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-Dom V5中
function useQeury() {
const [query, setQeury] = useState({});
const search = useLocation().search.slice(1);
useEffect(() => {
setQeury(() => {
const query = new URLSearchParams(search);
const result = {};
for (let [key, value] of query.entries()) {
result[key] = value;
}
setQeury(result);
}, [search]);
}, [search, setQeury]);
return { ...query };
}
// you can destruct query search like:
const {page , search} = useQuery()
// result
// {page : 1 , Search: "ABC"}

有了这一行代码，你可以在React Hook和React Class Component的任何地方使用它。
https://www.hunterisgod.com/?city=Leipzig
let city = (new URLSearchParams(window.location.search)).get("city")
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();
更多的在这里。
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');
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)
http://localhost:8000/#/signin?id=12345
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);//12345
}
