找不到方法:"System.Net.Http.HttpRequestMessage System.Web.Http.Controllers.HttpActionContext.get_Request()" [英] Method not found: 'System.Net.Http.HttpRequestMessage System.Web.Http.Controllers.HttpActionContext.get_Request()'

问题描述

我已经创建了一个过滤器属性

I have created One Filter Attribute

public class AuthFilterAttribute : System.Web.Http.Filters.ActionFilterAttribute
{
    public AuthFilterAttribute()
    {

    }

    public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
    {

    }
}

我已经在global.asax.cs中注册了此过滤器.

I have registered this filter inside the global.asax.cs.

当我尝试使用 Postman 调用我的Web API时，显示错误:

When I am trying to call my web API using Postman it is showing the error:

找不到方法:"System.Net.Http.HttpRequestMessage System.Web.Http.Controllers.HttpActionContext.get_Request()".

Method not found: 'System.Net.Http.HttpRequestMessage System.Web.Http.Controllers.HttpActionContext.get_Request()'.

我的项目目标框架是4.6.1，而System.Net.Http版本是4.2.0.0

My project target framework is 4.6.1 and the System.Net.Http version is 4.2.0.0

我的API如下:

[AuthFilter]
public class ScheduleApiController : BaseApiController
{
    [Route("api/v1/schedules")]
    [HttpGet]
    public IHttpActionResult GetSchedules()
    {
    }
}

我知道之前曾有人问过这个问题，但是没有一个解决方案对我有用.

I know this question has been asked before but none of the solutions worked for me.

请帮助我解决此问题.

推荐答案

您是否偶然引用.NET标准库.我遇到了这个问题，并通过绑定重定向解决了这个问题:

Are you referencing a .NET Standard Library by any chance. I ran into this problem and solved it with a Binding Redirect:

  <dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.2.0.0" />
  </dependentAssembly>
