- DotNetNB.Security.Core：定义 core，models，Istore；实现 default memory store
- DotNetNB.Security.Store.EntityFramework：基于 mysql 创建 PermissionStore 和 ResourceStore
代码实现
我们需要在 ResourceProviderHostedService 中读取所有的 Resource，将 Resource 转换为 Permission，再将 Permission 分配给 Role
创建 Permission 的 model
namespace DotNetNB.Security.Core.Models
{
public class Permission
{
public string Key { get; set; }
public string DisplayName { get; set; }
public string Description { get; set; }
public IEnumerable Resources { get; set; }
}
}
在 IPermissionManager 接口中定义 CreateAsync 方法
namespace DotNetNB.Security.Core
{
public interface IPermissionManager
{
public Task CreateAsync(string key, string displayName, string description, IEnumerable resources);
}
}
IResourceManager 接口添加通过 key 获取 resource 的方法 GetByKeysAsync
public Task> GetByKeysAsync(IEnumerable resources);
PermissionManager 里面需要用到 Store，先定义接口 IPermissionStore
using DotNetNB.Security.Core.Models;
namespace DotNetNB.Security.Core.Store
{
public interface IPermissionStore
{
public Task CreateAsync(Permission permission);
}
}
在 PermissionManager 里面创建一个 permission，通过 ResourceManager 获取到所有 resources 赋值给 permission，再将 permission 存储到 PermissionStore
using DotNetNB.Security.Core.Models;
using DotNetNB.Security.Core.Store;
namespace DotNetNB.Security.Core;
public class PermissionManager: IPermissionManager
{
private readonly IResourceManager _resourceManager;
private readonly IPermissionStore _permissionStore;
public PermissionManager(IResourceManager resourceManager, IPermissionStore permissionStore)
{
_resourceManager = resourceManager;
_permissionStore = permissionStore;
}
public async Task CreateAsync(string key, string displayName, string description, IEnumerable resourceKeys)
{
if (string.IsNullOrEmpty(key))
throw new ArgumentNullException(nameof(key));
var permission = new Permission { Key = key, DisplayName = displayName, Description = description };
var resources = await _resourceManager.GetByKeysAsync(resourceKeys);
permission.Resources = resources;
await _permissionStore.CreateAsync(permission);
}
}
创建 DefaultPermissionStore 实现 IPermissionStore
using DotNetNB.Security.Core.Models;
namespace DotNetNB.Security.Core.Store
{
public class DefaultPermissionStore : IPermissionStore
{
private List _list;
public DefaultPermissionStore()
{
_list = new List();
}
public async Task CreateAsync(Permission permission)
{
_list.Add(permission);
}
}
}
IPermissionStore 接口添加获取 permission 列表的方法
public Task> GetAllAsync();
在 DefaultPermissionStore 中直接将列表返回即可
public async Task> GetAllAsync()
{
return _list;
}
在 PermissionManager 中通过 PermissionStore 获取 Permission 列表返回
public async Task> GetAllAsync()
{
return await _permissionStore.GetAllAsync();
}
在 IPermissionStore 中添加 GetByKeyAsync 方法，在 PermissionManager 中用于校验 key 是否存在对应的 Permission
public Task GetByKeyAsync(string key);
在 DefaultPermissionStore 中实现 GetByKeyAsync 方法
public async Task GetByKeyAsync(string key)
{
return _list.SingleOrDefault(r => r.Key == key);
}
在 PermissionManager 中校验 key 是否存在对应的 Permission
var origin = await _permissionStore.GetByKeyAsync(key);
if (origin != null)
throw new InvalidOperationException("Duplicated permission key found");
IResourceManager 接口添加获取所有 resource 方法 GetAllAsync
public Task> GetAllAsync();
ResourceManager 里面需要用到 Store，先定义接口 IResourceStore
using DotNetNB.Security.Core.Models;
namespace DotNetNB.Security.Core.Store
{
public interface IResourceStore
{
public Task CreateAsync(Resource resource);
public Task CreateAsync(IEnumerable resources);
public Task> GetAllAsync();
public Task GetByKeyAsync(string key);
public Task> GetByKeysAsync(IEnumerable resources);
}
}
创建 DefaultResourceStore 实现 IResourceStore
using DotNetNB.Security.Core.Models;
namespace DotNetNB.Security.Core.Store
{
public class DefaultResourceStore : IResourceStore
{
private readonly List _list;
public DefaultResourceStore()
{
_list = new List();
}
public async Task CreateAsync(Resource resource)
{
_list.Add(resource);
}
public async Task CreateAsync(IEnumerable resources)
{
_list.AddRange(resources);
}
public async Task> GetAllAsync()
{
return _list;
}
public async Task GetByKeyAsync(string key)
{
return _list.SingleOrDefault(r => r.Key == key);
}
public async Task> GetByKeysAsync(IEnumerable resources)
{
return _list.Where(r => resources.Contains(r.Key));
}
}
}
在 ResourceManager 中通过 ResourceStore 创建存储获取 Resource，创建的时候判断是否已经存在 Resource
using DotNetNB.Security.Core.Models;
using DotNetNB.Security.Core.Store;
namespace DotNetNB.Security.Core
{
public class ResourceManager : IResourceManager
{
private readonly IResourceStore _resourceStore;
public ResourceManager(IResourceStore resourceStore)
{
_resourceStore = resourceStore;
}
public async Task CreateAsync(Resource resource)
{
var origin = await _resourceStore.GetByKeyAsync(resource.Key);
if (origin != null)
throw new InvalidOperationException("Duplicated resource key found");
await _resourceStore.CreateAsync(resource);
}
public async Task CreateAsync(IEnumerable resources)
{
var origins = await _resourceStore.GetByKeysAsync(resources.Select(r => r.Key));
if (origins.Any())
throw new InvalidOperationException($"Duplicated resource key found:{string.Concat(origins.Select(o => o.Key), ",")}");
await _resourceStore.CreateAsync(resources);
}
public async Task> GetAllAsync()
{
return await _resourceStore.GetAllAsync();
}
public async Task> GetByKeysAsync(IEnumerable resources)
{
return await _resourceStore.GetByKeysAsync(resources);
}
}
}
