怎样优雅地增删查改（二）：扩展身份管理模块
@
身份管理模块（Identity模块）为通用查询接口的按组织架构查询和按户关系查询提供查询依据。
身份管理模块的领域层依赖Volo.Abp.Identity.Domain
Abp为我们实现了一套身份管理模块，此模块包含用户管理、角色管理、组织管理、权限管理等功能。详细请参考身份管理模块。
我们将基于Volo.Abp.Identity模块按需求扩展。将为其扩展组织管理功能的接口，以及人员关系（Relation）功能。
用户关系管理
Relation是人员之间的关系，比如：签约、关注，或者朋友关系等。人员之间的关系是单项的，也就是说可以A是B的好友，但B不一定是A的好友。
关系类型由Type来定义
正向关系：User -> RelatedUser，由查询GetRelatedToUsersAsync实现；
反向关系：RelatedUser -> User，由查询GetRelatedFromUsersAsync实现。
添加Relation实体：
public class Relation : FullAuditedAggregateRoot<long>
{
public Guid? TenantId { get; set; }
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public override long Id { get; protected set; }
public Guid UserId { get; set; }
[ForeignKey("UserId")]
public IdentityUser User { get; set; }
public Guid RelatedUserId { get; set; }
[ForeignKey("RelatedUserId")]
public IdentityUser RelatedUser { get; set; }
public string Type { get; set; }
}
在模块配置中添加
public class IdentityEntityFrameworkCoreModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddAbpDbContext<IdentityDbContext>(options =>
{
options.AddRepository<IdentityUserOrganizationUnit, EfCoreRepository<IdentityDbContext, IdentityUserOrganizationUnit>>();
options.AddRepository<Relation.Relation, EfCoreRepository<IdentityDbContext, Relation.Relation>>();
});
}
}
创建RelationManager，实现人员关系的正向和反向查询
public async Task<List<Relation>> GetRelatedToUsersAsync(Guid userId, string type)
{
var query = (await Repository.GetQueryableAsync())
.WhereIf(userId != null, c => userId == c.UserId)
.WhereIf(!string.IsNullOrEmpty(type), c => c.Type == type);
var items = query.ToList();
return items;
}
public async Task<List<Relation>> GetRelatedFromUsersAsync(Guid userId, string type)
{
var query = (await Repository.GetQueryableAsync())
.Where(c => userId == c.RelatedUserId)
.WhereIf(!string.IsNullOrEmpty(type), c => c.Type == type);
var items = query.ToList();
return items;
}
扩展组织管理功能
组织（OrganizationUnit）是身份管理模块的核心概念，组织是树形结构，组织之间存在父子关系。
我们对功能模块的接口进行扩展：
-
增加OrganizationUnit的增删查改接口；
-
增加OrganizationUnit的移动接口；
-
增加人员与组织架构管理接口，如添加/删除人员到组织架构，查询组织架构下的人员，查询未分配组织的人员等；
-
增加查询根组织（GetRootOrganizationUnit）接口。
完整的应用层接口如下：
public interface IOrganizationUnitAppService : IBasicCurdAppService<OrganizationUnitDto, Guid, CreateOrganizationUnitInput, UpdateOrganizationUnitInput>, IApplicationService
{
Task AddToOrganizationUnitAsync(UserToOrganizationUnitInput input);
Task<List<OrganizationUnitDto>> GetCurrentOrganizationUnitsAsync();
Task<PagedResultDto<IdentityUserDto>> GetOrganizationUnitUsersByPageAsync(GetOrganizationUnitUsersInput input);
Task<List<IdentityUserDto>> GetOrganizationUnitUsersAsync(GetOrganizationUnitUsersInput input);
Task<OrganizationUnitDto> GetRootOrganizationUnitAsync(Guid id);
Task<List<OrganizationUnitDto>> GetRootOrganizationUnitsAsync(IEnumerable<Guid> ids);
Task<OrganizationUnitDto> GetRootOrganizationUnitByDisplayNameAsync(GetRootOrganizationUnitByDisplayName input);
Task<List<OrganizationUnitDto>> GetRootOrganizationUnitsByParentAsync(GetRootOrganizationUnitsByParentInput input);
Task<bool> IsInOrganizationUnitAsync(UserToOrganizationUnitInput input);
Task MoveOrganizationUnitAsync(MoveOrganizationUnitInput input);
Task RemoveUserFromOrganizationUnitAsync(UserToOrganizationUnitInput input);
Task<List<IdentityUserDto>> GetUsersWithoutOrganizationAsync(GetUserWithoutOrganizationInput input);
Task<PagedResultDto<IdentityUserDto>> GetUsersWithoutOrganizationByPageAsync(GetUserWithoutOrganizationInput input);
}
创建可查询仓储
通用查询接口过滤条件需要对IQueryable进行拼接，由于Volo.Abp.Identity.IIdentityUserRepository继承自IBasicRepository，我们需要重新编写一个IdentityUser的可查询仓储：QueryableIdentityUserRepository
其实现接口IQueryableIdentityUserRepository的定义如下：
public interface IQueryableIdentityUserRepository : IIdentityUserRepository
{
Task<IQueryable<OrganizationUnit>> GetOrganizationUnitsQueryableAsync(Guid id, bool includeDetails = false);
Task<IQueryable<IdentityUser>> GetOrganizationUnitUsersAsync(
Guid id, string keyword, string[] type,
bool includeDetails = false);
Task<IQueryable<IdentityUser>> GetUsersWithoutOrganizationAsync(string keyword, string[] type);
}
实现控制器
为OrganizationUnitAppService 以及 RelationAppService 创建MVC控制器
完整的 OrganizationUnitController 代码如下：
namespace Matoapp.Identity.OrganizationUnit
{
[Area(IdentityRemoteServiceConsts.ModuleName)]
[RemoteService(Name = IdentityRemoteServiceConsts.RemoteServiceName)]
[Route("api/identity/organizationUnit")]
public class OrganizationUnitController : IdentityController, IOrganizationUnitAppService
{
private readonly IOrganizationUnitAppService _organizationUnitAppService;
public OrganizationUnitController(IOrganizationUnitAppService organizationUnitAppService)
{
_organizationUnitAppService = organizationUnitAppService;
}
[HttpPost]
[Route("AddToOrganizationUnit")]
public async Task AddToOrganizationUnitAsync(UserToOrganizationUnitInput input)
{
await _organizationUnitAppService.AddToOrganizationUnitAsync(input);
}
[HttpPost]
[Route("Create")]
public async Task<OrganizationUnitDto> CreateAsync(CreateOrganizationUnitInput input)
{
return await _organizationUnitAppService.CreateAsync(input);
}
[HttpDelete]
[Route("Delete")]
public async Task DeleteAsync(Guid id)
{
await _organizationUnitAppService.DeleteAsync(id);
}
[HttpGet]

{
return await _organizationUnitAppService.GetUsersWithoutOrganizationByPageAsync(input);
}
[HttpGet]
[Route("IsInOrganizationUnit")]
public async Task<bool> IsInOrganizationUnitAsync(UserToOrganizationUnitInput input)
{
return await _organizationUnitAppService.IsInOrganizationUnitAsync(input);
}
[HttpPost]
[Route("MoveOrganizationUnit")]
public async Task MoveOrganizationUnitAsync(MoveOrganizationUnitInput input)
{
await _organizationUnitAppService.MoveOrganizationUnitAsync(input);
}
[HttpPost]
[Route("RemoveUserFromOrganizationUnit")]
public async Task RemoveUserFromOrganizationUnitAsync(UserToOrganizationUnitInput input)
{
await _organizationUnitAppService.RemoveUserFromOrganizationUnitAsync(input);
}
[HttpPut]
[Route("Update")]
public async Task<OrganizationUnitDto> UpdateAsync(UpdateOrganizationUnitInput input)
{
return await _organizationUnitAppService.UpdateAsync(input);
}
}
完整的 RelationController 代码如下：
[Area(IdentityRemoteServiceConsts.ModuleName)]
[RemoteService(Name = IdentityRemoteServiceConsts.RemoteServiceName)]
[Route("api/identity/relation")]
public class RelationController : IdentityController, IRelationAppService
{
private readonly IRelationAppService _relationAppService;
public RelationController(IRelationAppService relationAppService)
{
_relationAppService = relationAppService;
}
[HttpDelete]
[Route("ClearAllRelatedFromUsers")]
public async Task ClearAllRelatedFromUsersAsync(GetRelatedUsersInput input)
{
await _relationAppService.ClearAllRelatedFromUsersAsync(input);
}
[HttpDelete]
[Route("ClearAllRelatedToUsers")]
public async Task ClearAllRelatedToUsersAsync(GetRelatedUsersInput input)
{
await _relationAppService.ClearAllRelatedToUsersAsync(input);
}
[HttpPost]
[Route("Create")]
public async Task<RelationDto> CreateAsync(ModifyRelationInput input)
{
return await _relationAppService.CreateAsync(input);
}
[HttpDelete]
[Route("Delete")]
public async Task DeleteAsync(EntityDto<long> input)
{
await _relationAppService.DeleteAsync(input);
}
[HttpDelete]
[Route("DeleteByUserId")]
public async Task DeleteByUserIdAsync(ModifyRelationInput input)
{
await _relationAppService.DeleteByUserIdAsync(input);
}

return await _relationAppService.GetRelatedToUserIdsAsync(input);
}
[HttpGet]
[Route("GetRelatedFromUserIds")]
public async Task<List<Guid>> GetRelatedFromUserIdsAsync(GetRelatedUsersInput input)
{
return await _relationAppService.GetRelatedFromUserIdsAsync(input);
}
}
测试接口
上一章节我们已经将三个模组的依赖添加到MatoappHttpApiModule中，直接启动HttpApi.Host就可以访问接口了。
[DependsOn(
...
typeof(CommonHttpApiModule),
typeof(HealthHttpApiModule),
typeof(IdentityHttpApiModule)
)]
public class MatoappHttpApiModule : AbpModule
Relation相关接口：
OrganizationUnit相关接口：
下一章节将介绍如何利用Identity模块为用户的查询提供组织架构和用户关系的条件过滤。
