在asp.net core identity中已经有RoleManager，我们只需要封装一下API操作Role即可完成我们角色管理相关功能，这里API打算只提供分页查询，创建以及删除，不提供修改API。
实现RoleManageAppService
IRoleManageAppService
代码语言：javascript复制namespace Wheel.Services.Roles
{
public interface IRoleManageAppService : ITransientDependency
{
Task<Page<RoleDto>> GetRolePageList(PageRequest pageRequest);
Task<R> CreateRole(CreateRoleDto dto);
Task<R> DeleteRole(string roleName);
}
}RoleManageAppService
代码语言：javascript复制namespace Wheel.Services.Roles
{
public class RoleManageAppService : WheelServiceBase, IRoleManageAppService
{
private readonly RoleManager<Role> _roleManager;
private readonly IBasicRepository<Role, string> _roleRepository;
public RoleManageAppService(RoleManager<Role> roleManager, IBasicRepository<Role, string> roleRepository)
{
_roleManager = roleManager;
_roleRepository = roleRepository;
}
public async Task<Page<RoleDto>> GetRolePageList(PageRequest pageRequest)
{
var (items, total) = await _roleRepository.SelectPageListAsync(
a => true,
a => new RoleDto { Id = a.Id, Name = a.Name },
(pageRequest.PageIndex - 1) * pageRequest.PageSize,
pageRequest.PageSize,
pageRequest.OrderBy
);
return new Page<RoleDto>(items, total);
}
public async Task<R> CreateRole(CreateRoleDto dto)
{
var exist = await _roleManager.RoleExistsAsync(dto.Name);
if (exist)
{
throw new BusinessException(ErrorCode.RoleExist, "RoleExist");
}
var result = await _roleManager.CreateAsync(new Role(dto.Name, dto.RoleType));
if(result.Succeeded)
{
return new R();
}
else
{
throw new BusinessException(ErrorCode.CreateRoleError, string.Join("rn", result.Errors.Select(a => a.Description)));
}
}
public async Task<R> DeleteRole(string roleName)
{
var exist = await _roleManager.RoleExistsAsync(roleName);
if (exist)
{
var role = await _roleManager.FindByNameAsync(roleName);
await _roleManager.DeleteAsync(role);
}
else
{
throw new BusinessException(ErrorCode.RoleNotExist, "RoleNotExist");
}
return new R();
}
}
}实现RoleManageController
代码语言：javascript复制namespace Wheel.Controllers
{
/// <summary>
/// 角色管理
/// </summary>
[Route("api/[controller]")]
[ApiController]
public class RoleManageController : WheelControllerBase
{
private readonly IRoleManageAppService _roleManageAppService;
public RoleManageController(IRoleManageAppService roleManageAppService)
{
_roleManageAppService = roleManageAppService;
}
/// <summary>
/// 创建角色
/// </summary>
/// <param name="dto"></param>
/// <returns></returns>
[HttpPost]
public async Task<R> CreateRole(CreateRoleDto dto)
{
return await _roleManageAppService.CreateRole(dto);
}
/// <summary>
/// 删除角色
/// </summary>
/// <param name="roleName"></param>
/// <returns></returns>
[HttpDelete]
public async Task<R> DeleteRole(string roleName)
{
return await _roleManageAppService.DeleteRole(roleName);
}
/// <summary>
/// 角色分页查询
/// </summary>
/// <param name="pageRequest"></param>
/// <returns></returns>
[HttpGet("Page")]
public async Task<Page<RoleDto>> GetRolePageList([FromQuery]PageRequest pageRequest)
{
return await _roleManageAppService.GetRolePageList(pageRequest);
}
}
}非常简单就实现了一个角色管理的API。
