无法将 history 道具传递给组件

Question

我想将 history 属性从 App 向下传递给导航组件。当我尝试这样做时，我收到以下错误消息：

失败的道具类型：道具history在Navigation中被标记为必需，但其值为undefined。

我该如何解决这个问题？

App.js:

import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';

const App = props => (
  <Router>
      <MainLayout {...props}>
        <Switch>
          <Route exact name="index" path="/" component={Index}/>
          <Route component={NotFound}/>
        </Switch>
      </MainLayout>
  </Router>
);

MainLayout.js:

import React from "react";
import PropTypes from "prop-types";
import Navigation from "../../components/Navigation/Navigation";

const MainLayout = props => {
  const { children, authenticated, history } = props;

  return (
    <div>
      <Navigation authenticated={authenticated} history={history} />
      {children}
    </div>
  );
};

MainLayout.PropTypes = {
  children: PropTypes.node.isRequired,
  authenticated: PropTypes.bool.isRequired,
  history: PropTypes.object.isRequired,
};

export default MainLayout;

解决方案 #1：

如果您只是将 <MainLayout /> 转换为呈现的 <Route />，您将可以访问历史对象。

<Route render={(props) => 
  <MainLayout {...props}>
    <Switch>
      <Route exact name="index" path="/" component={Index}/>
      <Route component={NotFound}/>
    </Switch>
  </MainLayout>
}/>

<App /> 无法访问历史作为道具，所以这永远不会做你想做的事 <MainLayout {...props}>

解决方案 #2

您还可以在您的应用程序中将历史对象作为单个导出模块引用，并在您的应用程序中引用 React 路由器和任何其他组件/javascript 文件。

import { Router, Switch, Route } from 'react-router-dom';
import history from './history';

const App = props => (
  <Router history={history}>
      <MainLayout history={history} {...props}>
        <Switch>
          <Route exact name="index" path="/" component={Index}/>
          <Route component={NotFound}/>
        </Switch>
      </MainLayout>
  </Router>
);

(history.js)

import createBrowserHistory from 'history/createBrowserHistory';

export default createBrowserHistory();

对于 react-router-dom v4

为了获得 Router 组件的属性，我使用了 withRouter，我想下面的更改应该有效，

export default wihtRouter(MainLayout);

这应该可以在 MainLayout

中使用 props.history
