Question

我使用react-router v4进行路由，解析查询参数，建议使用history.listen here

我在生命周期钩子componentDidMount中调用它来确保组件已经安装，以便我可以使用像这样的高阶组件将它作为一个组件状态提供：

import createHistory from 'history/createBrowserHistory';
import qs from 'qs';
import { compose, lifecycle, withState } from 'recompose';

export const history = createHistory();
const withQs = compose(
  withState('search', 'setSearch', {}),
  lifecycle({
    componentDidMount: function () {
      // works on the client side
      history.listen(() => {
        // history.location = Object.assign(history.location,
          // parse the search string using your package of choice
        // { query: parseQueryString(history.location.search) }
        // )
        console.log('History Location', history.location);
        console.log('Search', history.location.search);
      })
    }
  })
)

export default withQs

当路线导航到新页面或新的查询参数添加到页面时，永远不会触发history.listen。

根据React Router V4 docs，如果您想自己管理历史记录，则需要使用<Router>代替<BrowserRouter>：

import { Router } from 'react-router'
import createBrowserHistory from 'history/createBrowserHistory'

const history = createBrowserHistory()

<Router history={history}>
  <App/>
</Router>

history.listen未在componentDidMount中触发
