在的WebAPI，我应该在哪里保存调用之间的数据，以我的ActionFilter？ [英] In WebApi, where should I save data between calls to my ActionFilter?

问题描述

我有一个<一个href="http://msdn.microsoft.com/en-us/library/system.web.http.filters.actionfilterattribute%28v=vs.108%29.aspx"相对=nofollow> ActionFilterAttribute ，做一些东西，之前和目标的行动之后。我想保存执行呼叫的状态在已执行通话使用 - 但这里我要救这个数据？

I have an ActionFilterAttribute which does some stuff both before and after the target action. I would like to save the state of the Executing call for use in the Executed call - but where should I save this data?

我希望是这样的：

public override void OnActionExecuting(HttpActionContext actionContext)
{
    actionContext.SavedState = Precomputation();
}

public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
    var pre = actionExecutedContext.ActionContext.SavedState;
    Postcomputation(pre);
}

但 SavedState 实际上不存在的，当然。我应该用什么代替呢？

but SavedState doesn't actually exist, of course. What should I use instead?

推荐答案

将项目添加到 actionContext.Request.Properties 的要求。
