我正在做一个新项目，最近使用了nextjs13作为我的前端应用程序。
当与next/header库函数headers()一起使用generateStaticParams函数时，
在dev模式下出现错误。
未处理的运行时错误-动态服务器使用:headers
在开发模式下出现错误的截图
但是当前端使用下一个构建/下一个启动时，错误不会出现
我使用next/header库的主要原因是由于next-auth，以获得访问cookie的权限。
generateStaticParams在app/detail/[questionId]/page.tsx文件中next/headers在app/layout.tsx文件
app/page.tsx
import React from "react";
import QuestionCard from "../components/Card/QuestionCard";
import Carousel from "../components/Carousel/Carousel";

const getGoogleSession = async () => {};
const getQuestionList = async () => {
const response = await fetch(`https://pioneroroom.com/questionlist`);
const data = await response.json();
return data;
};
const page = async ({ Question }: any) => {
// const imageArr = await getCarouselImages();
const data = await getQuestionList();
return (
<div className="main">
<HomeNavBar />
{/* <Carousel carousel={imageArr} /> */}
<div className="contentbody">
{data.data.map((e: any) => {
return <QuestionCard key={e.questionId} question={e} />;
})}
</div>
<TabNavigator activeLink={""} />
</div>
);
};
export default page;

const RootLayout = async ({ children }: any) => {
const { segment } = children.props.childProp;
const session = await getSession(headers().get('cookie') ?? '');
const nextCookies = cookies();
return (

export default RootLayout;
应用程序/细节/[questionId]/page.tsx
import { headers } from 'next/headers';
import React, { use } from 'react';
import { getSession } from '../../../utils/helper/session';

};
// BUG: generateStaticParams 함수가 현재 dev 모드에서 동작하지 않음.
// dynamic headers( next/headers )의 cookie등을 불러올 때 오류를 일으키고,
// dev mode에서 이 함수와 결합하여 사용하면 dynamic server usage: headers error 발생함.

export default DetailIdPage;
删除两个代码(generateStaticParams or next/header)解决了这个问题。在dev模式下没有错误。
我用来阻止这些错误发生的解决方案是在开发模式下完全关闭静态渲染。(但保持在prod中)
要导出的文件中的generateStaticParams()
// what used to be export function generateStaticParams
function staticParams(){
...
}
// fix "dynamic server usage" errors in dev mode by turning off static generation and forcing dynamic rendering
export const generateStaticParams = process.env.NODE_ENV === "production" ? staticParams : undefined;
export const dynamic = process.env.NODE_ENV === "production" ? 'auto' : 'force-dynamic';
