尝试在基于 this article的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);
        }
    }
}

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.

>如何知道甚至发送NewAccountTemplate.htm消息？更新啊,我现在看到createuserwizard1中发生了什么.仍然收到此错误消息.
>在NewAccountTemplate.htm上,我收到一条警告消息：

Warning ‘<% VerifyUrl %>’ was not found.

出了什么问题？我忽略了什么.

更新2：

如果我添加onsendingmail =“CreateUserWizard1_SendingMail”它生成一个链接,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：/

解决方法

我终于开始工作了.

> 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>

>仅使用<％VerificationUrl％>在NewAccountTemplate.htm中
>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 (i.e.,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);
