Passport.js信号误码

Question

在尝试使用有效帐户登录时获取以下错误

    if(!user.authenticate(password)){
               ^
TypeError: undefined is not a function

下面是我的locals.js，它在身份验证期间被调用

module.exports = function(){
  passport.use(new LocalStrategy(function(username,password,done){
    User.findOne({
      username:username
    },function(err,user){
      if(err){
        return done(err);
      }
      if(!user){
        return done(null,false,{
          message:'Unknown User'
        });
      }
      if(!user.authenticate(password)){
        return done(null,false,{
          message:'Invalid password'
        });
      }

      return done(null,user);
    });
  }));
};

还有我的routes.js文件

module.exports = function(app){
  app.route('/signup')
    .get(users.renderSignup)
    .post(users.signup);

  app.route('/signin')
    .get(users.renderSignin)
    .post(passport.authenticate('local',{
      successRedirect: '/',
      failureRedirect: '/signin',
      failureFlash : true
    }));

  app.get('/signout',users.signout);
};

我的用户模型：

  var UserSchema = new Schema({
    firstName: String,
    lastName : String,
    email: {
      type: String,
      match: [/.+\@.+\..+/, "Please fill a valid e-mail address"]
    },
    username : {
      type: String,
      trim: true,
      required:'Username is required',
      unique : true
    },
    password : {
      type:String,
      validate:[
        function(password){
          return password && password.length>6;
        },'Password should be longer'
      ]
    },
    sale:{
      type:String
    },
    provider:{
      type:String,
      required:'Provider is required'
    },
    providerId:String,
    providerDate:{},
    created : {
      type : Date,
      default : Date.now
    }
  });

我很习惯这个错误意味着什么。如果您需要进一步的信息来调试这个问题，请告诉我。

Answer 1

看起来您的模式缺少一个名为实例法的authenticate()。这不是自动提供的东西，所以您需要自己实现它。

从您的代码来看，它可能很简单：

UserSchema.methods.authenticate = function(password) {
  return this.password === password;
};

Answer 2

你可以简单地：

 if(user.password !== password){
    return done(null,false,{
      message:'Invalid password'
    });
  }

用户模型没有authenticate方法。
