swagger 4.0 asp.net core 2.2需要body参数

我使用的是带有asp.net core 2.2web api的swagger 4.0。我想告诉post/put方法上的swagger ui,需要一些body内容参数。如我所知,如果参数是查询参数,那么它是必需的。做了一些研究 https://swagger.io/docs/specification/2-0/describing-request-body/ 并发现可以将正文内容

其他环节的一些研究

How to mark a property as required in Swagger, without ASP.NET model validation?

How can I tell Swashbuckle that the body content is required?

控制器代码

[HttpPost]
        public async Task<IActionResult> Create([FromBody]LearningApplication model)
        {
            if (!ModelState.IsValid) return InvalidModelState(ModelState);

            // create the record,no need to provide resource auth as only admin can action this controller
            await _learningApplicationManager.CreateAsync(model, LearningApplicationValidator.OnCreateRuleset);

            return Created(url, model);
        }

模型

public class LearningApplication : BaseAuditableWithLogicalDeleteAggregate<Guid>
    {

        [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter the name of the course or professional Learning session")]
        [DataMember]
        public string CourseName { get; set; }

        [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter the professional Learning provider: ie. TGS, AGSV, etc")]
        [DataMember]
        public string Provider { get; set; }

        [DataMember]
        public string EventWebsite { get; set; }

        [DataMember]
        public string RegistrationExpenses { get; set; }

        [Required(ErrorMessage = "Please provide the Start Date & time")]
        [DataMember]
        public DateTime? StartDateTime { get; set; }
}
