add custom claims with object value

[althunibat]

i couldn't find a way to add custom claims to JwsDescriptor which accepts claim value as object, where it get automatically json serialized when jwt is written.

e.g.

descriptor.AddClaim("https://hasura.io/jwt/claims", new HasuraClaim
{
UserId = user.Id,
DefaultRole = "user",
Roles = new[] { "user" }
});

Hi, there is not way to serialize a custom object for the moment. You can this achieve by using a JwtObject and a JwtArray:

            var descriptor = new JwsDescriptor();
            descriptor.AddClaim("https//hasura.io/jwt/claims", new JwtObject
            {
                { "user_id", 123 },
                { "default_role", "user" },
                { "roles", new JwtArray { "user"} }
            });

This is "by design" for avoiding two issues:
1/ Casing issue : how should be cased the custom property names? With the JwtObject, you specify the casing.
2/ Type mismatch : custom objects contains custom value types and there is always debates on its representation in JSON. The JwtObject only support native JSON types (String, Number, Boolean & Null) and the DateTime because there is convention for the mapping (epoch time).

For convenience it should be interessant to allow

                { "roles", new[] { "user"} }

for hiding the JwtArray in case of string array.

Fixed in version 2.0.0-beta.1

Jwt/samples/JwsCreationSample/Program.cs

Lines 62 to 84 in 1c98645

	descriptor.Payload.Add("ClaimName_anonymous_type", new
	{
	stuff1 = "xyz789",
	stuff2 = "abc123",
	subObject = new
	{
	prop1 = "abc123",
	prop2 = "xyz789"
	},
	Modules = new[]
	{
	new {
	name = "module1",
	prop1 = "abc123",
	prop2 = "xyz789"
	},
	new {
	name = "module2",
	prop1 = "abc123",
	prop2 = "xyz789"
	}
	}
	});

If required, the JSON serialization behavior can be controled with the JsonSerializationBehavior.SerializerOptions property, for example by adding a JsonConverter<HasuraClaim> to JsonSerializationBehavior.SerializerOptions.Converters
