你可以写一个中间件。在next13中，中间件文件与package.json在同一个目录中，它应该是middleware.js（或.ts）。

export async function middleware(req: NextRequest, res: NextResponse) {
  // get all the cookies
  let cookies = req.cookies.getAll();
  // read those cookies. based on cookies you decide which paths can be visited
  const isAuthorized="define logic if the the user authorized"
  console.log("req.pathname", req.nextUrl.pathname);
  const currentPath = req.nextUrl.pathname;
  if (currentPath==="/dashboard" && isAuthorized ){
    // you allow the user to visit this page
    return NextResponse.next()
  }
  // similarly add logic for other cases 
}
