我得到这个错误，只有当我试图登录与正确的细节意味着不正确的用户名，这是明确抛出错误，但不是为了正确的凭证。它在SignUp上运行得很好。

Local.js代码：

   var passport = require('passport'),
   LocalStrategy = require('passport-local').Strategy,
   User = require('mongoose').model('User');

 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);
    });
  }));
  }

在我的user.js中，我添加了用于验证的方法。

  UserSchema.methods.hashPassword = function(password) {
  return crypto.pbkdf2Sync(password, this.salt, 10000,
  64).toString('base64');
  };
  UserSchema.methods.authenticate = function(password) {
  return this.password === this.hashPassword(password);
  };

您尚未定义身份验证方法。将其附加到您的架构：

var user= mongoose.Schema({ 
    username: 'string',
    password: 'string'
});
authSchema.methods.authenticate = function( pwd ) {
    return ( this.password === pwd );
};
