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>

当使用React钩子时，没有访问this.props.location的权限。 要获取url参数，请使用窗口对象。
const search = window.location.search;
const params = new URLSearchParams(search);
const foo = params.get('bar');

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)
let data = new FormData();
data.append('file', values.file);
export class ClassName extends Component{
constructor(props){
super(props);
this.state = {
id:parseInt(props.match.params.id,10)
}
}
render(){
return(
//Code
{this.state.id}
);
}
this.props.params。Your_param_name将工作。
这是从查询字符串中获取参数的方法。 请执行console.log(this.props);探索所有的可能性。
React路由器v6
来源:在React路由器中获取查询字符串(搜索参数)
使用新的useSearchParams钩子和.get()方法:
const Users = () => {
const [searchParams] = useSearchParams();
console.log(searchParams.get('sort')); // 'name'
return <div>Users</div>;
};
使用这种方法，您可以读取一个或几个参数。
将参数作为一个对象:
如果你需要一次性获得所有的查询字符串参数，那么我们可以像这样使用Object.fromEntries:
const Users = () => {
const [searchParams] = useSearchParams();
console.log(Object.fromEntries([...searchParams])); // ▶ { sort: 'name', order: 'asecnding' }
return <div>Users</div>;
};
