Question

我有2条路线，/和/about，我已经测试了几条路线。所有路由仅呈现/的主组件。

当我尝试不存在的路线时，它会识别出正常并显示警告 Warning: No route matches path "/example". Make sure you have <Route path="/example"> somewhere in your routes

App.js

import React from 'react';
import Router from 'react-router';
import { DefaultRoute, Link, Route, RouteHandler } from 'react-router';
import {Home, About} from './components/Main';

let routes = (
    <Route name="home" path="/" handler={Home} >
        <Route name="about" handler={About} />
    </Route>
);

Router.run(routes, function (Handler) {  
  React.render(<Handler/>, document.body);
});

./组件/主

import React from 'react';

var Home = React.createClass({
    render() {
        return <div> this is the main component </div>
    }
});

var About = React.createClass({
    render(){
        return <div>This is the about</div>
    }
});

export default {
    Home,About
};

我尝试添加一条明确的路径，但无济于事。 <Route name="about" path="/about" handler={About} />

我偶然发现了stackoverflow Q，但在答案中找不到任何救赎。

任何人都可以了解可能出现的问题吗？

使用ES6和最新的react-router看起来像这样：

import React from 'react';
import {
  Router,
  Route,
  IndexRoute,
}
from 'react-router';

const routes = (
  <Router>
    <Route component={Home} path="/">
      <IndexRoute component={About}/>
    </Route>
  </Router>
);

const Home = React.createClass({
  render() {
    return (
      <div> this is the main component
        {this.props.children}
      </div>
    );
  }
});

//Remember to have your about component either imported or
//defined somewhere

React.render(routes, document.body);

在旁注中，如果要将不合适的路线与特定视图匹配，请使用：

<Route component={NotFound} path="*"></Route>

注意路径设置为*

还要编写自己的NotFound组件。

我的样子如下：

const NotFound = React.createClass({
  render(){
   let _location = window.location.href;
    return(
      <div className="notfound-card">
        <div className="content">
          <a className="header">404 Invalid URL</a >
        </div>
        <hr></hr>
        <div className="description">
          <p>
              You have reached:
          </p>
          <p className="location">
            {_location}
          </p>
        </div>
      </div>
    );
  }
});

Answer 2

由于您已在About下嵌套Home，因此您需要在<RouteHandler />组件中呈现Home组件，以便React Router能够显示你的路线组件。

import {RouteHandler} from 'react-router';

var Home = React.createClass({
    render() {
        return (<div> this is the main component
            <RouteHandler />
        </div>);
    }
});

React Router仅识别索引路由
