asp.net zero 8.2 学习-6-权限控制

asp.net zero给服务配置权限的步骤：

• 定义权限标识符 SIS.Core层 Authorization/AppPermissions.cs
• 创建权限 SIS.Core层 Authorization/AppAuthorizationProvider.cs
• 菜单权限配置 SIS.Web.Mvc层 Areas/app/Startup/appNavigationProviders.cs
• 对应服务及方法权限配置 AbpAuthorize()
• 权限测试及API访问 https://localhost:44302/api/TokenAuth/Authenticate

定义权限标识符

在SIS.Core项目的Authorization/AppPermissions.cs文件中，添加相应的权限

// demo
public const string Pages_Demo = "Pages.Demo";
public const string Pages_Demo_Create = "Pages.Demo.Create";
public const string Pages_Demo_Edit = "Pages.Demo.Edit";
public const string Pages_Demo_Delete = "Pages.Demo.Delete";

创建权限

在SIS.Core层的Authorization/AppAuthorizationProvider.cs中创建权限：
创建权限过程中，使用了字符串需要多语言配置，在SIS.Core项目下Localization>SIS目录下SIS-zh-Hans.xml配置对应字符串的中文

var demo = pages.CreateChildPermission(AppPermissions.Pages_Demo, L("Demo"));
demo.CreateChildPermission(AppPermissions.Pages_Demo_Create, L("CreatingNewDemo"));
demo.CreateChildPermission(AppPermissions.Pages_Demo_Edit, L("EditingDemo"));
demo.CreateChildPermission(AppPermissions.Pages_Demo_Delete, L("DeletingDemo"));

多语言配置：

    <text name="Demo">测试页面</text>
    <text name="DemoHeaderInfo">测试页面副标题</text>
    <text name="CreatingNewDemo">创建测试实体</text>
    <text name="EditingDemo">编辑测试实体</text>
    <text name="DeletingDemo">删除测试实体</text>

分配权限

给菜单分配页面权限：

 .AddItem(new MenuItemDefinition(
                        appPageNames.Common.Demo,
                        L("Demo"),
                        url: "app/Demo",
                        icon: "flaticon-line-graph",
                        permissionDependency: new SimplePermissionDependency(AppPermissions.Pages_Demo)
                    )

给服务类及方法配置权限

using Abp.Collections.Extensions;
using Abp.Domain.Repositories;
using EDU.SIS.Demo.Dtos;
using System.Linq;
using System.Threading.Tasks;

using Abp.Authorization;
using EDU.SIS.Authorization;

    {
        private readonly IRepository<DemoObject> _demoObjectRepository;
        public DemoObjectAppService(IRepository<DemoObject> demoObjectRepository)
        {
            _demoObjectRepository = demoObjectRepository;
        }

        public async Task CreateOrEdit(CreateOrEditDemoObjectDto input)
        {
            if (input.Id==null)
            {
                //创建
               await Create(input);
            }
            else
            {
                //修改

            }
        }

        {
            //注意这里要用Abp.Linq.Extensions，否则返回的是IEnumerable类型
            var filter = _demoObjectRepository.GetAll()
                .WhereIf(!string.IsNullOrWhiteSpace(input.Filter), e => e.Name.Contains(input.Filter))
                .WhereIf(!string.IsNullOrWhiteSpace(input.NameFilter), e => e.Name.Equals(input.NameFilter));

            //先排序，再映射
            filter = filter.OrderBy(input.Sorting ?? "id asc");//OrderBy来自System.Linq.Dynamic.Core

            var query = (from o in filter
                         orderby o.Id
                         select new GetDemoObjectForViewDto()
                         {
                             DemoObject = ObjectMapper.Map<DemoObjectDto>(o)
                         });

            var result = new PagedResultDto<GetDemoObjectForViewDto>()
            {
                TotalCount = totalCount,
                Items = demoObject

        }
    }
}

权限测试及API访问

###页面权限
运行应用程序，在管理->角色点击修改，能够看到我们定义的权限：

API请求token

由于我们加了权限，需要通过请求token，才能有权限访问服务，请求accesstoken地址：https://localhost:44302/api/TokenAuth/Authenticate 具体配置如下图：
header要加上租户ID，应为系统默认开启了多租户，可以在SIS.Core项目SISCoreModule.cs中查看到Configuration.MultiTenancy.IsEnabled = SISConsts.MultiTenancyEnabled;

body加上用户名和密码：

带token分页查询

查询需要复制上一步请求的accesstoken,在分页查询请求中的Header添加Authorization,具体如下图，添加accesstoken就可以请求成功：

同样带token添加实体也是与分页查询一样：
