定义路由
我们建议你先阅读 路由基础知识 页,然后再继续。
¥We recommend reading the Routing Fundamentals page before continuing.
本页面将指导你如何在 Next.js 应用中定义和组织路由。
¥This page will guide you through how to define and organize routes in your Next.js application.
创建路由
¥Creating Routes
Next.js 使用基于文件系统的路由,其中使用文件夹来定义路由。
¥Next.js uses a file-system based router where folders are used to define routes.
每个文件夹代表一个映射到 URL 段的 路由片段。要创建 嵌套路由,你可以将文件夹相互嵌套。
¥Each folder represents a route segment that maps to a URL segment. To create a nested route, you can nest folders inside each other.
特殊的 page.js
file 用于使路由段可公开访问。
¥A special page.js
file is used to make route segments publicly accessible.
在此示例中,/dashboard/analytics
URL 路径不可公开访问,因为它没有相应的 page.js
文件。该文件夹可用于存储组件、样式表、图片或其他并置文件。
¥In this example, the /dashboard/analytics
URL path is not publicly accessible because it does not have a corresponding page.js
file. This folder could be used to store components, stylesheets, images, or other colocated files.
很高兴知道:
.js
、.jsx
或.tsx
文件扩展名可用于特殊文件。¥Good to know:
.js
,.jsx
, or.tsx
file extensions can be used for special files.
创建用户界面
¥Creating UI
特殊文件约定 用于为每个路由段创建 UI。最常见的是 pages 显示路由独有的 UI,layouts 显示跨多个路由共享的 UI。
¥Special file conventions are used to create UI for each route segment. The most common are pages to show UI unique to a route, and layouts to show UI that is shared across multiple routes.
例如,要创建第一个页面,请在 app
目录中添加 page.js
文件并导出 React 组件:
¥For example, to create your first page, add a page.js
file inside the app
directory and export a React component:
export default function Page() {
return <h1>Hello, Next.js!</h1>
}
export default function Page() {
return <h1>Hello, Next.js!</h1>
}
