Asp.Net网站统一处理错误信息

1.创建Global.asax文件

2.在Application_Error里统一处理，可以写入文件，也可以写入SQL。代码如下

            Exception ex = Server.GetLastError().GetBaseException();

            StringBuilder sb = new StringBuilder();

            sb.AppendLine(DateTime.Now.ToString("yyyy.MM.dd HH:mm:ss"));



            //有被注入风险

            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();

            }



            sb.AppendLine("IP地址:" + ip);

            sb.AppendLine("浏览器:" + Request.Browser.Browser.ToString());

            sb.AppendLine("浏览器版本:" + Request.Browser.MajorVersion.ToString());

            sb.AppendLine("操作系统:" + Request.Browser.Platform.ToString());

            sb.AppendLine("错误信息：");

            sb.AppendLine("请求地址：" + Request.Url.ToString());

            sb.AppendLine("错误信息：" + ex.Message);

            sb.AppendLine("错误源：" + ex.Source);

            sb.AppendLine("异常方法：" + ex.TargetSite);

            sb.AppendLine("堆栈信息：" + ex.StackTrace);

            sb.AppendLine("====================================================================================================================");

 

            string logFilePath = Server.MapPath("~/log/");



            if (!Directory.Exists(logFilePath))

            {

                Directory.CreateDirectory(logFilePath);

            }



            File.AppendAllText(logFilePath + DateTime.Now.ToString("yyyy.MM.dd") + ".log", sb.ToString(), Encoding.UTF8);



            Server.ClearError();

            Response.Redirect("myError.htm");
