我们如何在React-Router v4中通过this.props.history.push('/page')传递参数?
.then(response => {
var r = this;
if (response.status >= 200 && response.status < 300) {
r.props.history.push('/template');
});

For the earlier versions: history.push('/[pathToSomeWhere]', yourData); And get the data in the related component just like below: this.props.location.state // it is equal to yourData For the newer versions the above way works well but there is a new way: history.push({ pathname: '/[pathToSomeWhere]', state: yourData, }); And get the data in the related component just like below: Class Component this.props.location.state; // it is equal to yourData Function Component const location = useLocation(); location.state; // it is equal to yourData
有时需要使用Link或NavLink组件,而不是使用历史记录。推动作用。你可以用下面的like:
<Link
to={{
pathname: '/[pathToSomeWhere]',
state: yourData
}}
>
...
</Link>
提示:状态键名称应在最新版本中使用。

带有钩子的React TypeScript
来自班级
this.history.push({
pathname: "/unauthorized",
state: { message: "Hello" },
});
未经授权的功能组件
interface IState {
message?: string;
}
export default function UnAuthorized() {
const location = useLocation();
const message = (location.state as IState).message;
return (
<div className="jumbotron">
<h6>{message}</h6>
</div>
);
}
添加信息以获取查询参数。
const queryParams = new URLSearchParams(this.props.location.search);
console.log('assuming query param is id', queryParams.get('id');
有关URLSearchParams的更多信息,请查看此链接 URLSearchParams
你可以用,
this.props.history。Push ("/template",{…响应}) 或 this.props.history。推送("/template", {response: response})
然后,您可以通过以下代码访问/template组件中的解析数据:
Const state = this.props.location.state

扩展解决方案(由Shubham Khatri建议)用于React钩子(16.8起):
package.json (always worth updating to latest packages)
{
...
"react": "^16.12.0",
"react-router-dom": "^5.1.2",
...
}
使用历史推送传递参数:
import { useHistory } from "react-router-dom";
const FirstPage = props => {
let history = useHistory();
const someEventHandler = event => {
history.push({
pathname: '/secondpage',
search: '?query=abc',
state: { detail: 'some_value' }
});
};
};
export default FirstPage;
从'react-router-dom'中使用useLocation访问传递的参数:
import { useEffect } from "react";
import { useLocation } from "react-router-dom";
const SecondPage = props => {
const location = useLocation();
useEffect(() => {
console.log(location.pathname); // result: '/secondpage'
console.log(location.search); // result: '?query=abc'
console.log(location.state.detail); // result: 'some_value'
}, [location]);
};
没有必要与throuter一起使用。这对我来说很管用:
在父页面中,
<BrowserRouter>
<Switch>
<Route path="/routeA" render={(props)=> (
<ComponentA {...props} propDummy={50} />
)} />
<Route path="/routeB" render={(props)=> (
<ComponentB {...props} propWhatever={100} />
)} />
</Switch>
</BrowserRouter>
然后在ComponentA或ComponentB中进行访问
this.props.history
对象,包括this.props.history.push方法。
