Right way to get to ILambdaContext for AWS Serverless Application

[genifycom]

I am looking in public abstract class APIGatewayHttpApiV2ProxyFunction to find a way to access ILambdaContext lambdaContext to extract the lambdaContext.AwsRequestId

.Should we be overriding MarshallRequest?

If you need the request id inside the subclass of APIGatewayHttpApiV2ProxyFunction then you would need to override the PostMarshallItemsFeatureFeature method.

If you are looking to get ahold of the ILambdaContext inside the ASP.NET Core side of your function this code snippet shows you how to do it.

using Amazon.Lambda.Core;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers();
builder.Services.AddAWSLambdaHosting(LambdaEventSource.RestApi);

var app = builder.Build();

app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();

app.MapGet("/", (HttpContext context) =>
{
    var lambdaContext = context.Items[Amazon.Lambda.AspNetCoreServer.AbstractAspNetCoreFunction.LAMBDA_CONTEXT] as ILambdaContext;
    if(lambdaContext == null)
    {
        return "no request id";
    }

    return lambdaContext.AwsRequestId;
});

app.Run();
