超级简单:一步一步教你实现简单的自定义错误跟踪

2/1/2010来源:ASP技巧人气:4412

一、设计xml,应该包含下面信息:

    1、Datetime:  发生错误/异常的日期和时间
    2、File name: 发生错误/异常的文件名
    3、Class name : 发生错误/异常的类名
    4、Methodname: 发生错误/异常的方法名
    5、Errormethod :  包含错误代码的函数名字
    6、Message :错误/异常的信息
    7、Error details: 错误/异常详情
    8、ip : 客户端IP地址
    9、URL : 发生错误的URL

DemoXML:

DemoXML
<?xml version="1.0" encoding="utf-8"?>
<errorlog>
  <error>
    <datetime>datetime</datetime>
    <filename>filename</filename>
    <classname>classname</classname>
    <methodname>methodname</methodname>
    <errormethod>errormethod</errormethod>
    <messsage>ErrorMessage</messsage>
    <errordetails>Details goes here</errordetails>
    <IP>IP adress</IP>
    <url>URL</url>
  </error>
</errorlog>
二、设计错误处理类:errorHandler.cs,里面的WriteError方法需要Exception和FileName两个参数:

errorHandler.cs
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.Reflection;
using System.Diagnostics;
namespace code_center
{
    public class errorHandler
    {
        string _strErrorMessage, _strDetails, _strClassName, _strMethodName;
        DateTime _dtOccuranceTime = new DateTime();
        public errorHandler()
        {
        }
        public errorHandler(DateTime time, string className, string methodName,
            string errorMessage, string details)
        {
            _dtOccuranceTime = time;
            _strClassName = className;
            _strDetails = details;
            _strErrorMessage = errorMessage;
            _strMethodName = methodName;
        }
        public static void WriteError(Exception ex)
        {
            WriteError(ex, "");
        }
        public static void WriteError(Exception ex, string fileName)
        {
            XmlDocument doc = new XmlDocument();
            string strRootPath =
           System.Configuration.ConfigurationManager.AppSettings["logfilepath"].ToString();
            string xmlPath = System.Web.HttpContext.Current.Server.MapPath(strRootPath);
            doc.Load(@xmlPath);
            XmlNode newXMLNode, oldXMLNode;
            oldXMLNode = doc.ChildNodes[1].ChildNodes[0];
            newXMLNode = oldXMLNode.CloneNode(true);
            StackTrace stackTrace = new StackTrace();
            StackFrame stackFrame = stackTrace.GetFrame(1);
            MethodBase methodBase = stackFrame.GetMethod();
            newXMLNode.ChildNodes[0].InnerText = DateTime.Now.ToString();
            newXMLNode.ChildNodes[1].InnerText = fileName;
            newXMLNode.ChildNodes[2].InnerText = methodBase.DeclaringType.FullName;
            newXMLNode.ChildNodes[3].InnerText = methodBase.Name;
            newXMLNode.ChildNodes[4].InnerText = ex.TargetSite.Name;
            newXMLNode.ChildNodes[5].InnerText = ex.Message;
            newXMLNode.ChildNodes[6].InnerText = ex.StackTrace;
            newXMLNode.ChildNodes[7].InnerText = System.Web.HttpContext.Current.Request.UserHostAddress;
            newXMLNode.ChildNodes[8].InnerText = System.Web.HttpContext.Current.Request.Url.OriginalString;
            doc.ChildNodes[1].AppendChild(newXMLNode);
            doc.Save(@xmlPath);
            doc.RemoveAll();
        }
    }
}
三、 在Web.config加入:

    <appSettings>
        <add key="logfilepath" value="~/errorHandling/errorlog.xml"/>
    </appSettings>
四、测试:在你的网站中加入两段测试代码

1、在Page_Load:

Page_Load
    public partial class _Default : System.Web.UI.Page
    {
        PRotected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                throw new Exception("Custom error");
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
                kirin.errorHandler.WriteError(ex, "Default.aspx.cs");
            }
        }
    }
2、在application_Error中加入:

    void Application_Error(object sender, EventArgs e)
    {
        code_center.errorHandler.WriteError(Server.GetLastError().GetBaseException(),
            "Global.asax");
    }
3、Page_Load异常的结果:

errorXML
  <error>
    <datetime>2010-1-29 9:29:24</datetime>
    <filename>Default.aspx.vb</filename>
    <classname>kirin._Default</classname>
    <methodname>Page_Load</methodname>
    <errormethod>Page_Load</errormethod>
    <messsage>Custom error</messsage>
    <errordetails>   在 kirin._Default.Page_Load(Object sender, EventArgs e) 位置 C:\Demo\kirin_code_center\kirin\Default.aspx.cs:行号 16</errordetails>
    <IP>127.0.0.1</IP>
    <url>http://localhost:2192/default.aspx</url>
</error>
