我怎样才能得到用户的新ASP.NET识别系统的密码？ 或者我怎么可以重置不知道目前的一个（用户忘记密码）？

Answer 1:

在当前版本中

假设你已经处理重置遗忘的密码要求的验证，使用下面的代码作为示例代码的步骤。 

ApplicationDbContext =new ApplicationDbContext()
String userId = "<YourLogicAssignsRequestedUserId>";
String newPassword = "<PasswordAsTypedByUser>";
ApplicationUser cUser = UserManager.FindById(userId);
String hashedNewPassword = UserManager.PasswordHasher.HashPassword(newPassword);
UserStore<ApplicationUser> store = new UserStore<ApplicationUser>();            
store.SetPasswordHashAsync(cUser, hashedNewPassword);

在ASPNET每日构建

该框架被更新与令牌的工作来处理像忘记的请求。 一旦发布，简单的代码的指导预期。

更新：

此更新只是提供更清晰的步骤。 

ApplicationDbContext context = new ApplicationDbContext();
UserStore<ApplicationUser> store = new UserStore<ApplicationUser>(context);
UserManager<ApplicationUser> UserManager = new UserManager<ApplicationUser>(store);
String userId = User.Identity.GetUserId();//"<YourLogicAssignsRequestedUserId>";
String newPassword = "test@123"; //"<PasswordAsTypedByUser>";
String hashedNewPassword = UserManager.PasswordHasher.HashPassword(newPassword);                    
ApplicationUser cUser = await store.FindByIdAsync(userId);
await store.SetPasswordHashAsync(cUser, hashedNewPassword);
await store.UpdateAsync(cUser);


Answer 2:

或者我怎么可以重置不知道目前的一个（用户忘记密码）？

如果你想使用的UserManager更改密码，但你不希望提供用户的当前密码，您可以生成一个密码重置令牌，然后使用它，而不是马上。 

string resetToken = await UserManager.GeneratePasswordResetTokenAsync(model.Id);
IdentityResult passwordChangeResult = await UserManager.ResetPasswordAsync(model.Id, resetToken, model.NewPassword);


Answer 3:

弃用

这是原来的答案。 它的工作，但有一个问题。 如果AddPassword失败了呢？ 用户也就没有了密码。

原来的答案：我们可以用三行代码： 

UserManager<IdentityUser> userManager = 
    new UserManager<IdentityUser>(new UserStore<IdentityUser>());

userManager.RemovePassword(userId);

userManager.AddPassword(userId, newPassword);

参见： http://msdn.microsoft.com/en-us/library/dn457095(v=vs.111).aspx

现在推荐

这可能是更好的使用，答案EdwardBrey建议 ，然后DanielWright后来阐述了代码示例。



Answer 4:

在您UserManager ，首先调用GeneratePasswordResetTokenAsync 。 一旦用户已经（由接收电子邮件令牌例如）证实自己的身份，通过该令牌ResetPasswordAsync 。



Answer 5:

string message = null;
//reset the password
var result = await IdentityManager.Passwords.ResetPasswordAsync(model.Token, model.Password);
if (result.Success)
{
    message = "The password has been reset.";
    return RedirectToAction("PasswordResetCompleted", new { message = message });
}
else
{
    AddErrors(result);
}

下面这段代码被取出AspNetIdentitySample项目可在github上



Answer 6:

在创建方法UserManager<TUser, TKey> 

public Task<IdentityResult> ChangePassword(int userId, string newPassword)
{
     var user = Users.FirstOrDefault(u => u.Id == userId);
     if (user == null)
          return new Task<IdentityResult>(() => IdentityResult.Failed());

     var store = Store as IUserPasswordStore<User, int>;
     return base.UpdatePassword(store, user, newPassword);
}


Answer 7:

在密码重置的情况下，建议通过发送密码重置令牌注册用户的电子邮件将其复位，并要求用户提供新的密码。 如果已经创建了具有默认配置settins身份框架易于使用.NET库。 你可以找到在细节博客链接和源代码在github上。



Answer 8:

我认为微软指南ASP.NET身份是一个良好的开端。

https://docs.microsoft.com/en-us/aspnet/identity/overview/features-api/account-confirmation-and-password-recovery-with-aspnet-identity

注意：

如果你不使用的AccountController和wan't重置您的密码，使用Request.GetOwinContext().GetUserManager<ApplicationUserManager>(); 。 如果你不具有相同的OwinContext你需要创建一个新的DataProtectorTokenProvider像一个OwinContext使用。 默认情况下，看看App_Start -> IdentityConfig.cs 。 应该看起来像new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity")); 。

可以这样创建：

无Owin： 

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));

    var email = "test@test.com";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));
    var email = "test@test.com";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

随着Owin： 

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "test@test.com";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "test@test.com";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

该DpapiDataProtectionProvider和DataProtectorTokenProvider需要使用相同的名称创建的密码重设工作。 使用Owin用于创建密码重置令牌，然后创建一个新的DpapiDataProtectionProvider使用其他名称将无法正常工作。

我使用的ASP.NET身份代码：

Web.Config中： 

<add key="AllowedHosts" value="example.com,example2.com" />

AccountController.cs： 

[Route("RequestResetPasswordToken/{email}/")]
[HttpGet]
[AllowAnonymous]
public async Task<IHttpActionResult> GetResetPasswordToken([FromUri]string email)
{
    if (!ModelState.IsValid)
        return BadRequest(ModelState);

    var user = await UserManager.FindByEmailAsync(email);
    if (user == null)
    {
        Logger.Warn("Password reset token requested for non existing email");
        // Don't reveal that the user does not exist
        return NoContent();
    }

    //Prevent Host Header Attack -> Password Reset Poisoning. 
    //If the IIS has a binding to accept connections on 80/443 the host parameter can be changed.
    //See https://security.stackexchange.com/a/170759/67046
    if (!ConfigurationManager.AppSettings["AllowedHosts"].Split(',').Contains(Request.RequestUri.Host)) {
            Logger.Warn($"Non allowed host detected for password reset {Request.RequestUri.Scheme}://{Request.Headers.Host}");
            return BadRequest();
    }

    Logger.Info("Creating password reset token for user id {0}", user.Id);

    var host = $"{Request.RequestUri.Scheme}://{Request.Headers.Host}";
    var token = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
    var callbackUrl = $"{host}/resetPassword/{HttpContext.Current.Server.UrlEncode(user.Email)}/{HttpContext.Current.Server.UrlEncode(token)}";

    var subject = "Client - Password reset.";
    var body = "<html><body>" +
               "<h2>Password reset</h2>" +
               $"<p>Hi {user.FullName}, <a href=\"{callbackUrl}\"> please click this link to reset your password </a></p>" +
               "</body></html>";

    var message = new IdentityMessage
    {
        Body = body,
        Destination = user.Email,
        Subject = subject
    };

    await UserManager.EmailService.SendAsync(message);

    return NoContent();
}

[HttpPost]
[Route("ResetPassword/")]
[AllowAnonymous]
public async Task<IHttpActionResult> ResetPasswordAsync(ResetPasswordRequestModel model)
{
    if (!ModelState.IsValid)
        return NoContent();

    var user = await UserManager.FindByEmailAsync(model.Email);
    if (user == null)
    {
        Logger.Warn("Reset password request for non existing email");
        return NoContent();
    }            

    if (!await UserManager.UserTokenProvider.ValidateAsync("ResetPassword", model.Token, UserManager, user))
    {
        Logger.Warn("Reset password requested with wrong token");
        return NoContent();
    }

    var result = await UserManager.ResetPasswordAsync(user.Id, model.Token, model.NewPassword);

    if (result.Succeeded)
    {
        Logger.Info("Creating password reset token for user id {0}", user.Id);

        const string subject = "Client - Password reset success.";
        var body = "<html><body>" +
                   "<h1>Your password for Client was reset</h1>" +
                   $"<p>Hi {user.FullName}!</p>" +
                   "<p>Your password for Client was reset. Please inform us if you did not request this change.</p>" +
                   "</body></html>";

        var message = new IdentityMessage
        {
            Body = body,
            Destination = user.Email,
            Subject = subject
        };

        await UserManager.EmailService.SendAsync(message);
    }

    return NoContent();
}

public class ResetPasswordRequestModel
{
    [Required]
    [Display(Name = "Token")]
    public string Token { get; set; }

    [Required]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 10)]
    [DataType(DataType.Password)]
    [Display(Name = "New password")]
    public string NewPassword { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm new password")]
    [Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }
}
