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。

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。

对于react Hooks，我使用useEffect

import React from 'react'
const history = useHistory()
const queryString = require('query-string')
const parsed = queryString.parse(location.search)
const [search, setSearch] = useState(parsed.search ? parsed.search : '')

useEffect(() => {
  const parsedSearch = parsed.search ? parsed.search : ''
  if (parsedSearch !== search) {
    // do some action! The route Changed!
  }
}, [location.search])

在这个例子中，当路由改变时，我向上滚动:

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

const ScrollToTop = () => {
  const location = useLocation()

  React.useEffect(() => {
    window.scrollTo(0, 0)
  }, [location.key])

  return null
}

export default ScrollToTop

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
