javascript - 在 Express 4 中设置 Passport 时找不到 404 错误

Question

我真的很难让 passport 在我的 Node.js 应用程序中工作。我尝试在我的 app.js 中重新排序我的要求，但我仍然无法让它工作。这是我得到的错误:

Not Found

404

这是我的代码:

app.js:

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
var flash    = require('connect-flash');
var passport = require('passport');
var session  = require('express-session');
var routes   = require('./routes/index');
var userRoutes   = require('./routes/user');
var adminRoutes   = require('./routes/admin');
var config = require('./config/index.js');
var MongoStore = require('connect-mongo')(session);

var app = express();

mongoose.Promise = global.Promise;
var db = mongoose.connect(config.dbUrl, config.dbOpts);

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(express.static(path.join(__dirname, 'public')));
app.use(cookieParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

var store = new MongoStore({
  mongooseConnection: db.connection
});

app.use(session({
  secret: config.sessionSecret,
  store: store,
  resave: true,
  saveUninitialized: true
}));

app.use(flash());
app.use(passport.initialize());
app.use(passport.session());
require('./config/passport')(passport);

app.use('/', routes);
app.use('/', userRoutes);
app.use('/admin', adminRoutes);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

mongoose.connection.on('open', function(){
  mongoose.connection.db.listCollections(function(error, names) {
    if (error) {
      throw new Error(error);
    } else {
      names.map(function(name) {
        console.log('found collection %s', name);
      });
    }
  });
});

mongoose.connection.on('error', function(error){
  throw new Error(error);
});

module.exports = app;

这是我的登录路径:

routes/user.js:

var express = require('express');
var User = require('../controllers/user');
var passport = require('passport');
var router = express.Router();

router.get('/', function(req, res, next) {
    res.send('respond with a resource');
});

router.post('/login', passport.authenticate('local',
  { successFlash: 'Success!',
    failureFlash : 'Login failed' }));

这是我处理我的passport身份验证策略的文件:

config/passport.js:

var LocalStrategy = require('passport-local').Strategy;
var User = require('../models/user').model;
var configAuth = require('./auth');

module.exports = function (passport) {
    passport.serializeUser(function (user, done) {
        done(null, user.id);
    });
    passport.deserializeUser(function (id, done) {
        User.findById(id, function (err, user) {
            done(err, user);
        });
    });
    passport.use('local', new LocalStrategy({
        usernameField : 'email',
        passwordField : 'password',
        passReqToCallback : true
    },
    function(req, email, password, done) {
        User.findOne({ email :  email }, function(err, user) {
            if (err) return done(err);
            if (!user)
                return done(null, false, req.flash('loginMessage', 'This email does not exist.'));
            if (!user.validPassword)
                return done(null, false, req.flash('loginMessage', 'Oops! The password entered is incorrect.'));
            return done(null, user);
        });
    }));
    passport.use(new FacebookStrategy({
        clientID: configAuth.facebookAuth.clientID,
        clientSecret: configAuth.facebookAuth.clientSecret,
        callbackURL: configAuth.facebookAuth.callbackURL,
        profileFields: ["emails", "displayName", "name"]
    }
}

我已经在同一个路由文件中尝试了其他路由，以确保 app.js 可以看到这些路由并且它们工作正常。只有这个没有。有人可以告诉我做错了什么吗？

Answer 1

问题出在路由选项 successFlash 和 failureFlash 中。 passport.authenticate() 函数需要不同的选项，这些选项必须完全按照这种方式使用，否则它们将不起作用。因此，当我替换选项以完全匹配文档时:

app.post('/login',
  passport.authenticate('local', { successRedirect: '/',
                                   failureRedirect: '/login',
                                   failureFlash: true })
);

或

 passport.authenticate('local', function(err, user, info) {
            if (err) return res.status(500).send();
            if (!user) return res.status(400).json({error:info.message});
            req.logIn(user, function(err) {
                if (err) return next(err);
                return res.status(200).json(info.message);
            });
        })(req, res, next);

它起作用了。还有其他调用函数的方法，它们在此处的文档中列出: http://passportjs.org/docs/authenticate
