我使用withRouter来获取位置道具。当组件因为一个新的路由而更新时，我检查值是否发生了变化:

@withRouter
class App extends React.Component {

  static propTypes = {
    location: React.PropTypes.object.isRequired
  }

  // ...

  componentDidUpdate(prevProps) {
    if (this.props.location !== prevProps.location) {
      this.onRouteChanged();
    }
  }

  onRouteChanged() {
    console.log("ROUTE CHANGED");
  }

  // ...
  render(){
    return <Switch>
        <Route path="/" exact component={HomePage} />
        <Route path="/checkout" component={CheckoutPage} />
        <Route path="/success" component={SuccessPage} />
        // ...
        <Route component={NotFound} />
      </Switch>
  }
}

使用useEffect钩子，可以在不添加侦听器的情况下检测路由更改。

import React, { useEffect }           from 'react';
import { Switch, Route, withRouter }  from 'react-router-dom';
import Main                           from './Main';
import Blog                           from './Blog';


const App  = ({history}) => {

    useEffect( () => {

        // When route changes, history.location.pathname changes as well
        // And the code will execute after this line

    }, [history.location.pathname]);

    return (<Switch>
              <Route exact path = '/'     component = {Main}/>
              <Route exact path = '/blog' component = {Blog}/>
            </Switch>);

}

export default withRouter(App);

您应该使用history v4 lib。

这里的例子

history.listen((location, action) => {
  console.log(`The current URL is ${location.pathname}${location.search}${location.hash}`)
  console.log(`The last navigation action was ${action}`)
})

要在上面的基础上展开，您需要获取history对象。如果您正在使用BrowserRouter，您可以导入withRouter并使用高阶组件(HoC)包装您的组件，以便通过道具访问历史对象的属性和函数。

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

    const myComponent = ({ history }) => {

        history.listen((location, action) => {
            // location is an object like window.location
            console.log(action, location.pathname, location.state)
        });

        return <div>...</div>;
    };

    export default withRouter(myComponent);

唯一需要注意的是，使用throuter和大多数其他访问历史的方法似乎会污染道具，因为它们将对象解构到其中。

正如其他人所说，这已经被react路由器暴露的钩子所取代，并且它有内存泄漏。如果你在一个函数组件中注册监听器，你应该通过useEffect来做，然后在函数的返回中取消注册。

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

const Scroll = () => {
  const history = useHistory();

  useEffect(() => {
    window.scrollTo(0, 0);
  }, [history.location.pathname]);

  return null;
}

import React, { useEffect } from 'react';
import { useLocation } from 'react-router';

function MyApp() {

  const location = useLocation();

  useEffect(() => {
      console.log('route has been changed');
      ...your code
  },[location.pathname]);

}

用钩子
