无法在ExpressJet上的NodeJS服务器上发布参数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，它不能正确发布所需的路线。我得到这个错误，当我测试它在Chrome：

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

服务器应张贴ID参数/间之间/和/消息/，但事实并非如此。以下是服务器端代码：

 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); 
    }); 

为什么不正确发布正确的路由？当我检查Heroku上的日志时，它看起来并没有得到房间的ID： 谢谢。

我修好了！ 下面是那些有兴趣谁正确的路由方法：

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); 
    });

我INIT表达与代码服务器：

var express = require('express'); 
var app = express(); 

app.get('/rooms/:id/messages', function (req, res) { 
    var id = req.params.id; 
    res.send('Hello, moto! ' + id); 
}); 

app.listen(2345, function() { 
console.log('server started'); 
}); 

当我浏览到http://localhost:2345/rooms/123/messages我在看页面字符串Hello, moto! 123

尝试删除您的其他路由进行测试，也许它是得到一些冲突。
