我正在設置一個asp.net web api 2應用程序，並且我在自定義Identity.UserManager驗證用戶密碼時遇到問題。當我嘗試驗證用戶的哈希密碼時，它總是返回失敗！即使我知道我提供了正確的密碼。這裏我試圖驗證一個用戶並向該用戶返回一個令牌。用戶數據表（DVUsers）存儲在MySQL數據庫中。我懷疑我的問題是如何將密碼哈希存儲在mysql中。ASP.net Identity UserManager未驗證密碼
從一開始，我的授權服務器Proivder：
public class AuthServerProvider : OAuthAuthorizationServerProvider
{
public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
try
{
AuthContext _ctx = new AuthContext();
DVUserManager userManager = new DVUserManager(_ctx);
AuthRepo _repo = new AuthRepo(userManager, _ctx);
DVUser user = await _repo.FindUser(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
identity.AddClaim(new Claim("sub", context.UserName));
identity.AddClaim(new Claim("role", "user"));
context.Validated(identity);
}
catch (Exception ex)
{
context.SetError("invalid_grant", "message");
}
}
}
現在，這裏是我的AuthRepo類。 VerifyHashedPsssword始終在方法FindUser中返回失敗。
public class AuthRepo : IDisposable
{
private AuthContext _ctx;
private DVUserManager _userManager;
public AuthRepo(DVUserManager userManager, AuthContext ctx)
{
_ctx = ctx;
_userManager = userManager;
}
public async Task<IdentityResult> RegisterUser(DVUser user)
{
DVUser iuser = new DVUser { UserName = user.UserName};
var result = await _userManager.CreateAsync(iuser, user.UserName);
return result;
}
public async Task<DVUser> FindUser(string userName, string Password)
{
//Find the user works fine, it finds the correct user
DVUser user = await _userManager.FindByNameAsync(userName);
//compare passwords. VerifyHasedPAssword ALWAYS is returning failed
PasswordVerificationResult result = _userManager.PasswordHasher.VerifyHashedPassword(user.Password, Password);
if (result == PasswordVerificationResult.Success) { return user; }
else { return null; }
}
public void Dispose()
{
_ctx.Dispose();
_userManager.Dispose();
}
}
你可能想看到我的支持類。
public class AuthContext : IdentityDbContext<IdentityUser>
{
public AuthContext() : base("localhost") //name of the data connection to use
{
}
public DbSet<DVUser> DVUsers { get; set; }
}
我的自定義用戶經理
public class DVUserManager : UserManager<DVUser>
{
public DVUserManager(AuthContext ctx) : base(new DVUserStore(ctx))
{
PasswordValidator = new MinimumLengthValidator(4);
}
}
這裏是實現IUSER
public class DVUser : IUser
{
public string Id
{
get; set;
}
public string UserName
{
get; set;
}
public string Password { get; set; }
public int DVClientID { get; set; }
}
最後我的客戶UserStore
public class DVUserStore : IUserStore<DVUser>, IUserPasswordStore<DVUser>
{
AuthContext _context;
public DVUserStore(AuthContext context)
{
_context = context;
}
public Task CreateAsync(DVUser user)
{
user.Id = Guid.NewGuid().ToString();
_context.DVUsers.Add(user);
return _context.SaveChangesAsync();
}
public Task DeleteAsync(DVUser user)
{
throw new NotImplementedException();
}
public void Dispose()
{
_context.Dispose();
}
public Task<DVUser> FindByIdAsync(string userId)
{
throw new NotImplementedException();
}
public Task<DVUser> FindByNameAsync(string userName)
{
Task<DVUser> task = _context.DVUsers.Where(
apu => apu.UserName == userName)
.FirstOrDefaultAsync();
return task;
}
public Task<string> GetPasswordHashAsync(DVUser user)
{
if (user == null)
{
throw new ArgumentNullException("user");
}
return Task.FromResult(user.Password);
}
public Task<bool> HasPasswordAsync(DVUser user)
{
return Task.FromResult(user.Password != null);
}
public Task SetPasswordHashAsync(DVUser user, string passwordHash)
{
return Task.FromResult(user.Password = passwordHash);
}
public Task UpdateAsync(DVUser user)
{
throw new NotImplementedException();
}
}
MySQL表，DVUsers看起來DVUser像t他的。 DVUsers Table, UTF8 encoding
這是DVUsers中的數據。有一個用戶 DVUsers table data
感謝您的任何幫助！
