Usign react-router-dom，如何从React组件外部访问browserHistory对象？

Question

使用以前的react-router，我可以做到这一点：

import {browserHistory} from 'react-router';

从我的actionCreators文件中，我可以执行以下操作：

...some async action completed (for example, user logged in successfully)..
browserHistory.push('/dashboard');

但是随着新的react-router-dom（v4）的出现，我似乎无法再像那样导入browserHistory，并且访问历史对象的唯一方法是从React组件props

this.props.history

使用react-router-dom完成异步redux操作后，如何将用户重定向到新页面？

您正在寻找withRouter。

“您可以通过withRouter高阶组件访问历史对象的属性和最接近的匹配项。”

import React, { PropTypes } from 'react'
import { withRouter } from 'react-router'

// A simple component that shows the pathname of the current location
class ShowTheLocation extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>You are now at {location.pathname}</div>
    )
  }
}

// Create a new component that is "connected" (to borrow redux
// terminology) to the router.
const ShowTheLocationWithRouter = withRouter(ShowTheLocation)
