篇(15)-Asp.Net Core入門實戰-許可權管理之用戶創建與關聯角色(ViewModel再用與模型驗證一)

在上個篇章中，講了角色和菜單的關係(也就是給角色賦權)，本章講用戶和給用戶分派角色的功能。如果是小白，最好是仔細看我寫的代碼，因為關鍵代碼處都有註解。建議將篇14和篇15閱讀完畢再做演練，為防止單篇過長，我將其分成2篇來講解。

用戶與角色的處理邏輯是：(1).用戶的增刪改查；(2).給用戶選一個所屬角色。

1.用戶管理功能

（1）.用戶表(Sql庫)的創建

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）.用戶Model的編寫，這個Model直接與Sql表的結構一致。

public class Manager
{
/// <summary>
/// 主鍵 MaxLength屬性作用於字元串，不能用在int類型上
/// </summary>
[Key]
public int Id { get; set; }
/// <summary>
/// 角色ID
/// </summary>
public int RoleId { get; set; }
/// <summary>
/// 用戶名
/// </summary>
[Required]
public String UserName { get; set; }
/// <summary>
/// 密碼
/// </summary>
public String Password { get; set; }
/// <summary>
/// 頭像
/// </summary>
public String Avatar { get; set; }
/// <summary>
/// 用戶昵稱
/// </summary>
public String NickName { get; set; }
/// <summary>
/// 手機號碼
/// </summary>
public String Mobile { get; set; }
/// <summary>
/// 郵箱地址
/// </summary>
public String Email { get; set; }
/// <summary>
/// 登錄次數
/// </summary>
public int? LoginCount { get; set; }
/// <summary>
/// 最後一次登錄IP
/// </summary>
public String LoginLastIp { get; set; }
/// <summary>
/// 最後一次登錄時間
/// </summary>
public DateTime? LoginLastTime { get; set; }
/// <summary>
/// 添加人
/// </summary>
[Required]
public int AddManagerId { get; set; }
/// <summary>
/// 添加時間
/// </summary>
[Required]
public DateTime AddTime { get; set; }
/// <summary>
/// 修改人
/// </summary>
public int? ModifyManagerId { get; set; }
/// <summary>
/// 修改時間
/// </summary>
[MaxLength(23)]
public DateTime? ModifyTime { get; set; }
/// <summary>
/// 是否鎖定
/// </summary>
[Required]
public Boolean IsLock { get; set; }
/// <summary>
/// 是否刪除
/// </summary>
[Required]
public Boolean IsDelete { get; set; }
/// <summary>
/// 備註
/// </summary>
public String Remark { get; set; }
}

（3）.用戶View部分的編寫

（3.1）視圖View部分包括用戶的增、刪、改、查功能，還有對應的修改用戶角色，修改用戶密碼。

（3.2）Create視圖代碼如下

@{ ViewData["Title"] = "新建用戶"; }
@model RegisterManagerView
@section Scripts{
<script type="text/javascript" src="~/lib/jquery-validation/dist/jquery.validate.js"></script>
<script type="text/javascript" src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>
@{ await Html.RenderPartialAsync("_ValidationScriptsPartial");}
}
<form action="/Manager/Create" method="post">
@Html.AntiForgeryToken()
<div>
<label asp-for="UserName">用戶名</label>
<div>
<input type="text" asp-for="UserName" name="UserName" placeholder="用戶名">
<span asp-validation-for="UserName" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Password">密碼</label>
<div>
<input type="password" asp-for="Password" name="Password" placeholder="密碼" />
<span asp-validation-for="Password" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="ConfirmPassword">確認密碼</label>
<div>
<input type="password" asp-for="ConfirmPassword" name="ConfirmPassword" placeholder="確認密碼" />
<span asp-validation-for="ConfirmPassword" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Mobile">手機號</label>
<div>
<input type="text" asp-for="Mobile" name="Mobile" placeholder="手機號">
<span asp-validation-for="Mobile" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Email">Email</label>
<div>
<input type="text" asp-for="Email" name="Email" placeholder="郵箱">
<span asp-validation-for="Email" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Remark">介紹</label>
<div>
<textarea name="Remark" asp-for="Remark" placeholder="相關介紹"></textarea>
</div>
</div>
<div>
<div>
<button type="submit">確定</button>
<button type="reset">重置</button>
</div>
</div>
</form>

（3.3）Edit視圖代碼如下

@{ ViewData["Title"] = "編輯用戶"; }
@model EditManagerView
@section Scripts{
<script type="text/javascript" src="~/lib/jquery-validation/dist/jquery.validate.js"></script>
<script type="text/javascript" src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>
@{ await Html.RenderPartialAsync("_ValidationScriptsPartial");}
}
<form action="/Manager/Edit" method="post">
@Html.AntiForgeryToken()
<div>
<label asp-for="UserName">用戶名</label>
<div>
<input type="text" asp-for="UserName" name="UserName" placeholder="用戶名">
<span asp-validation-for="UserName" class="text-danger"></span>
<input type="hidden" asp-for="Id" />
</div>
</div>
<div>
<label asp-for="Mobile">手機號</label>
<div>
<input type="text" asp-for="Mobile" name="Mobile" placeholder="手機號">
<span asp-validation-for="Mobile" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Email">Email</label>
<div>
<input type="text" asp-for="Email" name="Email" placeholder="郵箱">
<span asp-validation-for="Email" class="text-danger"></span>
</div>
</div>
<div>
<label asp-for="Remark">介紹</label>
<div>
<textarea name="Remark" asp-for="Remark" placeholder="相關介紹"></textarea>
</div>
</div>
<div>
<div>
<button type="submit">確定</button>
<button type="reset">重置</button>
</div>
</div>
</form>

（3.4）Index視圖代碼如下（列表頁）

@using Humanizer;
@using RjWebCms.Db;
@model PaginatedList<PageManager>
@{
ViewData["Title"] = "用戶列表";
}
@section Scripts{
<script src="~/js/jquery-3.6.1.min.js"></script>
<script type="text/javascript">
function DelAll() {
var ids = document.getElementsByName("#chk_ids");
var arrIds = "";
var n = 0;
for (var i = 0; i < ids.length; i++) {
if (ids[i].checked == true) {
arrIds += ids[i].value + ",";
n++;
}
}
if (n == 0) {
alert("請選擇要刪除的信息");
return;
}

arrIds = arrids.substr(0, arrIds.length - 1);
//
if (confirm("確定要全部刪除選擇用戶嗎")) {
$.ajax({
type: "post",
url: "/Manager/DeleteAll",
data: { ids: arrIds },
success: function (data, state) {
alert('刪除成功!');
window.location.href = "";
},

error: function (data, state) {
alert('刪除失敗');
}
});
}
}
</script>
}
<div class="panel panel-default todo-panel">
@Html.AntiForgeryToken()
<form asp-action="Index" method="get">
<table>
<tr><td><a asp-controller="Manager" asp-action="Create">添加</a></td></tr>
<tr>
<td>查詢關鍵詞:<input type="text" name="SearchString" value="@ViewData["CurrentFilter"]" /></td>
