如何使用当前用户登录?当前用户将显示在默认主页的母版页中,母版页中的标签将继承到母版页的内容页面。
这是我的登录页面asp代码:
<div class="container-fluid">
<form class="form-signin" runat="server">
<h1 class="form-signin-heading text-muted">Sign In</h1>
<asp:TextBox ID ="email" runat="server" CssClass="form-control" placeholder="Email Address"></asp:TextBox>
<asp:TextBox ID ="password" runat="server" CssClass="form-control" placeholder="Password" TextMode="Password"></asp:TextBox>
<br />
<asp:Button ID="btnLogIN" runat="server" CssClass="btn btn-primary btn-block" Text="Log In" OnClick="btnLogIN_Click" />
</form>
我的aspx.cs代码在这里,我不知道这是否正确。
protected void btnLogIN_Click(object sender, EventArgs e)
{
Utility u = new Utility();
string conn = u.connect();
SqlConnection connUser = new SqlConnection(conn);
SqlCommand read = connUser.CreateCommand();
SqlDataReader reader = null;
int empid = 0;
string dbuser = "";
string dbpword = "";
string username = email.Text;
string passwords = password.Text;
string login = "Select * from MOSEFAccount where UserName = '" + username + "' AND Password = '" + passwords + "'";
try
{
connUser.Open();
read.CommandText = login;
reader = read.ExecuteReader();
}
catch
{
Console.WriteLine("Error");
}
while (reader.Read())
{
empid = reader.GetInt32(0);
dbuser = reader.GetString(1);
dbpword = reader.GetString(2);
}
if (username == dbuser && passwords == dbpword)
{
Response.Redirect("~/Default.aspx?ID=" + empid);
}
else
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append(@"<script type ='text/javascript'>");
sb.Append("alert('Invalid Account');");
sb.Append(@"</script>");
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "EditHideModalScript", sb.ToString(), false);
}
connUser.Close();
}
答案 0 :(得分:0)
您能详细说明当前用户的含义吗?除非您登录,否则您不是登录用户而是匿名用户。
将提取的数据存储在Session对象中,并随时随地访问它。例如: 有关存储详细信息,请使用: -
if (username == dbuser && passwords == dbpword)
{
Session["UserName"] = username;
Session["EmpId"] = empid;
Response.Redirect("~/Default.aspx?ID=" + empid);
}
用于显示用途(在母版页中):
<%=Session["UserName"]%>
<%=Session["EmpId"]%>
您可以在此基础上构建一个User类,然后创建此类的实例并将实例本身存储在Session中。
