v5.1引入了有用的钩子useLocation

https://reacttraining.com/blog/react-router-v5-1/#uselocation

import { Switch, useLocation } from 'react-router-dom'

function usePageViews() {
  let location = useLocation()

  useEffect(
    () => {
      ga.send(['pageview', location.pathname])
    },
    [location]
  )
}

function App() {
  usePageViews()
  return <Switch>{/* your routes here */}</Switch>
}

对于React路由器v6和React钩子， 你需要使用useLocation而不是useHistory，因为它已被弃用

import { useLocation } from 'react-router-dom'
import { useEffect } from 'react'

export default function Component() {

const history = useLocation();

   useEffect(() => {
    console.log('> Router', history.pathname)      
}, [history.pathname]);
}

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);

对于功能组件，请尝试使用props.location中的useEffect。

import React, {useEffect} from 'react';

const SampleComponent = (props) => {

      useEffect(() => {
        console.log(props.location);
      }, [props.location]);

}

export default SampleComponent;

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;
}
