ruby-on-rails - 如何在rails中使用omniauth对微博进行API调用？

Question

我的代码是，

 consumer = OAuth::Consumer.new(app_key, app_secret, { :site => "http://api.weibo.com", :scheme => :header })

 request_token = consumer.get_request_token

 token_hash = { :oauth_token => request_token.params['oauth_token'], :oauth_token_secret => request_token.params['oauth_token_secret'] }

 access_token = OAuth::AccessToken.from_hash(consumer, token_hash)

 feeds = access_token.request(:get, '/2/account/get_uid.json?source=app_key')

但是，我收到以下错误

 {"error":"token_rejected!","error_code":21317,"request":"/2/account/get_uid.json"} 

如何解决此错误？
