ASP.NET成员身份验证电子邮件

Question

尝试根据本文在C＃中创建电子邮件验证。

我创建了一个jangosmtp帐户来发送电子邮件。 但它似乎没有起作用。

Web.config文件：

  <system.net>
    <mailSettings>
      <smtp>
        <network
             host="relay.example.com" port="25" userName="********" password="********" />
      </smtp>
    </mailSettings>
  </system.net>

Registration.aspx

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <asp:CreateUserWizard ID="CreateUserWizard1" runat="server" DisableCreatedUser="True">
        <WizardSteps>
            <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server" />
            <asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server" />
        </WizardSteps>
        <MailDefinition BodyFileName="NewAccountTemplate.htm" From="example@example.com" IsBodyHtml="True"  Subject="Steps to activate your new account..." Priority="High" />
    </asp:CreateUserWizard>
</asp:Content>

Registration.aspx.cs：

namespace WebSite
{
    public partial class Registration : System.Web.UI.Page
    {
        protected void CreateUserWizard1_SendingMail(object sender, MailMessageEventArgs e)
        {
            //Send an email to the address on file
            MembershipUser userInfo = Membership.GetUser(CreateUserWizard1.UserName);

            //Construct the verification URL
            string verifyUrl = Request.Url.GetLeftPart(UriPartial.Authority) + Page.ResolveUrl("~/Verify.aspx?ID=" + userInfo.ProviderUserKey.ToString());

            //Replace <%VerifyUrl%> placeholder with verifyUrl value
            e.Message.Body = e.Message.Body.Replace("<%VerifyUrl%>", verifyUrl);
        }
    }
}

NewAccountTemplate.htm

Verify.aspx.cs：

namespace WebSite
{
    public partial class Verify : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Make sure that a valid query string value was passed through
            if (string.IsNullOrEmpty(Request.QueryString["ID"]) || !Regex.IsMatch(Request.QueryString["ID"], "[0-9a-f]{8}\\-([0-9a-f]{4}\\-){3}[0-9a-f]{12}"))
            {
                InformationLabel.Text = "An invalid ID value was passed in through the querystring.";
            } else {
                //ID exists and is kosher, see if this user is already approved
                //Get the ID sent in the querystring
                Guid userId = new Guid(Request.QueryString["ID"]);

                //Get information about the user
                MembershipUser userInfo = Membership.GetUser(userId);
                if (userInfo == null) {
                    //Could not find user!
                    InformationLabel.Text = "The user account could not be found in the membership database.";
                } else {
                    //User is valid, approve them
                    userInfo.IsApproved = true;
                    Membership.UpdateUser(userInfo);

                    //Display a message
                    InformationLabel.Text = "Your account has been verified and you can now log into the site.";
                }
            }
        }
    }
}

关于我的两件事，即我假设不会导致它起作用。

1. 甚至发送NewAccountTemplate.htm消息怎么知道？ 更新啊，我现在看到createuserwizard1中发生了什么。 仍然收到此错误消息。
2. 在NewAccountTemplate.htm上，我收到一条警告消息：

警告'<％VerifyUrl％>'未找到。

出了什么问题？ 我忽略了什么。

更新2：

如果我添加onsendingmail =“CreateUserWizard1_SendingMail”它会生成一个链接，但是链接不起作用，因为用户永远不会被添加到数据库中我检查了这个。 因此，当我点击电子邮件中的链接时，由于没有具有此ID的用户，因此显示了错误的请求obv。 如果删除该行代码，则会创建用户，但不会生成任何链接：/

Answer 1

我终于开始工作了。

1. onsendingmail =“CreateUserWizard1_SendingMail”这应该在创建用户向导中。

    <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server" onsendingmail="CreateUserWizard1_SendingMail"> <asp:CreateUserWizard ID="CreateUserWizard1" runat="server" DisableCreatedUser="True"> <WizardSteps> <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server" /> <asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server" /> </WizardSteps> <MailDefinition BodyFileName="NewAccountTemplate.htm" From="example@example.com" IsBodyHtml="True" Subject="Steps to activate your new account..." Priority="High" /> </asp:CreateUserWizard> 

2. 在NewAccountTemplate.htm中仅使用<％VerificationUrl％>

3. 将registration.aspx.cs更改为

    // Get the UserId of the just-added user MembershipUser newUser = Membership.GetUser(CreateUserWizard1.UserName); Guid newUserId = (Guid)newUser.ProviderUserKey; // Determine the full verification URL (ie, http://yoursite.com/Verification.aspx?ID=...) string urlBase = Request.Url.GetLeftPart(UriPartial.Authority) + Request.ApplicationPath; string verifyUrl = "Verify.aspx?ID=" + newUserId.ToString(); string fullUrl = urlBase + verifyUrl; // Replace <%VerificationUrl%> with the appropriate URL and querystring e.Message.Body = e.Message.Body.Replace("<%VerificationUrl%>", fullUrl);
