我要评论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;
}
