Add header into parameter (ASP.NET Web API)

Just moved my swagger dependency to NSwag. It’s great, however, there is no way to add a header (e.g X-Auth-User) as parameter for ASP.NETin Swagger UI. As FromHeader only available for ASP.NET Core, what’s the way to display header param?

I tried custom FromHeaderAttribute but it fails. public IHttpActionResult PostAuthentication([FromHeader("X-Auth-User")] string username)

in Swashbuckle, it can use IOperationFilter and

 operation.parameters.Add(new Parameter
                {
                    name = "X-Auth-User",
                    @in = "header",
                    type = "string",
                    required = true
                });

Thanks. It works.

                context.OperationDescription.Operation.Parameters.Add(new SwaggerParameter
                {
                    Name = "X-Auth-User",
                    Kind = SwaggerParameterKind.Header,
                    Type = NJsonSchema.JsonObjectType.String,
                    IsRequired = true
                     });

I will add support for FromHeaderAttribute soon…

For now you can implement a custom operation processor (see wiki, same as operation filter in Swashbuckle).
