如何使用 history.push 传递道具

How to pass props with history.push

我有 2 个页面:betslip.jsx 和 receipt.jsx。

当在 betslip.jsx 中单击按钮时,我将用户重定向到 receipts.jsx,使用以下代码为 2 个道具赋值:

history.push({
    state: { authorized:true, total:10},
    pathname: '/receipt'
})
        

根据我的阅读,这应该有效,但收据中从未收到道具值,因为收据如下所示:

export default function Receipt({authorized, total}) {

    console.log('authorized: ', authorized);
    console.log('total: ', total);

    if(!authorized){
        return <Redirect to="/" />;
    }
    return (
        <div>
            <h1>hello</h1>
        </div>
    )
}

授权还是false,总数还是0(它们的初始值)。

我是不是遗漏了什么明显的东西?请指教

在你的组件中试试这个

const location = useLocation();
const {authorized, total} = location.state;

收据组件

export default function Receipt(props) {
    const location = useLocation();

    const {authorized, total} = location.state;
    console.log('authorized: ', authorized);
    console.log('total: ', total);

    if(!authorized){
        return <Redirect to="/" />;
    }
    return (
        <div>
            <h1>hello</h1>
        </div>
    )
 }

答案是在您要定向到的页面内执行此操作:

const location = useLocation();
if(location.state){
    authorized = location.state.authorized;
    total = location.state.total;
} else{
    if(!authorized){
        return <Redirect to="/" />;
    }
}
