我正试图让考拉与 Omniauth 合作。一个用户模型使用 Omniauth 登录 Facebook,我想使用 Koala 作为客户端来提取正在使用该应用程序的用户朋友列表。我似乎没有正确保存令牌:
控制器
@friends = Array.new
if current_user.token
graph = Koala::Facebook::GraphAPI.new(current_user.token)
@profile_image = graph.get_picture("me")
@fbprofile = graph.get_object("me")
@friends = graph.get_connections("me", "friends")
end
数据库架构
create_table "users", :force => true do |t|
t.string "provider"
t.string "uid"
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
t.string "token"
end
用户模型有
def self.create_with_omniauth(auth)
create! do |user|
user.provider = auth["provider"]
user.uid = auth["uid"]
user.name = auth["user_info"]["name"]
end
end
Koala.rb 初始化器有:
module Facebook
CONFIG = YAML.load_file(Rails.root.join("config/facebook.yml"))[Rails.env]
APP_ID = CONFIG['app_id']
SECRET = CONFIG['secret_key']
end
Koala::Facebook::OAuth.class_eval do
def initialize_with_default_settings(*args)
case args.size
when 0, 1
raise "application id and/or secret are not specified in the config" unless Facebook::APP_ID && Facebook::SECRET
initialize_without_default_settings(Facebook::APP_ID.to_s, Facebook::SECRET.to_s, args.first)
when 2, 3
initialize_without_default_settings(*args)
end
end
alias_method_chain :initialize, :default_settings
end
会话控制器具有:
def create
auth = request.env["omniauth.auth"]
user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth)
session[:user_id] = user.id
session['fb_auth'] = request.env['omniauth.auth']
session['fb_access_token'] = omniauth['credentials']['token']
session['fb_error'] = nil
redirect_to root_url
end
