我通过godaddy.com托管一个网站，下面是链接:

这是我的网。配置文件:

我得到运行时错误:

运行时错误

描述:应用程序错误发生在服务器上。当前的自定义错误设置应用程序防止的细节查看应用程序时出现错误远程(出于安全原因)。它但是，可以被浏览器查看吗在本地服务器上运行。

我还设置了customErrors mode = "off"。这里出了什么问题?我使用的是Visual Studio 2010 4.0框架。谢谢!

Answer 1

如果您的主机启用了customErrors，您可以考虑自己捕获并记录异常，以便您可以看到发生了什么。

有几个选项。首先，试试Elmah

第二，你可以使用你的日志库(我喜欢NLog，但任何一个都可以)，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，这都是一个很好的特性，即使您能够关闭customErrors。

Answer 2

服务器的machine.config或applicationHost.config可能会覆盖您的web.config设置。不幸的是，如果是这种情况，除了联系GoDaddy的支持热线之外，您无能为力。

Answer 3

customErrors mode value Off是大小写敏感的我认为。请检查第一个字符是否大写

Answer 4

您可以在您的全局中捕获错误。和发送电子邮件的例外。

在Global.asax.cs:

 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My 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}rnURL: {1}rn=====================rn{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====== rn{0}", ExceptionHandler.AddExceptionText(ex.InnerException));
            }
            string message = string.Format("Message: {0}rnSource: {1}rnStack:rn{2}rnrn{3}", ex.Message, ex.Source, ex.StackTrace, innermessage);
            return message;
        }
    }
