1. 安装 dva-cli # 

$ mkdir  zhufeng-umi-dva4
$ cd zhufeng-umi-dva4
$ yarn create umi

2. 创建新应用 # 

$ dva new zhufeng-umi-dva
$ cd zhufeng-umi-dva
$ npm start

在浏览器里打开 http://localhost:8000 ，你会看到 dva 的欢迎界面。

3. 使用 antd # 

cnpm i antd -S
cnpm i babel-plugin-import -D

{
  "extraBabelPlugins": [
    ["import", { "libraryName": "antd", "libraryDirectory": "es", "style": "css" }]
  ]
}

4. 首页导航 #

4.1 router.js #

src/router.js

+        <Route path="/" component={IndexPage} />

4.2 src/routes/IndexPage.less #

src/routes/IndexPage.less

4.3 routes\IndexPage.js #

src\routes\IndexPage.js

import React from 'react';
import { connect } from 'dva';
import styles from './IndexPage.less';
import {Layout} from 'antd';
import NavBar from '../components/NavBar';
const {Content} = Layout;
function IndexPage(props) {
  return (
    <Layout>
      <NavBar {...props}/>
      <Content>内容</Content>
    </Layout>
  );
}
export default connect()(IndexPage);

4.4 components\NavBar\index.js #

src\components\NavBar\index.js

import {Menu} from 'antd';
import styles from './index.less';
import {Link} from 'dva/router';
import React, { Component } from 'react';
import {Layout} from 'antd';
let logo = require('../../assets/logo.png');
export default class NavBar extends Component {
  render() {
    return (
      <Layout.Header className={styles.header}>
        <img src={logo}/>
        <Menu  className={styles.menu} mode="horizontal" selectedKeys={[this.props.location.pathname]} >
            <Menu.Item key="/home"><Link to="/home">主页</Link></Menu.Item>
            <Menu.Item key="/user"><Link to="/user">用户管理</Link></Menu.Item>
            <Menu.Item key="/profile"><Link to="/profile">个人中心</Link></Menu.Item>
            <Menu.Item key="/login"><Link to="/login">登录</Link></Menu.Item>
            <Menu.Item key="/register"><Link to="/register">注册</Link></Menu.Item>
        </Menu>
      </Layout.Header> 
    )
  }
}

4.5 components\NavBar\index.less #

src\components\NavBar\index.less

.header{
    height:48px;
    line-height: 48px;
    background-color: #FFF;
    img{
        height:48px;
    }
    .menu{
        display:inline-block;
        height:48px;
    }

}

5. 实现路由 #

5.1 routes/IndexPage.js #

src/routes/IndexPage.js

import React from 'react';
import { connect } from 'dva';
import styles from './IndexPage.less';
import {Layout} from 'antd';
import NavBar from '../components/NavBar';
import {Route,Switch,Redirect} from 'dva/router';
import Home from './Home';
import User from './User';
import Profile from './Profile';
import Register from './Register';
import Login from './Login';
const {Content} = Layout;
function IndexPage(props) {
  return (
    <Layout>
      <NavBar {...props}/>
      <Content>
        <Switch>
          <Route path="/home" component={Home} />
          <Route path="/user" component={User} />
          <Route path="/profile" component={Profile} />
          <Route path="/register" component={Register} />
          <Route path="/login" component={Login} />
          <Redirect  to="/home"/>
        </Switch>
      </Content>
    </Layout>
  );
}
export default connect()(IndexPage);

6. 配置式路由 #

6.1 src/router.js #

src/router.js

import React from 'react';
import { Router, Switch } from 'dva/router';
import {renderRoutes} from './utils/routes';
import routesConfig from './routeConfig';
function RouterConfig({ history }) {
  return (
    <Router history={history}>
      <Switch>
        {renderRoutes(routesConfig)}
      </Switch>
    </Router>
  );
}

export default RouterConfig;

6.2 routes/IndexPage.js #

src/routes/IndexPage.js

import React from 'react';
import { connect } from 'dva';
import {Layout} from 'antd';
import NavBar from '../components/NavBar';
import {Switch} from 'dva/router';
import NoMatch from '../components/NoMatch';
import {renderRoutes,renderRedirect} from '../utils/routes';
const {Content} = Layout;
function IndexPage(props) {
  return (
    <Layout>
      <NavBar {...props}/>
      <Content>
        <Switch>
          {renderRoutes(props.routes)}
          {renderRedirect('/',true,props.routes)}
          <NoMatch/>
        </Switch>
      </Content>
    </Layout>
  );
}

export default connect()(IndexPage);

6.3 utils/routes.js #

src/utils/routes.js

import {Route,Redirect} from 'dva/router';
export function renderRoutes(routesConfig){
    return routesConfig.map(({path,exact=false,component:Component,routes=[]},index)=>(
        <Route path={path} exact={exact} key={index} render={props=><Component {...props} routes={routes}/>}/>
    ))
}
export function renderRedirect(from,exact,routesConfig){
    let {path} = routesConfig.find(route=>route.redirect)||routesConfig[0];
    return <Redirect exact={exact} from={from} to={path}/>
}

6.4 routeConfig.js #

src/routeConfig.js

import IndexPage from './routes/IndexPage';
import Home from './routes/Home';
import User from './routes/User';
import Profile from './routes/Profile';
import Register from './routes/Register';
import Login from './routes/Login';
export default  [
  {
    path:'/',
    component:IndexPage,
    routes:[
      {
        path:'/home',
        component:Home
      },
      {
        path:'/user',
        component:User
      },
      {
        path:'/profile',
        component:Profile
      },
      {
        path:'/login',
        component:Login
      }, {
        path:'/register',
        component:Register
      }
    ]
  }
]

6.5 components\NoMatch\index.js #

src\components\NoMatch\index.js

import React from 'react'

export default () => {
  return (
    <div>
      此页面不存在
    </div>
  )
}

7. 按需加载 #
