条件getServerSideProps

Question

我希望使用enable动态启用、禁用getServerSideProps。我试过这样做：

  if (process.env.NEXT_PUBLIC_ONOFF === 'true') {
        export const getServerSideProps: GetStaticProps = async context => {
            const { locale = 'en' } = context;
    
            return {
                props: {
                    ...(await serverSideTranslations(locale, [
                        'common',
                    ]))
                }
            };
        };
    }

然而，我得到TS错误Modifiers cannot appear here.ts(1184)。那么，如何根据env变量正确地打开和关闭serversideprops呢？

这应该是可行的：

let getServerSidePropsConditional: GetServerSideProps | undefined

if (process.env.NEXT_PUBLIC_ONOFF === 'true') {
    getServerSidePropsConditional = async () => {
        // ...
    }
} else {
    getServerSidePropsConditional = undefined
}

export const getServerSideProps = getServerSidePropsConditional
