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>

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');
其他回答
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。
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) ｝

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
})
}
