如何使用existingResponse =＆QUOT;自动＆QUOT;成功？

问题描述

所以，我从我的MVC的Web应用程序的详细返回400错误响应。设置existingResponse =直通的作品，但是这不是我想要的。我不希望暴露所有的失败，我只是想揭露他们时，我有自定义的响应。

汽车，是默认设置，但我特意设置。然而，文件说，SetStatus标志必须设置，但我不知道怎么做这样的事情。我写了以下四个控制器方法，以测试它，只有BadRequestD工作。其他人设置状态code和状态就好了，但身体内容是错误的请求。

 公众的ActionResult BadRequestA（）
{
    Response.Status code = 400;
    返回内容（weeeeee）;
}公众的ActionResult BadRequestB（）
{
    Response.Status =400单位DUN搞砸了;
    返回内容（weeeeee）;
}公众的ActionResult BadRequestC（）
{
    Response.Status =400单位DUN搞砸了;
    Response.Status code = 400;
    返回内容（weeeeee）;
}公众的ActionResult BadRequestD（）
{
    Response.Status code = 400;
    Response.TrySkipIisCustomErrors = TRUE;
    返回内容（weeeeee）;
}
 

解决方案

It's actually talking about the fTrySkipCustomErrors flag/argument to the IHttpResponse::SetStatus method in the IIS C++ SDK (see note I added to bottom of documentation here). But in ASP.NET the flag is exposed as Response.TrySkipIisCustomErrors. So according to:

I would expect to see IIS replace the response with its own html error page content (you can configure what that content is) by default unless you set:

Response.TrySkipIisCustomErrors = true;

Which is what you're seeing.

Additional related info, in MVC5 it seems to act as if that flag is true even if it's false for uncaught exceptions which I don't see in WebForms. As a workaround in Global.asax I'm:

protected void Application_Error()
{
    var error = Server.GetLastError();
    Server.ClearError();
    //code to log error here
    var httpException = error as HttpException;
    Response.StatusCode = httpException != null ? httpException.GetHttpCode() : (int)HttpStatusCode.InternalServerError;
}
