我想要做的就是將LinkedIn標題和組標題的標識存儲到我的文章模型中。這應該發生在：LinkedIn API JSON - 我做錯了什麼？
irb> Article.update_from_linkedin_group
我花了很多時間，並嘗試了很多變化。有人能找出我缺少的東西嗎？
article.rb（模型）：
class Article < ActiveRecord::Base
def self.update_from_linkedin_group
require 'linkedin'
client = Linkedin.new({
:consumer_key => "zzzzzz", # LinkedIn API key.
:consumer_secret => "zzzzzzz", # LinkedIn API secret.
:access_token => "zzzzzzz", # Authenticated user access token.
:access_secret => "zzzzzz" # Authenticated user access secret.
})
json = client.group
puts json.inspect
add_entries(json)
end
private
def self.add_entries(values)
values.each do |value|
unless exists? guid: value.id
create!(
title: value.title,
guid: value.id
)
end
end
end
end
關注/ linkedin.rb：
class Linkedin
require 'oauth'
require 'active_support'
require 'json'
def initialize(config)
consumer = OAuth::Consumer.new(config[:consumer_key], config[:consumer_secret], {
:site => 'https://api.linkedin.com',
:authorize_path => '/uas/oauth/authorize',
:request_token_path => '/uas/oauth/requestToken',
:access_token_path => '/uas/oauth/accessToken'
})
@client = OAuth::AccessToken.new(consumer, config[:access_token], config[:access_secret])
end
def group
request(:get, '/groups/4896676/posts?order=recency&category=discussion&format=json')
end
private
def request(method, path)
JSON.parse(@client.request(method, 'https://api.linkedin.com/v1' + path).body)
end
end
