Question

我已经申请记录当前PC用户访问过的所有网站。这不是恶意用途。我正在为我的员工监控软件制作此功能，该软件将根据适当的法律获得许可。

来自主要观点，每当我从任何浏览器（例如IE）获取URL时。我只获取所有打开的标签的URL。我无法获得IE7 +的任何标签句柄，因此我无法维护一个标签列表，我已经为相同的标签记录了URL。下面是我的代码（首先看一下评论代码）：

我提供了有关此主题的解决方案：How to write a standalone URL logger for Windows?

我使用过Java，但你可以使用C＃来做同样的事情。我几乎可以肯定C＃有很多好的libpcap包装器。

有一个名为pcapDotNet的项目，您可以使用它。

调整一个例子：

using System;
using System.Collections.Generic;
using PcapDotNet.Core;
using PcapDotNet.Packets;
using PcapDotNet.Packets.IpV4;
using PcapDotNet.Packets.Transport;

namespace InterpretingThePackets
{
    class Program
    {
        static void Main(string[] args)
        {
            // Retrieve the device list from the local machine
            IList<LivePacketDevice> allDevices = LivePacketDevice.AllLocalMachine;

            if (allDevices.Count == 0)
            {
                Console.WriteLine("No interfaces found! Make sure WinPcap is installed.");
                return;
            }

            // Print the list
            for (int i = 0; i != allDevices.Count; ++i)
            {
                LivePacketDevice device = allDevices[i];
                Console.Write((i + 1) + ". " + device.Name);
                if (device.Description != null)
                    Console.WriteLine(" (" + device.Description + ")");
                else
                    Console.WriteLine(" (No description available)");
            }

            int deviceIndex = 0;
            do
            {
                Console.WriteLine("Enter the interface number (1-" + allDevices.Count + "):");
                string deviceIndexString = Console.ReadLine();
                if (!int.TryParse(deviceIndexString, out deviceIndex) ||
                    deviceIndex < 1 || deviceIndex > allDevices.Count)
                {
                    deviceIndex = 0;
                }
            } while (deviceIndex == 0);

            // Take the selected adapter
            PacketDevice selectedDevice = allDevices[deviceIndex - 1];

            // Open the device
            using (PacketCommunicator communicator = 
                selectedDevice.Open(65536,                                  // portion of the packet to capture
                                                                            // 65536 guarantees that the whole packet will be captured on all the link layers
                                    PacketDeviceOpenAttributes.Promiscuous, // promiscuous mode
                                    1000))                                  // read timeout
            {
                // Check the link layer. We support only Ethernet for simplicity.
                if (communicator.DataLink.Kind != DataLinkKind.Ethernet)
                {
                    Console.WriteLine("This program works only on Ethernet networks.");
                    return;
                }

                // Compile the filter
                using (BerkeleyPacketFilter filter = communicator.CreateFilter("ip and tcp"))
                {
                    // Set the filter
                    communicator.SetFilter(filter);
                }

                Console.WriteLine("Listening on " + selectedDevice.Description + "...");

                // start the capture
                communicator.ReceivePackets(0, PacketHandler);
            }
        }

        // Callback function invoked by libpcap for every incoming packet
        private static void PacketHandler(Packet packet)
        {
            // print timestamp and length of the packet
            Console.WriteLine(packet.Timestamp.ToString("yyyy-MM-dd hh:mm:ss.fff") + " length:" + packet.Length);

            IpV4Datagram ip = packet.Ethernet.IpV4;

            //Do your magic here using HttpRequestDatagram
        }
    }
}
