想知道如何将这些快速路由分离到自己的文件中

Question

想知道如何将这些快速路由分离到它们自己的文件中。我已经尝试了几种方法，我开始觉得我在猜测。我不想猜测我想对快递如何通过路线路由护照有一个深入的了解。

//const loginRoute = require('./modelroutes/')
module.exports = function(app, passport) {

// normal routes ===============================================================

    // show the home page (will also have our login links)
    app.get('/', function(req, res) {
        res.render('../public/views/index.ejs');
    });

    // PROFILE SECTION =========================
    app.get('/profile', isLoggedIn, function(req, res) {
        res.render('../public/views/profile.ejs', {
            user : req.user
        });
    });

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

// =============================================================================
// AUTHENTICATE (FIRST LOGIN) ==================================================
// =============================================================================

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

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

        // SIGNUP =================================
        // show the signup form
        app.get('/signup', function(req, res) {
            res.render('../public/views/signup.ejs', { message: req.flash('loginMessage') });
        });

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

        // send to facebook to do the authentication
        app.get('/auth/facebook', passport.authenticate('facebook', { scope : 'email' }));

        // handle the callback after facebook has authenticated the user
        app.get('/auth/facebook/callback',
            passport.authenticate('facebook', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));

    // twitter --------------------------------

        // send to twitter to do the authentication
        app.get('/auth/twitter', passport.authenticate('twitter', { scope : 'email' }));

        // handle the callback after twitter has authenticated the user
        app.get('/auth/twitter/callback',
            passport.authenticate('twitter', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));


    // google ---------------------------------

        // send to google to do the authentication
        app.get('/auth/google', passport.authenticate('google', { scope : ['profile', 'email'] }));

        // the callback after google has authenticated the user
        app.get('/auth/google/callback',
            passport.authenticate('google', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));

// =============================================================================
// AUTHORIZE (ALREADY LOGGED IN / CONNECTING OTHER SOCIAL ACCOUNT) =============
// =============================================================================

    // locally --------------------------------
        app.get('/connect/local', function(req, res) {
            res.render('../public/views/connect-local.ejs', { message: req.flash('loginMessage') });
        });
        app.post('/connect/local', passport.authenticate('local-signup', {
            successRedirect : '/profile', // redirect to the secure profile section
            failureRedirect : '/connect/local', // redirect back to the signup page if there is an error
            failureFlash : true // allow flash messages
        }));

    // facebook -------------------------------

        // send to facebook to do the authentication
        app.get('/connect/facebook', passport.authorize('facebook', { scope : 'email' }));

        // handle the callback after facebook has authorized the user
        app.get('/connect/facebook/callback',
            passport.authorize('facebook', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));

    // twitter --------------------------------

        // send to twitter to do the authentication
        app.get('/connect/twitter', passport.authorize('twitter', { scope : 'email' }));

        // handle the callback after twitter has authorized the user
        app.get('/connect/twitter/callback',
            passport.authorize('twitter', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));


    // google ---------------------------------

        // send to google to do the authentication
        app.get('/connect/google', passport.authorize('google', { scope : ['profile', 'email'] }));

        // the callback after google has authorized the user
        app.get('/connect/google/callback',
            passport.authorize('google', {
                successRedirect : '/profile',
                failureRedirect : '/'
            }));

// =============================================================================
// UNLINK ACCOUNTS =============================================================
// =============================================================================
// used to unlink accounts. for social accounts, just remove the token
// for local account, remove email and password
// user account will stay active in case they want to reconnect in the future

    // local -----------------------------------
    app.get('/unlink/local', function(req, res) {
        var user            = req.user;
        user.local.email    = undefined;
        user.local.password = undefined;
        user.save(function(err) {
            res.redirect('/profile');
        });
    });

    // facebook -------------------------------

    });


};

// route middleware to ensure user is logged in
function isLoggedIn(req, res, next) {
    if (req.isAuthenticated())
        return next();

    res.redirect('/');
}

如果有人可以帮我解释一下 express 是如何通过单独的目录在路由中路由护照的。

Answer 1

Express 中的路由是通过从左到右的一系列中间件函数来处理的。因此，passport.authenticate() 和 passport.authorize() 只需返回一个合适的中间件函数，该函数执行其业务逻辑并负责重定向。

如果您想将您的路线分布在多个文件上（比如一个用于 Google，一个用于 Facebook，一个用于本地注册），您可以这样做：

/* 
 * google.js.
 */

// return a function which given passport returns a function 
// which will actually install the relevant routes on a Express app
//
// the reason for the indirection is that 
// you might end up wanting to inject other middleware
// so keeping the deps separate makes it easier/safer 
// for callers to assume a uniform interface.
const installMyGoogleMiddleWare = passport => app => {
};

module.exports = installMyGoogleMiddleWare;

然后像这样使用它：

/*
 * app.js
 */
const passport = ...
const app = ...

const allRoutes = [
    require('google.js'), 
    require('facebook.js') /* ... */
].map(factory => factory(passport));

allRoutes.forEach(route => route(app));
