Question

我正在使用 passport.js 进行身份验证，并尝试设置本地策略。但是，每当我运行我的代码时，我都会收到错误消息，指出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));


};

当我运行应用程序时，我得到：

TypeError: localStrategy is not a constructor
    at module.exports (/home/ubuntu/workspace/config/passport.js:38:35)
    at Object.<anonymous> (/home/ubuntu/workspace/server.js:19:29)

    at run (bootstrap_node.js:389:7)
    at startup (bootstrap_node.js:149:9)
    at bootstrap_node.js:504:3

如果你看这里 https://www.npmjs.com/package/passport-local 他们确实使用新的LocalStrategy。而且我有另一个使用它的应用程序，它的工作原理= S

帮助？

您错过了在您的要求中包含策略

更改

var localStrategy = require('passport-local');

到

var localStrategy = require('passport-local').Strategy;

LocalStrategy不是构造函数
