nextjs 中的 middleware.js 根本不起作用

Question

import { NextResponse } from 'next/server'

const middleware = (request) => {
  if (request.nextUrl.pathname === request.nextUrl.pathname.toLocaleLowerCase())
    return NextResponse.next()
  return NextResponse.redirect(
    `${request.nextUrl.origin}${request.nextUrl.pathname.toLocaleLowerCase()}`
  )
}

export { middleware }

(Next v.12.2.3) No matter what I code, pages/middleware.js seems not running at all!

I wanna redirect uppercase urls to lowercase urls.

what should I do?

Answer 1

The documentation says :

Create a middleware.ts (or .js ) file at the same level as your pages directory

So it shouldn't be inside pages/ , but in the same directory as pages/ .
