This is API provides a couple of functions for working with RSS feeds. It exists because we were having uptime issues with the Google Feeds API. It fetches feeds, caches them for a while to reduce stress on the source server, and provides a simple javascript function to fetch, format and display the feeds.
First, include the script:
<script src='//assets.euractiv.com/feeds/feeds-min.js'></script>Uncompressed:
<script src='//assets.euractiv.com/feeds/feeds.js'></script>Note: the script relies on jQuery being loaded first.
This creates a function window.VSAC.feeds. It accepts the
following parameters:
feed_url: the URL to the feed. Required. It must be one of
the whitelisted domains in http_allowed_domains or
http_allowed_url.callback: the callback to call with the fetched feed data.
Will receive the response object as the first parameter (see Endpoint,
below).count: the number of entries to fetch, 1 to 100. Will not
return more entries than are currently in the feed no matter how high
the number is. Optional, default 3. fields: the fields in each item to fetch, as an array.
Optional, default ['link','title'].strip_tags: strip HTML tags from the result on the server
side. Highly recommended, default true.Below you should see a list of the latest five links from feedforall.com's sample feed:
<script src="https://assets.euractiv.com/feeds/feeds-min.js"></script>
<div id='example-container'>
<p>Below you should see a list of the latest five links
from feedforall.com's sample feed:</p>
</div>
<script>(function () {
var feed_url = 'http://www.feedforall.com/sample.xml',
callback = function (links) {
console.log(links);
var ul = $('<ul />'), li, a, i;
for (i = 0; i < links.length; i += 1) {
li = $('<li />');
a = $('<a />');
a.attr('href', links[i].link);
a.text(links[i].title);
li.text(': ' + links[i].description);
li.prepend(a);
ul.append(li);
}
$('#example-container').append(ul);
},
fields = ['link', 'title', 'description'],
count = 5;
window.VSAC.feeds(feed_url, callback, count, fields);
}());</script>
The Full Content Feed Endpoint is a small API that replaces description
attribute of an RSS feed with the full content of the linked item. It works
by:
link attribute from each feed itemdescription attribute in the feed with the
scrapted content.This endpoint exists to facilitate the republishing of wire service articles. It is available at:
//assets.euractiv.com/feeds/full-content.phpIt has the following query parameters:
feed: the configured handle for the feed. Available
handles: guardian-environment, guardian-global-development, reuters.api_key: to prevent abuse and copyright issues, the full
content feed is hidden behind an API key, which must be specified here.
Check the config file for the key.You must be logged in to view this example.

The API end point is located at:
//assets.euractiv.com/feeds/feed.phpIt accepts the following query parameters:
feed: the URL to the feed. Required. It must be one of the
whitelisted domains in http_allowed_domains or
http_allowed_url.count: the number of entries to fetch, 1 to 100. Will not
return more entries than are currently in the feed no matter how high
the number is. Optional, default 3. fields: the fields in each item to fetch, as a comma
separated list. Optional, default 'link,title'.strip_tags: strip HTML tags from the returned results.
Optional, default true.$ curl https://assets.euractiv.com/feeds/feed.php?feed=http%3A%2F%2Fwww.feedforall.com%2Fsample.xml&count=5&fields=link%2Ctitle%2Ccomments;

The database that powers this API is currently using
13.3 MB.
Expired items were last cleaned from the cache 1 days ago. The database was last vacuumed 1 days ago.
To ensure that the database is regularly cleaned, make sure the following line is in your cron tab (adjusting the frequency to your needs):
/15 * * * wget -q -O - https://assets.euractiv.com/feeds/clean-cache.phpDriver: sqlite | Clean cache now.
Warning! It looks like the database isn't being cleaned regularly. Are you sure cron is configured?
Configuration is located in the file /config/feeds.php.
If you do not have the ability to modify this file, contact your
administrator to have options changed. The configuration file should
contain an array with the name $config containing the
following offsets:
| Name | Type | Description | Current Setting |
|---|---|---|---|
full_content_feeds | array | The feeds to convert into full content. Format is an array of arrays,
where each entry contains the offsets:
| Login to view this setting |
callmap_driver | string | The callmap driver to use, either "sqlite", "fsstore" or "noop" | noop |
callmap_labels | array | Labels for the callmap, where the key is the regular expression to match and the value is the label to use | Login to view this setting |
callmap_visualize_default | array | Nodes to visualize by default | Login to view this setting |
callmap_probability | integer | Probability that a given hit will log. Important for high traffic sites. Set higher for lower probability. | 1000 |
cal_ttl | integer | The time, in seconds, to cache items before revalidating | 3600 |
cal_driver | string | The cache driver to use, either "fs" or "sqlite" or "noop" | sqlite |
http_allowed_domains | array | Allowed domains for fetching assets or generating URLs | Login to view this setting |
http_allowed_urls | array | Specified URLs or regular expressions of specified URLs match for fetching assets or generating URLs | Login to view this setting |
http_connect_timeout | integer | The amount of time, in seconds, that cURL should wait before returning an error status. 15 is a good value for most cases. | 15 |
api_key | string | The key to access protected API calls. This key should only be used in server-to-server communication to avoid exposing it to the broader internet. In requests, the key can be set in the query as the "api_key" value (eg http://example.com?api_key=keyboard_cat), in a POST request body as the "api_key" value, or as a header with the name "X-Vsac-Api-Key". | Login to view this setting |
