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

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");

}
