Angular NgRepeat嵌套Json数据

Question

我需要使用ng-repeat读取此json文件。这是一个嵌套的json文件。我需要显示带有其源名称的文章列表，其描述和URL代码如下：

这是我的控制人

$scope.showNews = function(){
    MainDash.getNews().then(function(data){
        $scope.newsData = data.articles;
    })
}

这是我的服务

     factory.getNews = function(){
    return $http.get('news.json');
}
