首先使用router

import React, { Component } from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import { Provider } from 'mobx-react';
import stores from '../store/index';
import Bundle from '../components/bundle';
import Hello from 'bundle-loader?lazy!../components/hello.jsx';
 
// 这是按需加载，对于现在讨论的问题没有影响
const HelloAPP = () => (
    <Bundle load={Hello}>
        {(Hello) => <Hello />}
    </Bundle>
);
export default class App extends Component {
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <Provider { ...stores }>
        <BrowserRouter basename="/">
          <Route path="/" component={HelloAPP}/>
        </BrowserRouter>
      </Provider>
    );
  };
}

　　接着是子组件的使用history

import React, { Component } from 'react';
// 需要这步，你要npm 这个，
import PropTypes from 'prop-types';
export default class Hello extends Component {
  constructor(props) {
    super(props);
  }
  // 这一步是重点
  static contextTypes = {
    router: PropTypes.object.isRequired
  };
  test = () => {
    console.log(this.context);
    setTimeout(() => {
      this.context.router.history.push("/otherPath");
    }, 1000);
  };
  render() {
    return (
      <div>
        <button onClick={this.test}>按钮</button>
      </div>
    );
  };
}

　　让我们看看this.context :
