如何将配置的护照对象传递到 Express4 中的路由模块？

Question

从 Express 4 开始，你不应该这样做

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

module.exports = function(app, passport) {
    // =====================================
    // FACEBOOK ROUTES =====================
    // =====================================
    // route for facebook authentication and login

    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 : '/'
        }));

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

相反，您应该使用express.Route() 函数和

var routes = require('./app/routes.js');
app.use('/', routes);

如何将配置好的护照传递到 Express 4 中的路由模块中？

Answer 1

function 导出仍可用于在模块之间传递 passport 引用。它只会创建 return 和 Router，而不是直接修改 app。

var express = require('express');

module.exports = function(passport) {
    var router = express.Router();

    router.get('/auth/facebook', passport.authenticate('facebook', { scope : 'email' }));

    // etc.

    return router;
};

然后，app 可以 use 使用：

var routes = require('./app/routes.js')(passport);
app.use('/', routes);
