HttpResponseMessage在Web Api(.NET 4.5)中不起作用 [英] HttpResponseMessage not working in Web Api (.NET 4.5)

问题描述

我阅读了 http://www.asp.net/web-api/overview/security/working-with-ssl-in-web-api ，并尝试使用该页面中的代码:

I read http://www.asp.net/web-api/overview/security/working-with-ssl-in-web-api and tried to use the code from that page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web;
using System.Web.Http;
using System.Web.Http.Filters;
using System.Web.Http.Controllers;

public class RequireHttpsAttribute : AuthorizationFilterAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        if (actionContext.Request.RequestUri.Scheme != Uri.UriSchemeHttps)
        {
            actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
            {
                ReasonPhrase = "HTTPS Required"
            };
        }
        else
        {
            base.OnAuthorization(actionContext);
        }
    }
}

构建时没有出现错误，但是运行时出现此错误:

When I build I don't get an error, but runtime gives this error:

CS0012:类型'System.Net.Http.HttpRequestMessage'是在未引用的程序集中定义的.您必须添加对程序集'System.Net.Http，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'的引用.

CS0012: The type 'System.Net.Http.HttpRequestMessage' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

我在我的项目的references文件夹中有对System.Net.Http的引用.如果我看一下它的属性，它会显示版本4.0.0.0和运行时版本4.0.30319.我的项目属性说目标框架是.NET 4.5.

I have got a reference to System.Net.Http in my references folder of my project. If I look at it's properties, it says Version 4.0.0.0 and Runtime Version 4.0.30319. My project properties says target framework is .NET 4.5.

我在VS2013 Express中的IntelliSense也不想获取与HttpResponseMessage或HttpRequestMessage有关的任何内容.

My IntelliSense in VS2013 Express also doesn't want to pick up anything to do with HttpResponseMessage or HttpRequestMessage.

我尝试删除引用并重新添加它，但无济于事.

I've tried removing the reference and re-adding it, but to no avail.

任何帮助将不胜感激.

推荐答案

好吧，我可能会迟到，但以防万一有人遇到这个问题.

Well, I might be late, but just in case someone else faced this problem.

首先，您需要找到一个字符串:

First of all, you need to find a string:

<compilation debug="true" targetFramework="4.5"/>

并使其不像这样自动关闭标签:

And make it not self-closing tag like that:

<compilation debug="true" targetFramework="4.5">
</compilation>

接下来，在其中添加带有您之前所豪宅信息的Assemblys标签，如下所示:

Next, add assemblies tag inside with assembly information you mansioned before, so it looks like this:

<compilation debug="true" targetFramework="4.5">
      <assemblies>
        <add assembly="System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
      </assemblies>
</compilation>

并重建您的解决方案.看看

And rebuild your solution. Take a look at this link.
