开发任务

• DotNetNB.Security.Core：定义 core，models，Istore；实现 default memory store
• DotNetNB.WebApplication：创建 ResourceController 和 PermissionController 进行验证

代码实现

• ResourceController
• PermissionController

ResourceController

创建 ResourceController，通过 ResourceManager 获取所有 Resource

using DotNetNB.Security.Core;
using Microsoft.AspNetCore.Mvc;

namespace DotNetNB.WebApplication.Controllers

    [ApiController]
    [Route("[controller]")]
    public class ResourceController : ControllerBase
    
        private readonly IResourceManager _resourceManager;

        public ResourceController(IResourceManager resourceManager)
        
            _resourceManager = resourceManager;
        


        [HttpGet]
        [Route("")]
        public async Task<IActionResult> GetAll()
        
            return Ok(await _resourceManager.GetAllAsync());
        
    

在 Program 中先将 AddEntityAccessControl 进行注释

builder.Services.AddSecurity(options =>

    options.AddActionAccessControl();
    //.AddEntityAccessControl();
);

在 ServiceCollectionExtensions 的扩展方法 AddSecurity 中创建 option，并调用，同时注入 Store 和 Manager

using DotNetNB.Security.Core.Store;
using Microsoft.Extensions.DependencyInjection;

namespace DotNetNB.Security.Core.Extensions

    public static class ServiceCollectionExtensions
    
        public static IServiceCollection AddSecurity(this IServiceCollection services, Action<SecurityOption>? configure)
        
            var option = new SecurityOption  Services = services ;
            configure?.Invoke(option);
        
            services.AddSingleton<IResourceStore, DefaultResourceStore>()
                .AddSingleton<IPermissionStore, DefaultPermissionStore>()
                .AddScoped<IResourceManager, ResourceManager>()
                .AddScoped<IPermissionManager, PermissionManager>()
                .AddHostedService<ResourceProviderHostedService>();
            return services;
        
    

在 ResourceProviderHostedService 的 StartAsync 方法中将 host 启动时的所有 action 注入进来

using DotNetNB.Security.Core.Models;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace DotNetNB.Security.Core

    public class ResourceProviderHostedService : IHostedService
    
        private readonly IServiceProvider _serviceProvider;

        public ResourceProviderHostedService(IServiceProvider serviceProvider)
        
            _serviceProvider = serviceProvider;
        

        public async Task StartAsync(CancellationToken cancellationToken)
        
            using var scope = _serviceProvider.CreateScope();
            var providers = scope.ServiceProvider.GetServices<IResourceProvider>();
            var resourceManager = scope.ServiceProvider.GetService<IResourceManager>();

            var resources = new List<Resource>();
            foreach (var provider in providers)
            
                resources.AddRange(await provider.ExecuteAsync());
            

            await resourceManager.CreateAsync(resources);
        

        public async Task StopAsync(CancellationToken cancellationToken)
        
        
    

设置 DotNetNB.WebApplication 为启动项，启动项目，可以通过接口看到 action 相关信息

PermissionController

创建 PermissionController，通过 PermissionManager 获取所有 Permission

using DotNetNB.Security.Core;
using Microsoft.AspNetCore.Mvc;

namespace DotNetNB.WebApplication.Controllers

    [ApiController]
    [Route("[controller]")]
    public class PermissionController : ControllerBase
    
        private readonly IPermissionManager _permissionManager;

        public PermissionController(IPermissionManager permissionManager)
        
            _permissionManager = permissionManager;
        

        [HttpGet]
        public async Task<IActionResult> GetAll()
        
            return Ok(await _permissionManager.GetAllAsync());
        
    

创建 dto 对象 CreatePermissionRequest

namespace DotNetNB.WebApplication.ViewModels

    public class CreatePermissionRequest
    
        public string Key  get; set; 

        public string DisplayName  get; set; 

        public string Description  get; set; 

        public IEnumerable<string> resources  get; set; 
    

在 PermissionController 中添加创建 Permission 的接口

[HttpPost]
public async Task<IActionResult> Create([FromBody] CreatePermissionRequest request)

    await _permissionManager.CreateAsync(request.Key, request.DisplayName, request.Description, request.resources);
    return Ok();

在 Program 中将我们的 Permission 模块添加到 Identity 模块上，相当于一个桥接

builder.Services.AddIdentity<IdentityUser<string>, IdentityRole<string>>()
    .WithPermissions<IdentityUser<string>, IdentityRole<string>>();
