Question

React Router v4渲染组件出现问题。在初始加载应用程序时，它将呈现与URL对应的正确组件但是，任何后续Link次点击都不会呈现所需的组件。

库

React Router: 4.2.2
React：15.6.1
React DOM：15.6.1
- 只是提到图书馆以防影响 -
- React Redux：5.0.6
- Redux：3.7.2
- 材料用户界面：0.19.0

为了简洁起见，省略一些imports

网站结构

index.jsx
  |
  App.jsx
    |
    Auth.jsx
      |
      Layout.jsx
        <Routes />

index.jsx

import React from 'react';
import store from './store.js';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { BrowserRouter } from 'react-router-dom';

import createBrowserHistory from 'history/createBrowserHistory';
const history = createBrowserHistory();

import App from './containers/App.jsx';

ReactDOM.render(
  <Provider store={store}>
    <MuiThemeProvider muiTheme={muiTheme}>
      <BrowserRouter>
        <App />
      </BrowserRouter>
    </MuiThemeProvider>
  </Provider>,
  document.getElementById('root')
);

App.jsx

import React, { Component } from 'react';
import Auth from '../components/Auth.jsx';

class App extends Component {
  render() {
    return <Auth />;
  }
}

Auth.jsx

import React from 'react';
import { Route } from 'react-router-dom';
import Layout from './Layout.jsx';

export default function Auth(props) {
  //this Has a render function to render a Loader, Error Page, or the Layout
  return <Layout />;
}

Layout.jsx

这里涉及渲染整个应用程序的复杂性。我将留下其他布局组件注释掉，只有一些链接和一个Switch组件才能使项目更加模块化。

import React, { Component } from 'react';
import { Link, Switch, Route } from 'react-router-dom';

import Overview from './views/overview/Overview.jsx';
import Home from './views/home/Home.jsx';

export default class Layout extends Component {
  render() {
    return (
      <div className="layout">
        {/* <TopBar /> */}
        {/* <AppBar/> */}
        {/* <Drawer>
              <MainMenu/>
            </Drawer> */}

            <Link to="/">HOME</Link>
            <Link to="/overview">Overview</Link>
            <Switch>
                <Route path="/" exact component={Home} />
                <Route path="/overview" component={Overview} />
            </Switch>

        {/* <Routes /> */}
        {/* <Footer /> */}
      </div>
    );
  }
}

Routes.jsx

这就是我想要的路线组件。

import React from 'react';
import { Switch, Route } from 'react-router-dom';

import Home from './views/home/Home.jsx';
import Overview from './views/overview/Overview.jsx';
import Admin from './views/admin/Admin.jsx';
import NotFound from './NotFound.jsx';

export default function Routes(props) {
  return (
    <Switch>
      <Route path="/" exact component={Home} />
      <Route path="/overview" component={Overview} />
      <Route path="/admin" component={Admin} />
      <Route component={NotFound} />
    </Switch>
  );
}

是否有一些我缺少的东西让组件点击Link呈现？我没有收到任何控制台错误或任何告诉我有问题的事情。所以不确定组件是否未正确包装或可能导致问题的原因。

Answer 1

看起来正在发生的事情是Redux集成阻止了更新。

需要：

import {withRouter} from 'react-router-dom';

export default withRouter(connect(mapStateToProps, mapDispatchToProps)(App))'

您也可以在连接中使用pure: false。
