SetHttpResponseStatusCode without using reflection

[YaroslavKormushyn]

Thanks for the example project!

To anyone wondering, if there's a better way of setting the response code on the HTTP response if a 401 or 403 happens:

Microsoft published a sample middleware doing just that https://github.com/Azure/azure-functions-dotnet-worker/blob/a5fc0632d233b242debfd1485e527315567b9b3a/samples/CustomMiddleware/ExceptionHandlingMiddleware.cs#L47-L58
You just need to update to the latest function worker package.
My version is:

• Microsoft.Azure.Functions.Worker 1.20.0

So instead of doing reflection in the SetHttpResponseStatusCode method, you could do this:

public static async Task SetHttpResponseStatusCode(
    this FunctionContext context,
    HttpStatusCode statusCode)
{
    var httpResponse = (await context.GetHttpRequestDataAsync()).CreateResponse(statusCode);
    var httpOutputBindingFromMultipleOutputBindings = context.GetOutputBindings<HttpResponseData>()
        .FirstOrDefault(b => b.BindingType == "http" && b.Name != "$return");

    if (httpOutputBindingFromMultipleOutputBindings is not null)
    {
        httpOutputBindingFromMultipleOutputBindings.Value = httpResponse;
    }
    else
    {
        var invocationResult = context.GetInvocationResult();
        invocationResult.Value = httpResponse;
    }
}
