我需要＆＃34;超级用户＆＃34;能够更改身份系统中任何用户的密码。我检查了两个解决方案。
1）将这个重载函数添加到CustomUserManager for CRUD：
public async Task<IdentityResult> ChangePasswordAsync(TenantUser user, string newPassword)
{...}
使用具有令牌参数的原始函数，但控制器中的此功能不起作用并返回无效令牌：
string Token = await manager.GeneratePasswordResetTokenAsync(TenantUser);
var resultPasswordChange = await manager.ResetPasswordAsync(TenantUser, Token, model.TenantUsersPassword.Password);
自定义用户管理器：所有PRIVATE功能和参数已从orig UserManager复制到派生的CustomUserManager。 NotSupportedException的资源仍然无法使用...我对结果不满意...... 你能帮助我吗？什么是更好的？实现CustomUserManager或解决无效令牌错误？请问该怎么做？
示例您需要复制多一个函数（ChangePasswordAsync）：
namespace Program.Models
{
public class TenantUserManager<TenantUser> : UserManager<TenantUser>, IDisposable where TenantUser : class
{
// protected const string ResetPasswordTokenPurpose = "ResetPassword";
// protected const string ConfirmEmailTokenPurpose = "EmailConfirmation";
private TimeSpan _defaultLockout = TimeSpan.Zero;
private bool _disposed;
private readonly HttpContext _context;
private CancellationToken CancellationToken => _context?.RequestAborted ?? CancellationToken.None;
