如何在新的ASP.NET身份验证系统中获取用户密码?或者在不知道当前密码的情况下重置密码(用户忘记密码)?
如何在新的ASP.NET身份验证系统中获取用户密码?或者在不知道当前密码的情况下重置密码(用户忘记密码)?
string resetToken = await UserManager.GeneratePasswordResetTokenAsync(model.Id);
IdentityResult passwordChangeResult = await UserManager.ResetPasswordAsync(model.Id, resetToken, model.NewPassword);
当前版本
假设您已经处理了重置忘记密码请求的验证,使用以下代码作为示例代码步骤。
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 Nightly Build 中
框架已更新以使用 Token 处理请求,例如忘记密码。一旦发布,预计会提供简单的代码指导。
更新:
此更新仅提供更明确的步骤。
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);
这是原始答案。它可以运行,但存在问题。如果AddPassword
失败了怎么办?用户将没有密码。
原始答案:我们可以使用三行代码:
UserManager<IdentityUser> userManager =
new UserManager<IdentityUser>(new UserStore<IdentityUser>());
userManager.RemovePassword(userId);
userManager.AddPassword(userId, newPassword);

最好使用EdwardBrey提出的答案,然后再参考DanielWright给出的代码示例。
ChangePassword
方法,要么使用现有的 AddPassword
并不断尝试直到成功。 - Shaun Luttin在您的UserManager
上,首先调用GeneratePasswordResetTokenAsync。 一旦用户验证了自己的身份(例如通过电子邮件接收到令牌),将其传递给ResetPasswordAsync。
ResetPasswordAsync
接受用户 ID 的优点是,身份提供者只需要索引用户 ID,而不必还索引令牌。如果有许多用户,它可以更好地扩展。 - Edward Brey在使用Web API时,重置Asp.Net Core Identity密码的最佳方法。
注意*: Error()和Result()是为内部使用而创建的。您可以返回您想要的内容。
[HttpPost]
[Route("reset-password")]
public async Task<IActionResult> ResetPassword(ResetPasswordModel model)

return BadRequest(ModelState);
try
{
if (model is null)
return Error("No data found!");
var user = await _userManager.FindByIdAsync(AppCommon.ToString(GetUserId()));
if (user == null)
return Error("No user found!");
Microsoft.AspNetCore.Identity.SignInResult checkOldPassword =
await _signInManager.PasswordSignInAsync(user.UserName, model.OldPassword, false, false);
if (!checkOldPassword.Succeeded)
return Error("Old password does not matched.");
string resetToken = await _userManager.GeneratePasswordResetTokenAsync(user);
if (string.IsNullOrEmpty(resetToken))
return Error("Error while generating reset token.");
var result = await _userManager.ResetPasswordAsync(user, resetToken, model.Password);

Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
。如果您没有相同的OwinContext,您需要创建一个新的DataProtectorTokenProvider
就像OwinContext
使用的那样。默认情况下,查看App_Start -> IdentityConfig.cs
。应该类似于 new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
。[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);
}
使用 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);
}
DpapiDataProtectionProvider
和DataProtectorTokenProvider
需要使用相同的名称进行创建,才能使重置密码工作。如果使用Owin创建密码重置令牌,然后使用另一个名称创建新的DpapiDataProtectionProvider
将不起作用。
我在ASP.NET Identity中使用的代码:

var user = await UserManager.FindByEmailAsync(email);
if (user == null)

// 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);

以下代码片段取自AspNetIdentitySample项目,可在Github上获得
。UserManager<TUser, TKey>
中创建方法。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);
}
我进行了一些调查,对我有效的解决方案是在这篇文章中找到的几个解决方案的混合体。
基本上我正在编译这个解决方案并发布我所使用的内容。在我的情况下,我不想使用任何来自 .net core 的令牌。
public async Task ResetPassword(string userId, string password)
{
var user = await _userManager.FindByIdAsync(userId);
var hashPassword= _userManager.PasswordHasher.HashPassword(user, password);
user.PasswordHash = passwordHash;
await _userManager.UpdateAsync(user);
}
SecurityStamp
不为null。这可能发生在从其他数据库迁移的用户或未通过UserManager.CreateAsync()
方法创建的用户上。 - Alisson Reinaldo Silva
