当前 http 上下文的 HTTP 动词

Question

如何找到用于访问应用程序的 http 动词（POST、GET、DELETE、PUT）？我正在寻找 httpcontext.current 但似乎没有是任何给我信息的财产。谢谢

Answer 1

使用HttpContext.Current.Request.HttpMethod。

请参阅：http://msdn.microsoft.com/en-us/library/ system.web.httprequest.httpmethod.aspx

Answer 2

在 ASP.NET CORE 2.0 中，您可以使用以下命令获取（或设置）当前上下文的 HTTP 谓词：

Request.HttpContext.Request.Method

Answer 3

HttpContext.Current.Request.HttpMethod

Answer 4

if (HttpContext.Request.HttpMethod == HttpMethod.Post.Method) 
{
        // The action is a post 
}
    
if (HttpContext.Request.HttpMethod == HttpMethod.put.Method)
{
        // The action is a put 
}

if (HttpContext.Request.HttpMethod == HttpMethod.DELETE.Method)
{
        // The action is a DELETE
}

if (HttpContext.Request.HttpMethod == HttpMethod.Get.Method)
{
        // The action is a Get
}

Answer 5

用于获取 Get 和 Post

string method = HttpContext.Request.HttpMethod.ToUpper();

Answer 6

您还可以使用： HttpContext.Current.Request.RequestType

Answer 7

在 ASP.NET Core v3.1 中，我使用注入到构造函数中的 HttpContextAccessor 接口检索当前的 HTTP 动词，例如

private readonly IHttpContextAccessor _httpContextAccessor;

public MyPage(IHttpContextAccessor httpContextAccessor)
{
    _httpContextAccessor = httpContextAccessor;
}

用法：

_httpContextAccessor.HttpContext.Request.Method

Answer 8

HttpContext.Current.Request.HttpMethod 返回字符串，但最好使用枚举 HttpVerbs。似乎没有内置方法来获取当前动词作为枚举，所以我为它编写了助手应用程序的助手

类

public static class HttpVerbsHelper
    {
        private static readonly Dictionary<HttpVerbs, string> Verbs =
            new Dictionary<HttpVerbs, string>()
            {
                {HttpVerbs.Get, "GET"},
                {HttpVerbs.Post, "POST"},
                {HttpVerbs.Put, "PUT"},
                {HttpVerbs.Delete, "DELETE"},
                {HttpVerbs.Head, "HEAD"},
                {HttpVerbs.Patch, "PATCH"},
                {HttpVerbs.Options, "OPTIONS"}
            };

        public static HttpVerbs? GetVerb(string value)
        {
            var verb = (
                from x in Verbs
                where string.Compare(value, x.Value, StringComparison.OrdinalIgnoreCase) == 0
                select x.Key);
            return verb.SingleOrDefault();
        }
    }

基控制器类

public abstract class BaseAppController : Controller
    {
        protected HttpVerbs? HttpVerb
        {
            get
            {
                var httpMethodOverride = ControllerContext.HttpContext.Request.GetHttpMethodOverride();
                return HttpVerbsHelper.GetVerb(httpMethodOverride);
            }
        }
}
