asp.net mvc ,asp.net mvc api 中使用全局過濾器進行異常捕獲記錄

MVC下的全局異常過濾器注冊方式如下：標紅為asp.net mvc ,asp.net mvc api  注冊全局異常過濾器的不同之處

using SuperManCore;
using System.Web;
using System.Web.Mvc;

namespace SuperMan
{
    public class FilterConfig
    {
        /// <summary>
        /// 注冊全局過濾器 add by caoheyang 20150205
        /// </summary>
        /// <param name="filters"></param>
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new WebHandleErrorAttribute(), 1);
            filters.Add(new HandleErrorAttribute(), 2);
        }
    }


    /// <summary>
    /// 自定義異常處理類  add by caoheyang 20150205
    /// </summary>
    public class WebHandleErrorAttribute : HandleErrorAttribute
    {
        /// <summary>
        /// 重寫異常處理方法 add by caoheyang 20150205   需要將該特性標注於各個controller上。
        /// </summary>
        /// <param name="filterContext">上下文對象  該類繼承於ControllerContext</param>
        public override void OnException(ExceptionContext filterContext)
        {
            LogHelper.LogWriterFromFilter(filterContext.Exception);
        }
    }
}

MVC API下的注冊方式如下：
在WebApiConfig.cs文件下加入標紅代碼

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web.Http;
using Microsoft.Owin.Security.OAuth;
using Newtonsoft.Json.Serialization;

namespace SuperManWebApi
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API 配置和服務
            // 將 Web API 配置為僅使用不記名令牌身份驗證。
            config.SuppressDefaultHostAuthentication();
            config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
      config.Filters.Add(new ApiHandleErrorAttribute());  //注冊全局異常過濾器 add by caoheyang 20150206     不需要將該特性標注於各個controller上
            // Web API 路由
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",                
                routeTemplate: "{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

 /// <summary>
    /// 自定義異常處理類  add by caoheyang 20150205   不需要將該特性標注於各個controller上。 /// </summary>
    public class ApiHandleErrorAttribute : ExceptionFilterAttribute
    {
        /// <summary>
        /// 重寫異常處理方法 add by caoheyang 20150205
        /// </summary>
        /// <param name="filterContext">上下文對象</param>
        public override void OnException(HttpActionExecutedContext filterContext)
        {
            LogHelper.LogWriterFromFilter(filterContext.Exception);
        }
     }

另外附LogHelper源碼:

public class LogHelper
    {
       public static Logger logger = LogManager.GetLogger("SuperManCore.LogHelper");
  
       /// <summary>
       /// 備注日志

       /// <param name="rmark">描述操作</param>
       public new static void LogWriter(string rmark="",object dec=null)
       {
           try
           {
               string logstr = "\r\n-----------------start----------------------\r\n";
               MethodBase m = new StackTrace().GetFrame(1).GetMethod();
               ParameterInfo[] pm = m.GetParameters();
               string classname = m.DeclaringType.ToString();
               string propertyName = m.Name;
               logstr = logstr + "備注:" + rmark + "\r\n";

               for (int i = 0; i < pm.Length; i++)
               {

               }
               JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
               logstr = logstr + "函數參數值:" + jsonSerializer.Serialize(dec) + "\r\n";
               logstr += "--------------------end---------------------\r\n";
               //寫日志
               logger.Info(logstr);
           }
           catch (Exception)
           {

               throw;
           }

       }
