Tumblr API with Ruby

Question

我是ruby的新手，目前正在構建一個需要從Tumblr博客中提取的rails應用程序。我已經在這裏閱讀了幾個問題，在線教程和Tumblr的API文檔，兩週後，我卡住了。

https://www.tumblr.com/docs/en/api/v2

我讓使用的tumblr電話在我的控制器

require 'json' 
require 'tumblr_client' 
client = Tumblr::Client.new :consumer_key => 'consumerkey' 
@post = client.posts 'crossfitinterchange.tumblr.com', :type => 'text', :limit => 1, :filter => 'html' 

那麼這是返回（一小段）

{"blog"=>{"title"=>"Today's Workout", "name"=>"crossfitinterchange", "posts"=>118, "url"=>"http://crossfitinterchange.tumblr.com/", "updated"=>1444971275, "description"=>"", "is_nsfw"=>false, "ask"=>false, "ask_page_title"=>"Ask me anything", "ask_anon"=>false, "share_likes"=>true, "likes"=>0}, "posts"=>[{"blog_name"=>"crossfitinterchange", "id"=>131266609424, "post_url"=>"http://crossfitinterchange.tumblr.com/post/131266609424/friday-oct-16th-wod", "slug"=>"friday-oct-16th-wod", "type"=>"text", "date"=>"2015-10-16 04:54:35 GMT", "timestamp"=>1444971275, "state"=>"published", "format"=>"html", "reblog_key"=>"OWmgAbMO", "tags"=>[], "short_url"=>"http://tmblr.co/ZE0_uk1wG6O4G", "recommended_source"=>nil, "recommended_color"=>nil, "highlighted"=>[], "note_count"=>0, "title"=>"Friday Oct 16th WOD", "body"=>"<p>[STRENGTH]</p>\n\n<p>5 x 3 Push Press to find 3RM</p>\n\n<p>* complete 5 ring rows after each set</p>\n\n<p><br/>\n[CONDITIONING]</p>\n\n<p>7 mins EMOM:</p>\n\n<p>5 sit ups<br/>\nME Thrusters (115/80#) for duration of round</p>\n\n<p><br/>\n- REST 2 mins -</p>\n\n<p><br/>\n2 mins AMRAP Box Jump Overs (24/20&quot;)</p>\n\n<p><br/>\nScore is total Thrusters + Box Jump Overs</p>", ... 

在我看來，我有

<% @post.each do |p| %> 
<%= p.title %> 
<%= p.body %> 
<% end %> 

我收到一個標題和正文未定義的錯誤。 我收到了通過API返回的JSON，現在我該如何獲取帖子的標題和正文？

Answer 1

您的@post對象包含JSON數據。所以，你不需要循環，即不需要在該對象上使用.each。

搶title和body從@post JSON對象，你應該做的：

title = @post['blog']['title'] 
body = @post['blog']['body']
