c# - 从 WebApi MessageHandler 获取 ActionDescriptor

Question

我如何从 MessageHandler 中检索 ActionDescriptor？

我可以使用以下代码在 SendAsync 方法中获取 ContractDescriptor:

var config = request.GetConfiguration();
_controllerSelector = config.Services.GetService(typeof(IHttpControllerSelector)) as IHttpControllerSelector;
HttpControllerDescriptor descriptor = _controllerSelector.SelectController(request);

但我不知道如何获取 ActionDescriptor。

谢谢!!

您可以使用 System.Net.Http.HttpRequestMessageExtensions 的扩展:

//using System.Net.Http;

var actionDescriptor = request.GetActionDescriptor();
