Static ClearTime As Date If UserTable Is Nothing Then \'创建用于记录登录信息的临时表 ClearTime = Date.Now() Dim dtb As New DataTableBuilder("UserInfos") dtb.AddDef("UserName", Gettype(String), 90) dtb.AddDef("UserID",Gettype(String),16) dtb.AddDef("ActiveTime",Gettype(Date)) UserTable = dtb.Build(True) \'true代表使用完自动销毁表且不显示表 End If If (Date.Now - ClearTime).TotalMinutes >= 30 Then \'清除超过30分钟没有操作的登录信息 UserTable.DeleteFor("ActiveTime < #" & Date.Now.AddMinutes(-30) & "#") ClearTime = Date.Now() End If Dim wb As New weui \'身份验证 Dim UserName As String Dim Password As String Dim UserID As String If e.Path = "logon.htm" \'验证用户名和密码 If e.PostValues.ContainsKey("username") AndAlso e.PostValues.ContainsKey("password") Then Dim Verified As Boolean \'用于标记用户是否通过了身份验证 UserName = e.PostValues("username") Password = e.PostValues("password") Dim dr1 As DataRow = DataTables("Table_User").SQLFind("UseName=\'" & EncryptText(UserName,"1","123") & "\'") If dr1 IsNot Nothing Then If dr1("UserPWd") = EncryptText(Password ,"1","123") Then Verified = True End If End If If Verified Then UserID = Rand.NextString(16) \'生成随机用户ID UserName = EncryptText(UserName,"whblq","whblq") \'将用户名加密. Dim dr As DataRow = UserTable.Find("UserName = \'" & UserName & "\'") If dr IsNot Nothing Then \'如果是重复登录,删除以前的登录信息 dr.Delete() End If dr = UserTable.AddNew() dr("UserName") = UserName dr("UserID") = UserId dr("ActiveTime") = Date.Now \'记录登录时间 wb.AppendCookie("username",UserName) \'将用户名和密码写入cookie wb.AppendCookie("userid",UserID) wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'直接跳转到首页 e.WriteString(wb.Build) \'生成网页 Return \'必须的 End If End If Else \'其它页面从Cookie提取登录信息进行验证 UserName = e.Cookies("username") \'从cookie中获取用户名 UserID = e.Cookies("userid") \'从cookie中获取 随机ID Dim dr As DataRow = UserTable.Find("UserName = \'" & UserName & "\'") If dr IsNot Nothing AndAlso dr("UserID") = UserID Then \'如果通过验证,更新活动时候,继续访问其它页面. dr("ActiveTime") = Date.Now \'更新活动时间 Else \'如果验证失败 wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'那么直接跳转到登录页面 e.WriteString(wb.Build) \'生成网页 Return \'必须的 End If End If \'开始生成网页 Select Case e.path Case "logon.htm" \'登录页面 wb.AddPageTitle("","pageheader","个人应用系统","--夜 语--") \'wb.AddPageFooter("","pf1","Copyright © 2008-2016 foxtable.com").AddLink("底部链接","http://www.foxtable.com") wb.AddPageFooter("","pf1","京") If e.PostValues.ContainsKey("username") AndAlso e.PostValues.ContainsKey("password") Then \'判断是否是验证失败后的重新登录 wb.AddTopTips("","toptip1","用户名或密码错误!").msec = 2000 \'如果用户通过登录按钮访问,则给用户一个2秒的提示. End If wb.AddForm("","form1","logon.htm") With wb.AddInputGroup("form1","ipg1") .AddInput("username","户名:","text") .AddInput("password","密码:","password") End With With wb.AddButtonGroup("form1","btg1",True) .Add("btn1", "登录", "submit") End With Case "exit.htm" \'退出登录 wb.DeleteCookie("username") \'清除cookie中原来的用户名和密码 wb.DeleteCookie("password") wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'然后直接跳转到登录页面 Case "", "default.htm" \'首页 wb.AddPageTitle("","pageheader","个人系统") wb.AddPageFooter("","pf1","号-1") With wb.AddGrid("","g1") .Add("c1","增加订单", "./images/button.png").Attribute = "" .Add("c12","退出", "./images/exit.png", "exit.htm") \'退出登录 End With End Select e.WriteString(wb.Build) |
