Nodejs全局对象不更新

Question

我使用 angularjs 前端和 nodejs 作为后端，我很困惑为什么我的callobj 没有按预期工作。

我的相关nodejs代码是：

var client = require('twilio')(accountSid, authToken);

var unirest = require('unirest');
var express = require("express");
var http = require('http');
var app = express();
var o2x = require('object-to-xml');
var qs = require('querystring');
app.use(express.static('dist'));

app.get("/", function (req,res) {
    res.render('index.html');
});

var callobj = {};

app.post("/call", function(req,res){
    callobj.user = req.user;
    callobj.phone = req.phone;
    callobj.song = req.song;
    callobj.mp3link = req.mp3link;
    console.log(req.body);
    console.log(callobj);
    res.send(200);
});

app.get("/call", function(req,res) {
    console.log(callobj);
    res.set("Content-Type", "text/xml");
    res.send(o2x({
        '?xml version="1.0" encoding="utf-8"?' : null,
        Response: {
                Play: callobj.mp3link
        }
    }));
});

angularjs代码为：

var app = angular.module('angularexpressApp', []);

app.controller('appController', function($scope, $http){
  $scope.user = 'Shawn';
  $scope.phone = '5197227689'
  $scope.song = 'Cant feel my face';
  $scope.mp3link = 'https://api.twilio.com/cowbell.mp3';
  $scope.mp3submit = function(){
    $http.post('/call', {user: $scope.user, phone: $scope.phone, song: $scope.song, mp3link: $scope.mp3link})
       .success(function(data){
           //what to do here
       })
       .error(function(data){
           console.log('Error: ' + data);
       });
     };
});

您似乎将callobj 分配给了错误的值。如果我没记错的话，它应该设置为req.body.<param>。请求的正文应包含您想要的参数。
