问题描述

我正在尝试在登录后实现重定向.但是在进入登录页面时会传递自定义路由，这会因按下哪个按钮等而异.

I'm trying to implement a redirect after logging in. But there will be custom routes passed when getting to the login page which varies on which button is pressed etc.

import { useLocation } from 'react-router-dom';

const Login: FC = (): JSX.Element => {
 const location = useLocation();
 const [claimUrl, setClaimUrl] = useState({});
 useEffect(() => {
        location.state && setClaimUrl(location.state.claimUrl);
    }, [location]);
...
};

我收到一个错误:属性claimUrl"在类型{}"上不存在.

那么有没有办法在位置上定义它?

So is there a way I can define it on the location?

任何帮助/建议都会很棒.

Any help/advice would be great.

推荐答案

通过将字段添加到 useLocation() 设法解决了这个问题.

Managed to figure this out by adding the field to useLocation().

const location = useLocation<{
        claimUrl: unknown;
    }>();
