相关疑难解决方法(0)

我一直在寻找一个小时试图弄清楚为什么这不起作用.

我有一个带有WebAPI的ASP.Net MVC 5应用程序.我正在尝试获取Request.GetOwinContext().身份验证,但我似乎无法找到如何包含GetOwinContext.这是我的代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using TaskPro.Models;

namespace TaskPro.Controllers.api
{
    public class AccountController : ApiController
    {
        [HttpPost]
        [AllowAnonymous]
        public ReturnStatus Login(LoginViewModel model)
        { 
            if (ModelState.IsValid)
            {
                var ctx = Request.GetOwinContext(); // <-- Can't find this

                return ReturnStatus.ReturnStatusSuccess();
            }

            return base.ReturnStatusErrorsFromModelState(ModelState);
        }
    }
}

从我读过的内容来看,它应该是System.Net.Http的一部分,但我已经包含了它,但它仍然没有解决.Ctrl-Space也没有给我任何intellisense选项.

我在这里错过了什么？

我在ASP.NET WebApi2设置中遇到了一些OWIN的困难.重启后的第一个请求导致异常:

    [ObjectDisposedException: Cannot access a disposed object.
    Object name: 'System.Net.Http.HttpMessageInvoker'.]

我已经使用webapi项目和以下OWIN启动(并且没有global.asax)以简化形式重现了该问题:

public class Startup
{
    public void Configuration(IAppBuilder app) {
        var config = new HttpConfiguration();
        config.MapHttpAttributeRoutes();

        // ---- simulate long running initialization code -------
        Thread.Sleep(3000);
        // ------------------------------------------------------

        app.UseWebApi(config);
    } …
