• ASP.NET MVC 全局异常


    先新建一个过滤器ExceptionHandleErrorAttribute.cs

    内容如下:

     1 using System;
     2 using System.Net;
     3 using System.Web;
     4 using System.Web.Mvc;
     5 using ABBPMP.Utility.NLogHelper.Static;
     6 
     7 namespace ABBPMP.Filter
     8 {
     9     /// <summary>
    10     /// 异常捕获(业务逻辑层,UI层)
    11     /// </summary>
    12     public class ExceptionHandleErrorAttribute : HandleErrorAttribute
    13     {
    14         /// <summary>
    15         /// 错误拦截
    16         /// </summary>
    17         /// <param name="filterContext"></param>
    18         public override void OnException(ExceptionContext filterContext)
    19         {
    20 
    21             if (filterContext.ExceptionHandled)
    22             {
    23                 return;
    24             }
    25 
    26 
    27 
    28             string message =
    29                 $"消息类型:{filterContext.Exception.GetType().Name}
    消息内容:{filterContext.Exception.Message}
    引发异常的方法:{filterContext.Exception.TargetSite}
    引发异常的对象:{filterContext.Exception.Source}
    异常目录:{filterContext.RouteData.GetRequiredString("controller")}
    异常方法:{filterContext.RouteData.GetRequiredString("action")}
    错误详细记录:{filterContext.Exception.StackTrace}";
    30             NLogHandler.Instance.Error(message);
    31             if (!filterContext.HttpContext.Request.IsAjaxRequest())
    32             {
    33                 filterContext.Controller.ViewData.Model = filterContext.Exception;
    34                 filterContext.Result = new ViewResult
    35                 {
    36                     ViewName = "~/Views/Error/Error.cshtml",
    37                     ViewData = filterContext.Controller.ViewData
    38                 };
    39             }
    40             filterContext.Result = AjaxError(filterContext.Exception.Message, filterContext);
    41 
    42 
    43 
    44 
    45             filterContext.ExceptionHandled = true;
    46         }
    47         /// <summary>
    48         /// Ajaxes the error.
    49         /// </summary>
    50         /// <param name="message">The message.</param>
    51         /// <param name="filterContext">The filter context.</param>
    52         /// <returns>JsonResult</returns>
    53         protected JsonResult AjaxError(string message, ExceptionContext filterContext)
    54         {
    55 
    56             //If message is null or empty, then fill with generic message
    57             if (String.IsNullOrEmpty(message))
    58                 message = "Something went wrong while processing your request. Please refresh the page and try again.";
    59             //Set the response status code to 500
    60             filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
    61             //Needed for IIS7.0
    62             filterContext.HttpContext.Response.TrySkipIisCustomErrors = true;
    63             return new JsonResult
    64             {
    65                 //can extend more properties 
    66                 Data = new AjaxExceptionModel() { ErrorMessage = message },
    67                 ContentEncoding = System.Text.Encoding.UTF8,
    68                 JsonRequestBehavior = JsonRequestBehavior.DenyGet
    69 
    70             };
    71 
    72         }
    73         /// <summary>
    74         /// AjaxExceptionModel
    75         /// </summary>
    76         public class AjaxExceptionModel
    77         {
    78             /// <summary>
    79             /// Gets or sets the error message.
    80             /// </summary>
    81             /// <value>
    82             /// The error message.
    83             /// </value>
    84             public string ErrorMessage { get; set; }
    85 
    86         }
    87 
    88     }
    89 }
    View Code

    然后在FilterConfig添加

    Global.asax全局下添加

    最后处理下ajax错误处理和服务器错误呈现形式

    @{
        ViewBag.Title = "General Site Error";
        Layout = "~/Views/Shared/_Layout.cshtml";
    }
    <div class="container">

            <br />
            <div class="col-md-6 col-md-offset-3 text-center">

                    var statusCode = exception == null ? 404 : 500;
                    Response.StatusCode = statusCode;
                    if (statusCode == 404)
