本文的项目是官网生成，项目名称为XX，WEB为MVC，以Users权限模块为例解说文章。
1.定义PermissionNames
PermissionNames是一个静态类，它在/XX.Core/Authorization之下
public const string Pages_Users = "Pages.Users";
// 子权限名称// public const string Pages_Users_Create = "Pages.Users.Create";
2.添加权限控制
XXAuthorizationProvider.cs，修改SetPermissions方法
public override void SetPermissions(IPermissionDefinitionContext context)
{
//Common permissions
var pages = context.GetPermissionOrNull(PermissionNames.Pages);
if (pages == null)
{
pages = context.CreatePermission(PermissionNames.Pages, L("Pages"));
}
var users = pages.CreateChildPermission(PermissionNames.Pages_Users, L("Users"));//这里是自定义的权限
//users.CreateChildPermission(PermissionNames.Pages_Users_Create, L("Users_Create"));//这里是自定义的子权限
}
3.添加菜单权限
在web项目下的App_Start中有一个XXNavigationProvider类，它在XXWebModule类的PreInitialize配置
在XXNavigationProvider类的SetNavigation方法中进行添加菜单，且控制配置权限
context.Manager.MainMenu
.AddItem(
new MenuItemDefinition(
"Home",
L("HomePage"),
url: "",
icon: "fa fa-home",
requiresAuthentication: true
)
).AddItem(
new MenuItemDefinition(
"Tenants",
L("Tenants"),
url: "Tenants",
icon: "fa fa-globe",
requiredPermissionName: PermissionNames.Pages_Tenants
)
).AddItem(
new MenuItemDefinition(
"Users",
L("Users"),
url: "Users",
icon: "fa fa-users",
requiredPermissionName: PermissionNames.Pages_Users //这是自定义的权限
)
).AddItem(
new MenuItemDefinition(
"About",
L("About"),
url: "About",
icon: "fa fa-info"
)
);
}
4.展示菜单
在Layout控制器中，使用局部视图TopMenu进行展示，到这里已经完成
@using Abp.Collections.Extensions
@using Zmcor.Web.Views
@model Zmcor.Web.Models.Layout.TopMenuViewModel
@{
var calculateMenuUrl = new Func<string, string>((url) =>
{
if (string.IsNullOrEmpty(url))
{
return ApplicationPath;
}
if (UrlChecker.IsRooted(url))
{
return url;
}
return ApplicationPath + url;
});
}
@foreach (var menuItem in Model.MainMenu.Items)
{
<li class="@(Model.ActiveMenuItemName == menuItem.Name ? "active" : "")">
@if (menuItem.Items.IsNullOrEmpty())
{
<a href="@calculateMenuUrl(menuItem.Url)">
@if (!string.IsNullOrWhiteSpace(menuItem.Icon))
{
<i class="@menuItem.Icon"></i>
}
@menuItem.DisplayName
</a>
}
else
{
<a href="" data-toggle="dropdown">
@if (!string.IsNullOrWhiteSpace(menuItem.Icon))
{
<i class="@menuItem.Icon"></i>
}
@menuItem.DisplayName
</a>
<ul class="dropdown-menu">
@foreach (var subMenuItem in menuItem.Items)
{
<li>
<a href="@calculateMenuUrl(subMenuItem.Url)">
@if (!string.IsNullOrWhiteSpace(subMenuItem.Icon))
{
<i class="@subMenuItem.Icon"></i>
}
@subMenuItem.DisplayName
</a>
</li>
}
</ul>
}
</li>
}
5.角色和权限的关联
为用户添加角色
在UserAppService注入UserManager
private readonly UserManager _userManager;
设置角色代码
/// <summary>
/// 设置用户角色
/// </summary>
/// <returns></returns>
public async Task SetUserRole(long currentUserId, long userId, string[] roleName)
{
//权限判断...
var user = _userRepository.FirstOrDefault(s => s.Id == userId);
await _userManager.SetRoles(user, roleName);
}
在abp中，默认有Admin角色，如果需要创建自己的角色，如下
var myRole = new Role(null,"roleName", "我的角色名称"); await _roleManager.CreateAsync(myRole);
为角色分配权限
控制器
//视图显示 [HttpGet]
public async Task<ActionResult> SetRoleMenu(int Id)
{
var role = _roleAppService.GetRolesById(Id);
var myPermissions = await _roleAppService.GetGrantedPermissionsAsync(Id);//数据库中角色对应的权限
ViewBag.MyPermissions = myPermissions;
var rolePermissions = _roleAppService.GetRolePermissionsForManage();
var dictList = new Dictionary<string, string>();
foreach (var item in rolePermissions)
{
dictList.Add(item.Name, item.DisplayName.ToString().Split(' ')[1].Trim(','));
}
ViewBag.RoleList = dictList;//步骤2所定义的权限
return View(role);
}
//提交[HttpPost]
public async Task<JsonNetResult> SetRoleMenu(int Id, string PermissionNames)
{
try
{
PermissionNames = Request.Form["PermissionNames"];
if (string.IsNullOrWhiteSpace(PermissionNames))
{
return new JsonNetErrorResult("请至少选择一个角色！");
}
var roleNames = PermissionNames.Split(',').ToList();
var input = new UpdateRolePermissionsInput() { RoleId = Id, GrantedPermissionNames = roleNames };
var userInfo = GetCurrentUserInfo();
await _roleAppService.UpdateRolePermissions(userInfo.UserId,input);
return new JsonNetSuccessResult();
}
catch (Exception ex)
{
return new JsonNetErrorResult("更新出错" + ex.Message);
}
}
应用层
public async Task<List<string>> GetGrantedPermissionsAsync(int roleId)
{
List<string> grantedList = new List<string>();
var grantedPermissions = await _roleManager.GetGrantedPermissionsAsync(roleId);
foreach (var item in grantedPermissions)
{
grantedList.Add(item.Name);
}
return grantedList;
}
public List<Permission> GetRolePermissionsForManage()
{
var grantedPermissions = _permissionManager
.GetAllPermissions()
.Where(s => s.Name.Contains("Pages."))
.ToList();
return grantedPermissions;
}
public async Task UpdateRolePermissions(long userId, UpdateRolePermissionsInput input)
{
var userAndRole = _userRepository.GetUserAndRolesById(userId);
if (userAndRole == null || userAndRole.IsAdmin()))
{
throw new UserFriendlyException("您无权限进行该操作");
}
var role = await _roleManager.GetRoleByIdAsync(input.RoleId);
// 如果有子权限，只要添加父权限，会自动添加子权限
//var grantedPermission = _permissionManager
// .GetAllPermissions()
// .Where(p => input.GrantedPermissionNames.Any(s=> p.Name.Contains(s)))
// .ToList();
var grantedPermissions = _permissionManager
.GetAllPermissions()
.Where(p => input.GrantedPermissionNames.Contains(p.Name))
.ToList();
await _roleManager.SetGrantedPermissionsAsync(role, grantedPermissions);
}
IPermissionManager使用_permissionManager.GetAllPermissions() 可以获取到在步骤2所添加的权限
获取当前角色的权限：RoleManager => GetGrantedPermissionsAsync(roleId)
获取所有权限：IPermissionManager=> GetAllPermissions()
更新权限：RoleAppService=> UpdateRolePermissions(UpdateRolePermissionsInput input)
input.GrantedPermissionNames为需授权的权限列表
扩展：授权验证
控制器授权
[AbpMvcAuthorize(PermissionNames.Pages_Users)] public class UsersController : XXControllerBase
Action授权
[AbpMvcAuthorize(PermissionNames.Companys)]
[HttpGet]
public async Task<ActionResult> Main()
{
return View();
}
应用层的授权
[AbpAuthorize(PermissionNames.Pages_Users)]
public class UserAppService : ZmcorAppServiceBase, IUserAppService
总结：角色权限这个模块，整体使用的还是比较简单、畅通的，注意还需要配置相关的本地化语言文件。如果存在比较复杂的角色和权限，还需要经过一定的设计才能获得良好的体验
