或者，您可以使用Next.js的Custom Server functionality，只需首先定义您的API路由，然后将expressApp.all('*', nextHandler)放在末尾，以便Next捕获您的API端点未捕获的所有内容。

const express = require('express');
const next = require('next');

const APIRouter = require('./routes');

const dev = process.env.NODE_ENV !== 'production';
const hostname = 'localhost';
const port = 3000;

const nextApp = next({dev, hostname, port});
const nextHandler = nextApp.getRequestHandler();

const expressApp = express();

nextApp.prepare().then(() => {
  expressApp.use(APIRouter());
  expressApp.all('*', nextHandler);
  expressApp.listen(port, () => {
    console.log(`App listening on port ${port}`);
  });
});
