后台SaveAttachment方法：
#region 保存上传的文件 modify by wh 2017022 //[WNet("WNet1")] public void SaveAttachment(HttpContext context) { try { #region 参数 string appId = context.Request["appId"]; string aDefId = context.Request["aDefId"]; string appType = context.Request["appType"]; int count = int.Parse(context.Request["count"]); #endregion string fileId = string.Empty; int flag = 0; //context.Request.Files.AllKeys //接收上传后的文件 for (int i = 0; i < count; i++) { HttpPostedFile file = context.Request.Files["UploadAttachment" + i + ""]; //获取文件的文件名（不包括文件的路径） if (file == null) { continue; } string fileName = file.FileName; if (!string.IsNullOrEmpty(fileName)) { string path = AppHelper.GetSysPath(SysFolder.Lgfz); if (appType == "JYZDCGTZG") { path += "/Jyzdcgt/"; } else if (appType == "JYZYCSXSB") { path += "/Jyzycsx/"; } else if (appType == "YKDCGTZG") { path += "/Ykdcgt/"; } // 判断路径是否存在，不存在则新建路径 if (!Directory.Exists(path)) { Directory.CreateDirectory(path); } FileModel fileInf = new FileModel(); string guid = Guid.NewGuid().ToString(); string filePath = path + guid + "_" + Path.GetFileName(fileName); //保存文件 file.SaveAs(filePath); fileInf.FileId = guid; fileInf.FileName = Path.GetFileName(file.FileName);//获取文件的文件名（不包括文件的路径） fileInf.FileAddress = path + guid + "_" + fileName;//文件存放地址 fileInf.ActivityId = aDefId; fileInf.AppId = appId; fileInf.CreateUser = CurrentUser.User.UserAlias; fileInf.LastModifyUser = CurrentUser.User.UserAlias; fileInf.Status = "0";//status为0——新增未保存 // 保存文件信息到数据库 Dao.SaveAttachment(fileInf); flag++; fileId += fileInf.FileId; if (i != count - 1) { fileId += ","; } } } if (flag > 0) { Dictionary<string, object> map = new Dictionary<string, object>(); map["success"] = true; map["message"] = "文件上传成功!"; map["fileId"] = fileId;// fileInf.FileId; context.Response.Write(JsonHelper.getBeanJson(map)); } else { Dictionary<string, object> map = new Dictionary<string, object>(); map["success"] = false; map["message"] = "文件为空!"; context.Response.Write(JsonHelper.getBeanJson(map)); } } catch (Exception ex) { Dictionary<string, object> map = new Dictionary<string, object>(); map["success"] = false; map["message"] = "文件上传失败!"; context.Response.Write(JsonHelper.getBeanJson(map)); Log.Error("保存文件信息异常：" + ex.Message); } } #endregion
