一个控制器中的多个请求URL映射处理程序在Node Express JS中不起作用

在我的server.js文件中，我具有以下网址映射：

app.use('/registerCourse', require('./controllers/training.controller'));
app.use('/getCourses', require('./controllers/training.controller'));

在training.controller文件中，我已按照以下方式映射：

router.post('/registerCourse', registerCourse);
router.get('/getCourses', getCourses);

当呼叫"/registerCourse","/getCourses","/getCourseDetails"抛出错误时说：

“无法获取/getCourses”Server.js-

require('rootpath')();
var express = require('express');
var app = express();
var session = require('express-session');
var bodyParser = require('body-parser');
var expressJwt = require('express-jwt');
var config = require('config.json');

app.set('view engine', 'ejs');
app.set('views', __dirname + '/views');
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(session({ secret: config.secret, resave: false,    saveUninitialized: true }));


app.use('/login', require('./controllers/login.controller'));

app.use('/app', require('./controllers/app.controller'));

app.use('/registerCourse', require('./controllers/training.controller'));
app.use('/getCourses', require('./controllers/training.controller'));
app.use('/getCourseDetails', require('./controllers/training.controller'));



app.get('/', function (req, res) {
return res.redirect('/app');
});


var server = app.listen(3000, function () {
console.log('Server listening at http://' + server.address().address +    ':' + server.address().port);
});

training.controller.js-

var config = require('config.json');
var express = require('express');
var app = express();  
var router = express.Router();
var trainingService = require('services/training.service');
app.use(router);  

router.post('/registerCourse', registerCourse);
router.get('/getCourses', getCourses);
router.get('/getCourseDetails', getCourseDetails);
module.exports = router;


function registerCourse(req, res) {
   console.log(" registerCourse called ()"+req.body);
   trainingService.register(req.body);

}

function getCourses(req, res) {

     trainingService.getCourses()
    .then(function (data) {
        res.json(data);
    })
    .catch(function (err) {

        res.status(400).send(err);
    });
}
function getCourseDetails(req, res) {

    console.log(req.body)
}

解决方案：

您的路线将是：

/ register课程
/ getCourses
/ getCourseDetails

app.js

app.use('/login', require('./controllers/login.controller'));

app.use('/app', require('./controllers/app.controller'));
app.use('/',require('./controllers/training.controller'));

/* 
app.use('/registerCourse', require('./controllers/training.controller'));
app.use('/getCourses', require('./controllers/training.controller'));
app.use('/getCourseDetails', require('./controllers/training.controller'));
-- removed
*/

training.controller.js

var config = require('config.json');
var express = require('express');
// var app = express();  -- removed
var router = express.Router();
var trainingService = require('services/training.service');
// app.use(router);  -- removed

router.post('/registerCourse', registerCourse);
router.get('/getCourses', getCourses);
router.get('/getCourseDetails', getCourseDetails);
module.exports = router;


function registerCourse(req, res) {
   console.log(" registerCourse called ()"+req.body);
   trainingService.register(req.body);

}

function getCourses(req, res) {

     trainingService.getCourses()
    .then(function (data) {
        res.json(data);
    })
    .catch(function (err) {

        res.status(400).send(err);
    });
}
function getCourseDetails(req, res) {

    console.log(req.body)
}
