C#实现密码验证与输错密码账户锁定
时间：2022-09-26 09:35:56|栏目：.NET代码|点击： 次
C#实现的Check Password，并根据输错密码的次数分情况锁定账户：如果输入错误3次，登录账户锁定5分钟并提示X点X分后重试登录。如果5分钟后再次输入，累计输入错误密码累计达到5次。则账户会被永久锁定，需联系系统管理员进行把数据库中的输入错误的次数（errorcount）进行清零解锁才能登陆。实现代码如下：
public class UserInfo1
{
public string Error_count { get; set; }
public string Error_time { get; set; }
}
public ExecutionResult CheckAccountPwd(string account, string password)
{
ExecutionResult execRes;
execRes = new ExecutionResult();
string[] strs = account.Split(new string[] { "\\" }, StringSplitOptions.RemoveEmptyEntries);
if (strs.Length < 2)
{
execRes.Status = false;
execRes.Message = "无效的账号。";
}
else
{
UserInfo1 info1 = null;
execRes = CallEEPMethod.Execute(dbName, "sDEM2131", "GetUserInfo", strs[1].ToLower());
if (execRes.Status && execRes.Anything != null)
{
info1 = JsonConvert.DeserializeObject<UserInfo1>(execRes.Anything.ToString());
if (info1 != null)
{
int errcount = Convert.ToInt32(info1.Error_count);
DateTime errtime = Convert.ToDateTime(info1.Error_time);
if (errcount != 5)
{
//int errorCount
DateTime dt0 = DateTime.Now;
DateTime dt1 = errtime.AddMinutes(5);
double s = (dt1 - dt0).TotalSeconds;
if (errcount == 3 && s > 0)
{
execRes.Status = false;
execRes.Message = "密码连续输入错误3次，请于 " + errtime.AddMinutes(+5).ToString("yyyy-MM-dd HH:mm:ss") + " 之后重试，thanks!";
}
else
{
if (CheckFromLDAP(strs[1], password, strs[0]))
{
CPU.Models.UserInfo userInfo = CheckUser(strs[1]);
if (userInfo == null)
{
execRes.Status = false;
execRes.Message = "您没有权限操作此系统！";
}
else
{
execRes.Status = true;
execRes.Anything = userInfo;
//error count 清0
CallEEPMethod.Execute(dbName, "sDEM2131", "UpdateUserLoginError", strs[1].ToLower() + ","+"0" + "," + DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));
}
}
else
{
execRes.Status = false;
// 次数+1
if (errcount + 1 > 1)
execRes.Message = "密码连续输入错误" + (errcount+1).ToString() + "次。密码连续输错5次将锁定！";
else
execRes.Message = "密码输入错误!";
dt0 = DateTime.Now;
CallEEPMethod.Execute(dbName, "sDEM2131", "UpdateUserLoginError", strs[1].ToLower() + "," + (errcount + 1).ToString()+"," + DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));
if (errcount + 1 == 3)
execRes.Message = "密码连续输入错误" + (errcount + 1).ToString() + "次，请于 " + dt0.AddMinutes(5).ToString("yyyy-MM-dd HH:mm:ss") + " 之后重试，thanks!";
if (errcount + 1 == 5)
execRes.Message = "账号密码连续输入错误5次，已锁定!请联系管理员解锁，thanks!";
}
}
}
else
{
execRes.Status = false;
execRes.Message = "账号密码连续输入错误5次，已锁定!请联系管理员解锁，thanks!";
}
}
else
{
execRes.Status = false;
execRes.Message = "找不到此账号，请重新输入!";
}
}
else
{
execRes.Status = false;
execRes.Message = "找不到此账号，请重新输入!";
}
}
return execRes;
}
根据登录不同的网域进行Form验证
private bool CheckFromLDAP(string ntID, string ntPWD, string domain)//根据登录的不同网域进行Form验证
{
bool result = false;
string strUser;
try
{
strUser = domain + "\\" + ntID;
if (domain.ToLower().Equals("gi"))
domain = "gi.compal.com";
else if (domain.ToLower().Equals("cqc_cci"))
domain = "10.140.1.1";
else if (domain.ToLower().Equals("vn"))
domain = "10.144.2.101";
else if (domain.ToLower().Equals("njp_cci"))
domain = "10.128.50.1";
else
domain = "compal.com";
DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, strUser, ntPWD);
using (DirectorySearcher searcher = new DirectorySearcher(entry))
{
searcher.Filter = string.Format("(&(objectClass=user)(sAMAccountName={0}))", ntID);
SearchResult sr = searcher.FindOne();
using (SearchResultCollection results = searcher.FindAll())
{
if (results.Count > 0)
{
//if (results[0].Properties.Contains("employeeID"))
// empID = results[0].Properties["employeeID"][0].ToString();
//else
// empID = results[0].Properties["extensionattribute3"][0].ToString();
result = true;
}
}
}
}
catch (Exception ex)
{
//LogHelper.Error(ex.Message);
}
return result;
}
根据不同的用户登录进行权限管理
public bool CheckPermission(string controllerName, string actionName,string plant, string userID)
{
bool result = false;
//if (actionName.StartsWith("_"))
// actionName = actionName.Substring(1);
UserInfo userInfo = CheckUser(userID);
if (userInfo!=null)
{
if (controllerName == "Home")
result = true;
else if (userInfo.Permissions.Contains(controllerName))
{
if (!string.IsNullOrEmpty(plant))
{
if (userInfo.PlantCode.ToLower() == plant.ToLower() || userInfo.PlantCode == "ALL")
result = true;
}
else
result = true;
}
}
return result;
}
