# Atom Syndication This module provides a class called [AtomFeed](# "werkzeug.contrib.atom.AtomFeed") which can beused to generate feeds in the Atom syndication format (see [**RFC 4287**](http://tools.ietf.org/html/rfc4287.html) [http://tools.ietf.org/html/rfc4287.html]). Example: ~~~ def atom_feed(request): feed = AtomFeed("My Blog", feed_url=request.url, url=request.host_url, subtitle="My example blog for a feed test.") for post in Post.query.limit(10).all(): feed.add(post.title, post.body, content_type='html', author=post.author, url=post.url, id=post.uid, updated=post.last_update, published=post.pub_date) return feed.get_response() ~~~ *class *werkzeug.contrib.atom.AtomFeed(*title=None*, *entries=None*, ***kwargs*) A helper class that creates Atom feeds. <table class="docutils field-list" frame="void" rules="none"><col class="field-name"/><col class="field-body"/><tbody valign="top"><tr class="field-odd field"><th class="field-name">参数:</th><td class="field-body"><ul class="first last simple"><li>title – the title of the feed.
