asp.net连接LDAP数据,并从LDAP中取出相关数据(1)
ASP.NET连接LDAP数据库的有关信息
一、封装在DAL层中的获取用户信息的函数
/// <summary>
/// 按照用户Id查找用户信息
/// </summary>
/// <param name="userId"></param>
/// <returns></returns>
publicDirectoryEntry GetUser(string username)
{
string path = System.Configuration.ConfigurationManager.ConnectionStrings["path"].ConnectionString;
string pname = System.Configuration.ConfigurationManager.ConnectionStrings["pname"].ConnectionString;
string pwd = System.Configuration.ConfigurationManager.ConnectionStrings["pwd"].ConnectionString;
// 3个连接数据库的信息写在配置文件里
DirectoryEntry deuser; //定义变量
try
{
DirectoryEntry de = newDirectoryEntry (path, pname, pwd, AuthenticationTypes.Secure);
DirectorySearcher deSearch = newDirectorySearcher(de); //连接LDAP数据库
deSearch.Filter = "(&(objectClass=userinfo)(LOGINNAME=" + username + "))"; //筛选比对
//上面这句话修改为:mySearcher.Filter = "(&(objectClass=userinfo)(&(LOGINNAME=" + txtUserId.Text + ")(LOGINPASSWORD=" + txtUserPwd.Text + ")))";//作为登录是用户帐号和密码认证
deSearch.SearchScope = SearchScope.Subtree;
SearchResult result = deSearch.FindOne(); //筛选比对得出一个结果,存储在result中
if (result != null)
{
deuser = result.GetDirectoryEntry(); //得到筛选结果,并赋值给deuser中
return deuser;
}
else
{
returnnull;
}
}
catch(Exception ex)
{
// LogManage.SaveInfo(ex.ToString());
returnnull;
}
二、配置文件信息
<connectionStrings>
<add name="path"
connectionString="LDAP://192.168.1.1/OU=123,DC=123,DC=COM" />
<add name="pname"
connectionString="123" />
<add name="pwd"
connectionString="123" />
</connectionStrings>
三、实现层
1、页面信息
用户id:(textbox框)
用户名称:(textbox框)
用户密码:(textbox框)
电子邮箱:(textbox框)
ButtonID="butquchu"(读取数据按钮)
2、事件函数代码
protectedvoid butquchu_Click(object sender, EventArgs e)
{
ldapDAO ld= newldapDAO ();
string username = Session["LOGINNAME"].ToString(); //根据上一页的登录信息获取用户帐号,存储在session中。
labname.Text = username;
DirectoryEntry de = ld.GetUser(username); //调用ldapDAO中的获取用户信息函数
if (de != null)
{
if (de != null)
{
if (de.Properties["USERID"].Value != null)
{
txtuserid.Text = de.Properties["USERID"].Value.ToString();
}
if (de.Properties["LOGINNAME"].Value != null)
{
txtusername.Text = de.Properties["LOGINNAME"].Value.ToString();
}
if (de.Properties["LOGINPASSWORD"].Value != null)
{
txtpwd.Text = de.Properties["LOGINPASSWORD"].Value.ToString();
}
if (de.Properties["EMAIL"].Value != null)
{
txtmail.Text = de.Properties["EMAIL"].Value.ToString();
}
}
