我有以下代码，用于在用户单击密码重置按钮时更改用户的密码（包含一些额外的代码来记录到 ELMAH 中，以便我可以尝试找出哪里出了问题）。
这是在 ASP.NET MVC 2 中使用标准 aspnet 成员资格提供程序，使用以下简单的视图：
New Password: ______
Confirm Password: ______
[Reset] [Cancel]
这个视图的路由是/Account/Reset/guid，其中guid是aspnet会员数据库中用户的id。
代码的关键部分在于调用 user.ChangePassword()。你可以看到，当成功时，它会记录一条消息。问题在于对于某些用户，成功消息被记录了，但他们无法使用新密码登录。而对于其他用户，记录了成功消息并且他们可以登录。
if (user.ChangePassword(pwd, confirmPassword))
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - changed successfully!"));
return Json(new {
Msg = "You have reset your password successfully." },
JsonRequestBehavior.AllowGet);
}
完整的代码清单如下：
[HttpPost]
public JsonResult ResetPassword(string id, string newPassword, string confirmPassword)
{
ErrorSignal.FromCurrentContext().Raise(new Exception("ResetPassword started for " + id));
ViewData["PasswordLength"] = Membership.MinRequiredPasswordLength;
if (string.IsNullOrWhiteSpace(newPassword))
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - new password was blank."));
ModelState.AddModelError("_FORM", "Please enter a new password.");
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
if (newPassword.Length < Membership.MinRequiredPasswordLength)
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - new password was less than minimum length."));
ModelState.AddModelError("_FORM",
string.Format("The password must be at least {0} characters long.",
Membership.MinRequiredPasswordLength));
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
if (string.IsNullOrWhiteSpace(confirmPassword))
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - confirm password was blank."));
ModelState.AddModelError("_FORM",
"Please enter the same new password in the confirm password textbox.");
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
if (confirmPassword.Length < Membership.MinRequiredPasswordLength)
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - confirm password was less than minimum length."));
ModelState.AddModelError("_FORM",
string.Format("The password must be at least {0} characters long.",
Membership.MinRequiredPasswordLength));
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
if (confirmPassword != newPassword)
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - new password did not match the confirm password."));
ModelState.AddModelError("_FORM", "Please enter the same password again.");
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
bool isMatch = ValidationHelper.IsGUID(id);
if (string.IsNullOrWhiteSpace(id) || !isMatch)
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - id was not a guid."));
ModelState.AddModelError("_FORM", "An invalid ID value was passed in through the URL");
}
else
{
//ID exists and is kosher, see if this user is already approved
//Get the ID sent in the querystring
Guid userId = new Guid(id);
try
{
//Get information about the user
MembershipUser user = Membership.GetUser(userId);
if (user == null)
{
//could not find the user
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - could not find user by id " + id));
ModelState.AddModelError("_FORM",
"The user account can not be found in the system.");
}
else
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - user is " + user.UserName));
string pwd = user.ResetPassword();
if (user.ChangePassword(pwd, confirmPassword))
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - changed successfully!"));
return Json(new {
Msg = "You have reset your password successfully." },
JsonRequestBehavior.AllowGet);
}
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword
- failed to change the password, for an unknown reason"));
}
}
catch (Exception ex)
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword: " + ex));
return Json(new { Error = ex.Message + " -> "
+ ex.InnerException.Message }, JsonRequestBehavior.AllowGet);
}
}
return Json(new { Errors = ModelState.Errors() }, JsonRequestBehavior.AllowGet);
}
编辑：添加悬赏以尝试解决此问题。这是我的问题清单中最烦人的问题之一，我不知道该如何继续。
