篇(15)-Asp.Net Core入门实战-权限管理之用户创建与关联角色(ViewModel再用与模型验证一)

篇(15)-Asp.Net Core入门实战-权限管理之用户创建与关联角色(ViewModel再用与模型验证一)

在上个篇章中,讲了角色和菜单的关系(也就是给角色赋权),本章讲用户和给用户分派角色的功能。如果是小白,最好是仔细看我写的代码,因为关键代码处都有注解。建议将篇14和篇15阅读完毕再做演练,为防止单篇过长,我将其分成2篇来讲解。

用户与角色的处理逻辑是:(1).用户的增删改查;(2).给用户选一个所属角色。

1.用户管理功能

(1).用户表(Sql库)的创建

篇(15)-入门实战-权限管理之用户创建与关联角色(ViewModel再用与模型验证一)

CREATE TABLE [dbo].[Manager]( [Id] [int] IDENTITY(1,1) NOT NULL, [RoleId] [int] NOT NULL, [UserName] [varchar](32) NOT NULL, [Password] [varchar](128) NOT NULL, [Avatar] [varchar](256) NULL, [NickName] [varchar](32) NULL, [Mobile] [varchar](16) NULL, [Email] [varchar](128) NULL, [LoginCount] [int] NULL, [LoginLastIp] [varchar](64) NULL, [LoginLastTime] [datetime] NULL, [AddManagerId] [int] NOT NULL, [AddTime] [datetime] NOT NULL, [ModifyManagerId] [int] NULL, [ModifyTime] [datetime] NULL, [IsLock] [bit] NOT NULL, [IsDelete] [bit] NOT NULL, [Remark] [varchar](128) NULL, CONSTRAINT [PK_MANAGER] PRIMARY KEY NONCLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO

 

(2).用户Model的编写,这个Model直接与Sql表的结构一致。

public class Manager { /// <summary> /// 主键 MaxLength属性作用于字符串,不能用在int类型上 /// </summary> [Key] public int Id { get; set; } /// <summary> /// 角色ID /// </summary> public int RoleId { get; set; } /// <summary> /// 用户名 /// </summary> [Required] public String UserName { get; set; } /// <summary> /// 密码 /// </summary> public String Password { get; set; } /// <summary> /// 头像 /// </summary> public String Avatar { get; set; } /// <summary> /// 用户昵称 /// </summary> public String NickName { get; set; } /// <summary> /// 手机号码 /// </summary> public String Mobile { get; set; } /// <summary> /// 邮箱地址 /// </summary> public String Email { get; set; } /// <summary> /// 登录次数 /// </summary> public int? LoginCount { get; set; } /// <summary> /// 最后一次登录IP /// </summary> public String LoginLastIp { get; set; } /// <summary> /// 最后一次登录时间 /// </summary> public DateTime? LoginLastTime { get; set; } /// <summary> /// 添加人 /// </summary> [Required] public int AddManagerId { get; set; } /// <summary> /// 添加时间 /// </summary> [Required] public DateTime AddTime { get; set; } /// <summary> /// 修改人 /// </summary> public int? ModifyManagerId { get; set; } /// <summary> /// 修改时间 /// </summary> [MaxLength(23)] public DateTime? ModifyTime { get; set; } /// <summary> /// 是否锁定 /// </summary> [Required] public Boolean IsLock { get; set; } /// <summary> /// 是否删除 /// </summary> [Required] public Boolean IsDelete { get; set; } /// <summary> /// 备注 /// </summary> public String Remark { get; set; } }

 

(3).用户View部分的编写

(3.1)视图View部分包括用户的增、删、改、查功能,还有对应的修改用户角色,修改用户密码。

(4).用户Controller部分的实现

public class ManagerController : Controller{   private readonly IManagerService _manager;   private readonly IManagerRoleService _managerRoleService;   private readonly AppDbContext _appDbContext;   public ManagerController(IManagerService manager,IManagerRoleService managerRoleService, AppDbContext appDbContext){     _manager = manager;     _managerRoleService = managerRoleService;     _appDbContext = appDbContext;   }   public async Task<IActionResult> Index(string sortOrder, string currentFilter, string searchString, int? pageNumber){     ViewData["CurrentSort"] = sortOrder;     ViewData["NameSortParm"] = String.IsNullOrEmpty(sortOrder) ?

} }  return View(); }  public async Task<IActionResult> Details(int id) { var item = await _manager.FindManagerAsync(id); return View(item); }  public async Task<IActionResult> Delete(int id) { var result = await _manager.DeleteManagerAsync(id);

2.用户分配角色

分配角色在ChangeRole视图页面完成,注意阅读其对应代码;
