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
componentDidMount(){
//http://localhost:3000/service/anas
//<Route path="/service/:serviceName" component={Service} />
const {params} =this.props.match;
this.setState({
title: params.serviceName ,
content: data.Content
})
}

React路由器v4
使用组件
<Route path="/users/:id" component={UserPage}/>
this.props.match.params.id
该组件自动使用路由道具呈现。
使用渲染
<Route path="/users/:id" render={(props) => <UserPage {...props} />}/>
this.props.match.params.id
路由道具被传递给渲染函数。
最受欢迎的答案中的链接是死的，因为SO不让我评论，对于ReactRouter v6.3.0，你可以使用params钩子
import * as React from 'react';
import { Routes, Route, useParams } from 'react-router-dom';
function ProfilePage() {
// Get the userId param from the URL.
let { userId } = useParams();
// ...
}
function App() {
return (
<Routes>
<Route path="users">
<Route path=":userId" element={<ProfilePage />} />
<Route path="me" element={...} />
</Route>
</Routes>
);
}
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)

假设有一个url如下所示
http://localhost:3000/callback?code=6c3c9b39-de2f-3bf4-a542-3e77a64d3341
如果我们想从该URL提取代码，下面的方法将工作。
const authResult = new URLSearchParams(window.location.search);
const code = authResult.get('code')
http://localhost:8000/#/signin?id=12345
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);//12345
}
