asp.net-mvc – 在asp.NET MVC 3中响应HEAD请求

是否有一种方法在Asp.NET MVC 3中以通用方式响应HEAD请求,而不是将HEAD属性添加到单个方法.

解决方法

创建一个RouteConstraint路由,如下所示：

routes.MapRoute(
    "HEAD Requests","{*fullPath}",new { controller = "Head",action = "Index" },new { fullPath = new MustBeHeadRequest() }
);

public class MustBeHeadRequest : IRouteConstraint
{
    public bool Match(HttpContextBase httpContext,Route route,string parameterName,RouteValueDictionary values,RouteDirection routeDirection)
    {
        return httpContext.Request.HttpMethod.ToLowerInvariant() == "head";
    }
}

将路线放置在路线顶部或附近.当HEAD请求进入时,它将被路由到HeadController的Index操作.
