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: 1, name: 'Tom'}, {id: 2, name: 'Jerry'}, {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} </li> )} </ul> </div> );} |

// config/config.jsexport default{ plugins: [ "umi-plugin-react", { antd: true, // true为启用 dva: true } ]} |
