使用 react-router-dom，如何从 React 组件外部访问 browserHistory 对象? [英] Usign react-router-dom, how can I access browserHistory object from outside a React component?

问题描述

使用以前的 react-router 我能够做到这一点:

import {browserHistory} from 'react-router';

从我的 actionCreators 文件，我可以做这样的事情:

...一些异步操作已完成(例如，用户成功登录).browserHistory.push('/dashboard');

但是使用新的 react-router-dom (v4) 似乎我不能再像这样导入 browserHistory 并且访问历史对象的唯一方法是从 React 组件道具

this.props.history

在使用 react-router-dom 完成异步 redux 操作后，将我的用户重定向到新页面的方法是什么?

解决方案

withRouter 就是您要找的.

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

import React, { PropTypes } from 'react'从反应路由器"导入 { withRouter }//一个简单的组件，显示当前位置的路径名class ShowTheLocation 扩展了 React.Component {静态 propTypes = {匹配:PropTypes.object.isRequired，位置:PropTypes.object.isRequired，历史:PropTypes.object.isRequired}使成为() {const { 匹配，位置，历史} = this.props返回 (<div>您现在位于 {location.pathname}</div>)}}//创建一个连接"的新组件(借用 redux//术语)到路由器.const ShowTheLocationWithRouter = withRouter(ShowTheLocation)

With the previous react-router I was able to do this:

import {browserHistory} from 'react-router';

from my actionCreators file and I could do something like this:

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

But with the new react-router-dom (v4) it seems like I can no longer import browserHistory just like that and that the only way to access the history object is from a React components props

this.props.history

What would be a way to redirect my user to a new page after an async redux action has completed using react-router-dom?

解决方案

withRouter is what you're looking for.

"You can get access to the history object’s properties and the closest 's match via the withRouter higher-order component."

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)
