从angularjs REST服务使用JSON对象

我有一个REST服务返回JSON用一个号码

I have a rest service returning JSON with one number

{"uptime":"44"}

在网址可供选择：

available under url:

http://localhost/uptime

和我想显示使用页面angularJS此值。

and I want to display this value on page using angularJS.

我写了一个资源，从这个休息URL数据：

I wrote a resource to get data from this rest url:

angular.module('utilService', ['ngResource']).
factory('UtilService', function($resource) {
    var UtilService = $resource('/uptime', { },
        {
            'get' : { method: 'GET', params: { format: '.json' } , isArray : false }
        }
    )


    UtilService.loadUptime = function(cb) {
        return UtilService.get();
    }

    return UtilService;
});

但是，当我使用它的控制器：

But when I use it in Controller:

angular.module('log', ['logService', 'utilService']);


function UptimeCtrl($scope, UtilService) {
    var time = UtilService.loadUptime();
    $scope.uptime = time;
}

我所有我的网页上看到的是{正常运行时间：44}

all I see on my page is {"uptime":"44"}

我想我需要提取/接收的对象转换成JSON并获得它的正常运行时间属性。但我想JSON.parse，time.uptime，时间['的正常运行时间']和没有成功。

I guess I need to extract/convert received object to JSON and get it 'uptime' property. but I tried JSON.parse, time.uptime, time['uptime'] and without success.

我要么做一些完全错误或遗漏这里的一些基本问题。

I am either doing something completely wrong or missing some basic issue here.
