在asp.net mvc項目中路由遺留的asp.net鏈接

Question

我需要在我的asp.net mvc項目中支持以下url一段時間。

http://www.example.com/d.aspx?did=1234 

我需要將此映射到此URL。

http://www.example.com/Dispute/Detail/1234 

我已經看過以下信息。

http://blog.eworldui.net/post/2008/04/ASPNET-MVC---Legacy-Url-Routing.aspx

ASP.Net MVC routing legacy URLs passing querystring Ids to controller actions

在努力遵循這個我能得到第一個URL工作，但那麼所有其他的URL被破壞。 任何人都可以看到我的出錯位置嗎？

這是我的路線。

public static void RegisterRoutes(RouteCollection routes) 
    { 
     // all my other routes 

     // Legacy routes 
     routes.Add(
      "Legacy", 
      new LegacyRoute(
      "d.aspx", 
      "LegacyDirectDispute", 
      new LegacyRouteHandler()) 
     ); 

     routes.MapRoute(
      "LegacyDirectDispute", 
      "Dispute/Details/{id}", 
      new { controller = "Dispute", action = "Details", id = "" } 
     ); 

     routes.MapRoute(
      "Default",            // Route name 
      "{controller}/{action}/{id}",      // URL with parameters 
      new { controller = "Home", action = "Index", id = "" } // Parameter defaults 
     ); 
    } 

這是我使用的global.asax.cs中的代碼。

public class LegacyRoute : Route 
{ 
    public string RedirectActionName { get; set; } 
    public LegacyRoute(string url, string redirectActionName, IRouteHandler routeHandler) 
    : base(url, routeHandler) 
    { 
    RedirectActionName = redirectActionName; 
    } 
} 

// The legacy route handler, used for getting the HttpHandler for the request 
public class LegacyRouteHandler : IRouteHandler 
{ 
    public IHttpHandler GetHttpHandler(RequestContext requestContext) 
    { 
    return new LegacyHandler(requestContext); 
    } 
} 

// The legacy HttpHandler that handles the request 
public class LegacyHandler : MvcHandler 
{ 
    private RequestContext requestContext; 
    public LegacyHandler(RequestContext requestContext) 
    : base(requestContext) 
    { 
    this.requestContext = requestContext; 
    } 

    protected override void ProcessRequest(HttpContextBase httpContext) 
    { 
    string redirectActionName = ((LegacyRoute)RequestContext.RouteData.Route).RedirectActionName; 

    var queryString = requestContext.HttpContext.Request.QueryString; 
    foreach (var key in queryString.AllKeys) 
    { 
    if (key.Equals("did")) 
    { 
    requestContext.RouteData.Values.Add("id", queryString["did"]); 
    } 
    else 
    { 
    requestContext.RouteData.Values.Add(key, queryString[key]); 
    } 
    } 

    VirtualPathData path = RouteTable.Routes.GetVirtualPath(requestContext, redirectActionName, 
       requestContext.RouteData.Values); 

    if (path != null) 
    { 
    httpContext.Response.Status = "301 Moved Permanently"; 
    httpContext.Response.AppendHeader("Location", path.VirtualPath); 
    } 
    } 
}

你可以只創建一個名爲d.aspx在站點根類似的文件，內容如下：

<script runat="server"> 
protected void Page_Load(object sender, EventArgs e) 
{ 
    Response.Redirect(string.Format("http://{0}/Dispute/Detail/{1}", Request.Url.Host, Request.QueryString.Get("did"))); 
} 
</script>

這裏是我落得這樣做來解決我的問題，直到我看到了簡單的答案@grenade發佈。我在這裏發現了這種技術http://www.mikesdotnetting.com/Article/108/Handling-Legacy-URLs-with-ASP.NET-MVC。

public class LegacyUrlRoute : RouteBase 
{ 
    public override RouteData GetRouteData(HttpContextBase httpContext) 
    { 
     const string status = "301 Moved Permanently"; 
     var request = httpContext.Request; 
     var response = httpContext.Response; 
     var legacyUrl = request.Url.ToString(); 
     var newUrl = ""; 
     var id = request.QueryString.Count != 0 ? request.QueryString[0] : ""; 

     if (legacyUrl.Contains("d.aspx")) 
     { 
      newUrl = "Dispute/Details/" + id; 
      response.Status = status; 
      response.RedirectLocation = newUrl; 
      response.End(); 
     } 
     return null; 
    } 

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, 
       RouteValueDictionary values) 
    { 
     return null; 
    } 
} 

public static void RegisterRoutes(RouteCollection routes) 
{ 
    // all my other routes 
    routes.Add(new LegacyUrlRoute()); 
}

如何添加一個地圖頁面路線：

Routes.MapPageRoute(
      "Legacy", // Route name 
      "d.aspx", // URL 
      "~/pathfromBaseUrl/d.aspx" // File 
      ); 

然後在你的aspx使用本/視圖

Html.RouteLink("MyLinkName", "Legacy")
