如何重写 createUser() ASP .NET Membership 方法来显示自定义错误消息？
如何重写 createUser() 会员方法以在密码检查失败时显示自定义错误消息？
我使用了网站管理工具，它提供了一个类似向导的界面来创建新用户。 （要启动此工具，请单击 Microsoft Visual Studio 中网站菜单上的 ASP.NET 配置）
Web.Config 文件：
<membership defaultProvider="MyMembershipProvider">
<providers>
<clear />
<add name="MyMembershipProvider" type="BlueDDApp.Controllers.MyMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" minRequiredPasswordLength="8" minRequiredNonalphanumericCharacters="0" passwordStrengthRegularExpression="^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])|(?=.*[a-z])(?=.*[A-Z])(?=.*[!%,.;:])|(?=.*[a-z])(?=.*[0-9])(?=.*[!%,.;:])|(?=.*[A-Z])(?=.*[0-9])(?=.*[!%,.;:])$" passwordAttemptWindow="10" applicationName="/" />
</providers>
</membership>
自定义会员等级::
public class MyMembershipProvider : SqlMembershipProvider
{
public MyMembershipProvider()
{
//Membership.ValidatingPassword += new MembershipValidatePasswordEventHandler(OnValidatePassword);
ValidatingPassword += ValidatePassword;
}
/* public override MembershipUser CreateUser( string username, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, object providerUserKey, out MembershipCreateStatus status)
{
ValidatingPassword += ValidatePassword;
return base.CreateUser(username, password, email, passwordQuestion, passwordAnswer, isApproved, providerUserKey, out status);
}*/
void ValidatePassword(object sender, ValidatePasswordEventArgs e)
{
Regex check = new Regex("^(?i)(?!.*" + e.UserName + ").*$");
if (!check.IsMatch(e.Password))
{
e.FailureInformation = new HttpException("blah blah");
e.Cancel = true;
}
}
}
How to Override createUser() Membership method to display custom error message when password check fails??
I Used the Web Site Administration Tool, which provides a wizard-like interface for creating new users. (To start this tool, click ASP.NET Configuration on the Website menu in the Microsoft Visual Studio)
Web.Config file:
<membership defaultProvider="MyMembershipProvider">
<providers>
<clear />
<add name="MyMembershipProvider" type="BlueDDApp.Controllers.MyMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" minRequiredPasswordLength="8" minRequiredNonalphanumericCharacters="0" passwordStrengthRegularExpression="^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])|(?=.*[a-z])(?=.*[A-Z])(?=.*[!%,.;:])|(?=.*[a-z])(?=.*[0-9])(?=.*[!%,.;:])|(?=.*[A-Z])(?=.*[0-9])(?=.*[!%,.;:])$" passwordAttemptWindow="10" applicationName="/" />
</providers>
</membership>
Custom Membership class::
public class MyMembershipProvider : SqlMembershipProvider
{
public MyMembershipProvider()
{
//Membership.ValidatingPassword += new MembershipValidatePasswordEventHandler(OnValidatePassword);
ValidatingPassword += ValidatePassword;
}
/* public override MembershipUser CreateUser( string username, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, object providerUserKey, out MembershipCreateStatus status)
{
ValidatingPassword += ValidatePassword;
return base.CreateUser(username, password, email, passwordQuestion, passwordAnswer, isApproved, providerUserKey, out status);
}*/
void ValidatePassword(object sender, ValidatePasswordEventArgs e)
{
Regex check = new Regex("^(?i)(?!.*" + e.UserName + ").*$");
if (!check.IsMatch(e.Password))
{
e.FailureInformation = new HttpException("blah blah");
e.Cancel = true;
}
}
}

如果您使用的是 asp:CreateUserWizard 控件（我认为您使用的是 asp:CreateUserWizard 控件）（它将从您的 web.config 连接到会员资格提供程序），那么：
在设计模式下，如果您单击此控件，在右上角您会看到一个图标，类似箭头，您可以在其中选择“自定义创建用户步骤”选项。这将转换该控件，将其扩展为在内部使用的单独控件。现在，您可以访问错误消息（文字控件）并将其更改为显示静态消息，或显示代码中动态更改的消息。
您还可以向 CreateUserWizard 添加事件，例如 CreateUser、CreateUserError 和 CreatedUser，这将允许您自定义行为以及如何使用创建的内容。
If you are using asp:CreateUserWizard control, which I presume you are ( it will connect to a membership provider from your web.config ), then :
In Design mode, if you click on this control, in the top right corner you have an icon, sort of an arrow, and there you can choose "Customize Create User Step" option. This will transform the control, expanding it into a separate controls that are used inside. Now you can access error message ( Literal control ) and change it to display static message, or display dynamically changing messages from code.
You can also add events to the CreateUserWizard like CreatingUser, CreateUserError and CreatedUser which will let you customize the behavior and how the creation is being used even more.
以下是关于自定义 MembershipUser 的一个很好的示例：
