How to create single API for getallUsers and getUser?
问题
To create a single API that can handle both getting all users and a single user, you can use a route like this:
router.get('/:id?', async (req, res) => {if (req.params.id) {// Get a single user by IDconst user = await User.findById(req.params.id).select('-password');if (!user) {res.status(404).json({ message: 'User not found' });} else {res.status(200).json(user);}} else {// Get all usersconst userList = await User.find().select('-password');res.status(200).json(userList);}});
This route handles requests with or without an id parameter. If an id is provided, it retrieves a single user by ID. If not, it retrieves all users.

I have to create a single API to get all users and a single user. How can I create an API for this?
Currently, I had APIs like this.
To get All Users:
router.get(`/`, async (req, res) =>{const userList = await User.find().select('-password')if(!userList) {res.status(500).json({success: false})}res.send(userList);})
To get single User:
router.get('/:id' , async (req,res) =>{const user = await User.findById(req.params.id).select('-password')if(!user){res.status(500).json({message: 'The User with give id is not found'})}res.status(200).send(user)})
Now my requirement is that have to create a single API for above both APIs.
How can I solve this?

你可以告诉客户，如果他们需要所有用户，他们应该将"id"参数设为"all"。
router.get("/:id", async (req, res) => {if (req.params.id === "all") {const userList = await User.find().select("-password");if (!userList) {res.status(500).json({ success: false });}res.send(userList);} else {const user = await User.findById(req.params.id).select("-password");if (!user) {res.status(500).json({ message: "未找到给定id的用户" });}res.status(200).send(user);}});
英文:
You can say clients that they should send all as id if they require all the users.
router.get("/:id", async (req, res) => {if (req.params.id === "all") {const userList = await User.find().select("-password");if (!userList) {res.status(500).json({ success: false });}res.send(userList);} else {const user = await User.findById(req.params.id).select("-password");if (!user) {res.status(500).json({ message: "The User with give id is not found" });}res.status(200).send(user);}});

使用路由器
let router = express.Router();router.get('/:id', function (req, res, next) {console.log("Specific User Router Working");res.end();});router.get('/all', function (req, res, next) {console.log("All User Router Working");res.end();});app.use('/user', router);
英文:
Use a router
let router = express.Router();router.get('/:id', function (req, res, next) {console.log("Specific User Router Working");res.end();});router.get('/all', function (req, res, next) {console.log("All User Router Working");res.end();});app.use('/user',router);
