React route v4中没有vue的beforeEach的功能，可以用以下两种思路，来做路由鉴权：

1. Route组件的render中鉴权

定义AuthRoute组件

import React from 'react'
import PropTypes from 'prop-types'
import { Route, Redirect } from 'react-router-dom'
const AuthRoute = ({ component: Component, authenticated, redirectTo, ...rest}) => {
  return (
    <Route
      {...rest}
      render={props => (
        authenticated ? (
          <Component {...props} />
        ) : (
          <Redirect to={{
            pathname: redirectTo,
            state: { from: props.location }  
          }}
          />
        )
      )}
    />
  )
}
AuthRoute.propTypes = {
  authenticated: PropTypes.bool,
  redirectTo: PropTypes.string.isRequired,
  component: PropTypes.func.isRequired,
}
AuthRoute.defaultProps = {
  authenticated: false,
}
export default AuthRoute

使用AuthRoute组件

import React, { Component } from 'react'
import { AuthRoute } from 'react-router-auth'
import UserProfile from './UserProfile'
class Example extends Component {
  render () {
    return (
      <AuthRoute path="/profile" component={UserProfile} redirectTo="/login" authenticated={this.props.authenticated} />
    )
  }
}

2. history的listen方法中鉴权

// 加入对history的监听
this.props.history.listen((location, action) => {
  // 执行内容, 第一个参数是当前的location, 第二个是此次执行的动作
  console.log(action, location.pathname, location.state)
})

要使用React router提供的history对象，可以从props中取到，不要使用自己定义的history对象，否则，监听Link跳转无效
