umi g page index// 创建index首页，会创建一个pages文件夹，里面有index.js 和index.cssumi dev// 启动项目到8000端口，localhost:8000会显示刚刚创建的indexumi g page about// 创建about页面， pages文件夹里面增加about.js 和 about.css,即可访问localhost:8000/about |

pages文件夹里面创建users文件夹，users文件夹里面创建$id.js和$id.css// $id.jsimport styles from \'./$id.css\';
export default function(props) {
return (
<div className={styles.normal}>
<h1>Page {props.match.params.id} test</h1>
</div>
);
}// url输入localhost:8000/users/1 显示 page 1 test// url输入localhost:8000/users/2 显示 page 2 testumi g page users/_layout// 在users文件夹里面增加_layout.js 和 _layout.css// url输入localhost:8000/users/1 显示 page layout// url输入localhost:8000/users/2 显示 page layout// 修改layout.js代码import styles from \'./_layout.css\';
export default function(props) {
return (
<div className={styles.normal}>
<h1>Page _layout</h1>
{props.children} // 显示子路由内容
</div>
);
}// url输入localhost:8000/users/1 显示 page layout 和page 1 test// url输入localhost:8000/users/1 显示 page layout 和page 2 test |

umi g page users/index// users/index 代码import Link from \'umi/link\'
// umi 对props.history进行了封装import router from \'umi/router\'
import styles from \'./index.css\';
const users = [

{id: 3, name: \'Bob\'}
]export default function(props) {
return (
<div className={styles.normal}>
<h1>Page User List</h1>
<ul>
{users.map(user =>
// 通过点击事件的方式跳转
<li key={user.id} onClick={() =>
// 也可使用router.push(`/users/${user.id}`)
props.history.push(`/users/${user.id}`)}>
{/* <Link to={`/users/${user.id}`}>{user.name}</Link> */} // 通过标签方式跳转
{user.name}

export default{
routes: [

{path: "/about", component: "./about", Routes: [
"./routes/PrivateRoute.js" // 是相对于根目录的
]}, // Routes 路由守卫
{
path: "/users",
component: "./users/_layout"

// goods.jsimport axios from \'axios\'
function getGoods(){ return axios.get(\'/Api/goods\')

},
reducers: {
initGoods(state, action){
return action.payload
},
// 更新状态

}),
{
addGood: title => ({
type: \'goods/addGood\', // 命名空间+reducer组成名字

// config/config.jsexport default{
plugins: [
"umi-plugin-react",
{
antd: true, // true为启用
dva: true
}
]
} |
8. 拦截器在全局下的应用——global.js
9. src/app.js——修改dva的配置
