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>

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>
);
}

你也可以使用react-location-query包，例如:
const [name, setName] = useLocationField("name", {
type: "string",
initial: "Rostyslav"
});
return (
<div className="App">
<h1>Hello {name}</h1>
<div>
<label>Change name: </label>
<input value={name} onChange={e => setName(e.target.value)} />
</div>
</div>
);
名称-获取价值 setName =设置值
这个包有很多选项，在Github上的文档中阅读更多
你可以使用这个用Typescript写的简单钩子:
const useQueryParams = (query: string = null) => {
const result: Record<string, string> = {};
new URLSearchParams(query||window.location.search).forEach((value, key) => {
result[key] = value;
});
return result;
}
用法:
// http://localhost:3000/?userId=1889&num=112
const { userId, num } = useQueryParams();
// OR
const params = useQueryParams('userId=1889&num=112');
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);
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))
使用let {redirectParam} = useParams();如果你用的是功能组件
它是一个类组件
constructor (props) {
super(props);
console.log(props);
console.log(props.match.params.redirectParam)
}
async componentDidMount(){
console.log(this.props.match.params.redirectParam)
}
