ASP.NET 核心身份 - 创建用户 "manually" 并提供密码哈希 - 如何正确生成哈希?

ASP.NET Core Identity - Creating user "manually" and providing password hash - How to generate hash correctly?

我必须手动创建用户:

var user = new User
{
    Name = "Joe",
    Email = "test@****.com",
    PasswordHash = "gdfgdfgre2132143xcxzvb=="
}

context.Users.Add(user);

但问题是,当我尝试登录该帐户时,我的密码不起作用。

将我知道密码的用户帐户的密码哈希复制到,然后我将它粘贴到那个新用户并尝试使用相同的密码但它没有用 - password sign in failed

所以我想问 - 我的逻辑有什么问题,我怎样才能让它发挥作用?

是否与 SecurityStamp 有关?

如果要手动添加用户,还应该设置NormalizedUserName 属性。此外,最好使用 IPasswordHasher<TUser> Interface 来散列密码:

注入的服务:

private readonly ApplicationDbContext _context;
public readonly IPasswordHasher<IdentityUser> _passwordHasher;

public HomeController( ApplicationDbContext dbContext, IPasswordHasher<IdentityUser> _passwordHasher)
{

    this._context = dbContext;
    this._passwordHasher = _passwordHasher;

}

我假设你的 User 继承了 IdentityUser ,这里我使用 IdentityUser 例如:

IdentityUser applicationUser = new IdentityUser();
Guid guid = Guid.NewGuid();
applicationUser.Id = guid.ToString();
applicationUser.UserName = "Joe";
applicationUser.Email = "wx@hotmail.com";
applicationUser.NormalizedUserName = "wx@hotmail.com";

_context.Users.Add(applicationUser);


var hashedPassword = _passwordHasher.HashPassword(applicationUser, "YourPassword");
applicationUser.SecurityStamp = Guid.NewGuid().ToString();
applicationUser.PasswordHash = hashedPassword;

_context.SaveChanges();

您还可以使用 UserManager.CreateAsync 使用给定密码在后备存储中创建指定用户:

var user = new IdentityUser { UserName = "Joe", Email = "wx@hotmail.com" };
var result = await _userManager.CreateAsync(user, "YourPassWord");
if (result.Succeeded)
{

}

注意:您应该在登录时提供 Email 值。
