Question

我正在创建一个简单的节点表达应用程序，我正在制作注册功能。我从我的索引路由调用createUser，它在我的用户模型中调用该函数，然后密码被加密和存储。但是当它从索引路由调用createUser函数时，它会给出上述错误。我无法弄清楚问题是什么!!

这是我的索引路径文件

    var express = require('express');
    var router = express.Router();
    var User = require('../models/User.js');


    /* GET home page. */
    router.get('/', function(req, res, next) {
    res.render('index', { title: 'Express' });
}); 


router.post('/login', function(req, res, next){

    var username = req.body.username;
    var password = req.body.password;

    User.getUserByUsername(username, function(err, user){
            if(err) throw err;

            if(!user){
                return res.send({msg: 'no user was found with this username'});
            }

            User.checkPassword(user, password, function(err, result){
                if (err) {
                    throw err;
                    return null;
                }
                if(user){
                    res.send({msg:'You are now logged in'});
                }else{
                    res.send({msg: 'Your password is wrong'});
                }

            })
    });

});

router.post('/signup', function(req, res, next){
var username = req.body.username;
var password = req.body.password;
var password2 = req.body.password2;
console.log(req.body);

req.checkBody('username', 'username field is required').notEmpty();
req.checkBody('password', 'password field is required').notEmpty();
req.checkBody('password2', 'confirm password field is required').notEmpty();

var errors = req.validationErrors();

console.log(errors);
if(errors){
    req.flash('error', 'there was some error with the signup process');
    res.send('there was some validation error');
}else{
    var newUser = new User({    
        username: username,
        password:password
    });
    console.log(newUser);
    User.createUser(newUser, function(err, user){
        if (err) throw err;
        console.log(user);
        res.send('user was created');
    })
}

  });

module.exports = router;

这是我的模型和架构

        var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/quizapp');
var db = mongoose.connection;
var bcrypt = require('bcrypt');

var UserSchema = mongoose.Schema({
    username:{
        type:String,
        required: true
    },
    password:{
        type:String,
        required:true,
        bcrypt:true
    }
});

module.exports.getUserByUsername = function(username, callback){
    User.findOne({username:username}, callback);
}
module.exports.checkPassword = function(pass, callback){
    callback(null, true);
}

module.exports.createUser = function (newUser, callback) {
    bcrypt.hash(newUser.password, 10, function(err, hash){
        if(err) throw err;
        newUser.password = hash;
        User.save(newUser, callback);
    });

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

首先，使用

将函数createUser附加到module.exports

module.exports.createUser = function (newUser, callback) {
    bcrypt.hash(newUser.password, 10, function(err, hash){
        if(err) throw err;
        newUser.password = hash;
        User.save(newUser, callback);
    });

};

然后你用

覆盖module.exports

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

所以现在module.exports只包含最后一次分配的值。

尝试这样做，

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

TypeError：User.createUser不是函数，在index.js 62：8
