NodeJs express.Router解析到錯誤的路徑

Question

我有如下路由器設置：

'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個父路由： parent

當我嘗試調用http://hostname/parent/subpath它會一直轉到http://hostname/parent/ 。 僅當我注釋掉以下subpath行時， subpath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;

我在做錯什么配置？

Answer 1

您需要顛倒路線的順序：

'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;

因為http://hostname/parent/subpath匹配/:param 。

Answer 2

嘗試將絕對路線放在相對路線之上。

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