Question

我使用angular $ http来调用webservice，但我无法从服务中获取任何数据，状态始终为0，

var httpurl = "http://127.0.0.1:3000?orderCode=700501898";


var myApp = angular.module('piechart', []);


myApp.factory('MyService', ['$http', function ($http) {
    return new function () {

        this.GetName = function () {
            return $http({
                url: httpurl,
                method:'GET'
            })
        };
    };
}]);
   angular.injector(['ng', 'piechart']).invoke(function (MyService) {

    MyService.GetName();

});

为什么要将$http服务封装两次？

var httpurl = "http://127.0.0.1:3000?orderCode=700501898";


var myApp = angular.module('piechart', []);


myApp.factory('MyService', ['$http', function ($http) {
    return {

        GetName:function () {
            return $http({
                url: httpurl,
                method:'GET'
            })
        }
    };
}]);

   angular.injector(['ng', 'piechart']).invoke(function (MyService) {

    MyService.GetName();

});

angular $ http总是返回状态0
