在V4.x上更新React Router V2.x后,所有路由都会转到主页面。
以下是V2.x上的路线:
import {Router, Route, hashHistory } from 'react-router'
const routes = <Route component={App}>
<Route path="/results" component={Results} />
<Route path="/" component={Voting} />
</Route>;
ReactDOM.render(
<Router history={hashHistory}>{routes}</Router>,
document.getElementById('app')
);
这些是V4.x上的路线:
index.jsx文件:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'
import App from './components/App';
import Voting from './components/Voting';
import Results from './components/Results';
const withAppLayout = Component => props => <App><Component {...props} /></App>
const routes = <Switch>
<Route exact path="/" component={withAppLayout(Voting)} />
<Route path="/results" component={withAppLayout(Results)} />
</Switch>;
ReactDOM.render(
<Router component={App}>
{routes}
</Router>,
document.getElementById('app')
);
App.jsx文件:
import React from 'react';
import {List} from 'immutable';
const pair = List.of('Trainspotting', '28 Days Later');
export default React.createClass({
render: function () {
console.log(this.props.children);
return React.cloneElement(this.props.children, {pair: pair});
}
});
Voting.jsx文件:
import React from 'react';
import PureRenderMixin from 'react-addons-pure-render-mixin';
import Winner from './Winner';
import Vote from './Vote';
export default React.createClass({
mixins: [PureRenderMixin],
render: function () {
return <div>
{this.props.winner ?
<Winner ref="winner" winner={this.props.winner} /> :
<Vote {...this.props} />
}
</div>;
}
});
Results.jsx文件:
import React from 'react';
import PureRenderMixin from 'react-addons-pure-render-mixin';
export default React.createClass({
mixins: [PureRenderMixin],
render: function () {
return <div>Hello from results!</div>
}
});
如何解决此错误?
答案 0 :(得分:1)
有一件事是使用:
<Route exact path="/" component={withAppLayout(Voting)} />
确切的将确保只有那个确切的路径匹配。但是如果你有其他人之后的路径=“/”,那么其他人应该首先匹配。这是你正在使用的真实代码吗?
编辑:查看下面的完整版本。
import {BrowserRouter, Route, Switch} from 'react-router-dom'
ReactDOM.render(
<BrowserRouter>
<Switch>
<Route exact path="/" component={Voting} />
<Route path="/results" component={Results} />
</Switch>
</BrowserRouter>,
document.getElementById('app')
);
然后,如果能够解决问题,您可以将Switch部分移动到App Component中。此外,如果要使用哈希历史记录,则需要使用基本上使用哈希历史记录初始化路由器的HashRouter。
