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>

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))
其他回答
在需要访问可以使用的参数的组件中
this.props.location.state.from.search
这将显示整个查询字符串(在?标志)
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。
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>;
}
React路由器Dom V6 https://reactrouter.com/docs/en/v6/hooks/use-search-params
import * as React from "react";
import { useSearchParams } from "react-router-dom";
function App() {
let [searchParams, setSearchParams] = useSearchParams();
function handleSubmit(event) {
event.preventDefault();
// The serialize function here would be responsible for
// creating an object of { key: value } pairs from the
// fields in the form that make up the query.
let params = serializeFormQuery(event.target);
setSearchParams(params);
}
return (
<div>
<form onSubmit={handleSubmit}>{/* ... */}</form>
</div>
);
}
直到React路由器Dom V5
function useQueryParams() {
const params = new URLSearchParams(
window ? window.location.search : {}
);
return new Proxy(params, {
get(target, prop) {
return target.get(prop)
},
});
}
React钩子很棒
如果你的url看起来像/users?页面= 2数= 10字段=姓名、电子邮件、电话
// app.domain.com/users?page=2&count=10&fields=name,email,phone
const { page, fields, count, ...unknown } = useQueryParams();
console.log({ page, fields, count })
console.log({ unknown })
如果您的查询参数包含hyphone("-")或空格(" ") 然后你不能像{page, fields, count，…未知的}
你需要做传统的作业，比如
// app.domain.com/users?utm-source=stackOverFlow
const params = useQueryParams();
console.log(params['utm-source']);
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) ｝
