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
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)
其他回答
假设有一个url如下所示
http://localhost:3000/callback?code=6c3c9b39-de2f-3bf4-a542-3e77a64d3341
如果我们想从该URL提取代码，下面的方法将工作。
const authResult = new URLSearchParams(window.location.search);
const code = authResult.get('code')
当你使用react route dom时，将用for match清空对象，但如果你执行以下代码，则它将用于es6组件，以及它直接用于函数组件
import { Switch, Route, Link } from "react-router-dom";
<Route path="/profile" exact component={SelectProfile} />
<Route
path="/profile/:profileId"
render={props => {
return <Profile {...props} loading={this.state.loading} />;
}}
/>
</Switch>
</div>
通过这种方式，您可以获得道具并匹配参数和配置文件id
在对es6组件进行了大量研究后，这对我来说很有效。
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>
);
}
从v4开始，React路由器不再直接在其location对象中提供查询参数。原因是
There are a number of popular packages that do query string parsing/stringifying slightly differently, and each of these differences might be the "correct" way for some users and "incorrect" for others. If React Router picked the "right" one, it would only be right for some people. Then, it would need to add a way for other users to substitute in their preferred query parsing package. There is no internal use of the search string by React Router that requires it to parse the key-value pairs, so it doesn't have a need to pick which one of these should be "right".
包含了这个之后，只解析location会更有意义。在需要查询对象的视图组件中搜索。
你可以通过覆盖react-router中的withRouter来实现这一点
customWithRouter.js
import { compose, withPropsOnChange } from 'recompose';
import { withRouter } from 'react-router';
import queryString from 'query-string';
const propsWithQuery = withPropsOnChange(
['location', 'match'],
({ location, match }) => {
return {
location: {
...location,
query: queryString.parse(location.search)
},
match
};
}
);
export default compose(withRouter, propsWithQuery)
最简单的解决方案!
在路由方面:
<Route path="/app/someUrl/:id" exact component={binder} />
在react代码中:
componentDidMount() {
var id = window.location.href.split('/')[window.location.href.split('/').length - 1];
var queryString = "http://url/api/controller/" + id
$.getJSON(queryString)
.then(res => {
this.setState({ data: res });
});
}
