Description
参照这个文档的步骤，在项目里面添加了状态管理用户相关信息
https://rax.js.org/docs/guide/miniapp-store
Home页面
export default function Home() {
const [userState, userDispatchers] = store.useModel('user');
useEffect(() => {
//这里异步获取用户信息并使用userDispatchers.update({userInfo}) 保管用户信息
}
}
页面上按钮点击时通过history.push('/otherPage')跳转到其他页面， 在这个otherPage上点击返回按钮返回到Home页面，使用userState时得到undefined？ 为什么会这个样子，期望帮忙解答一下这个问题
