.net core 无法将文件从脚本上载到.net Core中的Rest API

大家好，希望大家身体健康

我已经用这些技术编程很短时间了（React hooks和.net Core）

我试图以文件类型输入的形式从前端向后端的api发送一个.txt文件，但根据发送方式，我会收到多个错误。我当前试图通过FormData发送该文件，但它会抛出415媒体类型错误

415不支持的媒体类型

我想展示我认为是正确的代码来等待您的帮助< /P>的必要代码。 这是mi API端点：

public class FileUploadEndpoint : BaseAsyncEndpoint.WithRequest<FormFileDto>.WithResponse<Response<string>>
    {
        private readonly IMovimientoBusinessLogic _movimeintoBusinessLogic;
        

        public FileUploadEndpoint(IMovimientoBusinessLogic movimientoBusinessLogic)
        {
            _movimeintoBusinessLogic = movimientoBusinessLogic;
        }

       
        [HttpPost("api/fileupload")]
        [Consumes("multipart/form-data")]
        [ProducesResponseType(typeof(Response<string>), StatusCodes.Status200OK)]
        
        public async override Task<ActionResult<Response<string>>> HandleAsync(FormFileDto request, CancellationToken cancellationToken = default)
        {
            return new Response<string> { Data = request.formFile};
            
        }



    }

    
}

如果你能帮助我，谢谢你：）
