Serving a binary file as octet-stream about genhttp HOT 11 CLOSED

I am using Windows 10 Pro, Version 21H2, OS Build 19044.2006,
Experience: Windows Feature Experience Pack 120.2212.4180.0.

.NET target framework is net6.0, language version C# 10

(I hope that's what you mean by .NET version)

Actually, you should be able to just:

public class BookService
{

    [ResourceMethod]
    public Stream RequestResponse()
    {
        return File.OpenRead(@"D:\KUTE_ANIME_DESCRIPTION.OBJ");
    }

}

Thanks for the reply!

This is awesome but unfortunately I still get this exception though the file transfer works.

Just ignore it and continue? The file is around 11 mb, it doesn't happen with very small files

from genhttp.

What client do you use to access the service? Plain browser? Have to check the behaviour with large files ...

from genhttp.

Yea just plain browser, using Edge browser right now. I tried it with a Unity application also, but this time the exception was smaller.

from genhttp.

Hm, cannot reproduce the issue with this minimal example:

Host.Create()
    .Handler(ServiceResource.From<WS>())
    .Defaults()
    .Development()
    .Console()
    .Run();


class WS
{

    [ResourceMethod]
    public Stream GetResult()
    {
        return File.OpenRead(@"C:\temp\largefile.mp4");
    }

}

Can you show me how you setup your host instance and probably provide some offending test file to me?

from genhttp.

Hey!

It stopped happening with the Unity application (Happened just once), but it happens always with Edge Browser. Though I don't need it to work with Edge so for me this is fine. Also even after the exception, server runs fine.

Here's my setup code. ResourceMethod stuff is exactly the same as your example.

internal class Program
    {
        static void Main(string[] args)
        {
            ushort port = 60907;
            
            Console.WriteLine($"Starting server on http://localhost:{port}");
            var server = Host.Create();
            server.Port(port);

            var api = Layout.Create()
                .AddService<APIService>("api")
                .Add(CorsPolicy.Permissive());
                
            server.Handler(api)
                    .Defaults()
                    .Development()
                    .Console()
                    .Start(); 
            Console.ReadKey();
            Console.WriteLine("Stopped. Good bye!");
        }
    }

Edit:
File just gets stuck in upload forever but the issue happens with any 15mb+ file but only with Edge browser, doesn't happen when I do a HTTP Get request from Unity 99% of the time.

Hm, still cannot reproduce this with your bootstrapper. May I ask which operating system (and version) and .NET version you are using?

from genhttp.

Here's a list of "classic" .NET Versions in my PC.

.NET SDK 6.0.109 and 6.0.401 are installed

from genhttp.

Okay, thanks - last question: when you say "Edge", do you mean the Chromium based version of Edge?

from genhttp.

I am still not able to reproduce this behavior. In the sense of backlog grooming I am closing here - feel free to re-open as soon there is new information.
