是否可以在通用存储库模式中使用asp net core的默认身份验证?如果可以,如何使用?
我能够为我的所有代码创建一个使用通用存储库模式的项目,但使用默认方式的项目的身份验证方除外。
我的存储库看起来像:
using System.Linq;
using DemoWebsite.Interfaces;
using Microsoft.EntityFrameworkCore;
namespace DemoWebsite.Data
{
public class Repository<T> : IRepository<T> where T : class
{
protected readonly DbContext Context;
protected DbSet<T> DbSet;
public Repository(ApplicationDbContext context)
{
Context = context;
DbSet = context.Set<T>();
}
public void Add(T entity)
{
Context.Set<T>().Add(entity);
Save();
}
public T Get<TKey>(TKey id)
{
return DbSet.Find(id);
}
public IQueryable<T> GetAll()
{
return DbSet;
}
public void Update(T entity)
{
Save();
}
private void Save()
{
Context.SaveChanges();
}
}
}
我的ApplicationDbContext类:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);
}
}

是的,这是可能的,但要做到这一点需要付出相当大的努力。您必须实施IUserStore
,可能IRoleStore
(接口here和here)。
实现此接口时,还必须实现所有功能接口(用于获取密码,双因素身份验证(here),安全戳等)。
对于示例实现,您始终可以查看EF Core Identity provider的来源。
喜欢这个
public abstract class UserStore<TUser, TRole, TContext, TKey, TUserClaim, TUserRole, TUserLogin, TUserToken, TRoleClaim> :
IUserLoginStore<TUser>,
IUserRoleStore<TUser>,
IUserClaimStore<TUser>,
IUserPasswordStore<TUser>,
IUserSecurityStampStore<TUser>,
IUserEmailStore<TUser>,
IUserLockoutStore<TUser>,
IUserPhoneNumberStore<TUser>,
IQueryableUserStore<TUser>,
IUserTwoFactorStore<TUser>,
IUserAuthenticationTokenStore<TUser>
where TUser : IdentityUser<TKey, TUserClaim, TUserRole, TUserLogin>
where TRole : IdentityRole<TKey, TUserRole, TRoleClaim>
where TContext : DbContext
where TKey : IEquatable<TKey>
where TUserClaim : IdentityUserClaim<TKey>
where TUserRole : IdentityUserRole<TKey>
where TUserLogin : IdentityUserLogin<TKey>
where TUserToken : IdentityUserToken<TKey>
where TRoleClaim : IdentityRoleClaim<TKey>
{
...
}
您的用户商店可能如下所示:
public class GenericUserStore<TUser> : IUserStore<TUser>,
IUserPasswordStore<TUser> where TUser : ApplicationUser
{
public GenericUserStore(IRepository<TUser> userRepo) { }
public Task<TUser> FindByIdAsync(string userId, CancellationToken cancellationToken)
{
return userRepo.Get(userId);
}
...
}
和RoleStore
相同。然后最后用您自己的注册表替换EF提供者注册(EF here的来源)。
userStoreType = typeof(GenericUserStore<,,,>).MakeGenericType(userType, roleType, contextType, keyType);
roleStoreType = typeof(GenericRoleStore<,,>).MakeGenericType(roleType, contextType, keyType);
var services = new ServiceCollection();
services.AddScoped(
typeof(IUserStore<>).MakeGenericType(userType),
userStoreType);
services.AddScoped(
typeof(IRoleStore<>).MakeGenericType(roleType),
roleStoreType);
然后UserManager
和其他Identity类将使用您的用户/角色存储。但除非你有一个无法映射到EF /已知提供商的现有数据库结构,否则它的价值就更大了。
