我试图向用户显示两种字体,但没有 FOIT,而是有一个 FOUT,我希望用户不要在每次重新访问页面时重新下载字体。

我添加了字体观察器以添加额外的 FOUT 后备功能。_document.js

  componentWillMount() {
if (process.browser) {
const html = document.documentElement;
html.classList.add('fonts-loading');
const fontPoppins = new FontFaceObserver('Poppins');
fontPoppins.load(null, 5000).then(() => {
console.log('Poppins font has loaded.');
html.classList.remove('fonts-loading');
html.classList.add('fonts-loaded');
}).catch(() => {
html.classList.remove('fonts-loading');
html.classList.add('fonts-failed');
});
const fontAvenir = new FontFaceObserver('Avenir');
fontAvenir.load(null, 5000).then(() => {
console.log('Avenir font has loaded.');
}).catch(() => {
html.classList.remove('fonts-loading');
html.classList.add('fonts-failed');
});
}
}
... (more code here)

render ( code here ) ...

// Additional FOUT?
<Head>
<link
href="https://fonts.googleapis.com/css?family=Poppins:200,300,400,600,700,800,900&display=swap"
rel="preload"
as="font"
/>
... (more code here)
</Head>

样式.css

html {
font-family: sans-serif;
-webkit-font-smoothing: antialiased;
}

.fonts-loaded html {
font-family: Avenir, sans-serif;
}


@font-face {
font-family: Avenir;
src: url('/static/fonts/Avenir.ttc');
font-display: swap;
font-style: normal;
}

@font-face {
font-family: Poppins;
src: url('/static/fonts/Poppins-Regular.ttf');
font-weight: 400;
font-style: normal;
font-display: swap;
}

最佳答案

使用 next.js 自定义服务器,您可以为每个文件设置缓存控制。

https://github.com/zeit/next.js/#custom-server-and-routing

const parsedUrl = parse(req.url, true)
const { pathname, query } = parsedUrl

if(pathname === '/static/fonts/Avenir.ttc' || pathname === '/static/fonts/Poppins-Regular.ttf') {
res.setHeader('Cache-Control', 'public,max-age=31536000');
}

对于 Google Font,它看起来像缓存控制已经设置。
