javascript-通过React-router渲染子组件

所以我一直在努力与这段代码.我有一个接受儿童作为道具的组件,它应该是我托管的所有页面的基础.

Base.jsx：

import React from 'react';
import PropTypes from 'prop-types';
import { Link, NavLink } from 'react-router-dom';

const Base = ({ child }) => (
    <div>
        <div className="top-bar">
            <div className="top-bar-left">
                <NavLink to="/">React App</NavLink>
            </div>

            <div className="top-bar-right">
                <Link to="/login">Log in</Link>
            </div>

        </div>

        {child.render()} // HERE IS THE CHILD TO RENDER

    </div>
);

Base.propTypes = {
    child: PropTypes.object.isRequired
};
export default Base;

然后,在app.jsx中,ReactDom.render()所在的位置是：

import React from 'react';
import ReactDom from 'react-dom';
import injectTapEventPlugin from 'react-tap-event-plugin';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import {BrowserRouter, Switch, Route} from 'react-router-dom';
import LoginPag from './components/LoginPag.jsx';
import Base from './components/Base.jsx';
import HomePage from './components/HomePage.jsx';

// for MaterialUI to work properly
injectTapEventPlugin();

const TestLogin = (props) => {
    return (<Base child={LoginPag} />);
};

const TestBase = (props) => {
    return(<Base child={HomePage}/>)
};

ReactDom.render((<BrowserRouter><MuiThemeProvider muiTheme={getMuiTheme()}>
    <div>
    <Switch>
        <Route exact path="/" component={TestBase} />
        <Route exact path="/login" component={TestLogin}/>
    </Switch>
    </div>
    </MuiThemeProvider>
</BrowserRouter>), document.getElementById('react-app'));

最后,HomePage和LoginPag相似,这是HomePage.jsx：

import React from 'react';
import { Card, CardTitle } from 'material-ui/Card';

const HomePage = {
    render() {
        return (<Card className="container">
            <CardTitle title="React Application" subtitle="This is the home page." />
        </Card>);
    }
};

export default HomePage;

我现在的问题是：是否有可能摆脱这些抽象TestLogin和TestBase？

我的最终目标是拥有这样的东西：

<路由精确路径=“ /” component = {Base(HomePage)} />就是说,摆脱抽象层并直接在一行中进行渲染.

提前致谢.

编辑：由于有甲龙,我可以实现我想要的.我也可以上课吗？该类被声明为LoginPage类扩展了React.Component并具有render()方法.

解决方法:

您可以使用render内联显示组件,

<Route exact path="/" render={()=><Base child={HomePage} />} />
<Route exact path="/login" render={()=><Base child={LoginPage} />}/>
