Membership.ValidateUser返回: null
Membership.ValidateUser返回: null

我使用AspNetSqlMembershipProvider创建了一个登录门户
<membership defaultProvider="AspNetSqlMembershipProvider">
<providers>
<remove name="AspNetSqlMembershipProvider"/>
<add name="AspNetSqlMembershipProvider" requiresQuestionAndAnswer="false" enablePasswordRetrieval="false" enablePasswordReset="true" connectionStringName="MembershipDB" minRequiredPasswordLength="8" minRequiredNonalphanumericCharacters="1" applicationName="php" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>但是，我无法使用我创建的用户名和密码登录，我进入代码并找到Membership.ValidateUser返回: null。
以下是代码：
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
bool UserAuthenticated = false;
MembershipProvider AuthenticationProviderUsed = null;
RoleProvider roleProvider = Roles.Providers["SqlRoleProvider"];
// Try authenticating the user against each membership provider
foreach (MembershipProvider membershipProvider in Membership.Providers)
{
try
{
if (membershipProvider.ValidateUser(loginInitial.UserName, loginInitial.Password)) // here got null.
{我查过数据库了。用户名和密码都在那里。谢谢你帮忙。
更新:返回false。
然后MembershipUser user = Membership.GetUser(loginInitial.UserName);用户返回null。
再次更新:更多代码，
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
bool UserAuthenticated = false;
MembershipProvider AuthenticationProviderUsed = null;
RoleProvider roleProvider = Roles.Providers["SqlRoleProvider"];
// Try authenticating the user against each membership provider
foreach (MembershipProvider membershipProvider in Membership.Providers)
{
try
{
if (membershipProvider.ValidateUser(loginInitial.UserName, loginInitial.Password))
{
if (base.ConfigSettings.OperatingMode == ConfigurationSettingValues.OperatingModes.NoAccess)
{
if (!roleProvider.IsUserInRole(loginInitial.UserName, ConfigurationManager.AppSettings["AdminRole"]))
{
FormsAuthentication.SignOut();
return;
}
}
MembershipUser usrInfo = Membership.GetUser(loginInitial.UserName);
if (membershipProvider.Name == "ActiveDirectoryMembershipProvider")
{
System.Web.Security.FormsAuthentication.SetAuthCookie(loginInitial.UserName, loginInitial.RememberMeSet);
UserAuthenticated = true;
AuthenticationProviderUsed = membershipProvider;
break;
}
else
{
Int16 daysSincePwdChange = Convert.ToInt16(DateTime.Now.Subtract(usrInfo.LastPasswordChangedDate).TotalDays);
System.Web.Security.FormsAuthentication.SetAuthCookie(loginInitial.UserName, loginInitial.RememberMeSet);
if (daysSincePwdChange > SecurityUtils.DefaultPasswordExpiryInDays || usrInfo.Comment == "ChangePassword")
{
e.Authenticated = false;
Response.Redirect("~/admin/ChangePassword.aspx?UserName=" + Server.UrlEncode(loginInitial.UserName));
}
else
{
System.Web.Security.FormsAuthentication.SetAuthCookie(loginInitial.UserName, loginInitial.RememberMeSet);
UserAuthenticated = true;
AuthenticationProviderUsed = membershipProvider;
break;
}
}
}
else
{
// See if the user is locked out
MembershipUser user = Membership.GetUser(loginInitial.UserName);
if (user != null && user.IsLockedOut)
{
ErrorMessage.Text = "Your account is currently locked out. Please contact the system administrator.";
}
else
{
ErrorMessage.Text = "Invalid user name and/or password";
//Response.Write("Invalid User Name or Password");
}
}
}
catch (Exception ex)
{
LoggingLibrary.LogException(this.Logger, Context, ex, ex);
}
} 错误消息是：“无效用户名和/或密码”

应该做的第一件事是检查用户是否存在于数据库中。您可能正在使用两个不同的数据库，一个本地数据库和一个用于生产的数据库。您能显示AspNetSqlMembershipProvider的连接字符串吗？
* *我不是连接字符串方面的专家，但在我看来，您运行的是一个sql。我将使用服务器资源管理器从vs或sql管理器连接到数据库，检查aspnet_Users表并验证您的用户是否存在。
你是在本地测试还是在生产机器上测试？如果在生产中，它在当地工作吗？
