Javascript 无法分开快车4.13.1路线？

用NodeJS编写我的第一个应用程序。我有一个MongoDB和两个模式“blurbs”和“users”。我希望能够通过localhost/api/blurbs和localhost/api/users设置api。但是，两个URL都返回“blurbs”的信息。非常感谢您的帮助。这是我的代码：

/models/db.js：

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

// Connect to the database
var dbURI = 'mongodb:/\/localhost/scuba-noodle';
mongoose.connect(dbURI);

// Creating the user schema
var UserSchema = new Schema({
  "firstName": String,
  "lastName": String,
  "userId": String,
  "avatar": Buffer,
  "email": { type: String, unique: true },
  "created": {type: Date, default: Date.now },
  "loggedIn": Boolean,
  "lastLogin": Date,
  "noOfBlurbs": Number,
  "blurbs": [null],
  "votedOnBlurbs": [null],
  "rating": Number
});

// Exporting the user schema
module.exports = mongoose.model('User', UserSchema);

// Creating the blurb schema
var BlurbSchema = new Schema ({
  "author": String,
  "submitted": Date,
  "votes": Number,
  "trunk": String,
  "text": String
});

// Exporting the blurb schema
module.exports = mongoose.model('Blurb', BlurbSchema);

// Disconnect from the DB on App termination
process.on('SIGINT', function() {
  mongoose.connection.close(function() {
    console.log("Mongoose disconnected through app termination");
    process.exit(0);  
  });
});

/routes/user.js：

var express = require('express'),
  mongoose = require('mongoose'),
  router = express.Router(),
  User = require('../models/db');

router.use(function(req, res, next) {
  console.log("Incoming request...");
  next();
});

router.route('/')
  // POST
  .post(function(req, res){
    var user = new User();
    user.firstName = req.body.firstName;
    user.lastName = req.body.lastName;
    user.userName = req.body.userName;
    user.avatar = req.body.avatar || null;
    user.email = req.body.email;
    user.created = Date.now();
    user.loggedIn = false;
    user.lastLogin = Date.now();
    user.noOfBlurbs = 0;
    user.blurbs = [null];
    user.votedOnBlurbs = [null];
    user.rating = 0;

    user.save(function (err) {
      if (err) { res.send(err); }
          res.json({ message: "User created" });
        });  
      })
  // GET all
  .get(function(req, res) {
    User.find(function(err, users) {
      if (err) { res.send(err); }
      res.json(users);
   });
  });

router.route('/:user_id')
  //GET by ID
  .get(function(req, res) {
    User.findById(req.params.user_id, function(err, user) {
      if (err) { res.send(err); }
      res.json(user);
    });
  })
  //PUT by ID
  .put(function(req, res) {
    User.findById(req.params.user_id, function(err, user) {
      if (err) { res.send(err); }
      user.firstName = req.body.firstName || user.firstName;  
      user.lastName = req.body.lastName || user.lastName;
      user.userName = req.body.userName || user.userName;
      user.avatar = req.body.avatar || user.avatar;
      user.email = req.body.email || user.email;

      user.save(function(err, user) {
        if (err) { res.send(err); }
        res.json({ message: "User update" });
      });
    });
  })
  // DELETE by ID
  .delete(function(req, res) {
    User.remove({
      _id: req.params.user_id
    }, function(err, user) {
      if (err) { res.send(err); }
      res.json({ message: "Successfully Deleted" });
    });
  });

var userRouter = router;
module.exports = userRouter;

/routes/blurb.js：

var express = require('express');
var mongoose = require('mongoose');

var router = express.Router();
var Blurb = require('../models/db');

router.use(function(req, res, next) {
  console.log("Incoming request...");
  next();
});

router.route('/')
  // POST
  .post(function(req, res) {
    var blurb = new Blurb();
    blurb.author = req.body.author || "Anonymous";
    blurb.submitted = Date.now();
    blurb.votes = 0;
    blurb.trunk = req.body.trunk || "Unspecified";
    blurb.text = req.body.text || "Empty";

    blurb.save(function (err) {
      if(err) { res.send("Save Error: " + err); }
      res.json({ message: "Blurb Created" });
    });
  })
  // GET all
  .get(function(req, res) {
    Blurb.find(function(err, blurbs) {
      if (err) { res.send(err); }
      res.json(blurbs);
    });
  });

router.route('/:blurb_id')
  // GET by ID
  .get(function(req, res) {
    Blurb.findById(req.params.blurb_id, function(err, blurb) {
      if (err) { res.send(err); }
      res.json(blurb);
    });
  })
  // PUT by ID
  .put(function(req, res){
    Blurb.findById(req.params.blurb_id, function(err, blurb){
      if (err) { res.send(err); }
      blurb.author = req.body.author || blurb.author;
      blurb.submittee = Date.now();
      blurb.votes = blurb.votes;
      blurb.trunk = req.body.trunk || blurb.trunk;
      blurb.text = req.body.text || blurb.text;

      blurb.save(function(err) {
        if (err) { res.send(err); }
        res.json({ message: 'Blurb Updated' });
      });
    });
  })
  // DELETE by ID
  .delete(function(req, res) {
    Blurb.remove({
      _id: req.params.blurb_id
    }, function(err, blurb) {
      if (err) { res.send(err); }
      res.json({ message: 'Successfully Deleted' });
    });
  });

var blurbRouter = router;
module.exports = blurbRouter;

最后，server.js：

// Call packages
var express = require('express'),
  bodyParser = require('body-parser'),
  mongoose = require('mongoose');

// Create the server
var app = express();

// Configure bodyParser
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

// Setting the port
var port = process.env.PORT || 8080;

// Registering the routes
app.use('/api/blurbs', require('./routes/blurb'));
app.use('/api/users', require('./routes/user'));

// Starting the server
app.listen(port);
console.log('Nodejs Server Listening on port ' + port);

如果你有任何想法或建议，我真的很感激

原因是您正在覆盖

db.js

中的

模块.exports

：

module.exports = mongoose.model('User', UserSchema);

// ...

module.exports = mongoose.model('Blurb', BlurbSchema);

因此，由于后者是最后一个任务，

db.js

将导出

Blurb

模型。您可能应该改为执行以下操作：

exports.User = mongoose.model('User', UserSchema);
exports.Blurb = mongoose.model('Blurb', BlurbSchema);

并适当更改路由文件：

var User = require('../models/db').User;

及

@灵感来源-4.13.1版，效果不错！非常感谢你的帮助，我现在明白问题了。

var Blurb = require('../models/db').Blurb;
