c# - 忘记密码网址

Question

我有一个使用 asp.net 登录控件的 Web 应用程序。此外，我还使用了密码恢复控件，供用户恢复密码。一旦用户在恢复控件中完成输入他们的详细信息，包含验证 URL 的电子邮件将发送到用户的电子邮件地址。单击 URL 后，它将引导用户进入我的 Web 应用程序的 UserProfile，在该应用程序中，它允许用户更改其密码。

现在的问题是，因为我为 UserProfile.aspx 设置了一个访问规则以拒绝匿名用户，当我从 URL 重定向到 UserProfile.aspx 页面时，它反而将我定向到登录页面(系统将我识别为匿名用户)。

为什么会这样？单击 URL(包括所有用户信息)后，是否有任何地方可以直接进入用户配置文件页面？

URL 看起来像这样:

http://localhost:1039/Members/UserProfile.aspx?ID=56f74cc7-7680-4f1b-9207-0ab8dad63cad 

URL 的最后一部分实际上是 userId。

这是用户配置文件 aspx 的代码:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
              ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" 
              SelectCommand="SELECT aspnet_Membership.Email, Details.CustName, Details.CustNum, Details.CustRole, Details.CustStatus, Details.PName, Details.PEmail, Details.PRole, Details.WedDate, aspnet_Users.UserName, Details.UserId FROM Details INNER JOIN aspnet_Membership ON Details.UserId = aspnet_Membership.UserId INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE (Details.UserId = @UserId)" 


              UpdateCommand="update Details SET CustName = @CustName, CustNum = @CustNum, CustRole = @CustRole, CustStatus = @CustStatus, PName = @PName, PEmail = @PEmail, PRole = @PRole, WedDate = @WedDate WHERE [UserId] = @UserId

                            Update aspnet_Membership Set Email= @email WHERE [UserId] = @UserId"

              DeleteCommand= "DELETE FROM Details WHERE UserId = @UserId;"> 

              <DeleteParameters>
                  <asp:ControlParameter ControlID="lblHidden" Name="UserId" PropertyName="Text" 
                      Type="String" />
              </DeleteParameters>

              <SelectParameters>
                  <asp:ControlParameter ControlID="lblHidden" Name="UserId" PropertyName="Text" />

              </SelectParameters>

              <UpdateParameters>
                  <asp:Parameter Name="CustName" />
                  <asp:Parameter Name="CustNum" />
                  <asp:Parameter Name="CustRole" />
                  <asp:Parameter Name="CustStatus" />
                  <asp:Parameter Name="PName" />
                  <asp:Parameter Name="PEmail" />
                  <asp:Parameter Name="PRole" />
                  <asp:Parameter Name="WedDate" />
                  <asp:Parameter Name="UserId" />
                  <asp:Parameter Name="email" />
              </UpdateParameters>


          </asp:SqlDataSource>
          <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" 
              DataSourceID="SqlDataSource1" Height="50px" Width="125px">
              <Fields>
                  <asp:BoundField DataField="Email" HeaderText="Email" SortExpression="Email" />
                  <asp:BoundField DataField="CustName" HeaderText="CustName" 
                      SortExpression="CustName" />
                  <asp:BoundField DataField="CustNum" HeaderText="CustNum"

                  <asp:BoundField DataField="CustRole" HeaderText="CustRole" 
                      SortExpression="CustRole" />
                  <asp:BoundField DataField="CustStatus" HeaderText="CustStatus" 
                      SortExpression="CustStatus" />
                  <asp:BoundField DataField="PName" HeaderText="PName" SortExpression="PName" />
                  <asp:BoundField DataField="PEmail" HeaderText="PEmail" 
                      SortExpression="PEmail" />
                  <asp:BoundField DataField="PRole" HeaderText="PRole" SortExpression="PRole" />
                  <asp:BoundField DataField="WedDate" HeaderText="WedDate" 
                      SortExpression="WedDate" />
                  <asp:BoundField DataField="UserName" HeaderText="UserName" 
                      SortExpression="UserName" />
                  <asp:BoundField DataField="UserId" HeaderText="UserId" 
                      SortExpression="UserId" />
                  <asp:CommandField ShowEditButton="True" />
              </Fields>
          </asp:DetailsView>
          <asp:Label ID="lblHidden" runat="server" Text="Label" Visible="False"></asp:Label>



          <asp:Button ID="btnDelete" runat="server" onclick="btnDelete_Click" 
              Text="Delete" />

下面是代码:

protected void Page_Load(object sender, EventArgs e)
    {
         MembershipUser currentUser = Membership.GetUser();
        lblHidden.Text = currentUser.ProviderUserKey.ToString();
    }

    protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
    {
        // Get a reference to the currently logged on user
        MembershipUser currentUser = Membership.GetUser();

        // Determine the currently logged on user's UserId value
        // Assign the currently logged on user's UserId to the @UserId parameter
        //access the parameter value using e.Command.Parameters 
        //programmatically set the @UserId:
        e.Command.Parameters["@UserId"].Value = currentUser.ProviderUserKey.ToString();



    }
    protected void btnDelete_Click(object sender, EventArgs e)
    {

        SqlConnection connection = new SqlConnection();
        connection.ConnectionString = ConfigurationManager.ConnectionStrings["ASPNETDBConnectionString1"].ConnectionString;
        SqlCommand cmd = new SqlCommand();
        SqlCommand cmd1 = new SqlCommand(); 
        string userId = lblHidden.Text;

        cmd.Connection = connection;
        cmd.CommandText = "DELETE FROM Details WHERE UserId ='" + userId + "'";


        cmd1.Connection = connection;
        cmd1.CommandText = "DELETE FROM aspnet_Membership WHERE UserId ='" + userId + "'"; 

        connection.Open();

        cmd.ExecuteNonQuery();
        cmd1.ExecuteNonQuery();


        connection.Close();


      Response.Redirect("Home.aspx");
    }

其次，有什么方法可以为 URL 设置过期时间吗？如果 URL 被第二次点击，它不会将用户重定向到任何地方。我看到很多帖子，其中大多数建议在数据库中添加一列。有没有其他方法可以在不接触数据库的情况下设置到期时间？？？

Answer 1

考虑为更改密码链接创建一个单独的页面。让此页面采用唯一标识符。这个标识符应该只工作一次，有一个到期日期，并且特定于该用户。公开此页面:

<location path="changepassword.aspx">
 <system.web>
   <authorization>
     <allow users="*"/>
   </authorization>
 </system.web>
</location>

您需要在某处针对用户存储唯一标识符。如果你不想影响你当前的模式，你可以创建一个新表:

PK | Identifier | UserID                               | expires
1  | abcd       | ffffffff-ffff-ffff-ffff-ffffffffffff | 16-jul-2012 18:26

请求页面时，如果标识符已过期，则不允许页面运行。更改密码后，使标识符无效 - 删除它，或将到期日期设置为过去的日期(例如现在)。
