想要对多用户进行身份验证，并且拒绝任何用户进入网站，而无需通过抛出登录页面 [英] iwant to do authencation for multi user and deny any user to enter to site whithout pass throw log in page

问题描述

我想对多用户进行身份验证，并拒绝任何用户进入该页面，而无需通过登录页面
为可能的站点添加安全性，并拒绝任何用户传递到没有传递登录页面的站点页面] \
answe非常漂亮，我有很多现成的代码


但是我想从您的代码中获取密码，如果我们拒绝用户，则无人可以输入我想创建新用户

并输入姓名，并将用户名存储在数据库中

和
我会但可能会编码


SqlConnection c;
SqlCommand m;
SqlDataReader r;

公共无效get_con()
{
c =新的SqlConnection();
c.ConnectionString = @数据源=.\ SQLEXPRESS; AttachDbFilename = | DataDirectory | \ pard.mdf;集成安全性= True;用户实例= True";
}

受保护的void Page_Load(对象发送者，EventArgs e)
{
get_con();
}


受保护的void Button1_Click(对象发送者，EventArgs e)
{


m =新的SqlCommand();
c.Open();
m.Connection = c;

m.Parameters.Add("@ a"，TextBox2name.Text);
m.CommandText =从[用户]中选择[prd]，其中nam = @ a";


r = m.ExecuteReader();
如果(r.HasRows == false)
Response.Write("rrrrr");
如果(r.Read())
{
如果(r ["prd"].ToString()== TextBox1pard.Text.Trim())
{
Response.Redirect("WebForm6.aspx");
}

}
其他
{
Response.Write("wrong prd");
}
c.Close();




}

推荐答案

一起看看ASP.Net授权和.Net表单身份验证

http://msdn.microsoft.com/en-us/library/wce3kxhd.aspx [ ^ ]

http://msdn.microsoft.com/en-us/library/ff647070.aspx [ ^ ]

通过将两者结合起来，可以强制所有未经授权的用户必须登录.

例如，在您的Web配置中...

Have a look at ASP.Net Authorisation along with .Net forms authentication

http://msdn.microsoft.com/en-us/library/wce3kxhd.aspx[^]

http://msdn.microsoft.com/en-us/library/ff647070.aspx[^]

By combining the two, you can force all unauthorised users to have to login.

E.g in your web config...

<authentication mode="Forms">
  <forms name="yourApplicationName"

         loginUrl="~/LogOn.aspx"

         path="/"

         protection="All"

         timeout="5"

         slidingExpiration="true"

         defaultUrl="~/Home.aspx"

         requireSSL="false"

         enableCrossAppRedirects="false"

         cookieless="UseCookies"/>
</authentication>
<authorization>
  <deny users="?"/>
</authorization>

拒绝用户?元素将阻止所有未经授权的用户访问网页，他们将必须首先登录

The deny users ? element will stop all unauthorised users from accessing web pages, they will have to sign on first
