.Net5.0 上传图片、文件到服务器

今天来看看.net上传图片到服务器的方式

　　public class ControlPresetUploadInput
    {
        /// <summary>
        /// 通道编号
        /// </summary>
        public string ChannelId { set; get; }

        /// <summary>
        /// 预置位编号
        /// </summary>
        public int PresetId { set; get; }

        /// <summary>
        /// 传入的文件
        /// </summary>
        public IFormFile InputImageFile { set; get; }
    }

　　　　　[HttpPost]
        [Route("uploadImage")]
        [Authorize(IntelligentRemotePatrolPermissions.PresetInformations.Default)]
        public async Task<IResponseOutput> UploadImage([FromForm] ControlPresetUploadInput input)
        {
            string url = string.Empty;
            if (input.InputImageFile == null)
                return ResponseOutput.Ok(new PresetUploadMinioDto());
            try
            {
                string name = $"{input.ChannelId + "-" + input.PresetId}.jpg";
                url = await SubmitImagesToMinioAsync(input.InputImageFile, name);
                //存库记录
                await _fileUploadInformation.InsertAsync(new FileUploadInformation
                {
                    Length = input.InputImageFile.Length,
                    Url = url,
                    Type = input.InputImageFile.ContentType,
                    Size = null,
                    Name = name,
                    Model = "Preset",
                });
            }
            catch (Exception ex)
            {
                throw new UserFriendlyException(ex.Message);
            }
            return ResponseOutput.Ok(url);
        }

上传文件到服务器 （都差不多）

 public class ExcelImportInput
    {

        /// <summary>
        /// 传入的文件
        /// </summary>
        public IFormFile file { set; get; }

    }

    public class ExcelImportExtensionInput : ExcelImportInput
    {
        /// <summary>
        /// 各类ID，可以是单位ID，也可以是上级ID等等
        /// </summary>
        public string id { get; set; }

    }

　　　　  [HttpPost]
        [Route("importUnitsByXml")]
        public async Task<IActionResult> ImportUnitsByXml([FromForm] ExcelImportInput input)
        {
            if (input.file == null || input.file.Length <= 0)
                return Json(new { Success = false, Message = "请上传文件" });

            if (!input.file.FileName.ToLower().Contains(".xml"))
                return Json(new { Success = false, Message = "请上传xml文件" });

            string sWebRootFolder = _hostingEnvironment.ContentRootPath;
            string sFileName = $"units_{DateTime.Now:yyMMddHHmmssfff}.xml";
            var fullPath = Path.Combine(sWebRootFolder, "wwwroot", "ImportXml", sFileName);
            FileHelper.CreateDirectoryIfFilePathNotExists(fullPath);
            try
            {
                FileInfo file = new FileInfo(fullPath);
                using (FileStream fs = new FileStream(file.ToString(), FileMode.Create))
                {
                    input.file.CopyTo(fs);
                    fs.Flush();
                }
                XmlDocument doc = new XmlDocument();
                doc.Load(fullPath);

                var list = await _ledgerMessageAppService.GetXmlModelAttributes(new PatrolEquipmentDto(), doc.InnerXml);

                //剔除type不是单位的实体 <20>: = 区域巡视主机 <21>: =  边缘节点
                list.RemoveAll(s => !",20,21,".Contains(s.type));
                await _ledgerMessageAppService.XmlToAreaPatrolHost(list);
                return Json(new { Success = true, Message = "导入成功" });
            }
            catch (Exception ex)
            {
                return Json(new { Success = false, Message = ex.Message });
            }
        }
