永久重定向在ASP.Net中静态文件的传统路由MVC

Question

我们的旧ASP.net站点将静态图像存储在根目录下的子目录中，名为/images。

我们新的ASP.net MVC网站/内容的新布局存储这些图片/图片

我已经改变了所有的网页在现场，以应付新的文件夹结构，但我d喜欢从旧静态图像到新位置设置永久重定向。

我们的网站是托管的，我无法控制IIS，那么解决此问题的最佳方法是什么？

Answer 1

我用下面的代码为我的MVC 2网站：

// The legacy route class that exposes a RedirectActionName 
public class LegacyRoute : Route 
{ 
    public LegacyRoute(string url, string redirectActionName, IRouteHandler routeHandler) 
     : base(url, routeHandler) 
    { 
     RedirectActionName = redirectActionName; 
     Defaults = new RouteValueDictionary(new { controller = "Home", action = "Index"}); // is not actually called 
    } 

    public string RedirectActionName { get; set; } 
} 

// The legacy route handler, used for getting the HttpHandler for the request 
public class LegacyRouteHandler : MvcRouteHandler 
{ 
    protected override IHttpHandler GetHttpHandler(RequestContext requestContext) 
    { 
     requestContext.HttpContext.Response.Write("success"); 
     return new LegacyHandler(requestContext); 
    } 
} 

// The legacy HttpHandler that handles the request 
public class LegacyHandler : MvcHandler 
{ 
    public LegacyHandler(RequestContext requestContext) : base(requestContext) 
    { 
     requestContext.HttpContext.Response.Write("success"); 
     ProcessRequest(requestContext.HttpContext); 
    } 

    protected override void ProcessRequest(HttpContextBase httpContext) 
    { 
     string redirectActionName = ((LegacyRoute) RequestContext.RouteData.Route).RedirectActionName; 
     var route = new Route(redirectActionName, ((LegacyRoute)RequestContext.RouteData.Route).Defaults, new MvcRouteHandler()); 

     // Copy all of the querystring parameters and put them within RouteContext.RouteData.Values 
     var values = new Dictionary<string, object>(); 
     foreach (var s in RequestContext.RouteData.Values) 
     { 
      values.Add(s.Key, s.Value); 
     } 
     foreach (var s in httpContext.Request.QueryString.AllKeys) 
     { 
      values.Add(s, httpContext.Request.QueryString[s]); 
     } 
     var data = route.GetVirtualPath(RequestContext, new RouteValueDictionary(values)); 

     httpContext.Response.Status = "301 Moved Permanently"; 
     httpContext.Response.AppendHeader("Location", "/" + data.VirtualPath + "/"); 
     httpContext.Response.End(); 
    } 
} 

然后，我只是传统的路由添加到我的路线图：

routes.Insert(13, new LegacyRoute("search", "search/{query}", new LegacyRouteHandler()));
