如何为Swashbuckle BodyParam v4.0.1设置默认值？

Question

所以我基本上有这样的签名：

[HttpGet, Route("widget/{widgetId}"), ResponseType(typeof(Widget))]
public async Task<IActionResult> GetWidgetWithValues([FromQuery] DashboardFilters filters, int widgetId = 1024)

像这样的DashboardFilters POCO：

public class DashboardFilters
{
    [DefaultValue("6/1/2019")]
    public DateTime Start { get; set; }
    public DateTime End { get; set; }
    public IEnumerable<int> UniversityIds { get; set; }
    [SwaggerDefaultValue("Test", "Hello there")]
    public string Test { get; set; }
}

我尝试设置'DefaultValue'和'SwaggerDefaultValueAttribute'

 [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)]
    internal class SwaggerDefaultValueAttribute : Attribute
    {
        public SwaggerDefaultValueAttribute(string parameterName, object value) => (this.ParameterName, this.Value) = (parameterName, value);

        public string ParameterName { get; private set; }
        public object Value { get; set; }
    }

基本上没有任何作用。我仍然可以使用此命令轻松设置标头参数：

public class SwaggerAddAuthHeader : IOperationFilter
{
    public void Apply(Operation operation, OperationFilterContext context)
    {
        if (operation.Parameters == null)
            operation.Parameters = new List<IParameter>();

        operation.Parameters.Add(new NonBodyParameter
        {
            Name = "Authorization",
            Description = "JWT",
            In = "header",
            Type = "string",
            Default = "Bearer "
        });

    }
}

将其连接起来，像这样：

 services.AddSwaggerGen(x =>
        {
            x.SwaggerDoc("v1", new Info { Title = $"Admin API", Version = "v1", Description = $"Last updated: {settings.General.DateUpdated}" });

            //This enables the /// comments on each method to be used better for swagger
            x.IncludeXmlComments(Assembly.GetExecutingAssembly().Location.Replace(".dll", ".xml"));
            x.OperationFilter<SwaggerAddAuthHeader>();
        });

我试图在SwaggerAddAuthHeader中为'BodyParameter'添加一些内容，并且'default'属性消失了。有人碰到这个吗？似乎很奇怪，您没有办法为复杂类型定义默认值。是的，我知道使用简单的原语就可以像上面一样生成它们的默认值。
