为什么不能在react-router中嵌套Route组件4.x?
Why can I not nest Route components in react-router 4.x?
如何在 react-router 中使用嵌套路由,特别是版本 4.x?以下在以前的版本中运行良好...
<Route path='/stuff' component={Stuff}>
<Route path='/stuff/a' component={StuffA} />
</Route>
升级到 4.x 会引发以下警告...
Warning: You should not use <Route> component and <Route children> in the same route; <Route children> will be ignored
这到底是怎么回事?我已经搜索了 the docs 几个小时,但无法成功使嵌套路由正常工作。如何使用 <Route>
components 将他们的路由嵌套在 react-router v4 中?我的简单示例如何转换为 v4.x API 嵌套路由的合规性?
忘记你对 React Router < v4 的了解。您通过逐字嵌套 <Routes>
来嵌套路由。检查 this example。具体检查主题组件。您无需预先声明路由,而是在组件呈现时动态声明。
import React from 'react'
import {
BrowserRouter as Router,
Route,
Link
} from 'react-router-dom'
const BasicExample = () => (
<Router>
<div>
<ul>
<li><Link to="/">Home</Link></li>
<li><Link to="/about">About</Link></li>
<li><Link to="/topics">Topics</Link></li>
</ul>
<hr/>
<Route exact path="/" component={Home}/>
<Route path="/about" component={About}/>
<Route path="/topics" component={Topics}/>
</div>
</Router>
)
const Home = () => (
<div>
<h2>Home</h2>
</div>
)
const About = () => (
<div>
<h2>About</h2>
</div>
)
const Topics = ({ match }) => (
<div>
<h2>Topics</h2>
<ul>
<li>
<Link to={`${match.url}/rendering`}>
Rendering with React
</Link>
</li>
<li>
<Link to={`${match.url}/components`}>
Components
</Link>
</li>
<li>
<Link to={`${match.url}/props-v-state`}>
Props v. State
</Link>
</li>
</ul>
{/* NESTED ROUTES */}
<Route path={`${match.url}/:topicId`} component={Topic}/>
<Route exact path={match.url} render={() => (
<h3>Please select a topic.</h3>
)}/>
</div>
)
const Topic = ({ match }) => (
<div>
<h3>{match.params.topicId}</h3>
</div>
)
export default BasicExample
使用 react-router v4 和 v5 你也可以使用 render
属性来嵌套路由
<Route
path='/stuff'
render={({ match: { url } }) => (
<>
<Route path={`${url}/`} component={Stuff} exact />
<Route path={`${url}/a`} component={StuffA} />
</>
)}
/>
在我看来,与将子路由拆分为通过 component
prop 传入的单独定义的组件相比,这种语法在大多数情况下最终更具可读性。
我发布了一个 但注意到这个问题也有很多观点,所以认为将它移植到这里会有所帮助。
