Javascript express js中routes内的多个函数

嗨，我是ExpressJS的新手，我想在route中添加多个函数，请解释如何在route中添加多个函数，我在company.js中有2个函数，但我不知道如何导出它并将其添加到index.js中

index.js

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

// Rest API
require(path.join(__dirname, './', 'company'))(router);


// Homepage/Client 
router.get('/', function(req, res, next) {
  res.sendFile(path.join(__dirname, '../', 'client', 'index.html'));
});

module.exports = function(app, passport) {
    // set authentication routes
    require('./authentication.js')(app, passport);

    // set other routes
    app.use('/', router);
};

company.js

  var sockets = require('../utilities/socket'); 
  var authenticationMiddleware = 
  require('../middlewares/authentication.js');
  var companyModel = require('../models/company.js');

var getCompanyProfile = function(router){

  router.post('/api/v1/profile/fetchCompany', authenticationMiddleware.isLoggedIn, 
        function(req, res) {
            companyModel.getCompanyProfile(req['user'].id_user,
                                            function(result){
                                                return res.json(result);
                                            });
          }
    );

},
var saveCompanyProfile = function(router){

  router.post('/api/v1/profile/saveCompany', authenticationMiddleware.isLoggedIn, 
      function(req, res) {
        companyModel.saveCompanyProfile(req,
                        function(result){
                          return res.json(result);
                        });
      }
  );

}

module.exports = getCompanyProfile;

您可以按如下方式导出这两个函数

module.exports = {
   getCompanyProfile: getCompanyProfile,
   saveCompanyProfile: saveCompanyProfile 
}

并在index.js中导入，如下所示

const company = require('./company.js');
company.getCompanyProfile(router);
company.saveCompanyProfile(router);

---

引发错误，如router.post（'/api/v1/profile/getCompanyProfile'，authenticationMiddleware.isLoggedIn，^TypeError:无法读取未定义的属性'post'，您需要将路由器参数传递给那些函数，如

company.getCompanyProfile（路由器）

我刚刚给出了导出和导入导出函数的一般方法@veeran我只是忘记了根据您的问题编辑它..希望您有想法干杯
