我正在开发一个单页 ReactJS Web 应用程序，但我知道我在定义路由时做错了什么React Router V4.
我的问题如下：PrivateRoute in my routes.js文件未按预期工作。也就是说，我不知道为什么，但我的侧边栏菜单是我的主菜单的子组件App，无法正常工作：当我单击我的菜单项时，出现一些错误PrivateRoute组件（在本例中，Page1）。当我说错误时，我的意思是当我单击某个项目的菜单项时PrivateRoute，侧边栏菜单配置错误。成分含量（Page1）已呈现，但侧边栏菜单中的菜单项并未按应有的方式保持突出显示：在本例中，它被重定向到列表中的第一个菜单项MainHome.
尽管如此，如果我更改我的标签Page1组件来自PrivateRoute to ConfigRoute in my routes.js文件，一切正常。
我的文件中的示例index.js（主要的），routes.js, App.js, and side-menu.js:
index.js（主要）文件：
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import Routes from './routes';
import store from './store';
ReactDOM.render(
<Provider store={store}>
<Routes/>
</Provider>,
document.getElementById('root')
);
routes.js file:
import React, { Fragment } from 'react';
import { BrowserRouter, Switch, Route, Redirect } from 'react-router-dom';
import { connect } from 'react-redux';
import Login from './login';
import App from './App';
import MainHome from './home';
import Page1 from './page1';
const ConfigRoute = ({ component: Component, layout: Layout, ...rest }) => (
<Route {...rest} render={(props) => (
<Layout>
<Component {...props}/>
</Layout>
)}/>
);
const PrivateRoute = ({ component: Component, layout: Layout, auth_status, ...rest }) => (
<Route {...rest} render={(props) => (
<Fragment>
{auth_status === true
? (
<Layout>
<Component {...props}/>
</Layout>
)
: (
<Redirect to={{ pathname: "/", state: { from: props.location } }}/>
)
}
</Fragment>
)}/>
);
const Routes = (props) => (
<Router>
<Switch>
<Route exact path="/" component={Login}/>
<ConfigRoute path="/home" layout={App} component={MainHome}/>
<PrivateRoute path="/page1" auth_status={props.auth_status} layout={App} component={Page1}/>
</Switch>
</Router>
);
const mapStatetoProps = state => ({
auth_status: state.auth.isAuthenticated,
});
export default connect(mapStatetoProps)(Routes);
App.js file
import React, { Component } from 'react';
import { Layout } from 'antd';
import SideMenu from './side-menu';
import MainHeader from './main-header';
import MainFooter from './main-footer';
const { Content } = Layout;
class App extends Component {
constructor(props) {
super(props);
this.state = {
collapsed: false,
};
}
toggle = () => {
this.setState({
collapsed: !this.state.collapsed,
});
}
render() {
return (
<Layout style={{ minHeight: '100vh' }}>
<SideMenu collapsed={this.state.collapsed}/>
<Layout>
<MainHeader triggerParentUpdate={this.toggle} collapsed={this.state.collapsed}/>
<Content style={{ margin: '24px 16px', padding: 24, background: '#ffffff', minHeight: 280 }}>
{this.props.children}
</Content>
<MainFooter/>
</Layout>
</Layout>
);
}
}
export default App;
side-menu.js file:
import React from 'react';
import { Layout, Menu, Icon } from 'antd';
import { NavLink } from 'react-router-dom';
const { Sider } = Layout;
const SubMenu = Menu.SubMenu;
class SideMenu extends React.Component {
render() {
return (
<Sider
trigger={null}
collapsible
collapsed={this.props.collapsed}
>
<div className="logo"/>
<Menu theme="dark" mode="inline" defaultSelectedKeys={['1']}>
<Menu.Item key="1">
<NavLink to="/home">
<Icon type="home"/>
<span>home</span>
</NavLink>
</Menu.Item>
<Menu.Item key="2">
<NavLink to="/page1">
<Icon type="star-o"/>
<span>page 1</span>
</NavLink>
</Menu.Item>
</Menu>
</Sider>
);
}
}
export default SideMenu;
