我有以下 Express.js 文件

var express = require('express');
var favicon = require('serve-favicon');
var morgan = require('morgan');
var compression = require('compression');
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
var cookieParser = require('cookie-parser');
var errorHandler = require('errorhandler');
var path = require('path');
var config = require('./environment');
var passport = require('passport');

module.exports = function(app) {
    var env = app.get('env');

    app.set('views', config.root + '/server/views');
    app.engine('html', require('ejs').renderFile);
    app.set('view engine', 'html');
    app.use(compression());
    app.use(bodyParser.urlencoded({
        extended: false
    }));
    app.use(bodyParser.json());
    app.use(methodOverride());
    app.use(cookieParser());
    app.use(passport.initialize());
    app.use(passport.session()); // passport session middleware 
    if ('production' === env) {
        app.use(favicon(path.join(config.root, 'public', 'favicon.ico')));
        app.use(express.static(path.join(config.root, 'public')));
        app.set('appPath', config.root + '/public');
        app.use(morgan('dev'));
    }

    if ('development' === env || 'test' === env) {
        app.use(require('connect-livereload')());
        app.use(express.static(path.join(config.root, '.tmp')));
        app.use(express.static(path.join(config.root, 'client')));
        app.set('appPath', 'client');
        app.use(morgan('dev'));
        app.use(errorHandler()); // Error handler - has to be last
    }
};

用户使用 Facebook 登录后，在我的控制器中尝试执行 req.user或req.session.passport.user获取undefined.

如何获取当前登录的用户？

当认证成功时req.user自动设置为用户

var express               = require("express"),
app                   = express(),
bodyParser            = require("body-parser"),
mongoose               = require("mongoose"),
passport              = require("passport"),
flash                 = require("connect-flash"),
localStrategy         = require("passport-local"),
User                  = require("./models/user"),
passportLocalMongoose = require("passport-local-mongoose")


app.use(require("express-session")({
secret: "demoapp",
resave: false,
saveUninitialized: false
}));

app.use(passport.initialize());
app.use(passport.session());

passport.use(new localStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

app.use(bodyParser.urlencoded({extended: true}));

app.set("view engine", "ejs")
app.use(express.static(__dirname + "/public"));
app.use(express.static(__dirname + "/dashboard"));

获取当前用户详细信息。您可以将 currentUser 设置为您自己的文本 

app.use(function(req,res,next){
  res.locals.currentUser = req.user;
  next();
})

如果您使用 ejs 在浏览器中显示用户配置文件

<p> <%= currentUser.username %> </p>
<p> <%= currentUser.country %> </p>

您需要定义身份验证策略并调用 passport.authenticate 来验证您的用户。请参阅护照指南中的示例
