How can I hook into RegisterResponseContentEncodingForContentType

[brendonparker]

How can I hook into AbstractAspNetCoreFunction.RegisterResponseContentEncodingForContentType to add additional content types that I need Base64 encoded using the Amazon.Lambda.AspNetCoreServer.Hosting package?

For better or worse, I want to add font/woff2 to the list, for example.

I've found a work around, but seems a bit hacky. Ideally there is a more elegant way...

I basically had to copy small parts of the source and modify them, creating my own custom APIGatewayHttpApiV2LambdaRuntimeSupportServer and then a custom extension method to register it similar to AddAWSLambdaHosting

All that to add the one line for RegisterResponseContentEncodingForContentType

Custom LambdaRuntimeSupportServer

public class CustomAPIGatewayHttpApiV2LambdaRuntimeSupportServer : LambdaRuntimeSupportServer
{
    public CustomAPIGatewayHttpApiV2LambdaRuntimeSupportServer(IServiceProvider serviceProvider)
        : base(serviceProvider)
    {
    }

    protected override HandlerWrapper CreateHandlerWrapper(IServiceProvider serviceProvider)
    {
        var handler = new APIGatewayHttpApiV2MinimalApi(serviceProvider).FunctionHandlerAsync;
        return HandlerWrapper.GetHandlerWrapper(handler, new DefaultLambdaJsonSerializer());
    }

    public class APIGatewayHttpApiV2MinimalApi : APIGatewayHttpApiV2ProxyFunction
    {
        public APIGatewayHttpApiV2MinimalApi(IServiceProvider serviceProvider)
            : base(serviceProvider)
        {
            // THIS IS THE LINE I WANT/NEED TO ADD 
            RegisterResponseContentEncodingForContentType("font/woff2", ResponseContentEncoding.Base64);
        }
    }
}

Custom ExtensionMethod

public static class ServiceCollectionExtensions
{
    public static IServiceCollection AddAWSLambdaHostingCustomized(this IServiceCollection services)
    {
        // Not running in Lambda so exit and let Kestrel be the web server
        if (string.IsNullOrEmpty(Environment.GetEnvironmentVariable("AWS_LAMBDA_FUNCTION_NAME")))
            return services;

        Utilities.EnsureLambdaServerRegistered(services, typeof(CustomAPIGatewayHttpApiV2LambdaRuntimeSupportServer));
        return services;
    }
}

@normj Do you mind checking me on this. Think this is PR worthy for some better way of extending this?
