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>

当前回答

在需要访问可以使用的参数的组件中

this.props.location.state.from.search

这将显示整个查询字符串(在?标志)

其他回答

或者像这样?

Let win = { “位置”:{ “路径”:“http://localhost: 8000 / # / signin吗?_k = v9ifuf&__firebase_request_key =之类的 } } If (win.location.path.match('__firebase_request_key').length) { 让key= win.location.path.split('__firebase_request_key=')[1] console.log(关键) }

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

您可以使用这段代码来获取作为对象的参数。如果url中没有查询参数,该对象将为空

let url = window.location.toString(); Let params = url?.split("?")[1]?.split("&"); 让obj = {}; params?.forEach((el) => { Let [k, v] = el?.split("="); obj[k] = v.replaceAll("%20", " " "); }); console.log (obj);

试试这个

http://localhost:4000/#/amoos?id=101

// ReactJS
import React from "react";
import { useLocation } from "react-router-dom";

const MyComponent = () => {
    const search = useLocation().search;
    const id = new URLSearchParams(search).get("id");
    console.log(id); //101
}



// VanillaJS
const id = window.location.search.split("=")[1];
console.log(id); //101

如果你没有得到这个。道具…根据其他答案,您可能需要使用withthrouter (docs v4):

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 TwitterSsoButton = withRouter(ShowTheLocation)  

// This gets around shouldComponentUpdate
withRouter(connect(...)(MyComponent))

// This does not
connect(...)(withRouter(MyComponent))
