api路由users/userId/{userId}需要修改为users/?id=abc

Question

API路由需要更改，因为我想将id作为参数。

const express = require("express");
const router = express.Router();
const authenticate = require("../middlewares/authenticate");
const authorizeRoles = require("../middlewares/authorizeRoles");
const users = require("../controllers/users");
const { SUPERUSER } = require("../constants/roles");
const userValidator = require("../middlewares/validators/user");
const { upload } = require("../utils/multer");
const { getUserBadges } = require("../controllers/badges");
router.post("/verify", authenticate, users.verifyUser);
router.get("/userId/:userId", users.getUserById);
router.patch("/self", authenticate, userValidator.updateUser, users.updateSelf);
router.get("/", authenticate, userValidator.getUsers, users.getUsers);
router.get("/self", authenticate, users.getSelfDetails);
router.get("/isUsernameAvailable/:username", authenticate, users.getUsernameAvailabilty);
router.get("/chaincode", authenticate, users.generateChaincode);
router.get("/:username", users.getUser);
router.get("/:userId/intro", authenticate, authorizeRoles([SUPERUSER]), users.getUserIntro);
router.put("/self/intro", authenticate, userValidator.validateJoinData, users.addUserIntro);
router.get("/:id/skills", users.getUserSkills);
router.get("/:id/badges", getUserBadges);
// upload.single('profile') -> multer inmemory storage of file for type multipart/form-data
router.post("/picture", authenticate, upload.single("profile"), users.postUserPicture);
router.patch("/profileURL", authenticate, userValidator.updateProfileURL, users.profileURL);
router.patch("/rejectDiff", authenticate, authorizeRoles([SUPERUSER]), users.rejectProfileDiff);
router.patch("/:userId", authenticate, authorizeRoles([SUPERUSER]), users.updateUser);
router.get("/suggestedUsers/:skillId", authenticate, authorizeRoles([SUPERUSER]), users.getSuggestedUsers);
module.exports = router;

api路由users/userId/{userId}需要修改为users/?id=abc，因为这不符合API设计规则。

Express不能基于查询字符串路由，因此您需要自定义中间件来决定根据请求调用哪些处理程序。

• /users->authenticate, userValidator.getUsers, users.getUsers
• /users?id=abc->users.getUserById
例如

router.get("/", (req, res, next) => {
if (req.query.id) {
// handle user ID request
req.params.userId = req.query.id; // so you don't need to change getUserById
return users.getUserById(req, res, next);
}

next(); // otherwise, forward to the remaining middleware
}, authenticate, userValidator.getUsers, users.getUsers);
