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)

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');

容易解构分配URLSearchParams
测试尝试如下:
1
扫描:https://www.google.com/?param1=apple¶m2=banana
2
右键单击>页,单击Inspect > goto Console选项卡
然后粘贴下面的代码:
const { param1, param2 } = Object.fromEntries(new URLSearchParams(location.search));
console.log("YES!!!", param1, param2 );
输出:
YES!!! apple banana
你可以扩展params,如param1, param2,想扩展多少就扩展多少。
