推荐答案

你可以在亚历克斯·杨的Nodepad应用程序中找到您要尝试的内容的完整示例。你应该看看的2个重要文件是这些2：

https://github.com/alexyoung/nodepad/blob/master/app.js

You can find a complete sample of what you're trying to do in the Nodepad application by Alex Young. The 2 important file you should take a look at are these 2:

模型看起来像这样：

  User = new Schema({
    'email': { type: String, validate: [validatePresenceOf, 'an email is required'], index: { unique: true } },
    'hashed_password': String,
    'salt': String
  });

  User.virtual('id')
    .get(function() {
      return this._id.toHexString();
    });

  User.virtual('password')
    .set(function(password) {
      this._password = password;
      this.salt = this.makeSalt();
      this.hashed_password = this.encryptPassword(password);
    })
    .get(function() { return this._password; });

  User.method('authenticate', function(plainText) {
    return this.encryptPassword(plainText) === this.hashed_password;
  });

  User.method('makeSalt', function() {
    return Math.round((new Date().valueOf() * Math.random())) + '';
  });

  User.method('encryptPassword', function(password) {
    return crypto.createHmac('sha1', this.salt).update(password).digest('hex');
  });

  User.pre('save', function(next) {
    if (!validatePresenceOf(this.password)) {
      next(new Error('Invalid password'));
    } else {
      next();
    }
  });

我想他也在dailyjs网站上解释代码。
