            [FromForm] int? mediaId = null)
        {
            content = content.Replace(@"\n", "\n");
            Post post = new Post()

这不是最好的解决方案，但它可能对某人有用：

[HttpPost("{heading}/{content}/{tagId:int}/{mediaId:int}")]
        public async Task<IActionResult> CreatePost([FromForm]string? heading, 
            [FromForm]string content, 
            [FromForm] int tagId, 
            [FromForm] int? mediaId = null)
        {
            content = content.Replace(@"\n", "\n");
            Post post = new Post()
            {
                heading = heading,
                content = content,
                tag = tagId,
                mediaId = mediaId,
                date = DateTime.UtcNow,
            };
            _unitOfWork.PostRepository.Create(post);
            _unitOfWork.Save();
            return Ok(post);
        }

        [HttpPost]
        public async Task<IActionResult> CreatePost([FromForm] string? heading,
            [FromForm] string content,
            [FromForm] int tagId,
            [FromForm] IFormFile? file = null)
        {
            content = content.Replace(@"\n", "\n");
            var mediaResult = await _fileManager.UploadFile(file);
            Post post = new Post()
            {
                heading = heading,
                content = content,
                tag = tagId,
                mediaId = mediaResult.id,
                date = DateTime.UtcNow,
            };
            _unitOfWork.PostRepository.Create(post);
            _unitOfWork.Save();
            return Ok(post);
        }
