Question

我有一个CreateUserWizard，供用户注册新帐户。

我添加了文本字段和必填字段验证器

然而，当我点击带有空用户名的注册按钮时，我收到错误：

异常详细信息：System.ArgumentException：成员的用户名必须与emptry字符串不同

参数名称：loginName

用户名字段有其requiredfieldvalidator，因此它应该有效。我还添加了

UserNameRequiredErrorMessage

向导的属性，但它没有什么区别。

上面的错误消息中提到的

loginName 是LoginView的控件。我在同一页面上有这个，但在注册CreateUserWizard时没有使用它。

为什么会这样？

我的代码：

<asp:Panel ID="pnlRegister" runat="server">

<asp:CreateUserWizard ID="cuwRegister" RequireEmail="false"
OnContinueButtonClick="cuwRegister_ContinueButtonClick" 
    OnCreatedUser="cuwRegister_CreatedUser"

            </asp:CreateUserWizardStep>
    <asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server"></asp:CompleteWizardStep>
</WizardSteps>

并在后面的代码中：

protected void cuwRegister_CreatedUser(object sender, EventArgs e)
{
    string email = cuwRegister.UserName;
    string username = cuwRegister.UserName;
    string password = cuwRegister.Password;
    Page.Validate("CreateUserWizard");
    if(Page.IsValid)
        CreateUser(email, username, password);
}

protected void Page_Load(object sender, EventArgs e)
{
    btnRegister.Text = cuwRegister.CreateUserButtonText = umbraco.library.GetDictionaryItem("Register");
    cuwRegister.DuplicateUserNameErrorMessage = umbraco.library.GetDictionaryItem("Duplicated email");
    cuwRegister.DuplicateEmailErrorMessage = umbraco.library.GetDictionaryItem("Duplicated email");
    cuwRegister.InvalidEmailErrorMessage = umbraco.library.GetDictionaryItem("Email address incorrect");
    cuwRegister.InvalidPasswordErrorMessage = umbraco.library.GetDictionaryItem("Password incorrect");
    cuwRegister.EmailRequiredErrorMessage = umbraco.library.GetDictionaryItem("Email required");
    cuwRegister.PasswordRequiredErrorMessage = umbraco.library.GetDictionaryItem("Password required");
    cuwRegister.ConfirmPasswordCompareErrorMessage = umbraco.library.GetDictionaryItem("Password not matching");
    cuwRegister.UserNameRequiredErrorMessage = umbraco.library.GetDictionaryItem("Password not matching");


    Login lwPanelLogin = (Login)lwLogin.FindControl("lwLoginPanel");
    if (lwPanelLogin != null)
    {
        lwPanelLogin.TitleText = umbraco.library.GetDictionaryItem("Already registered? Log in here");
        lwPanelLogin.LoginButtonText = umbraco.library.GetDictionaryItem("Login");
        lwPanelLogin.RememberMeText = umbraco.library.GetDictionaryItem("Remember me next time");
        lwPanelLogin.PasswordLabelText = umbraco.library.GetDictionaryItem("Password");
        lwPanelLogin.UserNameLabelText = "Email";
    }
}

protected void CreateUser(string email, string username, string password)
{
    bool isLoggedIn = System.Web.HttpContext.Current.User.Identity.IsAuthenticated;
    if (Membership.GetUserNameByEmail(email) == null)
    {
        MembershipUser member = Membership.CreateUser("aaa", password, email);
    }

    if(!isLoggedIn)
        if (System.Web.Security.Membership.ValidateUser(username, password))
        {
            FormsAuthentication.SetAuthCookie(username, true);
        }
}

（请注意，我使用用户名字段来获取电子邮件，然后使用电子邮件登录）

Answer 1

您似乎在“OnCreatedUser”方法中设置了用户名。向导试图创建该用户后，将触发此操作。您需要在“OnCreatingUser”方法中设置您的用户名，该方法是事先触发的。

快速取胜，试试这个：

... 
<asp:CreateUserWizard ID="cuwRegister" RequireEmail="false" OnContinueButtonClick="cuwRegister_ContinueButtonClick" OnCreatingUser="cuwRegister_CreatedUser" runat="server">
   <WizardSteps>
...

用户名验证在CreateUserWizard中无效
