如何在轨道上使用带有红宝石的FB即时文章？
问题描述：
我有一个用红宝石制作的博客，它的文章很少。文章保存在数据库中。要写内容我使用Tinymce宝石。 rss正在Feedly上工作，我想展示关于FB即时文章的文章。我也跟着上FB页的文档： https://developers.facebook.com/docs/instant-articles/publishing/setup-rss-feed如何在轨道上使用带有红宝石的FB即时文章？
，并试图使其与在此两个链接中找到的信息工作： https://www.codingfish.com/blog/129-how-to-create-rss-feed-rails-4-3-steps
和
http://apidock.com/rails/Builder/XmlMarkup
有时FB就装好文章但风格不见了，找不到任何内容，找不到任何文章，然后我得到了“出错了......”的错误，不得不等待一段时间，等等。 我不知道该怎么做。这是feed.rss.builder的最后一个版本，FB不能看到任何东西（您还没有创建任何即时文章）。

xml.instruct! :xml, :version => "1.0"

xml.channel do
xml.title "Blog"
xml.author "Blog"
xml.description "Web Development"
xml.link "http://myblog.dev.eu/"

xml.item do

xml.head do
xml.link("rel" => "stylesheet", "title" => "default", "href" => "#")
xml.title(article.title)
xml.meta("property" => "fb:article_style", "content" => "bam")
xml.link("rel" => "canonical", "href" => "http://myblog.dev.eu/blog_posts/"+article.slug.to_s)
end
xml.body do
xml.header do
xml.image "http://myblog.dev.eu/" + article.picture_url.to_s
end
xml.article(article.content)
end
end
end
end
end
end
请帮我解决这段代码！我想提交它用于审查，并且不再触摸feed.rss.builder中的代码。谢谢！
编辑：
我已经在代码改变一些东西，现在看起来这样：
#encoding: UTF-8
xml.instruct! :xml, :version => "1.0"
xml.rss :version => "2.0", "xmlns:content"=>"http://purl.org/rss/1.0/modules/content/" do
xml.channel do
xml.title "MyBlog"
xml.link "http://myblog/"
xml.description "Web Development, Digital Marketing, Education"
xml.language "en-us"
xml.lastBuildDate Time.new.strftime("%Y-%-m-%dT%H:%M").to_s
for article in @blog_articles
xml.item do
xml.title article.title
xml.link "http://myblog.eu/"+article.slug.to_s
xml.guid article.id
xml.pubDate article.created_at.strftime("%Y-%-m-%dT%H:%M").to_s
xml.author article.author_name
xml.description article.short_description
xml.content:encoded do
xml.tag!("!doctype html")
xml.html("lang"=>"en", "prefix"=>"op:http://media.facebook.com/op#") do
xml.head do
xml.meta("charset"=>"utf-8")
xml.link("rel" => "stylesheet", "title" => "default", "href" => "#")
xml.title(article.title)
xml.link("rel" => "canonical", "href" => "http://myblog.eu/blog_posts/"+article.slug.to_s)
xml.meta("property" => "fb:article_style", "content" => "bam")
end
xml.body do
xml.article do
xml.header do
xml.figure("data-mode" => "aspect-fit") do
xml.img("src"=>"http://myblog.eu/blog_posts/#{article.picture.url}")
end
xml.h1 article.title
xml.h2 article.short_description
xml.h3("Introduction" , "class"=>"op-kicker")
xml.address "myadr"
xml.time(article.created_at.strftime("%B %dth %Y, %l:%M %p").to_s, "class" => "op-published", "dateTime" => article.created_at.strftime("%Y-%-m-%dT%H:%M").to_s)
xml.time(article.created_at.strftime("%B %dth %Y, %l:%M %p").to_s, "class" => "op-modified", "dateTime" => article.updated_at.strftime("%Y-%-m-%dT%H:%M").to_s)
end
xml.p article.content
xml.figure("data-feedback"=>"fb:likes, fb:comments") do
xml.img("src"=>"http://myblog.eu/blog_posts/#{article.picture.url}")
xml.figcaption do
xml.h1 "descript"
xml.cite "text"
end
end
xml.footer do
xml.small "Lab"
end
end
end
end
end
end
end
end
end
现在FB认识的文章，但我仍然有错误：“缺少的标志”。我加入FB风格的标志，它可以在网上找到：
xml.meta("property" => "fb:article_style", "content" => "bam")
当我打开FB编辑一篇文章的全部内容在文章标签头标记前加入。它看起来是这样的：
<html>
<body><article><p>!doctype html/>
...Content...
</p>
<header><time class="op-modified" datetime="2016-01-19T10:38:00-08:00">2016-01-19T10:38:00-08:00</time><time datetime="2016-01-19T10:38:00-08:00" class="op-published"></time><h1>Title</h1></header><footer></footer></article></body>
<head><link rel="canonical" href="http:///myblog.eu/article.title"></head>
</html>
而且它还没有准备好进行审查。有任何想法吗？
答
内容应包装在CDATA注释块中。
这就是我在Rails中所做的。
