node.js - 路线 护照-本地

Question

我正在尝试使用 Passport-local 来限制对网站的访问。
为此，我使用login_app来运行passport-local，但这本身就是从主app.js调用的路由。当尝试在第二层(护照文件/路由)上路由时，我发现找到了我的代码，但内部的函数没有被调用。
这是我的login_app代码:

var express       = require('express');
var router        = express.Router();
var mongoose      = require ('mongoose');
var flash         = require('connect-flash');
var passport      = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var morgan        = require('morgan');
var cookieParser  = require('cookie-parser');
var bodyParser    = require('body-parser');
var session       = require('express-session');

let app = express();

// pass passport for configuration
require('./passport-files/passport')(passport); 

//For express application
app.use(morgan('dev'));
app.use(cookieParser()); // read cookies (needed for auth)
app.use(bodyParser()); // get information from html forms

//Initialize passport session
app.use(session({ secret: 'secret' })); // session secret
app.use(passport.initialize());
app.use(passport.session());
app.use(flash()); // use connect-flash for flash messages stored in session


// load our routes and pass in our app and fully configured passport
require('./passport-files/routes')(app, passport);

module.exports = router;

为了简化问题，我只将 paths.js 文件放在这里:

var express       = require('express');
var router        = express.Router();

let app = express();
module.exports = function (app, passport) {
//function views (app, passport) {

/* GET users listing. */
// HOME PAGE (with login links) ========
app.get('/', function(req, res) {
    res.render('login-welcome', {});
});

// LOGIN ===============================
// show the login form
app.get('/log-in', function(req, res) {
    res.render('login', { message: req.flash('loginMessage') }); 
});

// process the login form
app.post('/log-in', passport.authenticate('local-login', {
    successRedirect : '/admin', // redirect to the secure profile section
    failureRedirect : '/log-in', // redirect back to the signup page if there is an error
    failureFlash : true // allow flash messages
}));

// we will use route middleware to verify this (the isLoggedIn function)
app.get('/profile', isLoggedIn, function(req, res) {
    res.render('profile', {
        user : req.user // get the user out of session and pass to template
    });
});

app.get('/logout', function(req, res) {
    req.logout();
    res.redirect('/');
}); 
};

// route middleware to make sure a user is logged in
function isLoggedIn(req, res, next) {

// if user is authenticated in the session, carry on 
if (req.isAuthenticated())
    return next();

// if they aren't redirect them to the hosme page
res.redirect('/');   

};

我几乎使用 scotch.io ( https://scotch.io/tutorials/easy-node-authentication-setup-and-local ) 中的示例构建了这个，但是我无法让它以这种方式工作。如果我将路由直接写入login_app，即使身份验证仍然不起作用，它们也会被识别。

你们中有人知道如何解决这个问题吗？需要更多信息吗？

这可能是问题所在:在您的 login_app 模块中，您正在导出 router，但是您实际上尚未在 router 上定义任何路由，它们都是在 app 的新实例上定义的。

在一个文件中创建路由器并将其导出以在主 app.js 文件中使用的简单示例如下所示:

/** app.js */
var express = require('express');
var app = express();
var myRoutes = require('./routes');
app.use(myRoutes);
app.listen(3000);


/** routes.js */
// instaniate a new router, add routes/middleware on it, and export it
var router = require('express').Router();
// define your routes and middleware here
// router.use( ... )
module.exports = router;

我认为 scotch.io 教程正在使用的另一种模式是让路由文件导出一个函数，将主应用程序实例传递到其中。那么这两个文件将如下所示:

/** app.js */
var express = require('express');
var app = express();
require('./routes')(app); // pass your main `app` instance into the function
app.listen(3000);


/** routes.js */
module.export = function(app) {
  // define all your routes and middleware here directly on the `app` that gets passed in
  // app.use( ... )
}
