reactjs - 无法导出带有 getServerSideProps 的 nextjs 页面

Question

我最近开始学习和使用 next.js，我已经构建了一个简单的 cpanel 页面，它应该在每次请求页面时获取数据(如 react 的 useEffect 钩子(Hook))，所以我尝试使用 getServerSideProps，它运行良好本地开发服务器，但是当我执行 npm run dev (运行下一个构建 && 下一个导出)时，它开始构建，然后当它开始导出时，它给了我这个错误:Error occurred prerendering page "/". Read more: https://err.sh/next.js/prerender-error Error: Error for page /: pages with getServerSideProps can not be exported. See more info here: https://err.sh/next.js/gssp-export .
我真的很困惑，从最后一天开始我一直在尝试用谷歌搜索这个问题，但找不到任何有用的东西，现在如果我找不到任何解决方案，我将只使用 react 的 useEffect 钩子(Hook)来获取 Prop ，但是你知道，getServerSideProps 更好，因为它在渲染页面之前获取 Prop ，从而提升页面。
这是 index.js 页面代码:

//  /pages/index.js

import Layout from "../components/Layout/Layout.js";
import PanelWrapper from "../components/panel/panelWrapper.js";
import getEnrolls from "../components/fetch/fetch.js";
import { API } from "../exports/config.js";

const PanelPage = ({ all, pending, accepted }) => {
  const [allEnrolls, setAllEnrolls] = React.useState(all);
  const [pendingEnrolls, setPendingEnrolls] = React.useState(pending);
  const [acceptedEnrolls, setAcceptedEnrolls] = React.useState(accepted);

  const [status, setStatus] = React.useState("all");

  const [allPage, setAllPage] = React.useState(allEnrolls.currentPage);
  const [pendingPage, setPendingPage] = React.useState(
    pendingEnrolls.currentPage
  );
  const [acceptedPage, setAcceptedPage] = React.useState(
    acceptedEnrolls.currentPage
  );

  //some functions in here
  return (
    <Layout>
      <PanelWrapper
        all={allEnrolls}
        pending={pendingEnrolls}
        accepted={acceptedEnrolls}
      />
    </Layout>
  );
};

export const getServerSideProps = async () => {
  const { all, pending, accepted } = await getEnrolls();
  return {
    props: {
      all,
      pending,
      accepted,
    },
  };
};

export default PanelPage;

请注意:PanelPage 函数中不需要使用 state 并从解构的 props 对象中分配值。您的代码可以更短、更干净。
我也对你的 getServerSideProps 做了一些小改动功能一样。

import react, { useState } from "react";
import Layout from "../components/Layout/Layout.js";
import PanelWrapper from "../components/panel/panelWrapper.js";
import getEnrolls from "../components/fetch/fetch.js";
import { API } from "../exports/config.js";

const PanelPage = ({ all, pending, accepted }) => {
  const [status, setStatus] = useState("all");

  const [allPage, setAllPage] = useState(all.currentPage);
  const [pendingPage, setPendingPage] = useState(
    pending.currentPage
  );
  const [acceptedPage, setAcceptedPage] = useState(
    accepted.currentPage
  );

  //some functions in here
  return (
    <Layout>
      <PanelWrapper
        all={all}
        pending={pending}
        accepted={accepted}
      />
    </Layout>
  );
};

export async function getServerSideProps() {
  const res = await getEnrolls();
  const { all, pending, accepted } = await res.json();

  return {
    props: {
      all,
      pending,
      accepted,
    },
  };
};

export default PanelPage;
