将Middleware应用于同一文件中其他路由中的特定下一连接路由

Question

我正在使用next-connect，并且只想将yup验证中间件应用于特定的路由(post)。包含路由的文件还包含其他路由(例如get、put)。有没有什么办法我可以只在我的post路由上应用yup验证中间件？或者这个文件只能包含我的post路由，而我的其他api路由，如get和put，将需要保存在另一个文件中？

下面是代码。感谢您的建议，谢谢

import nextConnect from "next-connect";
import bcrypt from "bcryptjs";

import middleware from "../../middlewares/middleware";
import yupValidator from "../../middlewares/yupValidator";
import { extractUser } from "../../lib/api-helpers";

const handler = nextConnect();

//! For Global Middlewares
handler.use(middleware);

handler
  .post(async (req, res) => {
    //! Apply yupValidator for this route only
    const { name, password } = req.body;
    console.log(name, body);
  })
  .get(async (req, res) => {
    //! Do not apply yupValidator for this route
    console.log(req);
  });

import nc from "next-connect";
import bcrypt from "bcryptjs";
import * as yup from "yup";

import middleware from "../../middlewares/middleware";
import yupValidator from "../../middlewares/yupValidator";
import { extractUser } from "../../lib/api-helpers";

const userSchema = yup.object().shape({
  name: yup.string().trim().required().min(3),
  password: yup.string().required().min(5, "must be more than 5 words la"),
});

const handler = nc();

//! For Global Middlewares
const base = nc().use(middleware);
//! Route Specific Middlewares
const validation = nc().post("/api/users", yupValidator(userSchema));

handler
  .use(base)
  .use(validation)
  .post(async (req, res) => {
    //! Apply yupValidator for this route only
    const { name, password } = req.body;
    console.log(name, password);
    res.status(201).send("Done");
  })
  .get(async (req, res) => {
    //! yupValidator not applied to this get route
    console.log(req);
  })
  .put(async (req, res) => {
    //! yupValidator not applied to this put route
    const { name, password } = req.body;
    console.log(name, password);
    res.status(201).send("Done");
  });

export default handler;
