Ruby和RSS2 Feed不显示图像

Question

尝试创建一个简单的RSS2 Feed，稍后将其传递给FeedBurner，但根本无法获得RSS feed来显示图像。

另外，从我所读的内容中可以看到xml.instruct！ 最上面的内容可能会导致IE抱怨它不是有效的供稿。 这是真的？

我的代码看起来像

xml.instruct!

xml.rss "version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/" do
 xml.channel do

   xml.title           "Store"
   xml.link            url_for :only_path => false, :controller => 'products'
   xml.description     "Store"
   xml.pubDate         @products.first.updated_at.rfc822 if @products.any?

   @products.each do |product|
     xml.item do
       xml.title       product.name
       xml.pubDate     (product.updated_at.rfc822)
       xml.image do
         xml.url       domain_host + product.product_image.url(:small)
         xml.title     "Store"
         xml.link      url_for :only_path => false, :controller => 'products'
       end
       xml.link        url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink
       xml.description product.fine_print
       xml.guid        url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink
     end
   end
 end

结束

Answer 1

您的图像路径是相对的还是包含资源的完整URI？ 仔细检查脚本编写的源代码是否有这种情况。 Google阅读器将尝试更正此问题，但并非每个RSS工具都会做到这一点。
