我通过 godaddy.com 托管一个网站,这是链接:

这是我的 web.config 文件:

我收到运行时错误:

运行时错误

说明:服务器上发生应用程序错误。此应用程序的当前自定义错误设置阻止远程查看应用程序错误的详细信息(出于安全原因)。但是,它可以被本地服务器机器上运行的浏览器查看。

我还设置了 customErrors mode = "off"。这里有什么问题?我正在使用带有 4.0 框架的 Visual Studio 2010。谢谢!

如果您的主机已启用customErrors,您可能会考虑自己捕获并记录异常,以便查看发生了什么。

有几个选择。首先,尝试Elmah

其次,您可以使用您的日志库(我喜欢 NLog,但任何都可以),并在 Global.asax.cs 中捕获 Application_Error 事件。

protected void Application_Error(object sender, EventArgs e)
        {
            //first, find the exception.  any exceptions caught here will be wrapped
            //by an httpunhandledexception, which doesn't realy help us, so we'll
            //try to get the inner exception
            Exception exception = Server.GetLastError();
            if (exception.GetType() == typeof(HttpUnhandledException) && exception.InnerException != null)
            {
                exception = exception.InnerException;
            }

            //get a logger from the container
            ILogger logger = ObjectFactory.GetInstance<ILogger>();
            //log it
            logger.FatalException("Global Exception", exception);
        }

无论如何,这是一个很好的功能,即使您能够关闭 customErrors。

服务器的machine.configapplicationHost.config可能会覆盖您的web.config设置。不幸的是,如果是这种情况,您真的无能为力,只能联系 GoDaddy 的支持热线。

我认为customErrors modeOff区分大小写。请检查您的第一个字符是否大写。

您可以在 Global.asax 中捕获错误并发送带有异常的电子邮件。

在 Global.asax.cs 中:

 void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs
            Exception ex = Server.GetLastError();
            ExceptionHandler.SendExceptionEmail(ex, "Unhandled", this.User.Identity.Name, this.Request.RawUrl);
            Response.Redirect("~/ErrorPage.aspx"); // So the user does not see the ASP.net Error Message
        }

我在我的 ExceptionHandler 类中的方法:

class ExceptionHandler
    {
        public static void SendExceptionEmail(Exception ex, string ErrorLocation, string UserName, string url)
        {
            SmtpClient mailclient = new SmtpClient();
            try
            {
                string errorMessage = string.Format("User: {0}\r\nURL: {1}\r\n=====================\r\n{2}", UserName, url, AddExceptionText(ex));
                mailclient.Send(ConfigurationManager.AppSettings["ErrorFromEmailAddress"],
                                ConfigurationManager.AppSettings["ErrorEmailAddress"],
                                ConfigurationManager.AppSettings["ErrorEmailSubject"] + " = " + ErrorLocation,
                                errorMessage);
            }
            catch { }
            finally { mailclient.Dispose(); }
        }

        private static string AddExceptionText(Exception ex)
        {
            string innermessage = string.Empty;
            if (ex.InnerException != null)
            {
                innermessage = string.Format("=======InnerException====== \r\n{0}", ExceptionHandler.AddExceptionText(ex.InnerException));
            }
            string message = string.Format("Message: {0}\r\nSource: {1}\r\nStack:\r\n{2}\r\n\r\n{3}", ex.Message, ex.Source, ex.StackTrace, innermessage);
            return message;
        }
    }
