聽說讀寫

public class ODataBaseService<T> : DataService<T>//, IServiceProvider
    {
        public ODataBaseService()
        {
            this.ProcessingPipeline.ProcessingRequest += new EventHandler<DataServiceProcessingPipelineEventArgs>(ProcessingPipeline_ProcessingRequest);
        }
        void ProcessingPipeline_ProcessingRequest(object sender, DataServiceProcessingPipelineEventArgs e)
        {
            if (Authenticate(HttpContext.Current))//在這里使用http header 或者其他的http request 內容來判斷用戶 和權限
                throw new DataServiceException(401, "401 Unauthorized");
        }
