LocalStrategy不是构造函数
问题描述:
我正在使用passport.js对于身份验证,并尝试设置本地策略。然而,每当我运行我的代码时,我得到一个错误,说localStrategy
不是一个构造函数。LocalStrategy不是构造函数
代码:
// config/passport.js
// load all the things we need
var localStrategy = require('passport-local');
// load up the user model
var User = require('../app/models/user');
// expose this function to our app using module.exports
module.exports = function(passport) {
// =========================================================================
// passport session setup ==================================================
// =========================================================================
// required for persistent login sessions
// passport needs ability to serialize and unserialize users out of session
// used to serialize the user for the session
passport.serializeUser(function(user, done) {
done(null, user.id);
});
// used to deserialize the user
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
// =========================================================================
// LOCAL SIGNUP ============================================================
// =========================================================================
// we are using named strategies since we have one for login and one for signup
// by default, if there was no name, it would just be called 'local'
var authenticate = User.authenticate();
console.log(authenticate);
passport.use('local-signup', new localStrategy(authenticate));
};
当我运行应用程序,我得到:
TypeError: localStrategy is not a constructor

如果你看看这里 https://www.npmjs.com/package/passport-local 他们使用新LocalStrategy
。我还有另一个应用程序也使用它,它的工作原理= S
帮助?
答
你只是错过了包括战略的需要
变化
var localStrategy = require('passport-local');
到
var localStrategy = require('passport-local').Strategy
;

Javascript区分大小写。尝试'新的LocalStrategy(...)'(注意大写'L') – Dirk
