我在创建教程和同时上传文件时遇到问题。每次我尝试，邮递员都会告诉我：

“错误：错误请求”

{
  "type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
  "title": "One or more validation errors occurred.",
  "status": 400,
  "traceId": "|6030eedc-42a22f9f9c01d926.",
  "errors": {
    "$.file": [
      "The JSON value could not be converted to Microsoft.AspNetCore.Http.IFormFile. Path: $.file | LineNumber: 0 | BytePositionInLine: 141."
    ]
  }
}

我不知道如何解决这个问题...

在我的 TutorialDTO.cs 我有


public class TutorialDTO
    {
        public string Title { get; set; }
        public string PathToMdFile { get; set; }
        public string Description { get; set; }
        public string VideoLink { get; set; }
        public IList<CommentDTO> Comments { get; set; }
        public IFormFile file { get; set; }
    }

在我的 TutorialController.cs 我有


[HttpPost] 
        [DisableRequestSizeLimit]
        public async Task<Tutorial> PostTutorial(TutorialDTO tutorial)
        {

            if (tutorial.file != null)
            {
                try
                {
                    //var file = Convert.ToBase64String(Encoding.Unicode.GetBytes(tutorial.file));
                    string path_to_Files = Configuration.GetConnectionString("PathToFiles") + tutorial.file.FileName;

                    using (var stream = new FileStream(path_to_Files, FileMode.Create))
                    {

                        //file = new IFormFile("") { };
                        await tutorial.file.CopyToAsync(stream);
                    }

                    Tutorial tutorialToCreate = new Tutorial() { Title = tutorial.Title, Description = tutorial.Description, VideoLink = tutorial.VideoLink, PathToMdFile = path_to_Files };
                    _dbContext.Tutorials.Add(tutorialToCreate);
                    _dbContext.SaveChanges();

                    return tutorialToCreate;
                }
                catch (Exception e)
                {
                    Console.WriteLine(e.Message);
                }
                return null;

            }
            else
            {
                Tutorial tutorialToCreate = new Tutorial() { Title = tutorial.Title, Description = tutorial.Description, VideoLink = tutorial.VideoLink, PathToMdFile = tutorial.PathToMdFile };
                _dbContext.Tutorials.Add(tutorialToCreate);
                _dbContext.SaveChanges();

                return tutorialToCreate;
            }

        }

有人可以帮助我吗？这几天我一直在为这个问题苦苦挣扎。而且我开始厌倦这个...
