使用feedzirra解析文件或流式输入

Question

我必须动态地“解析”Rails的"request.body“，类似于：

  feed = Feedzirra::Feed.parse(request.body.read)
  feed.entries do |entry|
    entry.title      # => "Ruby Http Client Library Performance"
    entry.url        # => "http://www.pauldix.net/2009/01/ruby-http-client-library-performance.html"
    entry.author     # => "Paul Dix"
    entry.summary    # => "..."
    entry.content    # => "..."
    entry.published  # => Thu Jan 29 17:00:19 UTC 2009 # it's a Time object
    entry.categories # => ["...", "..."]
  end

有可能吗？应该类似于从文件中获取流输入或读取，你不这样认为吗？

Answer 1

..。代码是正确的，以及解析的方式，我遗漏的是“输出”;-)

添加"puts"，我就得到了这些值(当我把http POST放到"request.body“中时)：

feed = Feedzirra::Feed.parse(request.body.read)
  feed.entries.each do |entry|
    puts entry.title      # => "Ruby Http Client Library Performance"
    puts entry.url        # => "http://www.pauldix.net/2009/01/ruby-http-client-library-performance.html"
    puts entry.author     # => "Paul Dix"
    puts entry.summary    # => "..."
    puts entry.content    # => "..."
    puts entry.published  # => Thu Jan 29 17:00:19 UTC 2009 # it's a Time object
    puts entry.categories # => ["...", "..."]
  end
