快递护照到app.use（路线）

我试图发送护照到app.use（'/ api'）（护照），但我似乎得到一个错误，当这样做。 我应该甚至把它发送到app.use（），或者我可以recuire（）它在profile.js文件？ 我是新来expression，并正在跟随如何实施passport.js教程。

Server.js

 var config = require('./config/config'); var logger = require('morgan'); var path = require('path'); var express = require('express'); var app = require('./backend/backend.app.js'); app.use(logger('dev')); app.use(express.static('../')); app.use(express.static(path.join(__dirname, './frontend'))); app.all('/*', function (req, res) { res.sendFile(path.join(__dirname, './frontend/index.html')); }); 

backend.app.js

 var express = require('express'); var app = express(); var passport = require('passport'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var session = require('express-session'); var config = require('../config/config'); var flash = require('connect-flash'); require('./models/user'); require('./lib/passport')(passport); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({extended:true})); app.use(cookieParser()); app.use(session({ secret: 'secret',resave: true, saveUninitialized: true })); app.use(passport.initialize()); app.use(passport.session()); app.use(flash()); require('./router/routes')(app, passport); module.exports = app; 

routes.js

 var profile = require('./routes/profile'); var isLoggedIn = function(req, res, next){ if(req.isAuthenticated()) return next(); res.redirect('/'); }; var ExpressRouter = function(app, passport){ app.use('/api', profile)(passport); }; module.exports = ExpressRouter; 

profile.js

 var express = require('express'); var router = express.Router(); var mongoose = require('mongoose'); var User = mongoose.model('User'); module.exports = function (passport){ router.post('/signup', passport.authenticate('local-signup', { successRedirect : '/', failureRedirect : '/signup', failureFlash : true })); return router; };

在你的情况下，你必须使用路由器对象作为第二个参数调用app.use。 所以，而不是

 app.use('/api', profile)(passport); 

你应该这样写在你的routes.js文件中：

 app.use('/api', profile(passport)); 

由于profile(passport)返回一个快速路由器对象。
