我尝试在NextJS 13中动态更新元数据。为此，我有一个rest API作为后端，它发送像title, description, keywords, images etc这样的元数据。我的目标是，通过这种方法，我可以随时更新网站的元数据。但问题是，在应用此之后，它在我的本地服务器上工作正常，但一旦我将其托管到vercel服务器上，它就不能像我想要的那样工作了。它获取了一次数据，但当我在API中更改数据时，它不会在网站中更新。
下面是我所做的代码示例，

• 在about-us/page.tsx中使用此函数

export async function generateMetadata(): Promise<Metadata> {
    const meta = await getMetaApi("about");
    return {
        title: `${meta?.data?.page_name} | Legato Designs `,
        generator: "Legato Designs",
        applicationName: "Legato Designs",
        keywords: meta?.data?.meta_keywords?.split(","),
        authors: [{name: 'Golden Infotech Ltd'}, {name: 'Golden Infotech Ltd', url: 'https://goldeninfotech.com.bd/'}],
        creator: 'Golden Infotech Ltd',
        publisher: 'Legato Designs',
        metadataBase: new URL("https://legatodesigns.com/"),
        alternates: {
            canonical: '/',
            languages: {
                'en-US': '/en-US',
                'de-DE': '/de-DE',
            },
        },
        openGraph: {
            title: meta?.data?.og_title,
            description: meta?.data?.og_description,
            url: 'https://legatodesigns.com/',
            siteName: 'Legato Designs',
            images: [
                {
                    url: `${process.env.NEXT_PUBLIC_BASE_URL_IMG_ALT}${meta?.data?.og_image}`,
                    width: 800,
                    height: 600,
                },
                {
                    url: `${process.env.NEXT_PUBLIC_BASE_URL_IMG_ALT}${meta?.data?.meta_image}`,
                    width: 1800,
                    height: 1600,
                    alt: 'Legato Designs',
                },
            ],
            locale: 'en-US',
            type: 'website',
        },
        twitter: {
            card: 'summary_large_image',
            title: meta?.data?.og_title,
            description: meta?.data?.og_description,
            creator: '@goldeninfotech',
            images: [`${process.env.NEXT_PUBLIC_BASE_URL_IMG_ALT}${meta?.data?.og_image}`],
        },
        robots: {
            index: true,
            follow: true,
            nocache: true,
            googleBot: {
                index: true,
                follow: false,
                noimageindex: true,
                'max-video-preview': -1,
                'max-image-preview': 'large',
                'max-snippet': -1,
            },
        },
        icons: {
            icon: '/legato_fav.png',
            shortcut: '/legato_fav.png',
            apple: '/legato_fav.png',
            other: {
                rel: '/legato_fav',
                url: '/legato_fav.png',
            },
        },
        manifest: 'https://nextjs.org/manifest.json',

    };
}

• getMetaApi函数代码

export const getMetaApi = async (page) => {
    try {
        const response = await Axios.get(`get-meta/${page}`);
        return response.data;
    } catch (err) {
        console.log(err)
    }
}
