Reactjs 如何在中间件中获取 nextAuth 会话

我已经使用nextAuth和Next js 4.23.1创建了一个会话，并且它可以工作，但是我不知道如何在我的中间件中获取会话或令牌，我try 将处理程序传递给getSession()并执行任何工作.

我可以通过useSession在任何Use CLINTE组件中获取会话

我如何在服务器端获得会话和/或令牌，谢谢您的帮助

in api/auth/[..nextauth]/route个

import NextAuth from "next-auth"
import CredentialsProvider from "next-auth/providers/credentials"
import { _AUTH } from "@/app/services/shared/endpoints";

export const handler = NextAuth({
    session: {
      strategy: 'jwt'
    },

    providers: [
      CredentialsProvider({
        async authorize(credentials, req){
            const res  = await fetch(_AUTH._AUTH_LOGIN, {
                method: 'POST',
                body: JSON.stringify({user:{...credentials}}),
                headers: { "Content-Type": "application/json" }
            })
               const user = await res.json()
               if (!user) {
                  return
                } else {
                  return user
                }
            }
        })
    ],
      pages: {
        signIn: '/login',
      }
})
  
export { handler as GET, handler as POST }

middleware个

import { handler } from "./app/api/auth/[...nextauth]/route"
import { NextResponse } from 'next/server'
import type { NextRequest } from 'next/server'
import { getSession } from "next-auth/react"


export async function middleware(request: NextRequest) {

    const session = await getSession(handler)

    if(session !== undefined || session !== null){
        return NextResponse.redirect(new URL('/empresa/mis-empresas', request.url))
    }
}
 
export const config = {
  matcher: [
    '/empresa/mis-empresas',
  ]
}
