javascript - 如何使用 ionic 框架显示 RSS feed 中的图像

Question

我刚刚学习 ionic 。你能帮我解决这个问题吗不知怎的，我无法在android中显示图片

我使用此 js 代码从 Rss feed 获取数据

.controller("feedCtrl", function($http, $scope){$scope.init = function(){
$http.get("http://ajax.googleapis.com/ajax/services/feed/load", { params: { "v": "1.0", "num":"100", "q": "http://www.bola.net/feed/" } })
.success(function(data) {
    $scope.rssTitle = data.responseData.feed.title;
    $scope.rssUrl = data.responseData.feed.feedUrl;
    $scope.rssSiteUrl = data.responseData.feed.link;
    $scope.entries = data.responseData.feed.entries;
//  $scope.author = data.responseData.feed.author;
//  $scope.descriptionin = data.responseData.feed.description;
    //$scope.publishedDate = data.responseData.feed.publishedDate;
    //$scope.content = data.responseData.feed.content;
    //$scope.categories = data.responseData.feed.categories;
})
.error(function(data) {
    console.log("ERROR: " + data);
});}  $scope.browse = function(v){
window.open(v, "_system", "location=yes")}});

在我看来，我使用这段代码，

 <ion-content class="padding" ng-controller="feedCtrl" ng-init="init()">
    <div class="list">
      <a class="item" ng-href="{{entry.link}}" ng-click="window.open(this.href, '_blank', 'location=no'); return false;" ng-repeat="entry in entries">
        <b>{{entry.title}}</b><br/>
        <b>{{entry.link}}</b><br/>
        <b>{{entry.author}}</b><br/>
        <b>{{entry.publishedDate}}</b><br/>
        <b>{{entry.contentSnippet}}</b><br/>
        <b>{{entry.content}}</b><br/>
        <span ng-bind-html="entry.contentSnippet"></span>
      </a>
    </div>
</ion-content>

Android页面中输入内容的结果是这样的，

<img src="http://cdn.klimg.com/****.net/library/upload/20/2016/07/175/jose-mourinho_30eb505.jpg" align="left" hspace="5" width="100"/>Pelatih Manchester United Jose Mourinho mengungkapkan pasukannya sudah siap untuk menjalani laga menghadapi Galatasaray yang akan berlangsung di Gothenburg, Swedia, pada hari Sabtu (30/7).]]>

但我想要的只是图像的链接，

http://cdn.klimg.com/****.net/library/upload/20/2016/07/175/jose-mourinho_30eb505.jpg

我怎样才能做到这一点？谢谢

所有 Rss feed 都不会提供图像，但一些新闻 channel (例如 CNN)会在索引 mediaGroups 中提供图像...

{{entry.mediaGroups[0].url }}

共有11张不同分辨率的图片...
