[英]Next.js intercept response
Here is snippet of what my server looks like这是我的服务器的片段
nextApp.prepare().then(() => {
createServer((req, res) => {
const parsedUrl = parse(req.url!, true);
handleNextRequest(req, res, parsedUrl);
}).listen(port);
});
Once I get the response for the request, how can I append html comment or any tag basically?一旦我得到请求的响应,我如何基本上附加 html 注释或任何标签?
What I wanted to do is, before and after body tag, I want to add some comments.我想做的是,在body标签之前和之后,我想添加一些评论。
<body></body>
<!--someContext-->
<body> some content </body>
<!--someMoreContext-->
You can do it by editing the _document
special file of Next that used as a base template to the page.您可以通过编辑用作页面基本模板的 Next 的
_document
特殊文件来实现。
// ./pages/_document.js
import Document, { Html, Head, Main, NextScript } from 'next/document'
class MyDocument extends Document {
static async getInitialProps(ctx) {
const initialProps = await Document.getInitialProps(ctx)
return { ...initialProps }
}
render() {
return (
<Html>
<Head />
<body>
<Main />
<NextScript />
</body>
</Html>
)
}
}
export default MyDocument
