如何配置PasswordHasher<T>？

public void ConfigureServices(IServiceCollection services)
{
    // 其他服务的注册

    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

    // 其他服务的配置
}

private readonly UserManager<ApplicationUser> _userManager;
private readonly PasswordHasher<ApplicationUser> _passwordHasher;

public YourClass(UserManager<ApplicationUser> userManager, PasswordHasher<ApplicationUser> passwordHasher)
{
    _userManager = userManager;
    _passwordHasher = passwordHasher;
}

// 哈希密码
string hashedPassword = _passwordHasher.HashPassword(user, password);

// 验证密码
PasswordVerificationResult result = _passwordHasher.VerifyHashedPassword(user, hashedPassword, providedPassword);

if (result == PasswordVerificationResult.Success)
{
    // 密码验证成功
}
else
{
    // 密码验证失败
}
