javascript - 无法在 Express 上的 NodeJS 服务器中发布参数 id

Question

我目前正在开发一个 Ionic 应用程序，并使用 Express 在 NodeJS 中编写服务器并将其托管在 Heroku 上。但是，它没有正确发布所需的路线。当我在 Chrome 上测试时出现此错误:

Failed to load resource: the server responded with a status of 404 (Not Found) https://[SERVER NAME].herokuapp.com/rooms//messages

服务器应该在/rooms/和/messages/之间发布 id 参数，但事实并非如此。这是服务器端代码:

     var messages = []; //make an array to hold messages
     var rooms = [];

     app.get('/rooms', function(req, res) {
        res.json(rooms);
    });

    app.get('/rooms/:id/', function(req, res){
        var room = rooms[req.params.id];
        res.json(room);
    });

    app.post('/rooms', function(req, res) {
        var newRoom = {
            timestamp: new Date()
            //username: req.body.username
        };
        rooms.push(newRoom);
        res.json(rooms);
        console.log(rooms);
    });



    app.get('/messages', function(req, res) {  //req = request, res = response
        res.json(messages);
    });

    app.get('/messages/:id', function(req,res) {
        var message = messages[req.params.id];
        res.json(message);
    });

    app.post('/messages', function(req,res){
        var newMessage = {
            message:req.body.message,
            username:req.body.username,
            timestamp: new Date()
        };

        messages.push(newMessage);
        res.json(messages);
    });

为什么它没有正确发布正确的路线？当我检查 Heroku 上的日志时，它似乎没有获取房间的 :id。谢谢。

我修好了!以下是正确的路由方法，有兴趣的 friend 可以引用一下:

app.get('/rooms', function(req, res) {  //req = request, res = response
        var user = users[req.params.id];
        var userRooms=[];

        res.json(rooms);
    });

    app.get('/rooms/:id', function(req,res) {
        var room = rooms[req.params.id];
        res.json(room);
    });

    app.post('/rooms', function(req,res){
        var newRoom = {
            name:req.body.name,
            id:rooms.length, 
            username:req.body.username,
            timestamp: new Date(), 
            messages: [],
            players: []
        };
        rooms.push(newRoom);
        res.json(rooms);
    });

    app.post('/rooms/:id/messages', function(req, res){
        var room = rooms[req.params.id];
        var newMessage = {
            username:req.body.username,
            timestamp: new Date(),
            message: req.body.message
        }
        room.messages.push(newMessage);
        res.json(room);
    });

    app.post('/rooms/:id/players', function(req, res){
        var room = rooms[req.params.id];
        var newPlayer = {
            timestamp: new Date(),
            player: req.body.username
        };
        room.players.push(newPlayer);
        res.json(room);
    });
