Node.js req.params.locationid没有获取ID

我有以下带有特殊ID的网址:

http://localhost:3000/location/5733e37adcba0f6d5aa88cf5/review/new 

这是一个带有表单的页面,该表单将被填写并提交给api并保存在我的数据库中。我遇到的一个奇怪问题是在我的控制器中,

req.params.locationid 
由于某种原因,

正在返回undefined

这是我的控制器代码:

module.exports.doAddReview = function(req, res) {
    var requestOptions, path, locationid, postdata;
    locationid = req.params.locationid;
    console.log("\n>>>> " + req.params.locationid + " <<<<\n");
    path = "/api/locations/" + locationid + '/reviews';
    postdata = {
        author: req.body.name,
        rating: parseInt(req.body.rating, 10),
        reviewText: req.body.review
    };
    requestOptions = {
        url : apiOptions.server + path,
        method : "POST",
        json : postdata
    };
    request(requestOptions, function(err, response, body) {
        if (response.statusCode === 201) {
            res.redirect('/location/' + locationid);
        } else {
            _showError(req, res, response.statusCode);
        }
    });
};

任何想法为什么req.params.locationid在我的其他控制器中运行良好,但在这一个中它不是出于某种原因?我的路由器可能错了吗?

顺便说一下,表格如下:

action="", method="post", role="form"

和路由器:

/* Locations pages */
router.get('/', ctrlLocations.homelist);
router.get('/location/:locationid', ctrlLocations.locationInfo);
router.get('/location/:locationid/review/new', ctrlLocations.addReview);
router.post('/location/:locaitonid/review/new', ctrlLocations.doAddReview);

因为您在路由器文件中输入错误。

router.post('/location/:locationid/review/new', ctrlLocations.doAddReview);
