미들웨어

const { user } = require("../models");

module.exports = async (req, res, next) => {
  const { cookie } = req.headers;

  if (!authToken || authType !== "accessToken") {
    res.status(401).send({
      message: "로그인 후 이용가능합니다.",
    });
    return;
  }
  try {
    const { userId } = jwt.verify(
      authToken,
      "my-secrect-key" //secretkey
    );

    user.findByPk(userId).then((user) => {
      res.locals.user = user;
      next();
    });
  } catch (error) {

route(laundry.routes.js)에서 미들웨어 사용할 때

router.post(
  "/apply",
  upload.single("file"),
  authMiddleware,
  laundryController.createApply
);
router.get("/", authMiddleware, laundryController.getApplyById);

loginCheck.js

const jwt = require("jsonwebtoken");
const { user } = require("../models");

app.js에서 res.locals.user값에 따라 열리는 page 다르게 처리

// 마이 페이지
