路由.js

var categories = require('../controllers/categories.server.controller');
module.exports = function(app) {
app.get('/',function(request,response){
        return response.send("Welcome");
    });
    app.route('/')
        .get(function(request, response) {
            return response.send('Rayees');
        });
        .post(categories.create);
    app.route('/:categoryId')
        .get(categories.read)
        .put(categories.update)
        .delete(categories.delete)
    app.param('categoryId', categories.categoryId)
};

app.js文件

'use strict'
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express(),
    mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/pressworld');
var category = require('./server/routes/category.server.routes')(app);
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: false
}));
app.use(cookieParser());
app.use('/api/category', category);

我收到此错误

使用express。路由器和返回路由器obj，并将其用于express中间件。

请修改您的routes.js并使用router.get、router.post而不是应用程序。

module.exports = function(app) {
    var express = require('express');
    var router = express.Router();

    router.get('/',function(request,response){
        return response.send("Welcome");
    });
    return router;
};
