Asp.net用户管理API的应用（上）(图)
ASP.NET官方标准控件实现用户的管理，虽然简单，但控件封装型很强，开发人员不能明白做了什么样的调用，还有另一方面，标准控件的使用，很大程度上限制了程序的可变性。如果自开发一套用户管理系统，可行，但又失去了标准控件的作用，于是用API来管理用户，成为一个很好的选择，下面列出主要的用户管理APS实例：
1.注册用户
用Membership.CreateUser来创建新用户，注意密码要包含一个符号，Membership位于System.Web.Security命名空间内。
cs代码
1try
2 {
3 MembershipCreateStatus MCS;
4 Membership.CreateUser(name.Text, password.Text,email .Text ,question .Text,answer .Text ,true , out MCS );
5 Response.Write(MCS.ToString ());
6 }
7 catch(Exception s)
8 {
9 //异常处理代码
10 }
aspx代码
1 <asp:Label ID="Label1" runat="server" Text="用户名："></asp:Label>
2 <asp:TextBox ID="name" runat="server" Width="196px"></asp:TextBox>
3 <asp:Label ID="Label2" runat="server" Text="密码："></asp:Label>
4 <asp:TextBox ID="password" runat="server" Width="197px"></asp:TextBox>
5 <asp:Label ID="Label3" runat="server" Text="确认密码："></asp:Label>
6 <asp:TextBox ID="OtherPass" runat="server" Width="196px"></asp:TextBox>
7 <asp:Label ID="Label4" runat="server" Text="电子邮件："></asp:Label>
8 <asp:TextBox ID="email" runat="server" Width="193px"></asp:TextBox>
9 <asp:Label ID="Label5" runat="server" Text="安全提示问题："></asp:Label>
10 <asp:TextBox ID="question" runat="server" Width="189px"></asp:TextBox>
11 <asp:Label ID="Label6" runat="server" Text="安全答案："></asp:Label>
12 <asp:TextBox ID="answer" runat="server" Width="187px"></asp:TextBox>
13 <asp:Button ID="Button1" runat="server" Text="注册" Width="69px" />
2.用户登录
用户登录用Membership.ValidateUser来验证用户名和密码。如果通过验证，调用FormsAuthentication.RedirectFromLoginPage导向目标页面（这里以及后面的一些设置都是配合Forms验证展开，都预先在Web.config中配置好Forms的验证策略）。
cs代码
1if (Membership.ValidateUser(UserName.Text,Password.Text))
2 {
3 FormsAuthentication.RedirectFromLoginPag(UserName.Text, false);
4 }
5 else
6 {
7 Response.Write("登录失败！");
8 }
aspx代码
1 <asp:Label ID="Label1" runat="server" Text="用户名："></asp:Label>
2 <asp:TextBox ID="UserNmae" runat="server"></asp:TextBox>
3 <asp:Label ID="Label2" runat="server" Text="密码："></asp:Label>
4 <asp:TextBox ID="Password" runat="server"></asp:TextBox>
5 <asp:Button ID="Login_But" runat="server" Text="登录" Width="69px" />
7 <asp:HyperLink ID="FindPass_HL" runat="server" NavigateUrl="~/FindPassword.aspx">忘记密码</asp:HyperLink>
8 <asp:HyperLink ID="Reg_HL" runat="server" NavigateUrl="~/register.aspx">注册</asp:HyperLink>
3.找回密码
CS中的邮件发送方法，关于一些邮件的配置是在web.config中存放，方法中有相关的获取方法
cs代码
1using System;
2using System.Collections;
3using System.Configuration;
4using System.Data;
5using System.Web;
6using System.Web.Security;
7using System.Web.UI;
8using System.Web.UI.HtmlControls;
9using System.Web.UI.WebControls;
10using System.Web.UI.WebControls.WebParts;
11using System.Web.Configuration;
12using System.Net.Configuration;
13using System.Net.Mail ;
14public partial class FindPassword : System.Web.UI.Page
15{
16 protected void Page_Load(object sender, EventArgs e)
17 {
18 if (!IsPostBack)
19 {
20 Wizard1.ActiveStepIndex = 0;
21 }
22 }
23 protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e)
24 {
25 try
26 {
27 Label1.Text = "问题是：" + Membership.GetUser(Quest_TB.Text).PasswordQuestion;
28 }
29 catch (Exception ee)
30 {
31 Response.Write("异常,详细错误："+ee.Message);
32 }
33 }
34 protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e)
35 {
36 try
37 {
38 Configuration c = WebConfigurationManager.OpenWebConfiguration(@"~\web.config"); ;
39 NetSectionGroup ns = NetSectionGroup.GetSectionGroup(c);
40 string forms = ns.MailSettings.Smtp.From;
41 string hosts = ns.MailSettings.Smtp.Network.Host;
42 int ports = ns.MailSettings.Smtp.Network.Port;
43 string usernames = ns.MailSettings.Smtp.Network.UserName;
44 string passwords = ns.MailSettings.Smtp.Network.Password;
45 MailAddress from = new MailAddress(forms);
46 MailAddress to = new MailAddress(Membership.GetUser(TextBox1.Text).Email);
47 MailMessage message = new MailMessage(from, to);
48 message.Subject = "密码";
49 string nr = "您好：你的密码为：" + Membership.GetUser(Quest_TB.Text).ResetPassword(Answer_TB.Text);
50 message.Body = nr;
51 SmtpClient client = new SmtpClient(hosts, ports);
52 client.Send(message);
53 }
54 catch (Exception ee)
55 {
56 Response.Write("发送邮箱密码错误！详细信息："+ee.Message);
57 }
58 }
59}
