使用MVCSiteMapProvider中的自定義路由數據構建自定義網址

Question

我們正在爲我們的網站使用MVCSiteMapProvider。

這是場景... 想象一下員工的頁面，/employee/123。這將有員工詳細信息以及一系列需要在url中維護123的鏈接。

某些鏈接需要指向傳統網址，因此類似於/demographics/?employeeID=123這樣的情況。這些鏈接中大約有30個，因此將這些鏈接保留在站點地圖中勢在必行。

任何有關如何解決這個問題的建議都會有所幫助。

您可以創建一個DynamicNodeProvider來處理這種情況。循環播放時只需添加「相關」節點，以便它們全部顯示在一起。該id存儲在RouteValues中並緩存給所有用戶，因此站點地圖不會在請求之間將其忘記。

public class EmployeeDynamicNodeProvider 
    : DynamicNodeProviderBase 
{ 
    CRUDExample db = new CRUDExample(); 

    public override IEnumerable<DynamicNode> GetDynamicNodeCollection(ISiteMapNode node) 
    { 
     var result = new List<DynamicNode>(); 

     var employees = db.Employee; 
     foreach (var employee in employees) 
     { 
      var employeeKey = "Product_" + employee.Id.ToString(); 

      // Create the "Details" node for the employee 
      var employeeNode = new DynamicNode(employeeKey, "EmployeeParentNodeKey", employee.Name, employee.Name, "Employee", "Details"); 

      // Set the "id" route value so the match will work. 
      employeeNode.RouteValues.Add("id", employee.Id); 

      // Add the node to the result 
      result.Add(employeeNode); 


      // Create the "Edit" node for the employee 
      var employeeEditNode = new DynamicNode("EmployeeEdit_" + employee.Id.ToString(), employeeKey, "Edit", "Edit", "Employee", "Edit"); 

      // Set the "id" route value of the edit node 
      employeeEditNode.RouteValues.Add("id", employee.Id); 

      // Add the node to the result 
      result.Add(employeeEditNode); 


      // Create the "Delete" node for the employee 
      var employeeDeleteNode = new DynamicNode("EmployeeDelete_" + employee.Id.ToString(), employeeKey, "Delete", "Delete", "Employee", "Delete"); 

      // Set the "id" route value of the delete node 
      employeeDeleteNode.RouteValues.Add("id", employee.Id); 

      // Add the node to the result 
      result.Add(employeeDeleteNode); 


      // Create the "Demographics" node for the employee 
      var employeeDemographicsNode = new DynamicNode("EmployeeDemographics_" + employee.Id.ToString(), employeeKey, "Demographics", "Demographics", "Employee", "Demographics"); 

      // Set the "id" route value of the delete node 
      employeeDemographicsNode.RouteValues.Add("id", employee.Id); 

      // Add the node to the result 
      result.Add(employeeDemographicsNode); 
     } 

     return result; 
    } 
} 

至於URL，它是System.Web.Routing，它將路由值轉換爲URL。但是，如果URL很複雜，則可以使用其他幾個選項：

1. 使用站點地圖節點的Url屬性而不是路由值。
2. 創建一個自定義URL解析器來處理URL的特殊情況。
