Question

我想在我卑鄙的应用程序中将对象传递给控制器。我不太确定该怎么做。我正在使用中间件来检查用户是否是管理员。但是需要在控制器内获取当前用户。我目前正在使用Parse来获取登录用户，但是此操作始终返回null，有时还会带回admin用户帐户。（不可靠）

路由器

  const express = require('express')
const admin = require('../middlewares/admin')

const router = express.Router()


router.get('/', (req, res) => {
  if (req.session.isAdmin){
    res.redirect(req.baseUrl + '/places')
  } else {
    res.redirect(req.baseUrl + '/userplaces')
  }  
})

router.get('/userplaces', (req, res) => {
  res.render('userplaces', req.session.user)
})

router.get('/places', admin, (req, res) => {
  res.render('places')
})

控制器（这是我需要使用用户对象的地方）

'use strict';

angular.module('app')
  .controller('UserPlaceCtrl',
    function ($scope, $mdDialog, Toast, $translate, Place, Category, Auth) {

      // Pagination options
      $scope.rowOptions = [5, 25, 50];

      $scope.query = {
        canonical: '',
        limit: 5,
        page: 1,
        total: 0,
        isFeatured: null,
        status: null,
        category: null,
        date: null,
        user : Auth.getLoggedUser() // user user object here 
      };

身份验证服务（当前使用解析但未提供期望的结果）

    angular.module('app').factory('Auth', function ($q) {

      var mSessionToken = null;

      return {

        getLoggedUser: function () {
          return Parse.User.current();
        },
}
}

OR可以在这里在place服务中完成，并创建一个名为userplaces的方法。

angular.module('app').factory('Place', function ($q, moment) {

    var Place = Parse.Object.extend('Place', {
        initialize: function () {
            this.images = [];
        }
    }, {

            getInstance: function () {
                return this;
            },

            save: function (obj) {
                return obj.save();
            },

            delete: function (obj) {
                return obj.destroy();
            },
//create new method instead of all and add user query param
            all: function (params) {

                var query = new Parse.Query(this);

                if (params.canonical != '') {
                    query.contains('canonical', params.canonical);
                }

                if (params.category && params.category !== null) {
                    query.equalTo('category', params.category);
                }

                if (params.date && params.date !== null) {
                    var start = moment(params.date).startOf('day');
                    var end = moment(params.date).endOf('day');
                    query.greaterThanOrEqualTo('createdAt', start.toDate());
                    query.lessThanOrEqualTo('createdAt', end.toDate());
                }

                if (params.status && params.status !== null) {
                    query.equalTo('status', params.status);
                }

                if (params.isFeatured && params.isFeatured !== null) {
                    query.equalTo('isFeatured', params.isFeatured);
                }

                if (params.user) {
                    query.equalTo('user', params.user);
                }

                query.include('category')
                query.descending('createdAt');

                if (params && params.limit) {
                    query.limit(params.limit);
                }

                if (params && params.limit && params.page) {
                    query.skip((params.page * params.limit) - params.limit);
                }

                return query.find();
            },

Inside Server.js

app.use((req, res, next) => {
  res.locals.user = req.session.user
  res.locals.isAdmin = req.session.isAdmin
  res.locals.page = req.url.split('/').pop()
  res.locals.appId = process.env.APP_ID
  res.locals.appName = process.env.APP_NAME
  res.locals.serverUrl = process.env.PUBLIC_SERVER_URL
  res.locals.googleMapsApiKey = process.env.GOOGLE_MAPS_API_KEY
  next()
})
