MVC下的全局异常过滤器注册方式如下:标红为asp.net mvc ,asp.net mvc api 注册全局异常过滤器的不同之处
using SuperManCore; using System.Web; using System.Web.Mvc; namespace SuperMan { public class FilterConfig { /// <summary> /// 注册全局过滤器 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> /// 自定义异常处理类 add by caoheyang 20150205 /// </summary> public class WebHandleErrorAttribute : HandleErrorAttribute { /// <summary> /// 重写异常处理方法 add by caoheyang 20150205 需要将该特性标注于各个controller上。 /// </summary> /// <param name="filterContext">上下文对象 该类继承于ControllerContext</param> public override void OnException(ExceptionContext filterContext) { LogHelper.LogWriterFromFilter(filterContext.Exception); } } }
MVC API下的注册方式如下:
在WebApiConfig.cs文件下加入标红代码
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 配置和服务 // 将 Web API 配置为仅使用不记名令牌身份验证。 config.SuppressDefaultHostAuthentication(); config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType)); config.Filters.Add(new ApiHandleErrorAttribute()); //注册全局异常过滤器 add by caoheyang 20150206 不需要将该特性标注于各个controller上 // Web API 路由 config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "{controller}/{action}/{id}", defaults: new { id = RouteParameter.Optional } ); } } } /// <summary> /// 自定义异常处理类 add by caoheyang 20150205 不需要将该特性标注于各个controller上。 /// </summary> public class ApiHandleErrorAttribute : ExceptionFilterAttribute { /// <summary> /// 重写异常处理方法 add by caoheyang 20150205 /// </summary> /// <param name="filterContext">上下文对象 该类继承于ControllerContext</param> public override void OnException(HttpActionExecutedContext filterContext) { LogHelper.LogWriterFromFilter(filterContext.Exception); } }
另外附LogHelper源码:
public class LogHelper { public static Logger logger = LogManager.GetLogger("SuperManCore.LogHelper"); /// <summary> /// 备注日志 /// </summary> /// <param name="dec">需要捕获的参数(必须为属性类)</param> /// <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 + "备注:" + rmark + "\r\n"; //写类名 logstr = logstr + "函数类名:" + classname + "\r\n"; //写函数方法 logstr = logstr + "函数名称为:" + propertyName + "\r\n"; for (int i = 0; i < pm.Length; i++) { logstr = logstr + "函数的参数有:" + pm[i].Name.ToString() + "\r\n"; } JavaScriptSerializer jsonSerializer = new JavaScriptSerializer(); logstr = logstr + "函数参数值:" + jsonSerializer.Serialize(dec) + "\r\n"; logstr += "--------------------end---------------------\r\n"; //写日志 logger.Info(logstr); } catch (Exception) { throw; } } /// <summary> /// 异常捕获日志 /// </summary> /// <param name="ex">异常对象(必须为属性类)</param> /// <param name="rmark">操作简要描述</param> public new static void LogWriter(Exception ex, string rmark="") { 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 + "备注:" + rmark + "\r\n"; //写类名 logstr = logstr + "函数类名:" + classname + "\r\n"; //写函数方法 logstr = logstr + "函数名称为:" + propertyName + "\r\n"; for (int i = 0; i < pm.Length; i++) { logstr = logstr + "函数的参数有:" + pm[i].Name.ToString() + "\r\n"; } logstr = logstr + "函数异常:" + ex.ToString() + "\r\n"; logstr += "--------------------end---------------------\r\n"; //写日志 logger.Info(logstr); } catch (Exception) { throw; } } /// <summary> /// 带参数 异常的日志 /// </summary> /// <param name="dec">异常参数对象(必须为属性类)</param> /// <param name="ex">日志异常对象</param> public new static void LogWriter(object dec, Exception ex) { 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; //写类名 logstr = logstr + "函数类名:" + classname + "\r\n"; //写函数方法 logstr = logstr + "函数名称为:" + propertyName + "\r\n"; for (int i = 0; i < pm.Length; i++) { logstr = logstr + "函数的参数有:" + pm[i].Name.ToString() + "\r\n"; } JavaScriptSerializer jsonSerializer = new JavaScriptSerializer(); logstr = logstr + "函数参数值:" + jsonSerializer.Serialize(dec) + "\r\n"; logstr = logstr + "函数异常:" + ex.ToString() + "\r\n"; logstr += "--------------------end---------------------\r\n"; //写日志 logger.Info(logstr); } catch (Exception) { throw; } } /// <summary> /// 带参数 描述 异常日志捕获 /// </summary> /// <param name="dec">所要捕获的参数(必须为属性类)</param> /// <param name="ex">异常对象</param> /// <param name="rmark">描述</param> public new static void LogWriter(object dec, Exception ex, string rmark) { 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; //写备注 logstr = logstr + "备注:" + rmark + "\r\n"; //写类名 logstr = logstr + "函数类名:" + classname + "\r\n"; //写函数方法 logstr = logstr + "函数名称为:" + propertyName + "\r\n"; for (int i = 0; i < pm.Length; i++) { logstr = logstr + "函数的参数有:" + pm[i].Name.ToString() + "\r\n"; } JavaScriptSerializer jsonSerializer = new JavaScriptSerializer(); logstr = logstr + "函数参数值:" + jsonSerializer.Serialize(dec) + "\r\n"; logstr = logstr + "函数异常:" + ex.ToString() + "\r\n"; logstr += "--------------------end---------------------\r\n"; //写日志 logger.Info(logstr); } catch (Exception) { throw; } } /// <summary> /// 捕获全局异常 /// </summary> /// <param name="error"></param> public new static void LogWriterFromFilter(Exception error) { try { string logstr = "\r\n-----------------start----------------------\r\n"; //异常发生地址 logstr = logstr + "异常发生地址:" + HttpContext.Current.Request.Url.AbsoluteUri.ToString() + "\r\n"; logstr = logstr + "请求类型:" + HttpContext.Current.Request.RequestType.ToString() + "\r\n"; logstr = logstr + "异常:" + error.ToString() + "\r\n"; logstr += "--------------------end---------------------\r\n"; //发送邮件 if (ConfigSettings.Instance.IsSendMail == "true") { string emailToAddress = ConfigSettings.Instance.EmailToAdress; EmailHelper.SendEmailTo(logstr, emailToAddress); } //写日志 logger.Info(logstr); } catch (Exception) { throw; } } }
注:LogHelper所在类库需要引用NLog.dll文件。
