Asp.net web api操作筛选器中设置的CallContext值未流向控制器操作
我有一个asp.net web api,其中我们在OnActionExecuted中使用TransactionScope(仅用于POST、PUT和DELETE,但不用于GET)启动事务,执行全局操作筛选器,然后在OnActionExecuted中完成或回滚它。 最近,我们决定进行更改,以便至少可以为GET调用添加SqlAzureExecutionStrategy(因为它仅在没有用户启动的事务时才起作用),以便可以为数据获取处理瞬时故障。我遵循本文的思路,在我们的应用程序中实现了相同的东西 创建了一个新的数据库配置类Asp.net web api操作筛选器中设置的CallContext值未流向控制器操作,asp.net,asp.net-web-api2,custom-action-filter,callcontext,Asp.net,Asp.net Web Api2,Custom Action Filter,Callcontext,我有一个asp.net web api,其中我们在OnActionExecuted中使用TransactionScope(仅用于POST、PUT和DELETE,但不用于GET)启动事务,执行全局操作筛选器,然后在OnActionExecuted中完成或回滚它。 最近,我们决定进行更改,以便至少可以为GET调用添加SqlAzureExecutionStrategy(因为它仅在没有用户启动的事务时才起作用),以便可以为数据获取处理瞬时故障。我遵循本文的思路,在我们的应用程序中实现了相同的东西 创建了
public class AzureDbConfiguration : DbConfiguration
{
public const string CallContextKey = "SuspendExecutionStrategy";
public AzureDbConfiguration()
{
this.SetExecutionStrategy("System.Data.SqlClient", () => SuspendExecutionStrategy
? (IDbExecutionStrategy)new DefaultExecutionStrategy()
: new SqlAzureExecutionStrategy());
}
public static bool SuspendExecutionStrategy
{
get
{
return (bool?)CallContext.LogicalGetData(CallContextKey) ?? false;
}
set
{
CallContext.LogicalSetData(CallContextKey, value);
}
}
}
每当需要启动事务时,将suspendExecutionStrategy设置为true
public override void OnActionExecuting(HttpActionContext actionContext)
{
//checks if it is not a GET call
if (RequiresTransactionInitiation(actionContext))
{
AzureDbConfiguration.SuspendExecutionStrategy = true;
var transactionCompleter = new TransactionCompleter(GetDependencyScope(actionContext));
transactionCompleter.UnitOfWork.StartTransaction(System.Data.IsolationLevel.ReadCommitted);
}
base.OnActionExecuting(actionContext);
}
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
//checks if it is not a GET call
if (RequiresTransactionCompletion(actionExecutedContext))
{
var transactionCompleter = new TransactionCompleter(GetDependencyScope(actionExecutedContext));
if (actionExecutedContext.Exception == null)
{
transactionCompleter.Complete();
AddEventsToResponseHeader(transactionCompleter.MessageTransactions.OfType<IEventTransaction>(), actionExecutedContext.Response);
}
else
{
transactionCompleter.Rollback();
}
//*********** line is added to just test the value of the property .This always return false.**********
var testValue = AzureDbConfiguration.SuspendExecutionStrategy;
}
base.OnActionExecuted(actionExecutedContext);
}
控制器操作和OnActionExecuted中Thread.CurrentThread.ExecutionContext.ToStringJson()的值
{
"LogicalCallContext": {
"E2ETrace.ActivityID": "80000013-0003-fd00-b63f-84710c7967bb",
"ApplicationInsights.OwinExtensions.OperationIdContext": "1c218be6-1fbb-44bf-b994-4db84115b5a3",
"ApplicationInsights.OwinExtensions.OperationParentIdContext": "72d35ac6-a394-4205-8452-a95b36f8857a",
})
所以我的问题是,执行上下文如何从操作过滤器更改为控制器操作,以及执行上下文中的所有其他值如何仍然保留
{
"LogicalCallContext": {
"E2ETrace.ActivityID": "80000013-0003-fd00-b63f-84710c7967bb",
"ApplicationInsights.OwinExtensions.OperationIdContext": "1c218be6-1fbb-44bf-b994-4db84115b5a3",
"ApplicationInsights.OwinExtensions.OperationParentIdContext": "72d35ac6-a394-4205-8452-a95b36f8857a",
})
