React Router（v3）重定向不重定向到新位置

Question

我有这样的路由器设置：

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

import App from './components/app';
import Home from './components/Home';
import AuthorPage from './components/authors/AuthorPage';
import About from './components/about/About';
import NotFound from './components/NotFound';

const routes = (
    <Route path="/" component={App} >
      <IndexRoute component={Home} />
      <Route path="about" component={About} />
      <Route path="authors" component={AuthorPage} />
      <Route path="*" component={NotFound} />
      <Redirect from="/about-us" to="/about" />
    </Route>
);

export default routes;

除了重定向之外的一切都正常。每当我尝试导航到 /about-us 时，我都会看到一个显示 Cannot GET /about-us.

的白页

在文档中似乎找不到任何关于此的内容。路线的 "from" 部分是否仍然必须存在才能正常工作，还是应该不管怎样都重定向我？

编辑：

我还应该提到我使用了 history 包，如 react-router 升级指南中所述：https://github.com/rackt/react-router/blob/master/upgrade-guides/v1.0.0.md

这是我的 main.js:

import React from 'react';
import ReactDOM from 'react-dom';
import Router from 'react-router';
import routes from './routes';
import createBrowserHistory from 'history/lib/createBrowserHistory'

// Using history to avoid default behavior of weird urls like `?_k=umhx1s`
// See:  https://github.com/rackt/react-router/blob/master/upgrade-guides/v1.0.0.md
let history = createBrowserHistory();
const root = document.getElementById('app');

ReactDOM.render(<Router history={history}>{routes}</Router>, root);

Answer 1

你好像打错了。在您的路线中，您 <Route path="about" component={About} /> 注意到您有 path="about"，并且您正在尝试导航至 /about-us。这与您的任何路线都不匹配。尝试导航至 /about 或将您的路线更改为 <Route path="about-us" component={About} />.

原来我的路线顺序错了。我的 "catch all" NotFound-route 需要放在我的重定向之后才能工作。

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

import App from './components/app';
import Home from './components/Home';
import AuthorPage from './components/authors/AuthorPage';
import About from './components/about/About';
import NotFound from './components/NotFound';

const routes = (
  <Route path="/" component={App} >
    <IndexRoute component={Home} />
    <Route path="about" component={About} />
    <Route path="authors" component={AuthorPage} />
    <Redirect from="about-us" to="about" /> // Switched order with below Route.
    <Route path="*" component={NotFound} />
  </Route>
);

export default routes;
