利用Global.asax的Application_Error实现错误记录

错误日志
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(" " + DateTime.Now.ToString("yyyy.MM.dd HH:mm:ss"));
str.Append(" .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(" Ip:" + ip);
str.Append(" 浏览器:" + Request.Browser.Browser.ToString());
str.Append(" 浏览器版本:" + Request.Browser.MajorVersion.ToString());
str.Append(" 操作系统:" + Request.Browser.Platform.ToString());
str.Append(" .错误信息:");
str.Append(" 页面:" + Request.Url.ToString());
str.Append(" 错误信息:" + ex.Message);
str.Append(" 错误源:" + ex.Source);
str.Append(" 异常方法:" + ex.TargetSite);
str.Append(" 堆栈信息:" + ex.StackTrace);
str.Append(" --------------------------------------------------------------------------------------------------");
//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");
}
