passport.js 抛出未知的身份验证策略“谷歌”

Question

我一直在关注 this 指南，但一直收到错误消息“未知身份验证策略 'google'”。我不知道发生了什么，我已经尝试搜索其他答案但收效甚微。任何帮助将不胜感激，谢谢！

错误：

Answer 1

在我看来，您根本没有调用require('./passport.js')(passport)（或任何路径），即。您没有配置护照。我的假设可能得到以下事实的进一步支持：如果您包含来自 passport.js 的代码，您会看到 SyntaxError: Unexpected token ;，因为删除参数和多余的东西，这就是您定义的：

passport.use(new GoogleStrategy({}, passport.serializeUser(function(user, done){});

passport.deserializeUser(function(id, done) { });

function(token, refreshToken, profile, done) { });

如果您要学习该教程，您应该查看定义基本应用程序的第一部分。在您的admin.js 中，在require('passport') 行之后添加require('./passport.js')(passport)

Answer 2

步骤 1- 在 passport.js 中包含护照包并删除 module.exports 并像在 admin.js 中编写代码一样编写代码

Step 2 - 在 admin.js 中包含这一行 require('./passport.js'); 包含所有软件包之后。

您的 passport.js 将如下所示 -

var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;

    var User = require('../models/users.js');
    var configAuth = require('./auth.js');
    var passport = require('passport');
    
      
        passport.use(new GoogleStrategy({
            clientID        : configAuth.googleAuth.clientID,
            clientSecret    : configAuth.googleAuth.clientSecret,
            callbackURL     : configAuth.googleAuth.callbackURL,
        }, 
        passport.serializeUser(function(user, done){
            done(null, user.id);
        });
    
        passport.deserializeUser(function(id, done) {
            User.findById(id, function(err, user) {
                done(err, user);
            });
        });
    
        function(token, refreshToken, profile, done) {
            process.nextTick(function() {
                User.findOne({ 'google.id' : profile.id}, function(err, user) {
                    if(err)
                        return done(err);
    
                    if(user) {
                        return done(null, user);
                    } else {
                        var newUser         = new User();
                        newUser.google.id = profile.id;
                        newUser.google.token = token;
                        newUser.google.name = profile.displayName;
                        newUser.ggoogle.email = profile.emails[0].value;
    
                        newUser.save(function(err){
                            if(err)
                                throw err;
                            return done(null, newUser);
                        });
                    }
                });
            });
        }));
    

您的 admin.js 将如下所示 -

(function() {
  var express, isLoggedIn, passport, router;

  express = require('express');

  passport = require('passport');
 **// include the your passport.js file path
  require('./passport.js');**

  router = express.Router();

  isLoggedIn = function(req, res, next) {
    if (req.isAuthenticated()) {
      return next();
    }
    res.redirect("/admin");
  };

  router.get('/', function(req, res) {
    return res.render('admin/admin_index.jade');
  });

  router.get('/editor', isLoggedIn, function(req, res) {
    return res.render('admin/admin_editor.jade');
  });

  router.get('/auth/google', passport.authenticate('google', {
    scope: ['profile', 'email']
  }));

  router.get('/auth/google/callback', passport.authenticate('google', {
    successRedirect: '/editor',
    failureRedirect: '/'
  }));

  module.exports = router;

}).call(this);
