如何在 nextjs 服务器中添加中间件

Question

I am trying to add a middleware in nextjs server like the below node express server uploadFile.single("")

app.post("/upload-excel", uploadFile.single('file'), async (req, res) => {

Here is the nextjs server code, where I need to add the uploadFile.single('file')

export default function handler(req: any, res: NextApiResponse<Data>) {
  });
}

Create a _middleware file and handle based on your specific routes :

export function middleware(request: NextRequest) {
  const myCase =
    request.nextUrl.pathname.startsWith('/upload-excel');
     

  if (myCase) {
    //handle here
  }

}
