问题 I have written a custom http handler. I have done this by writing a class which implements the IHttphandler. Inside that class I have code like this, context.Response.Clear(); context.Response.ClearHeaders(); context.Response.AddHeader("Content-Disposition", "attachment;filename=" + attachmentFileName); context.Response.AddHeader("Content-Length", new FileInfo(downloadFile).Length.ToString()); context.Response.ContentType = GetMimeType(attachmentFileName); context.Response.TransmitFile

ASP.NET Core equivalent of ASP.NET MVC 5's HttpException

问题 In ASP.NET MVC 5 you could throw a HttpException with a HTTP code and this would set the response like so: throw new HttpException((int)HttpStatusCode.BadRequest, "Bad Request."); HttpException does not exist in ASP.NET Core. What is the equivalent code? 回答1: I implemented my own HttpException and supporting middleware which catches all HttpException 's and turns them into the corresponding error response. A short extract can be seen below. You can also use the Boxed.AspNetCore Nuget package.

Since Response.Redirect(string url) uses the Http "Location" response header ( http://en.wikipedia.org/wiki/HTTP_headers#Responses ), calling it will cause the headers to be sent to the client. This means that if you call it a second time, or if you call it

Catching “Maximum request length exceeded”

由 萝らか妹 提交于 2019-11-26 10:14:40
I'm writing an upload function, and have problems catching "System.Web.HttpException: Maximum request length exceeded" with files larger than the specified max size in httpRuntime in web.config (max size set to 5120). I'm using a simple <input> for the file. The problem is that the exception is thrown before the upload button's click-event, and the exception happens before my code is run. So how do I catch and handle the exception? EDIT: The exception is thrown instantly, so I'm pretty sure it's not a timeout issue due to slow connections. Damien McGivern There is no easy way to catch such
