如何在我的路由中定义路由。jsx文件捕获__firebase_request_key参数值从一个URL生成的Twitter的单点登录过程后,从他们的服务器重定向?

http://localhost:8000/#/signin?_k=v9ifuf&__firebase_request_key=blablabla

我尝试了以下路由配置,但:redirectParam没有捕获提到的参数:

<Router>
  <Route path="/" component={Main}>
    <Route path="signin" component={SignIn}>
      <Route path=":redirectParam" component={TwitterSsoButton} />
    </Route>
  </Route>
</Router>

在React Router v4中,只有withRoute才是正确的方式

您可以通过withRouter高阶组件访问历史对象的属性和最近的匹配。withRouter将在包装组件呈现时将更新的匹配、位置和历史道具传递给它。

import React from 'react'
import PropTypes from 'prop-types'
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)

也许有人可以帮助解释为什么,但如果你试图从App.js页面上的新安装的Create React App中点击props来查找位置,你会得到:

无法读取未定义的属性“搜索”

即使我有App.js作为主路径:

<Route exact path='/' render={props => (

只在App.js上,使用window。地点对我来说很合适:

import queryString from 'query-string';
...
const queryStringParams = queryString.parse(window.location.search);

当你使用react route dom时,将用for match清空对象,但如果你执行以下代码,则它将用于es6组件,以及它直接用于函数组件

import { Switch, Route, Link } from "react-router-dom";

<Route path="/profile" exact component={SelectProfile} />
<Route
  path="/profile/:profileId"
  render={props => {
    return <Profile {...props} loading={this.state.loading} />;
  }}
/>
</Switch>
</div>

通过这种方式,您可以获得道具并匹配参数和配置文件id

在对es6组件进行了大量研究后,这对我来说很有效。

如果你的路由器是这样的

<Route exact path="/category/:id" component={ProductList}/>

你会得到这样的id

this.props.match.params.id

你可以检查react-router,简单地说,你可以使用代码获取查询参数,只要你在路由器中定义:

this.props.params.userId
