为什么在MessageHandler的MVC请求被执行？

本文介绍了为什么在MessageHandler的MVC请求被执行？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个项目包括MVC和Web API控制器。我有，

  GlobalConfiguration.MessageHandlers.Insert（0，新MessageHandler1（））;

但是，当我申请一个MVC控制器，它执行这个处理程序。这伤害了我，因为燮pressDefaultHostAuthentication是在MVC要求执行PassiveAuthenticationMessageHandler处理程序。我已经把一个破发点上MessageHandler1.SendAsync，发现System.Web.HttpContext.Current.Handler = {} System.Web.Mvc.MvcHandler其中确认它是MVC的请求。

解决方案

我使用自定义的MessageHandler刚修好它，

  GlobalConfiguration.Sup pressDefaultHostAuthentication（）;
GlobalConfiguration.Filters.Add（新HostAuthenticationFilter（OAuthOptions.AuthenticationType））;
GlobalConfiguration.MessageHandlers.Insert（0，新ResetMvcPrincipalMessageHandler（））;    公共类ResetMvcPrincipalMessageHandler：DelegatingHandler
    {
        保护异步覆盖任务其中p型Htt presponseMessage＆GT; SendAsync（
            HTT prequestMessage请求的CancellationToken的CancellationToken）
        {
            VAR URL = request.RequestUri.AbsolutePath;
            如果（！url.Contains（/ API /））//而不是web API请求
            {
                VAR本金= request.GetRequestContext（）校长。
                VAR响应=等待base.SendAsync（请求的CancellationToken）;;
                request.GetRequestContext（）主要=本金。
                返回响应;
            }
            返回等待base.SendAsync（请求的CancellationToken）;
        }
    }

I have a project include MVC and Web API controllers. I have,

 GlobalConfiguration.MessageHandlers.Insert(0, new MessageHandler1());

But when I request a MVC controller it executes this handler. It hurting me because SuppressDefaultHostAuthentication is executing PassiveAuthenticationMessageHandler handler on MVC request. I have put a break-point on MessageHandler1.SendAsync and found that System.Web.HttpContext.Current.Handler = {System.Web.Mvc.MvcHandler} which confirm that it is MVC request.

解决方案

I just fix it using custom MessageHandler,

GlobalConfiguration.SuppressDefaultHostAuthentication();
GlobalConfiguration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));
GlobalConfiguration.MessageHandlers.Insert(0, new ResetMvcPrincipalMessageHandler());

    public class ResetMvcPrincipalMessageHandler : DelegatingHandler
    {
        protected async override Task<HttpResponseMessage> SendAsync(
            HttpRequestMessage request, CancellationToken cancellationToken)
        {
            var url = request.RequestUri.AbsolutePath;
            if (!url.Contains("/api/"))// not web api request
            {
                var principal = request.GetRequestContext().Principal;
                var response = await base.SendAsync(request, cancellationToken);;
                request.GetRequestContext().Principal = principal;
                return response;
            }
            return await base.SendAsync(request, cancellationToken);
        }
    }
