五、路由跳转，link和router

1、umi的用法
这三种用法，最后/list接受到到参数都在，this.props.location.query里面

第一种
import Link from 'umi/link';
 <Link to="/list?a=b">Go to list page</Link>

import router from 'umi/router';
// 带参数
第二种
router.push('/list?a=b');
第三种
router.push({
  pathname: '/list',
  query: {
    a: 'b',
  },
});

2、普通react用法

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

    this.props.history.push({
      pathname: '/flow-node/list',
      query: {
        text: this.state.value,
      },
    });
export default withRouter(GlobalSearch);

3、遇到都问题
1、React.createClass is not a function

var Home = React.createClass({
    render:function(){
        return (
            <div>123</div>
        )
    }
})
//变成
class Home extends React.Component{
    render=function(){
        return (
            <div>123</div>
        )
    }
}

2、You should not use <Route component> and <Route children> in the same route; <Route children> will be ignored
4.0以上会出问题

    <HashRouter>
    <Route path="/" component={App1}>
      <Route component={Home}/>
      <Route path="df" component={Home1}/>
      <Route path="lsy" component={Home2}/>
    </Route>
    </HashRouter>

<HashRouter>
    <App1>
      <Route exact path="/" component={Home}/>  //默认页
      <Route path="/df" component={Home1}/>
      <Route path="/lsy" component={Home2}/>
    </App1>
    </HashRouter>

umi的路由配置

pages文件夹下自动配置路由

$UserSet文件夹会动态配置
http://localhost:8000/User/1这个页面

也可以用config文件

routes: pageRoutes,
// router.config
  /**
   * 无layout的界面
   * */
export default [
  {
    path: '/',
    component: './',
  },
  /**
   * 有layout的界面
   * */
  {
    path: '/test',
    component: '../layouts/basicLayout.js',
    routes: [
      {
        path: '/test',
        redirect: '/test/list',
      },
      {
        path: '/test/list',
        component: './Test/List',
      },
      //  动态
      {
        path: '/test/:key',
        component: './Test/Dynamic/index',
      },
    ],
  },
