微软正在推出一个名为ASP.NET Identity的新会员系统(也是ASP.NET MVC 5中的默认系统).我找到了示例项目,但是没有实现密码重置.
在密码重置主题上找到了这篇文章:使用一个ASP.NET身份实现用户确认和密码重置 - 痛苦或愉快,对我没有帮助,因为不使用内置密码恢复.
当我查看选项时,我认为我们需要生成一个重置令牌,我将发送给用户.用户可以使用令牌设置新密码,覆盖旧密码.
我找到了IdentityManager.Passwords.GenerateResetPasswordToken/ IdentityManager.Passwords.GenerateResetPasswordTokenAsync(string tokenId, string userName, validUntilUtc),但我无法弄清楚它可能意味着什么tokenId参数.
如何使用MVC 5.0在ASP.NET中实现密码重置?
我明白了:tokenid是一个自由选择的身份,它标识了一个密码选项.例如,
1.看起来像密码恢复过程,第1步 (它基于:https://stackoverflow.com/a/698879/208922)
[HttpPost]
[ValidateAntiForgeryToken]
[AllowAnonymous]
//[RecaptchaControlMvc.CaptchaValidator]
public virtual async Task<ActionResult> ResetPassword(
ResetPasswordViewModel rpvm)
{
string message = null;
//the token is valid for one day
var until = DateTime.Now.AddDays(1);
//We find the user, as the token can not generate the e-mail address,
//but the name should be.
var db = new Context();
var user = db.Users.SingleOrDefault(x=>x.Email == rpvm.Email);
var token = new StringBuilder();
//Prepare a 10-character random text
using (RNGCryptoServiceProvider
rngCsp = new RNGCryptoServiceProvider())
{
var data = new byte[4];
for (int i = 0; i < 10; i++)
{
//filled with an array of random numbers
rngCsp.GetBytes(data);
//this is converted into a character from A to Z
var randomchar = Convert.ToChar(
//produce a random number
//between 0 and 25
BitConverter.ToUInt32(data, 0) % 26
//Convert.ToInt32('A')==65
+ 65
);
token.Append(randomchar);
}
}
//This will be the password change identifier
//that the user will be sent out
var tokenid = token.ToString();
if (null!=user)
{
//Generating a token
var result = await IdentityManager
.Passwords
.GenerateResetPasswordTokenAsync(
tokenid,

until
);
if (result.Success)

//send the email

}
}
message =
"We have sent a password reset request if the email is verified.";
return RedirectToAction(
MVC.Account.ResetPasswordWithToken(
token: string.Empty,
message: message
)
);

2然后当用户输入令牌和新密码时:
[HttpPost]
[ValidateAntiForgeryToken]
[AllowAnonymous]
//[RecaptchaControlMvc.CaptchaValidator]
public virtual async Task<ActionResult> ResetPasswordWithToken(
ResetPasswordWithTokenViewModel
rpwtvm
)
{
if (ModelState.IsValid)
{
string message = null;
//reset the password
var result = await IdentityManager.Passwords.ResetPasswordAsync(
rpwtvm.Token,
rpwtvm.Password
);
if (result.Success)
{
message = "the password has been reset.";
return RedirectToAction(
MVC.Account.ResetPasswordCompleted(message: message)
);
}
else
{
AddErrors(result);
}
}
return View(MVC.Account.ResetPasswordWithToken(rpwtvm));
}

在github上对项目进行示例的骷髅提议,如果有人需要它可能会被测试.电子邮件发送尚未写入,可能很快就会添加.
好像很麻烦......上面给出了什么好处:
有了这个流程,您在任何时候都不会从您的域名中发送密码.
请任何人向我证明这是不安全的.
