在默认AccountController创建我看到
public AccountController() : this(Startup.UserManagerFactory(),Startup.OAuthOptions.AccessTokenFormat) { }
在Startup.Auth.cs我看到
UserManagerFactory = () => new UserManager<IdentityUser>(new UserStore<IdentityUser>());
看起来像UserStore的实现来自Microsoft.AspNet.Identity.EntityFramework。
所以,要自定义认证,我必须实现我自己的版本的UserStore喜欢
class MYSTUFFUserStore<IdentityUser> : UserStore<IdentityUser> { }
并覆盖方法,然后在Startup.Auth.cs中执行此操作
UserManagerFactory = () => new UserManager<IdentityUser>(new MYSTUFFUserStore<IdentityUser>());
我正在寻找一种正确的方式来自定义身份验证。
解决方法
假设您的表称为AppUser,将您自己的AppUser域对象转换为IUser(使用Microsoft.AspNet.Identity),如下所示
using Microsoft.AspNet.Identity; public class AppUser : IUser { //Existing database fields public long AppUserId { get; set; } public string AppUserName { get; set; } public string AppPassword { get; set; } public AppUser() { this.Id = Guid.NewGuid().ToString(); } [Ignore] public virtual string Id { get; set; } [Ignore] public string UserName { get { return AppUserName; } set { AppUserName = value; } } }
像这样实现UserStore对象
using Microsoft.AspNet.Identity; public class UserStoreService : IUserStore<AppUser>,IUserPasswordStore<AppUser> { CompanyDbContext context = new CompanyDbContext(); public Task CreateAsync(AppUser user) { throw new NotImplementedException(); } public Task DeleteAsync(AppUser user) { throw new NotImplementedException(); } public Task<AppUser> FindByIdAsync(string userId) { throw new NotImplementedException(); } public Task<AppUser> FindByNameAsync(string userName) { Task<AppUser> task = context.AppUsers.Where( apu => apu.AppUserName == userName) .FirstOrDefaultAsync(); return task; } public Task UpdateAsync(AppUser user) { throw new NotImplementedException(); } public void Dispose() { context.Dispose(); } public Task<string> GetPasswordHashAsync(AppUser user) { if (user == null) { throw new ArgumentNullException("user"); } return Task.FromResult(user.AppPassword); } public Task<bool> HasPasswordAsync(AppUser user) { return Task.FromResult(user.AppPassword != null); } public Task SetPasswordHashAsync(AppUser user,string passwordHash) { throw new NotImplementedException(); } }
如果你有自己的自定义密码哈希,你还需要实现IPasswordHasher。下面是一个没有哈希密码的例子(哦不!
using Microsoft.AspNet.Identity; public class MyPasswordHasher : IPasswordHasher { public string HashPassword(string password) { return password; } public PasswordVerificationResult VerifyHashedPassword (string hashedPassword,string providedPassword) { if (hashedPassword == HashPassword(providedPassword)) return PasswordVerificationResult.Success; else return PasswordVerificationResult.Failed; } }
在Startup.Auth.cs中替换
UserManagerFactory = () => new UserManager<IdentityUser>(new UserStore<IdentityUser>());
与
UserManagerFactory = () => new UserManager<AppUser>(new UserStoreService()) { PasswordHasher = new MyPasswordHasher() };
在ApplicationOAuthProvider.cs中,将IdentityUser替换为AppUser
在AccountController.cs中,将IdentityUser替换为AppUser,并删除所有外部验证方法,如GetManageInfo和RegisterExternal等。
