Node.js Express app.use ('/ Route') in andere Route laufen?

Question

In meiner Anwendung, ich habe drei Routen, die

http://localhost:8080/search 
http://localhost:8080/user  
http://localhost:8080/shop 

sind ich schreibe Routen in getrennter Datei, in server.js (die Datei laufen im Terminal):

app.use('/', require('./app/routes/index')(app,io,mongoose)); 

im Index. js:

app.use('/search', require('./searchRouter')(router)); 
    app.use('/user', require('./user')(router,io,mongoose,app,express)); 
    app.use('/shop', require('./shop')(router,io,mongoose,app,express)); 

Sie alle haben eine Route wie:

router.route('/') 
.get(function(req, res) { 
     res.send('routerRestuarant'); 
    }) 

.post(function(req, res) { 
    res.send('routerRestuarant'); 
}) 

.put(function(req,res){ 
    res.json({ 
     msg:"new shop.js router" 
    }) 
}); 

Problem:

Wenn ich eine Anfrage an Route ‚/ shop‘ senden, fand ich die Antwort von ‚/ search‘ kommen und keine Antwort von ‚/ shop‘ kommen, wie man es beheben?

Über passieren die Mungo, App, Express- Variablen

Ein Teil meines Codes ist unten:

Index.js:

var express = require('express'); 
//var router = express.Router({ mergeParams: true }); 
var router = express.Router(); 
var routeInit = function (app,io,mongoose) { 
    //app.use('sessions', require('./sessions')(router)); 

    app.use('/test', require('./searchRouter')(router)); 
    app.use('/user', require('./user')(router,io,mongoose,app,express)); 
    app.use('/shop', require('./shop')(router,io,mongoose,app,express)); 
    return router; 
}; 

module.exports = routeInit; 

Shop.js:

var routeShop = function (router,io,mongoose,app,express) { 
var Shop = require('../models/Shop')(mongoose); 

router.route('/createDish') 
    .post(function(req, res) { 
     var dish = req.param('dish', null); 
     var shopName = req.param('shopName', null); 
     for (var i = 0; i < dish.length; i++) { 
      Shop.addDish(shopName, dish[i], function(err) { 
       if (null == err) 
        res.json({ 
         code: 200 
        }); 
      }) 
     } 
    }) 
    return router; 
}; 

module.exports = routeShop; 

In Shop.js brauche ich die Variable Mungo, um die Mong init oose Schema, wenn ich nicht die Variable Mungo hier passieren werde, die complier Fehler ist:

/Users/Documents/Dropbox/MScCS/fos/app/routes/shop.js:8 
var Shop = require('../models/Shop')(mongoose); 
            ^

ReferenceError: mongoose is not defined 
    at routeShop (/Users/liyan/Documents/Dropbox/MScCS/fos/food-ordering-by-zwy-liyan/food-ordering/app/routes/shop.js:8:38)

auf diese Weise versuchen:

in server.js:

// defining components to be accessible from route handlers 
app.use(function(req, res, next) { 
    req.components = { 
    io: io, 
    mongo: mongoose 
    }; 
    next(); 
}); 

app.use(require('./app/routes/index')); 

in index.js:

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

router.use('/search', require('./searchRouter')); 
router.use('/user', require('./user')); 
router.use('/shop', require('./shop')); 

module.exports = router; 

in Router-Dateien:

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

router.get('/', function(req, res) { 
    req.components.io.emit('message', {data: "I'm in restaurant"}); 
    res.send('routerRestuarant'); 
}); 

router.post('/', function(req, res) { 
    res.send('routerRestuarant'); 
}) 

router.put('/', function(req,res){ 
    res.json({ 
    msg:"new shop.js router" 
    }); 
}); 

module.exports = router;
