ASP.NET CORE WebApi接口示例

示例提供来源：A0~海阔天空

创建ASP.NET CORE API项目数据库访问自行百度,数据库结构参考文档就行，结构都类似。

数据对象如下：

  1.    /// <summary>
  2.     /// 菜单表
  3.     /// </summary>
  4.     [Table("bee_system_menu")]
  5.     public class SystemMenuEntity
  6.     {
  7.         /// <summary>
  8.         /// ID
  9.         /// </summary>
  10.         [Key]
  11.         [Required]
  12.         public long id { get; set; }
  14.         /// <summary>
  15.         /// 父级ID
  16.         /// </summary>
  17.         [Required]
  18.         public long pid { get; set; }
  19.         /// <summary>

  42.         public int sort { get; set; }
  44.         /// <summary>
  45.         /// 是否菜单
  46.         /// </summary>
  47.         public bool status { get; set; }
  48.     }
  1.    /// <summary>
  2.     /// 菜单结果对象
  3.     /// </summary>
  4.     public class MenusInfoResultDTO
  5.     {
  6.         /// <summary>
  7.         /// 权限菜单树
  8.         /// </summary>
  9.         public List<SystemMenu> MenuInfo { get; set; }
  11.         /// <summary>
  12.         /// logo

  14.         public LogoInfo LogoInfo { get; set; }
  16.         /// <summary>
  17.         /// Home
  18.         /// </summary>
  19.         public HomeInfo HomeInfo { get; set; }
  20.     }
  22.     public class LogoInfo
  23.     {
  24.         public string title { get; set; } = "sdsdsdsff";
  25.         public string image { get; set; } = "images/logo.png";
  26.         public string href { get; set; } = "";
  27.     }
  29.     public class HomeInfo
  30.     {
  31.         public string title { get; set; } = "首页";
  32.         public string href { get; set; } = "page/welcome-1.html?t=1";
  34.     }
  36.     /// <summary>
  37.     /// 树结构对象
  38.     /// </summary>
  39.     public class SystemMenu
  40.     {
  41.         /// <summary>
  42.         /// 数据ID
  43.         /// </summary>
  44.         public long Id { get; set; }
  46.          /// <summary>
  47.         /// 父级ID
  48.         /// </summary>
  49.         public long PId { get; set; }
  51.         /// <summary>
  52.         /// 节点名称
  53.         /// </summary>
  54.         public string Title { get; set; }
  56.         /// <summary>
  57.         /// 节点地址
  58.         /// </summary>
  59.         public string Href { get; set; }
  61.         /// <summary>
  62.         /// 新开Tab方式
  63.         /// </summary>
  64.         public string Target { get; set; } = "_self";
  66.         /// <summary>
  67.         /// 菜单图标样式
  68.         /// </summary>
  69.         public string Icon { get; set; }
  71.         /// <summary>
  72.         /// 排序
  73.         /// </summary>
  74.         public int Sort { get; set; }
  76.         /// <summary>
  77.         /// 子集
  78.         /// </summary>
  79.         public List<SystemMenu> Child { get; set; }
  80.     }

创建一个根对象来接受处理好的数据

  1.     SystemMenu rootNode = new SystemMenu()
  2.     {
  3.         Id = 0,
  4.         Icon = "",
  5.         Href = "",
  6.         Title = "根目录",
  7.     };

递归处理数据库返回的数据方法参考如下，

  1.     /// <summary>
  2.     /// 递归处理数据
  3.     /// </summary>
  4.     /// <param name="systemMenuEntities"></param>
  5.     /// <param name="rootNode"></param>
  6.     public static void GetTreeNodeListByNoLockedDTOArray(SystemMenuEntity[] systemMenuEntities, SystemMenu rootNode)
  7.     {
  8.         if (systemMenuEntities == null || systemMenuEntities.Count() <= 0)
  9.         {
  10.             return;
  11.         }
  13.         var childreDataList = systemMenuEntities.Where(p => p.pid == rootNode.Id);
  14.         if (childreDataList != null && childreDataList.Count() > 0)
  15.         {
  16.             rootNode.Child = new List<SystemMenu>();
  18.             foreach (var item in childreDataList)
  19.             {
  20.                 SystemMenu treeNode = new SystemMenu()
  21.                 {
  22.                     Id = item.id,
  23.                     Icon = item.icon,
  24.                     Href = item.href,
  25.                     Title = item.title,
  26.                 };
  27.                 rootNode.Child.Add(treeNode);
  28.             }
  30.             foreach (var item in rootNode.Child)
  31.             {
  32.                 GetTreeNodeListByNoLockedDTOArray(systemMenuEntities, item);
  33.             }
  34.         }
  35.     }

最后将rootNode的Child 赋值返回给 MenusInfoResultDTO.MenuInfo 返回给前端就行
