Orchard源码分析（5.3）：EndRequest事件处理（DefaultOrchardHost.EndRequest方法）

EndRequest事件处理的作用是处理完"处理引擎(ProcessingEngine)"中的任务(Task)。

 

        void IOrchardHost .EndRequest() {

            Logger.Debug( "EndRequest");

            EndRequest();

        }

  

         protected virtual void EndRequest() {

            // Synchronously process all pending tasks. It's safe to do this at this point

            // of the pipeline, as the request transaction has been closed, so creating a new

            // environment and transaction for these tasks will behave as expected.)

            while (_processingEngine.AreTasksPending()) {

                _processingEngine.ExecuteNextTask();

            }

        }

 

"操作引擎(Processing Engine)" 是一个任务容器，EndRequest中对添加到容器内的任务进行同步处理。关于"操作引擎"我们在适当的时候来分析。
