此请求的查询字符串的长度超过配置的maxQueryStringLength值

Question

我正在尝试重定向到视图并继续在问题标题中发布错误.

在断点测试期间,通过代码iv的第一位的代码放在设置消息和设置异常之下.在返回重定向后继续显示下一页显示如下.

向ErrorController和错误模型添加断点我发现代码永远不会到达那里.

我想要发布的视图是一个错误页面.这是代码,以帮助您看到问题.

RedirectToAction:

string message;
message = "An error has occured during the communication to lightstone, this is likely a timeout issue and could be the result of a bad connection. Please go back and try again.";
return RedirectToAction("Error", "Error", new { ex = ex.ToString(), message =  message});

我的ErrorController中的操作:

public ActionResult Error(string ex, string message)
{
   ViewBag.Message = "Error";
   return View(new ErrorModel(ex, message));
}

我的错误模型:

namespace MvcResComm.Models
{
    public class ErrorModel
    {
        public string ex { get; set; }
        public string message { get; set; }

        public ErrorModel(string ex, string message)
        {
            this.ex = ex;
            this.message = message;
        }
    }
}

Answer 1

在web.config项目的根目录下,在system.web节点下:

<system.web>
    <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" />
...

另外,我不得不在system.webServer节点下添加它,或者我的长查询字符串出现了安全性错误:

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxUrl="10999" maxQueryString="9999" />
      </requestFiltering>
    </security>
...

Answer 2

你为什么不使用TempData，它就是用来做这样的事情的。例如：

TempData["ErrorMessage"] = "An error has occured during the communication to lightstone, this is likely a timeout issue and could be the result of a bad connection. Please go back and try again.";

像这样传递您的异常消息：

TempData["Error"] = ex.Message();
TempData["ErrorMessage"] = "An error has occured during the communication to lightstone, this is likely a timeout issue and could be the result of a bad connection. Please go back and try again.";

return RedirectToAction("Error", "Error");

然后只需从您的 访问它ErrorController，例如：

public ActionResult Error(string ex, string message)
{
    var error = (string)TempData["Error"];
    // do other magic ...
}
