重定向URI不能包含换行符.(查询字符串)

Question

我收到此错误重定向URI不能包含换行符.当运行下面的代码.工作MVC 4.她是我的工作代码.

 protected void Application_Error(Object sender, System.EventArgs e)
            {
                System.Web.HttpContext context = HttpContext.Current;
                System.Exception exception = Context.Server.GetLastError();
                var stackTraceExcep = new StackTrace(exception, true); // create the stack trace
                var stackTrace = stackTraceExcep.GetFrames()         // get the frames
                              .Select(frame => new
                              {                   // get the info
                                  FileName = frame.GetFileName(),
                                  LineNumber = frame.GetFileLineNumber(),
                                  ColumnNumber = frame.GetFileColumnNumber(),
                                  Method = frame.GetMethod(),
                                  Class = frame.GetMethod().DeclaringType,
                              }).FirstOrDefault();


                string FileName = stackTrace.FileName;
                string LineNumber = stackTrace.LineNumber;
                string ColumnNumber = stackTrace.ColumnNumber;
                string MethodName = stackTrace.Method.Name;
                string ClassName = stackTrace.Class.Name;
                if (!string.IsNullOrEmpty(exception.Message))
                {
                    Response.Redirect(String.Format("~/Error/{0}/?errorMessage={1},FileName={2},LineNumber={3},ColumnNumber={4},MethodName={5},ClassName={6}", "App_Error", exception.Message, FileName, LineNumber, ColumnNumber, MethodName, ClassName));//I got this error in this line 
                }
                context.Server.ClearError();
            }

什么问题 ？我们怎么解决这个问题？我已经搜索并尝试了谷歌并获得了一些堆栈溢出答案.但什么都没有帮助我.

我现在在做什么？

我的控制器动作方法

[HttpGet]
        public ActionResult App_Error(string errorMessage, string fileName, string lineNumber, string columnNumber, string methodName, string className)
        {
            string errorNumber = Convert.ToString(errorRepository.AddError(errorMessage, fileName, Convert.ToInt32(lineNumber), Convert.ToInt32(columnNumber), methodName, className));
            ViewData["message"] = "An error has occurred in the application . The error number is : " + errorNumber;
            return View();
        }

Answer 1

您需要使用HttpUtility或UrlHelper对您的异常消息进行URLEncode编码

HttpUtility.UrlEncode(exception.Message)

更改您的重定向行,如下所示

Response.Redirect(String.Format("~/Error/{0}/?errorMessage={1},FileName={2},LineNumber={3},ColumnNumber={4},MethodName={5},ClassName={6}", "App_Error", HttpUtility.UrlEncode(exception.Message), FileName, LineNumber, ColumnNumber, MethodName, ClassName));

Answer 2

试试这个代码

我认为 。您的文件名为 null 或 Url 字段。所以它很困惑并显示错误。现在我刚刚更改了您的代码，请参阅粗体行。

编辑：

并且您的查询字符串格式错误。Please Change ,( comma) to & (and)

 protected void Application_Error(Object sender, System.EventArgs e)
        {
            System.Web.HttpContext context = HttpContext.Current;
            System.Exception exception = Context.Server.GetLastError();
            var stackTraceExcep = new StackTrace(exception, true); 
            var stackTrace = stackTraceExcep.GetFrames()         
                          .Select(frame => new
                          {                   // get the info
                              FileName = frame.GetFileName(),
                              LineNumber = frame.GetFileLineNumber(),
                              ColumnNumber = frame.GetFileColumnNumber(),
                              Method = frame.GetMethod(),
                              Class = frame.GetMethod().DeclaringType,
                          }).FirstOrDefault();


            **string FileName = !string.IsNullOrEmpty(stackTrace.FileName) ? Server.UrlEncode(stackTrace.FileName) : "";**
            string LineNumber = stackTrace.LineNumber.ToString();
            string ColumnNumber = stackTrace.ColumnNumber.ToString();
            string MethodName = stackTrace.Method.Name;
            string ClassName = stackTrace.Class.Name;
            if (!string.IsNullOrEmpty(exception.Message))
            {
                Response.Redirect(String.Format("~/Error/{0}/?errorMessage={1}&fileName={2}&lineNumber={3}&columnNumber={4}&methodName={5}&className={6}", "App_Error", exception.Message, FileName, LineNumber, ColumnNumber, MethodName, ClassName));

            }
            context.Server.ClearError();
        }
