ASP.NET MVC 全局異常

先新建一個過濾器ExceptionHandleErrorAttribute.cs

內容如下：

 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     /// 異常捕獲（業務邏輯層，UI層）
11     /// </summary>
12     public class ExceptionHandleErrorAttribute : HandleErrorAttribute
13     {
14         /// <summary>
15         /// 錯誤攔截
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                 $"消息類型：{filterContext.Exception.GetType().Name}\r\n消息內容：{filterContext.Exception.Message}\r\n引發異常的方法：{filterContext.Exception.TargetSite}\r\n引發異常的對象：{filterContext.Exception.Source}\r\n異常目錄：{filterContext.RouteData.GetRequiredString("controller")}\r\n異常方法：{filterContext.RouteData.GetRequiredString("action")}\r\n錯誤詳細記錄：{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 }

然後在FilterConfig添加

Global.asax全局下添加

最後處理下ajax錯誤處理和伺服器錯誤呈現形式
