我有一个页面:pages/conversations/[id].tsx
,其中有:
import Router, { useRouter } from 'next/router'
export default function ConversationPage() {
const router = useRouter()
...
return (
<View style={{ flex: 1, bottom: 0 }}>
<Appbar.Header style={{ zIndex: 10, elevation: 10}}>
<Appbar.BackAction onPress={() => router.back()} />
<Appbar.Content
title={' '}
/>
...
当我单击该按钮时,它将重新加载整个页面并清除状态信息。我在做什么错了?

希望这将有助于找到解决方案。
NextJS router.back()仅调用本机window.history.back()
也许您应该间接使用Router.push()返回as
参数?
<< / p>
<span onClick={() => Router.push('/post/[pid]', '/post/abc')}>
Click me
</span>

链接到具有动态路径段的路线时,必须提供 href并确保路由器知道要哪个JavaScript文件 加载。

要跟踪先前的URL,可以使用getIntialProps或getServerSideProps中req对象的req.headers中的Referer字段。
nextjs getInitialProps中的示例标头响应
