.net core3.1 abp動態菜單和動態權限（動態菜單實現和動態權限添加）（三）

abp, netcore

我們來創建動態菜單吧

首先，先對動態菜單的概念、操作、流程進行約束：
1.Host和各個Tenant有自己的自定義菜單
2.Host和各個Tenant的權限與自定義菜單相關聯
2.Tenant有一套默認的菜單，規定對應的TenantId=-1，在添加租戶時自動將標準菜單和標準菜單的權限初始化到添加的租戶

一、先實現菜單在數據庫中的增刪改查

第一步：創建表、實體，添加DbContext

我們需要創建一個菜單表，延續Abp的命名方法，表名叫AbpMenus吧（菜單和權限、驗證我們要關聯，所以文件盡量放在Authorization文件夾下）

把創建的實體放在AbpLearn.Core/Authorization下面，新建一個Menus文件夾，再創建Menus實體

    public class AbpMenus : Entity<int>
    {
        public string MenuName { set; get; }
        public string PageName { set; get; }
        public string Name { set; get; }
        public string Url { set; get; }
        public string Icon { set; get; }
        public int ParentId { set; get; }
        public bool IsActive { set; get; }
        public int Orders { set; get; }
        public int? TenantId { set; get; }
    }

如果翻過源碼中實體的定義，可以發現很多實體的繼承，例如：

1.繼承接口 IMayHaveTenant，繼承後生成的sql語句將自動增加TenantId的查詢條件，表中必須包含TenantId列
2.繼承接口 IPassivable，繼承後表中必須包含IsActive列
3.繼承接口 FullAuditedEntity<TPrimaryKey> TPrimaryKey可以是long、int等值類型，必須包含IsDeleted、DeleterUserId、DeletionTime，其中這個接口
        還繼承了AuditedEntity<TPrimaryKey>, IFullAudited, IAudited, ICreationAudited, IHasCreationTime, IModificationAudited, IHasModificationTime, IDeletionAudited, IHasDeletionTime, ISoftDelete，這些父類型、接口的定義自己F12就可以看到

AbpLearn.EntityFrameworkCore/EntityFrameworkCore/AbpLearnDbContext.cs增加DbSet

public class AbpLearnDbContext : AbpZeroDbContext<Tenant, Role, User, AbpLearnDbContext>
    {
        /* Define a DbSet for each entity of the application */
        
        public AbpLearnDbContext(DbContextOptions<AbpLearnDbContext> options)
            : base(options)
        {
            
        }

        public DbSet<AbpMenus> AbpMenus { set; get; }

    }

再去數據庫中添加AbpMenus表字段長度請自行調整

DROP TABLE IF EXISTS `AbpMenus`;
CREATE TABLE `AbpMenus` (
`Id` int NOT NULL AUTO_INCREMENT,
`MenuName` varchar(50) DEFAULT NULL,
`PageName` varchar(50) DEFAULT NULL,
`LName` varchar(50) DEFAULT NULL,
`Url` varchar(50) DEFAULT NULL,
`Icon` varchar(20) DEFAULT NULL,
`ParentId` int DEFAULT NULL,
`IsActive` bit(1) NOT NULL DEFAULT b’0′,
`Orders` int DEFAULT NULL,
`TenantId` int DEFAULT NULL,
PRIMARY KEY (`Id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

第二步：添加Service和Dto

AbpLearn.Application/Authorization下添加Menus文件夾，然後添加IMenusAppService、MenusAppService，然後添加Dto文件夾

第三步：添加控制器和前台頁面、js

Controller文件，MenusController.cs

前台添加Menus及對應的js文件，可以簡單省事的把其他文件夾複製粘貼一份，然後關鍵詞修改下

這些文件太多了，我會把這套代碼上傳到github中，文章最低部會把鏈接掛出來

添加完之後我們就可以生成預覽一下Menus，因為SetNavigation中未將Menus的url加進去，我們自己手打鏈接進入

此時，我們的菜單這一塊的crud已經做好了，我們可以看到有一個Host管理員這個部分是什麼意思哪？

我們為了在當前Host中可以控制所有租戶的菜單和權限，將當前Host、標準菜單、租戶做一個select，代碼如下

    public class ChangeModalViewModel
    {
        public int? TenantId { get; set; }

        public string TenancyName { get; set; }

        public int? TenantMenuType { get; set; }


        public List<ComboboxItemDto> TeneacyItems { get; set; }
    }

        public async Task<IActionResult> IndexAsync(int? id = 0)
        {
            var loginTenant = id <= 0 ? null : _tenantManager.GetById((int)id);

            var viewModel = new ChangeModalViewModel
            {
                TenancyName = loginTenant?.TenancyName,
                TenantId = id
            };

            viewModel.TeneacyItems = _tenantManager.Tenants
                .Select(p => new ComboboxItemDto(p.Id.ToString(), p.Name) { IsSelected = viewModel.TenancyName == p.TenancyName })
                .ToList();

            viewModel.TeneacyItems.Add(new ComboboxItemDto("0","Host管理員") { IsSelected = id == 0 });

            viewModel.TeneacyItems.Add(new ComboboxItemDto("-1", "默認菜單") { IsSelected = id == -1 });

            ViewBag.LoginInfo = await _sessionAppService.GetCurrentLoginInformations();

            return View(viewModel);
        }

然後在Index.cshtml中添加或修改

@model ChangeModalViewModel  // 添加

@await Html.PartialAsync(“~/Views/Menus/Index.AdvancedSearch.cshtml”, Model) //修改

@await Html.PartialAsync(“~/Views/Menus/_CreateModal.cshtml”,Model.TenantId) //修改

//添加

$(“#ChangeTenancyName”).change(function (e) {
location.href = “/Menus/Index/” + this.options[this.selectedIndex].value;
});

                       Model.TeneacyItems.Select(i => i.ToSelectListItem()),
                       new { @class = "form-control edited", id = "ChangeTenancyName" })
                </div>
            </div>
    </div>

因為在abp裏面加載當前列表調用的是abp.services.app.menus.getAll方法，我們還需要對MenusAppService中的GetAllAsync做一下修改

    [Serializable]
    public class MenusPagedResultRequestDto: PagedResultRequestDto, IPagedAndSortedResultRequest
    {
        public virtual int? TenantId { get; set; }

        public virtual string Sorting { get; set; }

        public virtual bool ShowAll { get; set; }

    }

        #region 查詢全部菜單
        /// <summary>
        /// 查詢全部菜單
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public override async Task<PagedResultDto<MenuDto>> GetAllAsync(MenusPagedResultRequestDto input)
        {
            IQueryable<AbpMenus> query;

            query = CreateFilteredQuery(input).Where(o => o.TenantId == (input.TenantId == 0 ? null : input.TenantId));

            var totalCount = await AsyncQueryableExecuter.CountAsync(query);

            query = ApplySorting(query, input);
            if (!input.ShowAll) query = ApplyPaging(query, input);

            var entities = await AsyncQueryableExecuter.ToListAsync(query);

            return new PagedResultDto<MenuDto>(
                totalCount,
                entities.Select(MapToEntityDto).ToList()
            );
        }

        #endregion

這樣，我們在選中下面中的任意一個Tenant時，將會跳到對應的菜單裏面了

我們先把Host管理員菜單和默認菜單配置一下

二、實現添加租戶時，初始化標準菜單和權限

首先我們找到添加租戶的地方，去TenantAppService裏面去找，可以看到有CreateAsync的重寫

        public override async Task<TenantDto> CreateAsync(CreateTenantDto input)
        {
            CheckCreatePermission();

            // Create tenant
            var tenant = ObjectMapper.Map<Tenant>(input);
            tenant.ConnectionString = input.ConnectionString.IsNullOrEmpty()
                ? null
                : SimpleStringCipher.Instance.Encrypt(input.ConnectionString);

            var defaultEdition = await _editionManager.FindByNameAsync(EditionManager.DefaultEditionName);
            if (defaultEdition != null)
            {
                tenant.EditionId = defaultEdition.Id;
            }

            await _tenantManager.CreateAsync(tenant);
            await CurrentUnitOfWork.SaveChangesAsync(); // To get new tenant's id.

            // Create tenant database
            _abpZeroDbMigrator.CreateOrMigrateForTenant(tenant);

            // We are working entities of new tenant, so changing tenant filter
            using (CurrentUnitOfWork.SetTenantId(tenant.Id))
            {
                // Create static roles for new tenant
                CheckErrors(await _roleManager.CreateStaticRoles(tenant.Id));

                await CurrentUnitOfWork.SaveChangesAsync(); // To get static role ids

                // Grant all permissions to admin role
                var adminRole = _roleManager.Roles.Single(r => r.Name == StaticRoleNames.Tenants.Admin);
                await _roleManager.GrantAllPermissionsAsync(adminRole);

                // Create admin user for the tenant
                var adminUser = User.CreateTenantAdminUser(tenant.Id, input.AdminEmailAddress);
                await _userManager.InitializeOptionsAsync(tenant.Id);
                CheckErrors(await _userManager.CreateAsync(adminUser, User.DefaultPassword));
                await CurrentUnitOfWork.SaveChangesAsync(); // To get admin user's id

                // Assign admin user to role!
                CheckErrors(await _userManager.AddToRoleAsync(adminUser, adminRole.Name));
                await CurrentUnitOfWork.SaveChangesAsync();
            }

            return MapToEntityDto(tenant);
        }

我們需要做的是，在 using (CurrentUnitOfWork.SetTenantId(tenant.Id)) 的內部尾部添加賦予菜單和權限的方法即可

賦予菜單和權限的方法我們分開寫，都放在MenusAppService中，

    public interface IMenusAppService : IAsyncCrudAppService<MenuDto, int, MenusPagedResultRequestDto, CreateMenuDto, MenuDto>
    {
        /// <summary>
        /// 賦予默認菜單
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        Task GiveMenusAsync(EntityDto<int> input);

        /// <summary>
        /// 賦予當前租戶Admin角色菜單權限
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        Task GivePermissionsAsync(EntityDto<int> input);
    }

        #region 賦予默認菜單
        public async Task GiveMenusAsync(EntityDto<int> input)
        {
            if (input.Id > 0)
            {
                var tenant = await _tenantManager.GetByIdAsync(input.Id);

                using (_unitOfWorkManager.Current.SetTenantId(tenant.Id))
                {
                    var query = CreateFilteredQuery(new MenusPagedResultRequestDto()).Where(o => o.TenantId == tenant.Id);

                    var systemMenus = await AsyncQueryableExecuter.ToListAsync(query);

                    if (!systemMenus.Any())
                    {
                        query = CreateFilteredQuery(new MenusPagedResultRequestDto()).Where(o => o.TenantId == -1);

                        var defaultMenus = await AsyncQueryableExecuter.ToListAsync(query);
                        if (defaultMenus.Any())
                        {
                            foreach (var entity in defaultMenus)
                            {
                                await CreateAsync(new AbpMenus()
                                {
                                    LName = entity.LName,
                                    MenuName = entity.MenuName,
                                    PageName = entity.PageName,
                                    Icon = entity.Icon,

現在我們添加租戶企業1、企業2

現在菜單已經同步好了，我們去數據庫看下權限的同步

TenantId：

null是Host

1是abp頁面第一次加載時初始化的Default租戶

2是我之前添加的舊的企業1，那個時候方法沒寫好，就把2的刪掉了

3是企業2

4是企業1

由此可以看出，我們添加的菜單對應的PageName已經作為權限添加到權限表了

三、實現菜單修改後，權限賦予對應租戶

這一個其實在二裏面已經寫好了，前台做一個按鈕，賦予權限，調用一下就好了

例如：

Index.cshtml //為什麼要加getCurrentLoginInformationsOutput.Tenant == null的判斷？是因為租戶在進入菜單管理的地方，我們不給他們添加、賦予權限的權限

在/wwwroot/view-resources/Views/Menus/Index.js中添加

    $(document).on('click', '#GivePermissions', function (e) {
        var tenantId = $(this).attr('data-tenant-id');

        abp.message.confirm(
            abp.utils.formatString(
                "是否賦予當前租戶管理員賬號所有權限？",
                "系統"
            ),
            null,
            (isConfirmed) => {
                if (isConfirmed) {
                    _menuService
                        .givePermissions({
                            id: tenantId
                        })
                        .done(() => {
                            abp.notify.info("操作成功！");
                            _$menusTable.ajax.reload();
                        });
                }
            }
        );
    });

四、實現菜單的動態加載

在//www.cnblogs.com/wangpengzong/p/13089690.html中我們找到了菜單生成的地方，在最底部，通過NavigationManager來獲取到Menus，這裡其實有一個初始化方法（Initialize），調用的是AbpLearnNavigationProvider的SetNavigation方法來進行本地化，然後在

NavigationManager的非靜態構造函數中去獲取已經本地化的Menus，但是本地化Menus因為是在初始化時，程序的初始化我們無法獲取到當前的Tenant信息，所以只能將獲取Menus的地方推遲，放在倒數第二個類UserNavigationManager裏面的GetMenuAsync方法中，我們來看下GetMenuAsync

        public async Task<UserMenu> GetMenuAsync(string menuName, UserIdentifier user)
        {
            var menuDefinition = _navigationManager.Menus.GetOrDefault(menuName);
            if (menuDefinition == null)
            {
                throw new AbpException("There is no menu with given name: " + menuName);
            }

            var userMenu = new UserMenu(menuDefinition, _localizationContext);
            await FillUserMenuItems(user, menuDefinition.Items, userMenu.Items);
            return userMenu;
        }

第一句話獲取menuDefinition是關鍵點，我們將menuDefinition修改為從數據庫中獲取，在AbpLearn.Application/Authorization/Menus下添加UserNavigationManager.cs

                    if (menuItemDefinition.PermissionDependency != null &&
                        (user == null || !(await menuItemDefinition.PermissionDependency.IsSatisfiedAsync(permissionDependencyContext))))
                    {
                        continue;
                    }

                    if (menuItemDefinition.FeatureDependency != null &&
                        (AbpSession.MultiTenancySide == MultiTenancySides.Tenant || (user != null && user.TenantId != null)) &&
                        !(await menuItemDefinition.FeatureDependency.IsSatisfiedAsync(featureDependencyContext)))
                    {
                        continue;
                    }

                    var userMenuItem = new UserMenuItem(menuItemDefinition, _localizationContext);
                    if (menuItemDefinition.IsLeaf || (await FillUserMenuItems(user, menuItemDefinition.Items, userMenuItem.Items)) > 0)
                    {
                        userMenuItems.Add(userMenuItem);
                        ++addedMenuItemCount;
                    }
                }
            }

            return addedMenuItemCount;
        }
    }
}

然後在Mvc項目的Startup.cs/ConfigureServices下增加

            services.AddScoped<IUserNavigationManager, UserNavigationManager>();

因為在abp中菜單被做做成了模塊，在程序初始化時模塊添加進去，但是我們將菜單修改成了每次讀取數據庫加載，那麼我們就不需要加載這個模塊了

在mvc項目的AbpLearnWebMvcModule.cs注釋下面這句話

            //Configuration.Navigation.Providers.Add<AbpLearnNavigationProvider>();

將AbpLearnNavigationProvider.cs/SetNavigation方法的內容全部注釋掉

預覽一下mvc，用Host登錄一下

用企業1登陸下，登錄切換Host和Tenant，是在登錄界面 Current tenant: 未選 (Change) 點擊Change，在彈框中輸入 E1（因為上面設置的企業1標識是E1），點擊save，頁面刷新後就變為了 Current tenant: E1 (Change) ，輸入賬號密碼登錄

OK，我們的動態菜單已經完成了

當然，我的菜單使用的是table來顯示，你也可以使用tree來，我找到了一個jstree，下面修改一下

MenusAppService.cs

        #region 獲取當前賬戶的菜單樹
        /// <summary>
        /// 獲取當前賬戶的菜單樹
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public async Task<string> GetTreeAsync(MenusPagedResultRequestDto input)
        {
            var query = CreateFilteredQuery(new MenusPagedResultRequestDto()).Where(o => o.TenantId == input.TenantId);

            var systemMenus = await AsyncQueryableExecuter.ToListAsync(query);

            var childJObject = new JObject();
            var openJObject = new JObject();
            openJObject.Add("opened", true);
            childJObject.Add("id", 0);
            childJObject.Add("text", "根目錄");
            childJObject.Add("icon", "");
            childJObject.Add("state", openJObject);
            childJObject.Add("children", GetJArray(systemMenus, 0));
            return childJObject.ToString();
        }

        #region 獲取目錄Array
        /// <summary>
        /// 獲取目錄Array
        /// </summary>
        /// <param name="systemMenus"></param>
        /// <param name="parentdId"></param>
        /// <returns></returns>
        private JArray GetJArray(List<AbpMenus> systemMenus, int parentdId)
        {
            JArray jArray = new JArray();
            foreach (var menu in systemMenus.Where(o => o.ParentId == parentdId))
            {
                var jObject = new JObject();
                jObject.Add("id", menu.Id);
                jObject.Add("text", menu.MenuName);
                jObject.Add("icon", menu.Icon);
                //jObject.Add("state", menu.Icon);
                if (systemMenus.Any(o => o.ParentId == menu.Id))
                {
                    jObject.Add("children", GetJArray(systemMenus, menu.Id));
                }
                jArray.Add(jObject);
            }
            return jArray;
        }

        #endregion

        #endregion

前端Index.cshtml jstree去//github.com/vakata/jstree/zipball/3.3.8下載，下載後在mvc項目的wwwroot文件夾下添加jstree文件夾，下載文件的src裏面內容全部賦值到jstree文件夾

注釋掉table標籤

添加jstree1

例如：

@section styles
{
    <link href="~/jstree/themes/default/style.css" rel="stylesheet" />
}                     

       <div id="jstree1" style="width:100%;"></div>



@section scripts
{
    <environment names="Development">

    </environment>

    <environment names="Staging,Production">
