方法:
就是你自己把RSS XML的格式拼凑好,输出.并设置HTTP Header ，标记content-type为application/XML,常见的代码:
#Post_controller::feed() def feed require "rss" articles = Article.find :all, :order => 'post_date DESC', :limit => 10 feed = RSS::Maker.make("2.0") do |maker| maker.channel.title = "Gang of Technology" maker.channel.description = "Gang of Technology site" maker.channel.link = "http://up-u.com" maker.items.do_sort = true articles.each do |article| item = maker.items.new_item item.link = "http://www.***.com/archives/#{article.id}" item.title = article.title item.date = article.post_date item.description = "" end end send_data feed.to_s, :type => "application/rss+xml", :disposition => 'inline' end
方法B: Rails Controller->Action 代码:
复制代码 代码如下:
#Post_controller::feed def feed @posts=Post.find :all,:limit=>”id desc” end erb模板: xml.instruct! xml.rss(”version”=>”2.0″, “xmlns:dc”=>”http://purl.org/dc/elements/1.1/”) do xml.channel do xml.title “renlu.xu 's blog” xml.link(url_for(:action=>”start”,:only_path=>false)) xml.description “My life My love” xml.language “zh_CN” xml.ttl 60 for event in @posts do xml.item do xml.title(event.title) xml.description(event.body) xml.pubDate(event.created_at.to_s(:rfc822)) xml.guid(event.id) xml.link(”http://…..#{event.id}”) end end end end“rails制作rss feed的代码分享”的内容就介绍到这里了，感谢大家的阅读。如果想了解更多行业相关的知识可以关注编程网网站，小编将为大家输出更多高质量的实用文章！
