在petshop3.0中有一个MyAccount.aspx页面,此页面对用户不同的操作做出不同的提示,比如新创建用户,用户更新,用户登录.其中有三个参数
private const string ACTION_CREATE = "create";
private const string ACTION_UPDATE = "update";
private const string ACTION_SIGN_IN = "signIn";
private const string TITLE_CREATE = "Create Account";
private const string TITLE_UPDATE = "Edit Account";
private const string TITLE_SIGN_IN = "Sign In";
private const string MSG_CREATE = "Your account was successfully created.";
private const string MSG_UPDATE = "Your account was successfully updated.";
private const string MSG_SIGN_IN = "Welcome to the .NET Pet Shop Demo.";通过检测Request["action"]来传递,然后做出判断,显示不同提示信息
override protected void OnLoad(EventArgs e)
{
string pageAction = WebComponents.CleanString.InputText(Request["action"], 20);
switch(pageAction)
{
case ACTION_CREATE:
lblMessage.Text = MSG_CREATE;
break;
case ACTION_UPDATE:
lblMessage.Text = MSG_UPDATE;
break;
case ACTION_SIGN_IN:
lblMessage.Text = MSG_SIGN_IN;
break;
}
}
在 WEB项目中的ProcessFlow文件夹中有个AccountController.cs帐户管理类.它引用了已经封装好了的Account类中的方法.然后
这个类根据用户不同的操作进行导向,并赋予权限
1/**//// <summary>
2 /// 控制帐户相关操作的流程
3 /// </summary>
4 public class AccountController {
5 // 导航内容
6
7 private const string ACCOUNT_KEY = "ACCOUNT_KEY";
8 private const string URL_DEFAULT = "default.aspx";
9 private const string URL_SIGNIN = "SignIn.aspx";
10 private const string URL_ACCOUNTCREATE = "MyAccount.aspx?action=create";
11 private const string URL_ACCOUNTSIGNIN = "MyAccount.aspx?action=signIn";
12 private const string URL_ACCOUNTUPDATE = "MyAccount.aspx?action=update";

27 public bool ProcessLogin(string userId, string password){
28
29 // 使用帐户业务逻辑层来登录
30 Account account = new Account();
31 AccountInfo myAccountInfo = account.SignIn(userId, password);
32
33 //登录成功，在Session中存储状态并且跳转
34 if (myAccountInfo != null) {
35 HttpContext.Current.Session[ACCOUNT_KEY] = myAccountInfo;
36
37 // 决定用户跳转到哪儿
38 // 返回到登录成功的提示页面
39 if (FormsAuthentication.GetRedirectUrl(userId, false).EndsWith(URL_DEFAULT)) {
40
41 FormsAuthentication.SetAuthCookie(userId, false);
42 HttpContext.Current.Response.Redirect(URL_ACCOUNTSIGNIN, true);
43
44 }else{

64
65 // 调用Insert方法
66 account.Insert(newAccountInfo);
67
68 // 在Session中存储帐户信息，在cookie中存储验证信息
69 HttpContext.Current.Session[ACCOUNT_KEY] = newAccountInfo;
70 FormsAuthentication.SetAuthCookie(newAccountInfo.UserId, false);
71
72 //跳转到注册成功页面
73 HttpContext.Current.Response.Redirect(URL_ACCOUNTCREATE, true);

76 }catch {
77 return false;

114 HttpContext.Current.Response.Redirect(URL_SIGNIN, true);
115
116 }
117 return null;
118 }else{

120 }
121 }
122
123 /**//// <summary>

131
132 if (myAccount != null && myAccount.IsShowFavorites) {
133 return myAccount.Category;
134 }else{

147 // 清除session内容
148 HttpContext.Current.Session.Clear();
149 // 取消当前会话
150 HttpContext.Current.Session.Abandon();
151 }
152 }接着看另外三个页面,登录页面,创建帐户页面,修改帐户信息页面
登录页面很简单,引用了刚才的帐户管理类
ProcessFlow.AccountController accountController = new ProcessFlow.AccountController();
if (!accountController.ProcessLogin(userId, password)){
// If we fail to login let the user know
valUserId.ErrorMessage = MSG_FAILURE;
valUserId.IsValid = false;
}
创建帐户页面和修改帐户信息页面比较相似,修改帐户信息页面无法修改密码.
当创建帐户页面时需要同时向三张表插入数据,分别是用户基本信息表,用户登录表,用户配置表
修改信息页面只需要修改两张表, 用户基本信息表和用户配置表,因为用户无法更改用户名和密码,所以用户登录表无须改变.
其中注册页面的地址栏和信息配置选项是用用户控件来完成的
当然最后还有注销页面
override protected void OnLoad(EventArgs e) {
// Create an instance of the account controller
ProcessFlow.AccountController accountController = new ProcessFlow.AccountController();
// Tell the controller that the user is logging out
accountController.LogOut();
}
