Asp.net 如何在内容处理程序中设置HttpResponse StatusDescription？

我试图在HTTP响应中设置自定义HTTP状态头。例如：

400 Why do you want to do that

我是通过在

IHttpHandler

中设置

HttpResponse

的

StatusDescription

来实现的

<%@ WebHandler Language="C#" Class="Foo" %>

using System;
using System.Web;

public class Foo : IHttpHandler
{

    public void ProcessRequest(HttpContext context)
    {
        context.Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;
        context.Response.StatusDescription = "Why do you want to do that";

            //Unnecessary; the string already contains this
        context.Response.Status = "400 Why do you want to do that";

        context.Response.ContentType = "text/plain";
        context.Response.Write("Hello World");
    }

    public bool IsReusable { get { return false; } }
}

在通用处理程序中，如何更改

HttpResponse

头的

StatusDescription

花言巧语 有三个属性：

• int StatusCode

  ：

  400

• 字符串状态描述

  ：

  错误请求

• 字符串状态

  ：

  400错误请求

设置

StatusCode

将改变

StatusDescription

和

Status

                    StatuCode  StatusDescription  Status              
==================  =========  =================  ====================
initial             200        OK                 200 OK
StatusCode=400;
                    400        Bad Request        400 Bad Request
StatusDescription = "Too much want";
                    400        Too much want      400 Too much want

它的工作方式也是相反的：

                    StatuCode  StatusDescription  Status              
==================  =========  =================  ====================
initial             200        OK                 200 OK
StatusDescription="Brilliant";
                    200        Brilliant          200 Brilliant
StatusCode=451;
                    451        Brilliant          451 Brilliant

另一方面

                    StatuCode  StatusDescription  Status              
==================  =========  =================  ====================
initial             200        OK                 200 OK
Status="451 Brilliant"
                    451        Brilliant          451 Brilliant

花言巧语 发件人：

6.1.1状态代码和原因短语

下面给出了为HTTP/1.1定义的数字状态代码的各个值以及相应原因短语的示例集。这里列出的原因短语只是建议——它们可以被本地等价物替换，而不会影响协议

                    StatuCode  StatusDescription  Status              
==================  =========  =================  ====================
initial             200        OK                 200 OK
Status="451 Brilliant"
                    451        Brilliant          451 Brilliant
