
 import PropTypes from 'prop-types';
 import * as login from 'actions/login';
import isEmpty from 'lodash/isEmpty';
/ * dispatch用法：（单个action）bindActionCreators(navActions, dispatch)，（多个action）bindActionCreators({...action1, ...action2}, dispatch)
 */
 @connect (
     state => state,
     dispatch => bindActionCreators(login, dispatch)
 )

export default class Login extends React.Component {
constructor(props) {
    super(props);

    this.Click = (event) => {
      event.preventDefault();
        let user = this.refs.user.value;
        let psw = this.refs.psw.value;
        if (isEmpty(user)) {

          alert('用户名为空');
        }
        if (isEmpty(psw)) {
          alert('密码不能为空');
        }
        this.props.login_success(user ,psw);
    }

}
render() {

     const {last_time} = this.props.login;

    return(
        <div>
          <form>
              <div>
              <span>用户名:</span>
              <input type='text' name='user' ref='user' placeholder='请输入用户名'/>
              </div>
              <div>
              <span>密码:</span>
              <input type='text' name='psw' placeholder='请输入密码' ref='psw'/>
              </div>
               <input  type='submit'  value='登录' onClick={this.Click} />

              <div>
              {last_time}
              </div>
          </form>

        </div>
      )
    }
}

主页中的组件header.js

import React ,{Component} from 'react';
import { Link } from 'react-router-dom';
class  Header  extends React.Component {
  render() {
      const {  linkToRegister,  linkTo  } = this.props  //传参数
      return (
          <div >
              <Link to={linkTo} className="login" >登录
              </Link>

              <Link to={linkToRegister} className="register" >注册
              </Link>
          </div>
      )
  }
}

export  default  Header;

点击Link标签登录就会更加to的url跳转，Login组件，输入提交触发action

actions----------login.js

import fetch from 'isomorphic-fetch'

import queryString from 'queryString'

export const success = (data) => ({
    type: 'login_success',
    data
})

/

// 页面初次渲染时获取数据
export const login_success = (user , psw) => {

    return dispatch => {
          fetch('http://localhost:9090/zl.zy/zy/login.do', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8',
            },
            body: queryString.stringify({ 'user': user ,'psw' :psw })

       //用queryString转化，以前用JSON转化不行
        })
        .then((response) => {
          debugger
               if(response.ok){
                  return  response.json();
                }
        })
        .then(data=>
        dispatch(success(data)))
    }
}

// 页面初次渲染时获取数据
export const login_success = (user , psw) => {

    return dispatch => {
          fetch('http://localhost:9090/zl.zy/zy/login.do', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8',
            },
            body: queryString.stringify({ 'user': user ,'psw' :psw })

       //用queryString转化，以前用JSON转化不行
        })
        .then((response) => {
          debugger
               if(response.ok){
                  return  response.json();
                }
        })
        .then(data=>
        dispatch(success(data)))
    }
}

测试的时候后台没有搭建的话能够用  login.js,当提交成功的时候改变last_time

import fetch from 'isomorphic-fetch'

export const login_success= () => ({
    type: 'success',
    last_time:1
})

reducer：  login.js
const initState = {
last_time:'2'
}

export const login = (state = initState, action) => {
    switch (action.type) {
        case "login_success":
            return {
                ...state,
                last_time: action.last_time,
            }
        default:
            return state
    }
}

注册reducer：index.js

import { combineReducers } from 'redux';
import { routerReducer } from 'react-router-redux'

import { login } from './login';
//注册reducer，每一个自定义的reducer都要来这里注册！！！不注册会报错。
const rootReducer = combineReducers({
  routing: routerReducer,
  login
});

export default rootReducer;

最后将login.js中注册提交  last_time=1说明搭建成功
