javascript - 如何访问 Next.JS 自定义 404 页面上的当前路由？

Question

我的 Next.JS 应用程序 (404.js) 中有一个自定义 404 页面。在页面上，我想显示一条消息The route <strong>/not-a-route</strong> does not exist，但是当使用 Next.jsuseRouter()和router.pathname时，路由器认为我打开了/404，而是显示The route <strong>/404</strong> does not exist. 如何访问我在自定义 404 页面中的实际路线？

export const NotFound: React.FC = () => {
  const router = useRouter();
  console.log(router.pathname) // prints /404
  return (
    <Layout title='Oops! Something went wrong!'>
      <div className={styles.container}>
        <h1>Oops! Something went wrong!</h1>
          <p>
            The route <strong>{router.pathname}</strong> does not exist.
          </p>
      </div>
    </Layout>
  );
};

您可以访问redirected routeas router.asPath。尝试：

import {useRouter} from 'next/router'
export const NotFound: React.FC = () => {
  const router = useRouter();
  console.log(router.asPath)
  return (
    <Layout title='Oops! Something went wrong!'>
      <div className={styles.container}>
        <h1>Oops! Something went wrong!</h1>
          <p>
            The route <strong>{router.asPath}</strong> does not exist.
          </p>
      </div>
    </Layout>
  );
};
