简介

• 通过OAuth方式同步用户消息到微博平台（支持豆瓣，新浪微薄，腾讯微博，搜狐微博，网易微博）
• 和omini-auth的区别：omini-auth是专门提供oauth授权和获取用户信息的gem(比如用新浪微博帐号登陆这种需求)
• oauth_china是一个方便的同步信息到其他微博平台的gem（用来做像follow5.com或http://fanfou.com/settings/sync这样需求）

#config/routes.rb  match "syncs/:type/new" => "syncs#new", :as => :sync_new  match "syncs/:type/callback" => "syncs#callback", :as => :sync_callback    # encoding: UTF-8  class SyncsController < ApplicationController      def new      client = OauthChina::Sina.new      authorize_url = client.authorize_url      Rails.cache.write(build_oauth_token_key(client.name, client.oauth_token), client.dump)      redirect_to authorize_url    end      def callback      client = OauthChina::Sina.load(Rails.cache.read(build_oauth_token_key(params[:type], params[:oauth_token])))      client.authorize(:oauth_verifier => params[:oauth_verifier])        results = client.dump        if results[:access_token] && results[:access_token_secret]        #在这里把access token and access token secret存到db        #下次使用的时候:        #client = OauthChina::Sina.load(:access_token => "xx", :access_token_secret => "xxx")        #client.add_status("同步到新浪微薄..")        flash[:notice] = "授权成功！"      else        flash[:notice] = "授权失败!"      end      redirect_to root_path    end      private    def build_oauth_token_key(name, oauth_token)      [name, oauth_token].join("_")    end  end
