Upload von sehr großen Dateien in Asp.Net MVC Core 2 einstellen.

 

Problem:

Wenn man in asp.net core 2.1 mvc große Dateien oder Videos mit 200 MB oder 1,5 GB hochladen möchte, dann stellt man schnell fest,

dass der Upload des Formulars oder der ajax webapi mit dem Fehler 404.13 oder 502.3 beantwortetet wird.

Das liegt daran, dass man bei Asp.net Core die erlaubte Upload-Begrenzung vom Standard einstellen muss.

 

Lösung:

Ich habe jetzt gut 2 Tage um eine Lösung in Foren und bei Microsoft gesucht und endlich in einem kleinen Beitrag die Lösung gefunden

Man muss in der startup.cs die services.configure einstellen

//--< set uploadsize large files >----

services.Configure<FormOptions>(options =>

{

    options.ValueLengthLimit = int.MaxValue;

    options.MultipartBodyLengthLimit = int.MaxValue;

    options.MultipartHeadersLengthLimit = int.MaxValue;

});

//--</ set uploadsize large files >----

In der Web.config habe wie üblich die requestFiltering ergänzt.

Wenn diese fehlen, dann entsteht der Fehler 404

      <requestFiltering>

        <requestLimits maxAllowedContentLength="1073741824" />

Program.cs

In der program.cs kann man die Timeouts einstellen.

.UseKestrel(options =>

{

    options.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(120);

    options.Limits.RequestHeadersTimeout = TimeSpan.FromMinutes(120);

Asp.Net Core MVC Controller

In der eigentlichen Controller Methode kann man dann die Upload-Grenzen nochmals speziefisch für diese Methode einstellen.

Hierzu kann man das Attribut RequestSizeLimit vor die Methode stellen

//[DisableRequestSizeLimit]

[RequestSizeLimit(500000000)]  //30.000.000=28,6MB
