ASP.NET MVC路由扩展：链接和URL的生成(6)

   2: {
   3:     protected void Page_Load(object sender, EventArgs e)
   4:     {
   5:         HttpRequest request = new HttpRequest("default.aspx", "http://localhost:3721/home/index/002", null);
   6:         HttpResponse response = new HttpResponse(new StringWriter());
   7:         HttpContext context = new HttpContext(request, response);
   8:         HttpContextBase contextWrapper = new HttpContextWrapper(context);
   9: 
  10:         RouteData routeData = new RouteData();
  11:         routeData.Values.Add("controller", "home");
  12:         routeData.Values.Add("action", "index");
  13:         routeData.Values.Add("id", "002");
  14:         RequestContext requestContext = new RequestContext(contextWrapper, routeData);
  15:         RouteHelper helper = new RouteHelper(requestContext);
  16: 
  17:         Response.Write(helper.Action("GetProduct", "Products",new {id="002"}) + "<br/>");
  18:         Response.Write(helper.Action("GetProduct", "Products", new { id = "002" }, "http") + "<br/>");
  19:         Response.Write(helper.Action("GetProduct", "Products", new RouteValueDictionary { { "id", "002" } },
  20:             "https", "www.artech.com") + "<br/>");
  21:     }
  22: }
我们通过调用RouteHelper其中其中三个Action方法重载生成出三个Url并写入HTTP回复。对于第一个方法调用，我们指定了Action和Controller的名称以及针对变量{id}的值；第二次在这基础上显示指定了传输协议名称http；第三个在同时指定了协议名称（https）和主机名称（www.artech.com）。当我们通过浏览器访问该Web页面的时候，我们会得到如下图所示3个URL。
