[ASP.NET] 基于.Net Remoting 的网站访问监控模块

监控公司局域网的网站访问情况。
项目1：
新建类MonitorHttpModule.cs

namespace HouseProgram.HttpModule
{
    public class MonitorHttpModule :IHttpModule
    {
        public void Init(HttpApplication application)
        {
            if (ChannelServices.RegisteredChannels.Length > 0)
            {
            }
            else
            {
                ChannelServices.RegisterChannel(new TcpClientChannel(), false);
            }           

            application.BeginRequest += new EventHandler(application_BeginRequest);
        }

        void application_BeginRequest(object sender, EventArgs e)
        {
            try
            {
                HttpContext context = ((HttpApplication)sender).Context;
                MonitorClass obj = (MonitorClass)Activator.GetObject(typeof(MonitorClass), "tcp://sz389:8085/HouseProgramMonitor");
                if (obj == null)
                {
                }
                else
                {
                    StringBuilder sb = new StringBuilder();
                    sb.AppendLine(String.Format("Time:[ {0} ]  IP:[ {1} ]  Type:[ {2} ]", DateTime.Now.ToString(), context.Request.UserHostAddress, context.Request.RequestType));
                    if (!String.IsNullOrEmpty(context.Request.ContentType))
                    {
                        sb.AppendLine(context.Request.ContentType);
                    }
                    if (!String.IsNullOrEmpty(context.Request.Form.ToString()))
                    {
                        sb.AppendLine(context.Request.Form.ToString().Replace("&","\r\n"));
                    }
                    sb.AppendLine(context.Request.Url.ToString());
                    obj.RecordInfo(sb.ToString(), context.Request.RequestType);
                }
            }
            catch
            {
            }
        }

        public void Dispose()
        {
        }
    }
}

生成dll，在站点的Web.config 文件中加入以下节点：

<system.web>
    <httpModules>
        <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
        <add name="MonitorHttpModule" type="HouseProgram.HttpModule.MonitorHttpModule"/>
    </httpModules>
</system.web>

项目2：
新建类MonitorClass.cs

public class MonitorClass : MarshalByRefObject
    {
        public MonitorClass()
        {
            //Console.WriteLine(String.Format("Client Constructor Called  DateTime: [ {0} ]", DateTime.Now.ToString()));
        }

        ~MonitorClass()
        {
            //Console.WriteLine(String.Format("Client Destructor Called  DateTime: [ {0} ]", DateTime.Now.ToString()));
        }

        public delegate void RecordInfoHandler(string msg, string requestType);
        public static event RecordInfoHandler OnRecordInfoEvent;

        public void RecordInfo(string msg, string requestType)
        {
            if (OnRecordInfoEvent != null)
            {
                OnRecordInfoEvent(msg, requestType);
            }
        }
    }

项目3：
新建Console 项目

namespace HouseProgram.RemotingServer
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpServerChannel channel = new TcpServerChannel(8085);

            ChannelServices.RegisterChannel(channel, false);

            RemotingConfiguration.RegisterWellKnownServiceType(typeof(MonitorClass), "HouseProgramMonitor", WellKnownObjectMode.SingleCall);
            Console.BufferHeight = 30000;
            MonitorClass.OnRecordInfoEvent += new MonitorClass.RecordInfoHandler(MonitorClass_OnRecordInfoEvent);            
            Console.WriteLine("Press Enter to exit.");
            Console.ReadLine(); 
        }
        static void MonitorClass_OnRecordInfoEvent(string msg, string requestType)
        {
            switch (requestType)
            {
                case "POST":
                    Console.ForegroundColor = ConsoleColor.Yellow;
                    Console.WriteLine(msg);
                    break;
                case "GET":
                    Console.ForegroundColor = ConsoleColor.DarkGreen;
                    Console.WriteLine(msg);
                    break;
                default:
                    Console.ForegroundColor = ConsoleColor.Cyan;
                    Console.WriteLine(msg);
                    break;
            }
            
        }
    }
}
