Global.asax的Application_Error实现错误记录/错误日志的代码

复制代码 代码如下:

void Application_Error(object sender, EventArgs e)
{
// 在出现未处理的错误时运行的代码
Exception ex = Server.GetLastError().GetBaseException();
StringBuilder str = new StringBuilder();
str.Append("/r/n" + DateTime.Now.ToString("yyyy.MM.dd HH:mm:ss"));
str.Append("/r/n.客户信息：");


string ip = "";
if (Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR") != null)
{
ip = Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR").ToString().Trim();
}
else
{
ip = Request.ServerVariables.Get("Remote_Addr").ToString().Trim();
}
str.Append("/r/n/tIp:" + ip);
str.Append("/r/n/t浏览器:" + Request.Browser.Browser.ToString());
str.Append("/r/n/t浏览器版本:" + Request.Browser.MajorVersion.ToString());
str.Append("/r/n/t操作系统:" + Request.Browser.Platform.ToString());
str.Append("/r/n.错误信息：");
str.Append("/r/n/t页面：" + Request.Url.ToString());
str.Append("/r/n/t错误信息：" + ex.Message);
str.Append("/r/n/t错误源：" + ex.Source);
str.Append("/r/n/t异常方法：" + ex.TargetSite);
str.Append("/r/n/t堆栈信息：" + ex.StackTrace);
str.Append("/r/n--------------------------------------------------------------------------------------------------");
//创建路径
string upLoadPath = Server.MapPath("~/log/");
if (!System.IO.Directory.Exists(upLoadPath))
{
System.IO.Directory.CreateDirectory(upLoadPath);
}
//创建文件 写入错误
System.IO.File.AppendAllText(upLoadPath + DateTime.Now.ToString("yyyy.MM.dd") + ".log", str.ToString(), System.Text.Encoding.UTF8);
//处理完及时清理异常
Server.ClearError();
//跳转至出错页面
Response.Redirect("~/error.html");
}
