推荐答案

你可以通过 _app.js 来实现，这样做:

You can do it from _app.js, by doing this:

res.writeHead(301, { Location: `https://${req?.headers.host}/${asPath}` })

如果您有 forvarded-proto 标头，那么您还可以检查:

If you have forvarded-proto header then you can also check:

req.headers['x-forwarded-proto'] === 'http'

否则你必须自己判断是在http还是https，例如你可以尝试解析url:

Otherwise you must determine if you are at http or https by yourself, as an example you can try parsing the url:

const url = new URL('http://example.com')
console.log(url.protocol) // output: "http:"
