FLURL 4.0 use Newtonsoft JSON Serializer on a single request

Question

Referencing Flurl Serializers it shows that Flurl 4.0 can use the Newtonsoft based serializer, but it is not clear to me how to do this for a single request. I need this to address a circular loop error in my request.

Answer 1

Here is sample code to do that

// this is needed when serializing classes to prevent circular loop error
var settings = new JsonSerializerSettings
{
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};
// create a Newtonsoft-based serializer for Flurl to use
var serializer = new Flurl.Http.Newtonsoft.NewtonsoftJsonSerializer(settings);

var result = await urlOrRequest
    // apply the serializer just to this request
    .WithSettings(settings => settings.JsonSerializer = serializer)
    .PostJsonAsync(data);
