Node.js Restful API無法發布

Question

我已經使用可在redis上運行的nodejs創建了一個REST API，我能夠使用get方法調用api，並且可以正常工作，但是當我將其更改為post並嘗試使用post調用時。 我收到錯誤消息Cannot POST 。 我在下面附加我的代碼，您能告訴我我在做什么錯嗎？

app.post('/foobar/:ticketid/:date/:from_time/:to_time/:seats', function(req, res) {
    var id = req.params.ticketid;
    var date = req.params.date;
    var seats = req.params.seats;
    var from_time = req.params.from_time;
    var to_time = req.params.to_time;
    var key = id + date;
    var result = {};

    client.exists(key, function(err, reply) {
        if (reply === 1) {
            //console.log("Key Found data from key: ");
            client.get(key, function(err, reply) {
                var output = JSON.parse(reply);
                var data = [];
                output.forEach(function(entry) {
                    var temp = {};
                    temp['from_time'] = entry["from_time"];
                    temp['to_time'] = entry["to_time"];
                    if ((entry["from_time"] == from_time) && (entry["to_time"] == to_time)) {

                        temp['vacancies'] = entry["vacancies"] - seats;
                    } else {
                        temp['vacancies'] = entry['vacancies'];
                    }
                    data = data.concat(temp);
                });
                client.set(key, JSON.stringify(data));


                result['response'] = 1;
                result['message'] = 'vacancies successfully updated!';
                res.json(result);
            });
        } else {
            result['response'] = 0;
            result['message'] = 'Invalid timeslot!';
            res.json(result);
        }
    });
});

我使用郵遞員和Rest easy插件打電話。 在url中，我放置http://xxx.xxx.xxx.xxx:8081/foobar/ ；在正文中，我放置鍵值對

郵遞員的代碼：

POST /foobar/ HTTP/1.1
Host: xxx.xxx.xxx.xxx:8081

Answer 1

如果要在正文中發布值，則無需在URL中列出它們。 只要確保您的標頭設置為"Content-Type": "application/json"

app.post('/foobar', function(req, res) {
    var id = req.body.ticketid;
    var date = req.body.date;
    var seats = req.body.seats;
    var from_time = req.body.from_time;
    var to_time = req.body.to_time;
    ....
}

Answer 2

這不是傳遞參數並獲取它的正確方法

試試這個

app.post('/foobar/ticket/:ticketid/date/:date/from_time/:from_time/to_time/:to_time/seats/:seats

並以這種方式從客戶端發布

/foobar/ticket/123/date/your date/from_time/your date/to_time/your time/seats/123234

像這樣得到它

使用req.params檢查所有參數

var id = req.params.ticketid;
var date = req.params.date;
var seats = req.params.seats;
var from_time = req.params.from_time;
var to_time = req.params.to_time;
var key = id + date;
