节点挂在猫鼬行动上

Question

所以我正在开发一个使用Mongoose和Node的应用程序。每当我尝试使用邮递员获取/api/users或发布/api/users/name/name/email/test时，它就会挂起。我已确认它已连接到数据库，app.listen()位于db.once('open')

内

这是我的model.js

'use strict'

var mongoose = require('mongoose');
var Schema   = mongoose.Schema;

const userSchema = new Schema({
  first_name : String,
  last_name  : String,
  email      : {
             type   : String,
             unique : true
  },
  password   : String,
  age        : String,
  address    : String,
  phoneNumber: String,
  gender     : String,
  preffered  : String,
  alerts     : Array
});


module.exports = mongoose.model('User', userSchema)

这是我的controller.js

const User = require('../models/user');

module.exports = {

  getAllUsers: (req, res) => {
    User.find({}, (err, user) => {
      if(err) {res.send(err)}
      console.log('test');
      res.status(200).json(user);
    });
  },

  createUser: (req, res) => {
    var newUser = new User();
    newUser.first_name = req.params.fn;
    newUser.last_name  = req.params.ln;
    newUser.email      = req.params.em;
    newUser.password   = req.params.pw;
    newUser.save((err, user) => {
      if(err){res.send(err)}
      console.log(newUser.first_name + ' Created');
      res.json(user);
      mongoose.connection.close();
    });
  },

  readUser: (req, res) => {
    User.findOne({_id: req.params.id}, (err, user) => {
      if(err){res.send(err)}
      res.json(user)
    });
  },

  updateUser: (req, res) => {
    User.findOneAndUpdate({_id: req.params.id}, req.body, {new: true}, (err, user) => {
      if(err){res.send(err)}
      res.json(user);
    });
  },

  removeUser: (req, res) => {
    User.remove({_id: req.params.id}, (err, user) => {
      if(err){res.send(err)}
      res.json("User was succesfully deleted");
    });
  }
}

这是我的routes.js

const express = require('express'),
      router  = express.Router(),
      apiController     = require('./controllers/api.controller'    ),
      mainController    = require('./controllers/main.controller'   ),
      profileController = require('./controllers/profile.controller'),
      adminController   = require('./controllers/admin.controller'  );

module.exports = router;

//Handled by apiController
router.get('/api/users', apiController.getAllUsers);
router.post('/api/:fn/:ln/:em/:pw/', apiController.createUser);

router.route('/api/:id')
      .get(apiController.readUser)
      .put(apiController.updateUser)
      .delete(apiController.removeUser);
