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;

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

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

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

  return null;
}

用钩子:

import { useEffect } from 'react'
import { withRouter } from 'react-router-dom'
import { history as historyShape } from 'react-router-prop-types'

const DebugHistory = ({ history }) => {
  useEffect(() => {
    console.log('> Router', history.action, history.location)
  }, [history.location.key])

  return null
}

DebugHistory.propTypes = { history: historyShape }

export default withRouter(DebugHistory)

导入并呈现为<DebugHistory>组件

在某些情况下，你可能会使用render attribute而不是component，如下所示:

class App extends React.Component {

    constructor (props) {
        super(props);
    }

    onRouteChange (pageId) {
        console.log(pageId);
    }

    render () {
        return  <Switch>
                    <Route path="/" exact render={(props) => { 
                        this.onRouteChange('home');
                        return <HomePage {...props} />;
                    }} />
                    <Route path="/checkout" exact render={(props) => { 
                        this.onRouteChange('checkout');
                        return <CheckoutPage {...props} />;
                    }} />
                </Switch>
    }
}

注意，如果你在onRouteChange方法中改变状态，这可能会导致“最大更新深度超出”错误。

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]);
}

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}`)
})
