本文小编为大家详细介绍“C#怎么实现密码验证与输错密码账户锁定”,内容详细,步骤清晰,细节处理妥当,希望这篇“C#怎么实现密码验证与输错密码账户锁定”文章能帮助大家解决疑惑,下面跟着小编的思路慢慢深入,一起来学习新知识吧。

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;
        }
