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}\r\n消息内容：{filtercontext.exception.message}\r\n引发异常的方法：{filtercontext.exception.targetsite}\r\n引发异常的对象：{filtercontext.exception.source}\r\n异常目录：{filtercontext.routedata.getrequiredstring("controller")}\r\n异常方法：{filtercontext.routedata.getrequiredstring("action")}\r\n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">
    <div class="row text-center">
        <br/>
        <br />

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

                var exception = viewdata.model;
                var statuscode = exception == null ? 404 : 500;
                response.statuscode = statuscode;
                if (statuscode == 404)
                {
                    <h1>404 page not found!</h1>
                    <p>没有找到该网页!</p>
