如何在DI-ASP.NET Core 2.1中注册自定义UserManager等

Question

我需要创建自己的类来处理EF Core 2.1中的身份。我有以下的，但当想在一个控制器的方法，我得到以下错误

在尝试激活"Sample.API.Models.Identity.Managers.ApplicationUserStore"时，无法解决类型为"Sample.Aneneneba API.Models.Identity.Stores.ApplicationUserStore"的服务。

public void ConfigureServices(IServiceCollection servicesCollection)
{
servicesCollection.AddDbContext<MyIndentityContext>(currentOptions =>
currentOptions.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
servicesCollection.AddIdentity<ApplicationUser, ApplicationRole>()
.AddEntityFrameworkStores<MyIndentityContext>()
.AddRoleStore<ApplicationRoleStore>()
.AddUserStore<ApplicationUserStore>()
.AddUserManager<ApplicationUserManager>()
.AddRoleManager<ApplicationRoleManager>()
.AddSignInManager<ApplicationSignInManager>()
.AddDefaultTokenProviders();
servicesCollection.AddTransient<UserManager<ApplicationUser>, ApplicationUserManager>();
servicesCollection.AddTransient<SignInManager<ApplicationUser>, ApplicationSignInManager>();
servicesCollection.AddTransient<RoleManager<ApplicationRole>, ApplicationRoleManager>();
servicesCollection.AddTransient<IUserStore<ApplicationUser>, ApplicationUserStore>();
servicesCollection.AddTransient<IRoleStore<ApplicationRole>, ApplicationRoleStore>();
...
...

}
public class MyIndentityContext : IdentityDbContext<ApplicationUser, ApplicationRole, string>
{
private readonly IConfiguration _configuration;
private readonly IHttpContextAccessor _httpContextAccessor;
public MyIndentityContext(DbContextOptions dbContextOptions, IHttpContextAccessor httpContextAccessor,
IConfiguration configuration)
: base(dbContextOptions)

_configuration = configuration;

{
base.OnModelCreating(modelBuilder);
modelBuilder.HasDefaultSchema("Sample.API");

public class ApplicationRoleManager : RoleManager<ApplicationRole>

}
public class ApplicationSignInManager : SignInManager<ApplicationUser>
{

}
public class ApplicationUserManager : UserManager<ApplicationUser>

: base(dbContext, identityErrorDescriber)
{}
}
public class ApplicationUser : IdentityUser {}
public class ApplicationRole : IdentityRole
{
public ApplicationRole() { }
public ApplicationRole(string roleName) : base(roleName) { }
public ApplicationRole(string roleName, string roleDescription) : base(roleName)
{
Description = roleDescription;
}
}
[Authorize]
[ApiController]
[Route("api/[controller]")]
[EnableCors(CORS.AllowSpecificOrigins)]
public class UserController : BaseController
{
private readonly ApplicationUserManager _applicationUserManager;
public UserController(ApplicationUserManager applicationUserManager)
{
_applicationUserManager = applicationUserManager;
}
// GET: api/User/5
[HttpGet("{id}")]
public async Task<UserDTO> Get(int id)
{
var currentuser = await _applicationUserManager.FindByNameAsync("NAME");
return ...;
}
}

编辑：

在完成了用户"Camilo Terevinto"推荐的操作后，我成功了，但我也不得不更改所有经理的构造函数。例如，我不得不将ApplicationRoleStore角色存储更改为IRoleStore角色存储

使用依赖注入时，具有依赖关系的类不要求实现，而是要求契约。

此：

private readonly ApplicationUserManager _applicationUserManager;
public UserController(ApplicationUserManager applicationUserManager)
{
_applicationUserManager = applicationUserManager;
}

应该是：

private readonly UserManager<ApplicationUser> _applicationUserManager;
public UserController(UserManager<ApplicationUser> applicationUserManager)
{
_applicationUserManager = applicationUserManager;
}

另外，请注意，您不需要这些行中的任何一行，这些行已经由以前对.AddIdentity及其选项的调用添加。

servicesCollection.AddTransient<UserManager<ApplicationUser>, ApplicationUserManager>();
servicesCollection.AddTransient<SignInManager<ApplicationUser>, ApplicationSignInManager>();
servicesCollection.AddTransient<RoleManager<ApplicationRole>, ApplicationRoleManager>();
servicesCollection.AddTransient<IUserStore<ApplicationUser>, ApplicationUserStore>();
servicesCollection.AddTransient<IRoleStore<ApplicationRole>, ApplicationRoleStore>();
