Hi David,
The reason the code you supplied doesn't work in Service Portal is because it uses an iframe that has a src path using plain http instead of https. It looks like you got the code from rssfeedwidget.com. But I don't believe they use https. So, even changing the url in the src attribute to use https more than likely won't get that to work either.
An alternative could be to use the RestMessageV2 and XMLDocument2 methods (and of course html and css to style it the way you want) to bring in the feed to your widget I have put together a very basic poc. It will bring in the Krebs on Security feed. It could also handle others too with a little adjustment. Most rss feeds are pretty much standard containing elements like channel, title, items, links etc.
Try putting this code within a widget and placing the widget on a page:
HTML:
<div class="panel panel-primary" ng-repeat="feed in c.data.feeds">
<div class="panel-heading">
<h4>${{{ feed.channel.title }}} - {{ feed.channel.description }}</h4>
</div>
<div>
<div class="list-group">
<div ng-repeat="item in feed.channel.items | limitTo: (offset - feed.channel.items.length) as filtered" class="list-group-item">
<a ng-href="{{item.link}}" target="_blank"><h3>{{ item.title }}</h3></a>
<h5>Author: {{ item['dc:creator'] }}</h5>
<div class="item-content">{{ item.description }}</div>
</div>
</div>
</div>
</div>
-------------------------------
CSS:
.item-content img {
width: 30%;
height: 30%;
display: block;
}
.feed-btn:first-of-type {
margin-left: 5px;
}
.feed-btn {
font-size: 9px;
}
----------------------
Server Script:
(function() {
try {
var r = new sn_ws.RESTMessageV2();
r.setHttpMethod('GET');
r.setEndpoint('https://krebsonsecurity.com/feed/');
var response = r.execute();
var responseBody = response.getBody();
data.httpStatus = response.getStatusCode();
var xmlDoc = new XMLDocument2();
xmlDoc.parseXML(responseBody);
data.feeds = [];
var feed = {};
feed.channel = {};
var channel = xmlDoc.getNode('//channel');
var channelIter = channel.getChildNodeIterator();
var items = [];
while(channelIter.hasNext()){
var node = channelIter.next();
var nodeName = node.getNodeName();
var nodeContent = node.getTextContent();
if(nodeName != '#text' && nodeName != 'item')
feed.channel[nodeName] = nodeContent;
if(nodeName == 'item'){
var item = {};
var category = '';
var itemIter = node.getChildNodeIterator();
while(itemIter.hasNext()){
var itemNode = itemIter.next();
var itemName = itemNode.getNodeName();
var itemContent = itemNode.getTextContent();
if(itemName != '#text' && itemName != 'category')
item[itemName] = itemContent;
if(itemName == 'category'){
if(category.length > 0)
category += ','+itemContent;
else
category += itemContent;
}
}
item.categories = category.split(",");
items.push(item)
}
feed.channel.items = items;
}
data.feeds.push(feed);
}
catch(ex) {
var message = ex.getMessage();
}
})();
This should give you a good starting point.
I hope that helps.
