微信公众号禁止设置ngrok地址的解决办法

最近想改一下以前测试公众号的地址为ngrok2的亚洲节点，结果提示安全问题，禁止设置。原来是微信把类似花生壳ngrok等这些地址都封了。

现在暂时用的解决办法是在外网服务器上做一个转发程序，只需一个handler

using System.Configuration;
using System.Diagnostics;
using System.Net;
using System.Web;

namespace WechatProxy
{
    public class WechatHandler : IHttpHandler
    {
        private TraceSource trace;
        public WechatHandler()
        {
            IsReusable = true;
            trace = new TraceSource("trace");
        }
        public void ProcessRequest(HttpContext context)
        {

            var url = string.Format("http://{0}{1}{2}", ConfigurationManager.AppSettings["host"],
                context.Request.Path,
                context.Request.QueryString.Count > 0 ? ("?" + context.Request.QueryString) : "");
            trace.TraceInformation(url);
            var request = WebRequest.Create(url);
            if (context.Request.RequestType == "POST")
            {
                request.Method = "POST";
                using (var reqstream = request.GetRequestStream())
                {
                    context.Request.InputStream.CopyTo(reqstream);
                }
            }
            var response = request.GetResponse();
            using (var resstream = response.GetResponseStream())
            {
                resstream.CopyTo(context.Response.OutputStream);
            }
        }

        public bool IsReusable { get; private set; }
    }
}
