Question

我有一个基本的ASP.NET MVC 3应用程序。我有一个基本的行动,看起来像如下:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult AddItem(string id, string name, string description, string username)
{
  // Do stuff
  return Json(new { statusCode = 1 });
}

我试图让某人通过一个JQuery移动应用程序访问此动作, 该应用程序将在电话卡中托管。有人告诉我, 我需要在我的信头中返回 < code> Access- control- Allow- Oligin:\\\ / code> 。但是, 我不知道如何在信头中返回这个动作。有人能告诉我怎么做吗?

非常感谢

Answer 1

Response.AppendHeader("Access-Control-Allow-Origin", "*");

Answer 2

    public class HttpHeaderAttribute : ActionFilterAttribute
    {
        /// 
        /// Gets or sets the name of the HTTP Header.
        /// 
        /// The name.
        public string Name { get; set; }

        /// 
        /// Gets or sets the value of the HTTP Header.
        /// 
        /// The value.
        public string Value { get; set; }

        /// 
        /// Initializes a new instance of the  class.
        /// 
        /// The name.
        /// The value.
        public HttpHeaderAttribute(string name, string value)
        {
            Name = name;
            Value = value;
        }

        public override void OnResultExecuted(ResultExecutedContext filterContext)
        {
            filterContext.HttpContext.Response.AppendHeader(Name, Value);
            base.OnResultExecuted(filterContext);
        }
   }

[HttpHeader("Access-Control-Allow-Origin","*")]
    public ActionResult myaction(int id)
    {
        // ...
    }
