在 ASP.NET MVC 应用程序中记录用户活动

Question

我打算创建基于ActionFilterAttribute过滤器来记录用户活动：

public class LogAttribute : ActionFilterAttribute
{
    public ActionType Type { get; set; }

    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
      // logic for log
    }
}

我想在我的控制器中的 Actions 上使用这个属性。 我想记录用户在我的视图中设置的一些值X,Y,Z以及一些与操作相关的信息。 在这种情况下，我可能必须将这些 X、Y、Z 作为参数发送到我的操作，然后在属性代码中从 ResultExecutedContext 获取这些值。 但是这种方法让我有点困惑，因为我的每个动作都会有多余的参数。

有什么好的方法可以将值从 View 共享到 C# 代码吗？

Answer 1

我可以通过以下方式实现这一目标

创建一个表（名称 - Portal_Logger和D_MASTER ）

接下来，创建一个过滤器，它将跟踪用户的活动，如下所示

LoggerActionFilter.cs

using System;
using System.Web.Mvc;
using System.Net;
using System.Linq;
using System.Net.Sockets;
using MyMvcApplication.Models.Entity;
using MyMvcApplication.Utilities;

namespace MyMvcApplication.Filters
{
    /// <summary>
    /// 
    /// </summary>
    public class LoggerActionFilter : ActionFilterAttribute
    {
        private static TimeZoneInfo INDIAN_ZONE = TimeZoneInfo.FindSystemTimeZoneById("India Standard Time");
        IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            // Stores the Request in an Accessible object
            var request = filterContext.HttpContext.Request;
            var visitCount = Convert.ToInt64(filterContext.HttpContext.Session["LoggerActivityTracking"].ToString());
            // Generate an audit
            Portal_Logger aLogger = new Portal_Logger()
            {
                // Your Logger Identifier     
                LoggerId = Guid.NewGuid(),
                //Logged On User Id
                LogedUserId = Convert.ToInt32(filterContext.HttpContext.Session["LogedUserID"]),
                // The IP Address of the Request
                IPAddress = Convert.ToString(ipHostInfo.AddressList.FirstOrDefault(address => address.AddressFamily == AddressFamily.InterNetwork)),
                //Get the Web Page name(from the URL that was accessed)
                AreaAccessed = UserActivityUtility.GetWebPageName(request.RawUrl == "/"? "/Home/UserLandingPage" : request.RawUrl),
                // Creates our Timestamp
                Timestamp = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, INDIAN_ZONE),
                VisitorSessionId = visitCount
            };
            
            // Stores the Logger in the Database
            using (dbEntities context = new dbEntities())
            {
                if (aLogger.LogedUserId != null)
                {
                    aLogger.LogedUserEmpId = context.D_MASTER
                        .Where(x => x.User_Id == aLogger.LogedUserId)
                        .Select(x => x.Emp_Id).FirstOrDefault();
                    aLogger.LogedUserEmpName = context.D_MASTER
                        .Where(x => x.User_Id == aLogger.LogedUserId)
                        .Select(x => x.Emp_Name).FirstOrDefault();
                    aLogger.AccessedType = aLogger.AreaAccessed.Contains("Report") ? "Report" : "Page";
                }
                context.Portal_Logger.Add(aLogger);
                context.SaveChanges();
            }
            // Finishes executing the Logger as normal 
            base.OnActionExecuting(filterContext);
        }

    }
}

注意： Session["LoggerActivityTracking"]和Session["LogedUserID"]数据我在单独的控制器( AuthController ) Action( ValidateUser ) 中初始化，当用户登录应用程序时执行。

下面我正在使用一个实用程序类，它将从 RawUrl 获取网页的确切名称（例如： /Home/MyController或/Home/MyController1?id=1&name=chandan ）

下面是我的实用程序类

UserActivityUtility.cs

using System;       
namespace MyMvcApplication.Utilities
{
    public static class UserActivityUtility
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="pageName"></param>
        /// <returns></returns>
        public static string GetWebPageName(string pageName)
        {
            string formattedPageName = string.Empty;
            //For All user web pages
            if (pageName.Contains("UserLandingPage"))
            {
                formattedPageName = "Home - App Management";
            }            
            //For Report Web Pages 
            else if (pageName.Contains("AppUtilization"))
            {
                formattedPageName = "Application Utilization Report";
            }           
            else if (pageName.Contains("AlertReport"))
            {
                formattedPageName = "Alert Report";
            }                       
            else
            {
                formattedPageName = pageName;
            }
            return formattedPageName;
        }
    }
}

最后将该属性应用到 Controller Action/s（您要跟踪哪些操作），如下所示

public class HomeController : Controller
{
    [LoggerActionFilter(Order = 1)]
    public ActionResult UserLandingPage()
    {
        return View();
    }
}


public class AdminController : Controller
{
    [LoggerActionFilter(Order = 1)]
    public ActionResult CreateUser()
    {
        return View();
    }
}


public class ReportController : Controller
{
    [LoggerActionFilter(Order = 1)]
    public ActionResult AppUtilization()
    {
        return View();
    }
}

Answer 2

这些值必须在某个时候由用户或代码设置。 但是，您可以使用Session数组来包含这些值。 它们将在登录会话期间保留。

存储到会话

Session["key"] = "data";

后来在代码中

var val = Session["key"]; // val now has a value of "data";

我使用的是一种辅助方法，它使用反射并将模型转储到字典中，这样您就没有问题将值复制到其他地方，所有内容都从一个地方“您的模型”发货

private static Dictionary<string, string> DumpModel(object obt)
        {
            Type type = obt.GetType();
            if (TypeDefinitionIsList(type))
                return null;

            PropertyInfo[] properties = obt.GetType().GetProperties();
            Func<PropertyInfo, string> func = info =>
                                                  {
                                                      if (info.PropertyType.GetInterface(typeof (ICatalogue<>).FullName) != null)
                                                      {
                                                          dynamic propertyValue = info.GetValue(obt, null);
                                                          if (propertyValue != null)
                                                              return string.Format("{{ Id: {0}, Description: {1} }}",
                                                                                   propertyValue.Id,
                                                                                   propertyValue.Description);
                                                          return "null";
                                                      }
                                                      object normalValue = info.GetValue(obt, null);
                                                      if (normalValue == null) return "null";
                                                      return TypeDefinitionIsList(normalValue.GetType()) ? HelpersMessages.NotSupportedList : normalValue.ToString();
                                                  };

            return properties.ToDictionary(x => "model-"+x.Name, func);
        }

您可以在过滤器属性中使用它

var request = filterContext.HttpContext.Request;
object model = filterContext.Controller.ViewData.Model;

你可以使用类似的东西

 DumpModel(model);    

使用这些值来记录你需要的任何人，我希望这会有所帮助
