Node.js 路由器解析到错误路径

我有如下路由器设置：

'use strict';

const express = require('express');
const controller = require('../../module/controllers/controller');

const router = express.Router();

router.get('/:param', controller.getEntity);
router.get('/', controller.getEntities);
router.put('/:param', controller.updateEntity);
router.post('/update/:param', controller.updateEntity);
router.get('/subpath', controller.getEntityPath);

module.exports = router;

以上所有路由都有一个父路由：

parent

当我尝试呼叫

http://hostname/parent/subpath

它会一直转到

http://hostname/parent/

。仅当我注释掉以下行时，

子路径

才可用：

'use strict';

const express = require('express');
const controller = require('../../module/controllers/controller');

const router = express.Router();

// router.get('/:param', controller.getEntity);
// router.get('/', controller.getEntities);
router.put('/:param', controller.updateEntity);
router.post('/update/:param', controller.updateEntity);
router.get('/subpath', controller.getEntityPath);

module.exports = router;

我在配置中做错了什么？

尝试将绝对路由置于相对路由之上

router.post('/update/:param', controller.updateEntity);
router.get('/subpath', controller.getEntityPath);    
router.put('/:param', controller.updateEntity);

尝试将绝对路线置于相对路线之上

router.post('/update/:param', controller.updateEntity);
router.get('/subpath', controller.getEntityPath);    
router.put('/:param', controller.updateEntity);

您需要颠倒路线的顺序：

'use strict';

const express = require('express');
const controller = require('../../module/controllers/controller');

const router = express.Router();

router.get('/', controller.getEntities);
router.post('/update/:param', controller.updateEntity);
router.get('/subpath', controller.getEntityPath);
router.get('/:param', controller.getEntity);
router.put('/:param', controller.updateEntity);
module.exports = router;

因为

http://hostname/parent/subpath

首先匹配

/：param

。
