有没有办法解决这个问题？ 我的声音云控制器是这样的

class SoundcloudController < ApplicationController
  def connect
    redirect_to soundcloud_client.authorize_url(:display => "popup")
  end

  def connected
    if params[:error].nil?
      soundcloud_client.exchange_token(:code => params[:code])
      me = soundcloud_client.get("/me")

      login_as User.find_or_create_by_soundcloud_user_id({
        :soundcloud_user_id  => me.id,
        :soundcloud_username => me.username
      })

      current_user.update_attributes!({
        :soundcloud_access_token  => soundcloud_client.access_token,
        :soundcloud_refresh_token => soundcloud_client.refresh_token,
        :soundcloud_expires_at    => soundcloud_client.expires_at,
      })
    end
    render :layout => false
  end

  def disconnect
    login_as nil
    redirect_to root_path
  end

private

  def soundcloud_client
    return @soundcloud_client if @soundcloud_client
    @soundcloud_client = User.soundcloud_client(:redirect_uri  => soundcloud_connected_url)
  end


end

class SoundcloudController“popup”）
结束
def已连接
如果参数[：错误].nil？
soundcloud_client.exchange_令牌（：code=>params[：code]）
me=soundcloud\u client.get（“/me”）
以用户身份登录。通过用户id查找或创建({
：soundcloud\u user\u id=>me.id，
：soundcloud_username=>me.username
})
当前用户。更新属性！({
：soundcloud\u access\u token=>soundcloud\u client.access\u token，
：soundcloud\u refresh\u token=>soundcloud\u client.refresh\u token，
：soundcloud\u expires\u at=>soundcloud\u client.expires\u at，
})
结束
render:layout=>false
结束
def断开
登录为nil
将\重定向到根\路径
结束
私有的
def soundcloud_客户端
如果@soundcloud\u client返回@soundcloud\u client
@soundcloud\u client=User.soundcloud\u client（：重定向\u uri=>soundcloud\u连接的\u url）
结束
结束

如果您的代码与github上的代码相同，则问题出现在第9行

me = soundcloud_client.get('/me')

也许你有类似于

soundcloud\u客户端的东西。获取
？能否显示文件SoundCloud控制器的代码并检查此行是否正确
