OAuth :: Unauthorized（403 Forbidden）dropbox-api

Question

我在此行的回调中未获取授权错误：

request_token.get_access_token（：oauth_verifier =＆gt; params [：oauth_token]）

下面的

是我的控制器代码：

def new
   consumer      = Dropbox::API::OAuth.consumer(:authorize)
   request_token = consumer.get_request_token
   @dropbox_auth = request_token.authorize_url(:oauth_callback => dropbox_callback_url)
end

回调：

def dropbox_callback
   consumer      = Dropbox::API::OAuth.consumer(:authorize)
   request_token = consumer.get_request_token
   request_token.get_access_token(:oauth_verifier => params[:oauth_token]) **here is the line where I am getting the error**

   client = Dropbox::API::Client.new :token => token, :secret => secret
end
