nextjs Router.back刷新整个页面

标签: javascript react-router next.js

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()

这是源代码https://github.com/zeit/next.js/blob/d21603707edfaab292cb3190881efda9a07195cd/lib/router/router.js#L138

也许您应该间接使用Router.push()返回as参数?

<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

headers: {
    host: 'localhost:3000',
    connection: 'keep-alive',
    'upgrade-insecure-requests': '1',
