从反应路由器3.x移动到4.x. [英] Moving from react router 3.x to 4.x

问题描述

如何使用 https://cdnjs.cloudflare.com/ajax/libs/react-router/4.0.0-2/react-router.min.js 使用 https://cdnjs.cloudflare.com/ajax/libs/react-router/3.0.1/ReactRouter.min.js ？

使用3.x以下的示例。

Example using 3.x below.

HTML

<script src="https://unpkg.com/react@15.4.2/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom@15.4.2/dist/react-dom.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-router/3.0.1/ReactRouter.min.js"></script>

JS

let { Router, IndexRoute, Redirect, Route, Link, browserHistory } = ReactRouter;

history.replaceState(0,0,'/');

const Main = () =>
  <Router history={browserHistory}>

    <Route path='/' component={App}>
      <IndexRoute component={Home}/>
      <Route path='map' component={Map}/>
      <Route path='settings' component={Settings}/>
            <Redirect from='foo' to='/' />
      <Route path='*' component={NotFound}/>
    </Route>

  </Router>

const App = props => 
  <div>
    <Navigation>
      <Link to='/map'>Map</Link>
      <Link to='/settings'>Settings</Link>
      <Link to='/foo'>Foo</Link>
    </Navigation>

    {props.children}

  </div>

const Navigation = props => <nav {...props} />
const Home = () => <h1>Home</h1>
const Map = () => <h1>Map</h1>
const Settings = () => <h1>Settings</h1>
const NotFound = (props) => <h1>404 - Not Found</h1>

ReactDOM.render(<Main />, document.body);

如果我搬到任何CDN托管4 .x版本虽然不起作用（返回语句后无法访问的代码）。

If I move to any of the CDN hosted 4.x versions though it doesn't work (unreachable code after return statement).

推荐答案

我能用redux配置它通过更改一些内容：

I was able to configure it with redux by changing a few things:

首先， browserHistory 未在 react-router上定义了。获得它的一种方法是使用包历史。

First, browserHistory is not defined on react-router anymore. One way to get it back is to use the package history.

您需要安装（redux可选） ：

You will need to install (redux optional):

npm i -S history react-router react-router-redux

而不是尝试导入 browserHistory 使用：

import { createBrowserHistory } from 'history';

如果您想使用redux，请将其导入并将其添加到合并的Reducer：

If you want to use redux then import this and add it to your combined reducers:

import { routerReducer as routing } from 'react-router-redux';

combineReducers({
  home, about,
  routing, // new
});

接下来你创建历史对象

// redux
import { syncHistoryWithStore } from 'react-router-redux';
const history = syncHistoryWithStore(createBrowserHistory(), store);

// regular
const history = createBrowserHistory();

然后更改路由器以使用新的历史记录对象

Then change your router to use the new history object

<Router history={ history } children={ Routes } />

其他一切都应该相同。

如果有人遇到道具历史记录在路由器中标记为必需，但其值未定义。

这是因为 browserHistory 在react-router中不再可用，请参阅post to use history package。

It is because browserHistory is no longer available in react-router, see post to use history package instead.
