javascript - Nextjs 页面刷新总是把我带到 index.js

标签 javascript reactjs routes next.js

我不明白为什么当我在 nextjs 应用程序中刷新页面时,我总是回到索引页面。
我在 index.js 中有一个带有目录页面的电子商务 SPA,并且产品通过动态 [name].js 页面显示。如果我通过浏览器刷新或后退按钮导航,则路由是一团糟。我想我错过了 nextjs 的良好实践中的一些东西。
index.js

import Head from "next/head";
import Catalogue from "../../components/Catalogue";
import { getProducts } from "../../utils/api";

const HomePage = ({ products }) => {
  return (
    <div>
      <Head>
        <title>Catalogue</title>

  );
};

export async function getStaticProps() {
  const products = await getProducts();
  return { props: { products } };
}

export default HomePage;
[名称].js
const ProductPage = ({ product }) => {

  const router = useRouter();

  );
};

export default ProductPage;

export async function getStaticProps({ params }) {
  const product = await getProduct(params.name);
  return { props: { product } };
}

// This function gets called at build time
export async function getStaticPaths() {
  // Call an external API endpoint to get products
  const products = await getProducts();
  // Get the paths we want to pre-render based on posts
  const paths = products.map(
    (product) => `/books/${product.name}`
  );
  // We'll pre-render only these paths at build time.
  // { fallback: false } means other routes should 404.
  return { paths, fallback: false };
}
我在 nextjs 文档上读到了这个,它可以成为解决方案的一部分吗?

If the page uses an optional catch-all route, supply null, [], undefined or false to render the root-most route. For example, if you supply slug: false for pages/[[...slug]], Next.js will statically generate the page /.

最佳答案

paths 的格式在 getStaticPaths是错的。
这是文档。
https://nextjs.org/docs/basic-features/data-fetching#getstaticpaths-static-generation

export async function getStaticPaths() {
  // Call an external API endpoint to get products
  const products = await getProducts();
  // Get the paths we want to pre-render based on posts
  const paths = products.map(
    (product) => ({ params: { name: product.name } })
  );
  // We'll pre-render only these paths at build time.
  // { fallback: false } means other routes should 404.
  return { paths, fallback: false };
}


更新

我已经在本地和 CSB 上尝试过您的代码,它似乎按预期工作。
你说它只发生在生产环境中,你在哪里部署它?
部署过程中可能存在问题,因此您可能需要联系您的服务提供商。
另外,我想知道您将 pages 目录放在哪里。 nextjs 要求 pages 目录位于根目录或 src目录。
