目前我正在试图以301重定向添加到我的路线在MVC试图将功能添加到MvcHandler
做到这一点我试图从MvcHandler继承。 处理程序以正确的值立即获取。但我永远不能调试重写的方法。
有人可以告诉我一个这样的工作尝试吗?在asp.net管只是似乎在做自己的事......
public class CodeHttpHandler : MvcHandler
{
public CodeHttpHandler(RequestContext p_requestContext)
: base(p_requestContext)
{
}
protected override void ProcessRequest(HttpContext p_httpContext)
{
}
protected override void ProcessRequest(HttpContextBase p_httpContext)
{
}
}
更新:
这是我迄今发现的解决方案:
public class CodeRouteHandler : IRouteHandler
{
public System.Web.IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return new CodeHandler(requestContext);
}
}
public class CodeRouteConstants
{
public const string CODE = "code";
public const string REDIRECT = "Redirect";
}
public class CodeHandler : MvcHandler
{
public CodeHandler(RequestContext requestContext)
: base(requestContext)
{
}
private int? HandleCodedRoute(System.Web.HttpContextBase httpContext)
{
var context = httpContext.Request.RequestContext.RouteData;
if (context.DataTokens.ContainsKey(CodeRouteConstants.CODE))
{
var statusCode = Int32.Parse(context.DataTokens[CodeRouteConstants.CODE] as string ?? "500");
httpContext.Response.StatusCode = statusCode;
if (context.DataTokens.ContainsKey(CodeRouteConstants.REDIRECT))
{
var redirectionMap = context.DataTokens[CodeRouteConstants.REDIRECT] as string ?? "404";
foreach (var v in context.Values)
{
redirectionMap = redirectionMap.Replace(string.Format("{{{0}}}", v.Key), v.Value as string);
}
httpContext.Response.AddHeader("Location", redirectionMap);
}
httpContext.Response.End();
return statusCode;
}
return null;
}
protected override System.IAsyncResult BeginProcessRequest(System.Web.HttpContext httpContext, System.AsyncCallback callback, object state)
{
var statusCode = HandleCodedRoute(new HttpContextWrapper(httpContext));
if (statusCode.HasValue)
{
return null;
}
return base.BeginProcessRequest(httpContext, callback, state);
}
protected override System.IAsyncResult BeginProcessRequest(System.Web.HttpContextBase httpContext, System.AsyncCallback callback, object state)
{
return base.BeginProcessRequest(httpContext, callback, state);
}
protected override void ProcessRequest(System.Web.HttpContext httpContext)
{
base.ProcessRequest(httpContext);
}
protected override void ProcessRequest(System.Web.HttpContextBase httpContext)
{
base.ProcessRequest(httpContext);
}
}
好<我验证了我确实在构造函数中获得了正确的信息。一切都在那里,而且据说,我找到了正确的处理程序。但我的逻辑根本不会被调用,我得到的默认行为,而不是我编码。 这让我感到困惑 – 2010-05-16 13:15:02
我有一个异步模型的问题 我目前得到“无法重定向HTTP头后已发送。”错误。 你有没有克服过这个? – 2010-05-17 13:36:28
