如何在ASP.Net MVC中执行301永久重定向路由

Question

如何在ASP.NET MVC中执行HTTP 301永久重定向路由？

Answer 1

创建一个继承自ActionResult ...

的类

    public class PermanentRedirectResult : ActionResult
    {    
        public string Url { get; set; }

        public PermanentRedirectResult(string url)
        {
            this.Url = url;
        }

        public override void ExecuteResult(ControllerContext context)
        {
            context.HttpContext.Response.StatusCode = (int)HttpStatusCode.MovedPermanently;
            context.HttpContext.Response.RedirectLocation = this.Url;
            context.HttpContext.Response.End();
        }
    }

然后使用它......

        public ActionResult Action1()
        {          
            return new PermanentRedirectResult("http://stackoverflow.com");
        }

Answer 2

您需要301重定向a 302 is temporary, a 301 is permanent。在此示例中，context是HttpContext：

context.Response.Status = "301 Moved Permanently";
context.Response.StatusCode = 301;
context.Response.AppendHeader("Location", nawPathPathGoesHere);
