NextJS路由错误,换页时,尝试打开错误文件

问题描述

我想要什么

我想切换页面而不用再想我要打开另一个页面

问题

我有这个奇怪的路由问题。 一、我的文件夹结构

pages
  [app]
    [object]
      index.js
    index.js
    manager.js
    Feed.js

我在此路径 /[app] 并导航到 /[app]/manager,然后我想导航到 /[app]/Feed 并且我收到此未处理的运行时错误。 >

TypeError: Cannot read property "title" of undefined

错误来自 [object] index.js。堆栈跟踪在下面。当然,它无法读取标题是有道理的,因为我正在尝试打开另一个页面。然而它认为我正在尝试打开 [object]。 这个错误不时发生,但我尝试打开页面的顺序无关紧要,可以是经理提供或提供给经理,或者我在那里拥有的任何其他内容。 我的 getStaticPathsgetStaticProps 在所有这些页面上都是一样的,我将与 manager.js 共享一个

export const getStaticPaths = async () => {
  const paths = appRoutes.map((appRoute) => {
    const slug = appRoute.slug;

    return {
      params: {
        app: slug,manager: 'manager',},};
  });

  return {
    fallback: false,paths,};
};

export const getStaticProps = async ({ locale }) => {
  return {
    props: {
      ...(await serverSideTranslations(locale,['manager','common'])),};
};

同样如此,但对于 [object]

export const getStaticPaths = async () => {
  const allObjects = await loadobjectData({ id: 'all' });
  const paths = allObjects.flatMap((object) => {
    return appRoutes.map((appRoute) => {
      return {
        params: {
          object: object.type,app: appRoute.slug,};
    });
  });

  return {
    fallback: false,};
};

export const getStaticProps = async ({ params,locale }) => {
  const object = await loadobjectData({ type: params.object });
  const app = appRoutes.find((appRoute) => appRoute?.slug === params.app);

  if (!object) {
    throw new Error(
      `${object} is not a valid Object. Try checking out your parameters: ${params.object}`
    );
  }

  if (!app) {
    throw new Error(`${app} is not a valid App.`);
  }

  return {
    props: {
      ...(await serverSideTranslation(locale,['common'])),object,app,};
};

这个错误很难重现,因为它只是偶尔发生。


新编辑

这是[object]/index.js的完整文件

import appRoutes from '../../../routes/appRoutes';
import loadobjectData from '../../../utils/loadobjects';
import { serverSideTranslation } from 'next-i18next/serverSideTranslations';

export default function ObjectPage({ object }) {
  return <h1> {object.title} </h1>;
}

export const getStaticPaths = async () => {
  const allObjects = await loadobjectData({ id: 'all' });
  const paths = allObjects.flatMap((object) => {
    return appRoutes.map((appRoute) => {
      return {
        params: {
          object: object.type,};
};

堆栈跟踪:

25.06.2021

所以我从 ObjectPage 和每个 NavigationItem 控制台记录了路由器。我注意到了一些奇怪的事情。
这是我传递给 <Link> 的 href:

{
  pathname: "/[app]/[menuItem]"
  query: {
    app: "content"
    menuItem: "files"
  }
}

这是我在 ObjectPage 上返回的完整路由器。

{
asPath: "/content/editor" // this the path i want to open
back: ƒ ()
basePath: ""
beforePopState: ƒ ()
components: {
  "/[app]/[object]": {styleSheets: Array(0),__N_SSG: true,__N_ssp: undefined,props: {…},Component: ƒ}
  "/[app]/editor": {initial: true,err: undefined,Component: ƒ,…}
  "/_app": {styleSheets: Array(0),Component: ƒ}
}
defaultLocale: "de"
events: {on: ƒ,off: ƒ,emit: ƒ}
isFallback: false
isLocaleDomain: false
isPreview: false
isReady: true
locale: "de"
locales: ["de"]
pathname: "/[app]/[object]" // [object] is being loaded
prefetch: ƒ ()
push: ƒ ()
query: {app: "content",menuItem: "editor",object: "editor"} // this is interesting
reload: ƒ ()
replace: ƒ ()
route: "/[app]/[object]" // same as pathname
}

query 中,您可以看到 object 被注入。但我不知道从哪里以及为什么。

解决方法

我有这个代码:

{
  pathname: "/[app]/[menuItem]"
  query: {
    app: "content"
    menuItem: "files"
  }
}

这是不正确的,因为没有到 [menuItem] 的动态路径。所以我写了:

{
  pathname: "/[app]/files"
  query: {
    app: "content"
  }
}

解决了我遇到的问题。

我误解了参数的文档。
