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
React路由器v5.1引入了钩子:
For
<Route path="/posts/:id">
<BlogPost />
</Route>
你可以通过hook访问params / id:
const { id } = useParams();

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
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
React Router v4不再有props.location.query对象(见github讨论)。因此，已接受的答案将不适用于较新的项目。
v4的解决方案是使用外部库查询字符串来解析props.location.search
const qs = require('query-string');
//or
import * as qs from 'query-string';
console.log(location.search);
//=> '?foo=bar'
const parsed = qs.parse(location.search);
console.log(parsed);
//=> {foo: 'bar'}
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))
React路由器5.1+
5.1引入了各种钩子，如useLocation和useParams，可以在这里使用。
例子:
<Route path="/test/:slug" component={Dashboard} />
如果我们去参观
http://localhost:3000/test/signin?_k=v9ifuf&__firebase_request_key=blablabla
你可以把它找回来
import { useLocation } from 'react-router';
import queryString from 'query-string';
const Dashboard: React.FC = React.memo((props) => {
const location = useLocation();
console.log(queryString.parse(location.search));
// {__firebase_request_key: "blablabla", _k: "v9ifuf"}
...
return <p>Example</p>;
}
