如何让用户登录？是否可以使用ExpressJS和Passport？

Question

我在node.js中有一个服务器,使用快递和护照与passport-local策略.

我有数据库中的用户和通过护照我能够对它们进行身份验证,不幸的是当第二个请求来自同一客户端时该req.isAuthenticated()方法返回false.request(req.user = undefined)中也没有用户.

我也检查过,当我进行身份验证时,虽然我从用户那里回来了,但passport.authenticate('local'...我还是没有req.user填充.如果我尝试手动设置它,它就不会传播以用于后续请求.

我不明白我做错了什么,这是我的代码.

server.js

var express = require('express'),
compass = require('node-compass'),
routes = require('./server/routes')
http = require('http'),
path = require('path'),
passport = require('passport'),
LocalStrategy = require('passport-local').Strategy,
Database = require('./server/repositories/database'),
Configuration = require('./server/config').Config,
crypto = require('crypto');

var app = express();

app.enable("jsonp callback");

passport.use(new LocalStrategy(
  function(email, password, done) {
    process.nextTick(function () {
      var userService = new UserService();
      userService.login(email, crypto.createHash('md5').update(password).digest("hex"), function(error, user) {
        if (error) done(error, user);
        else if (!user) return done(null, false, { message: 'wrong credentials'}); 
        return done(null, user);
      });
    });
  }
));

passport.serializeUser(function(user, done) {
  done(null, user._id);
});

passport.deserializeUser(function(id, done) {
  var userService = new UserService();
  userService.findById(id, function(err, user) {
    done(err, user);
  });
});

app.configure(function(){
  app.set('port', Configuration.Port);
  app.set('views', __dirname + '/app/views');
  app.set('view engine', 'ejs');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.cookieParser()); 
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(compass({
    project: path.join(__dirname, 'app'),
      sass: 'styles'
  }));
  app.use(express.session({ secret: 'keyboard cat' }));
  app.use(function(err, req, res, next){
    console.error(err.stack);
    res.send(500, 'Something broke!');
  });
  app.use(passport.initialize());
  app.use(passport.session());
  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'app')));
});

routes.configure(app);

Database.open(function() { 
  app.listen(Configuration.Port, function() {
    console.log("Express server listening on port " + Configuration.Port);
  });
});

routes.js

var Configuration = require('./config').Config;
var ApiResult = require('../model/apiResult').ApiResult;
var ApiErrorResult = require('../model/apiErrorResult').ApiErrorResult;
var ApiReturnCodes = require('../model/apiReturnCodes').ApiReturnCodes;
var passport = require('passport');

var usersController = require('./controllers/usersController');

exports.configure = function(app) {
  function ensureAuthenticated(req, res, next) {
    console.log(req.isAuthenticated());
    if (req.isAuthenticated()) { return next(); }
    else {res.send(new ApiErrorResult(ApiReturnCodes.NOT_LOGGED_IN, null));}
  }

  app.post('/login', function(req, res, next) {
    passport.authenticate('local', function(err, user, info) {
      if (err || !user) { console.log(info); res.send(new ApiErrorResult(ApiReturnCodes.ENTITY_NOT_FOUND, null)); }
      // If this function gets called, authentication was successful.
      // `req.user` contains the authenticated user
      else res.send(new ApiResult(user));
    })(req,res,next);
  });

  app.get('/anotherLink', ensureAuthenticated, function(req, res, next) {
    res.json({Code:0});
  });
}

当我在/anotherLink经过身份验证后点击链接时,我得到res.isAuthenticated()了错误.

此外,当我看到被叫req.session后,ensureAuthenticated我得到:

{ cookie: 
   { path: '/',
     _expires: null,
     originalMaxAge: null,
     httpOnly: true },
  passport: {} }

我缺少什么来保存用户通过身份验证的信息？在客户端,我使用Angular只使用没有参数的url进行简单的get.

如果我忘了在这里放东西告诉我,我会更新它.任何帮助将不胜感激.谢谢

Answer 1

所以我发现我的代码出了什么问题.

我的passport.deserializeUser方法使用了这个方法userService.findById

那称为存储库......就像这样:

userRepository.findUnique({"_id": id}, callback);

因为正确的通话id所产生的MongoDB需要是:

userRepository.findUnique({"_id": new ObjectID(id)}, callback);

我希望这可以节省一些时间给下一个有同样问题的人.

这一细节,该代码应该很好地工作的每个人都想要使用LocalStrategy的Passport框架.
