解析文件或流输入与feedzirra

Question

我已经为“解析”一个Rails“request.body”在飞行中，是这样的：

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 

这可能吗？应该类似于获取流式输入或从文件中读取，你不这么认为吗？

Answer 1

...代码是正确的，以及解析的方式，我错过了“输出” ;-)

添加“看跌期权”，我得到在飞行中的值（而我“M越来越HTTP POST到 “request.body”）：

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
