上篇我们说到了如何实现登陆,但是腾讯对某一个IP在某一段时间的登陆行为存在检测,对于存在异常的IP会出现验证码
但是腾讯的验证码比较难识别,或许是我对图形识别(匹配)的技术还认识的不够深刻
噪线,倾斜,字符连接,镂空,噪线字符同色.这些都是识别的难点,具体的算法我试过,识别成功率很低,技术不够没办法,好了偏题了,还是说ADSL拨号的实现
ADSL拨号需要调用windows api来实现
调用RASAPI32.DLL
ADSL的所有操作都要调用这个dll,详细的调用方法和参数,大家可以查询MSDN
不过对于我这种懒人,明白了原理,能使用拿来主义就拿哦
在codeplex上有个叫dotras的项目这个项目封装了rasapi dll的操作,大家可以下载下来使用,不用自己在封装了,关于操作方法可以参见实例,下载过来后有示例的
ListhistoryIps = new List ();
private void ChangeIP()
{ SysConfig.IsChangeIp = true;
QQHelper.WriteLog("更换IP"); HANDUPCON:
string oldIpAddress = "";
RasConnection oldConn = null;
GetIPAddress(out oldIpAddress, out oldConn);
string entryName = "";
if (oldConn != null)
{ entryName = oldConn.EntryName;
RasIPInfo ipAddresses = (RasIPInfo)oldConn.GetProjectionInfo(RasProjectionType.IP);
string oldIp = ipAddresses.IPAddress.ToString();
ipAddresses = null;
QQHelper.WriteLog("现在的IP是" + oldIp); bool isUp = false;
try
{ Console.WriteLine("开始挂断"); oldConn.HangUp(10 * 1000);
Thread.Sleep(SysConfig.RasHangUpSleepTime);
if (RasConnection.GetActiveConnectionById(oldConn.EntryId) != null)
{ Console.WriteLine("结束挂断失败，重新挂断"); goto HANDUPCON;
}
oldConn = null;
Console.WriteLine("结束挂断"); isUp = true;
}
catch (Exception ex)
{ QQHelper.WriteLog("宽带连接挂断失败，" + ex.Message); }
}
CHANGEIP:
try
{ var dt = SqliteHelper.GetDataTable("select * from sys_config"); RasDialer rs = new RasDialer();
if (entryName == "")
{ entryName = dt.Rows[0]["SC_NetEntryName"].ToString();
}
rs.EntryName = entryName;
rs.PhoneBookPath = RasPhoneBook.GetPhoneBookPath(RasPhoneBookType.AllUsers);
rs.Credentials = new NetworkCredential(dt.Rows[0]["SC_NetUser"].ToString(), dt.Rows[0]["SC_NetPwd"].ToString());
dt.Dispose();
rs.Dial();
rs.Dispose();
}
catch (Exception ex)
{ QQHelper.WriteLog("宽带连接拨号失败，" + ex.Message); Thread.Sleep(SysConfig.DialFaildSleepTime);
goto CHANGEIP;
}
if (oldConn != null)
{ string ipAddresses = "";
GetIPAddress(out ipAddresses, out oldConn);
oldConn = null;
if (oldIpAddress == ipAddresses)
{ QQHelper.WriteLog("IP和上次重复，重新拨号"); Thread.Sleep(SysConfig.DialFaildSleepTime);
goto HANDUPCON;
}
else
{ if (historyIps.Contains(ipAddresses))
{ QQHelper.WriteLog("IP和前" + SysConfig.IPLoopCount + "次重复，重新拨号"); Thread.Sleep(SysConfig.DialFaildSleepTime);
goto HANDUPCON;
}
if (historyIps.Count >= SysConfig.IPLoopCount)
{ historyIps.RemoveAt(0);
historyIps.Add(ipAddresses);
}
historyIps.Add(ipAddresses);
}
QQHelper.WriteLog("现在的IP是" + ipAddresses); }
SysConfig.IsChangeIp = false;
}
切换IP操作
private void GetIPAddress(out string ipAddress, out RasConnection oldConn)
{ oldConn = null;
ipAddress = "";
var conns = RasConnection.GetActiveConnections();
foreach (var conn in conns)
{ if (conn.Device.DeviceType.ToLower() == "pppoe")
{ oldConn = conn;
break;
}
}
conns = null;
if (oldConn != null)
{ try
{ RasIPInfo ipAddresses = (RasIPInfo)oldConn.GetProjectionInfo(RasProjectionType.IP);
ipAddress = ipAddresses.IPAddress.ToString();
ipAddresses = null;
}
catch { } }
}

题外话:由于最近失业了,呵呵,说大了,是离职,有很多事情需要处理交接,关于QQ 群组广告的源代码,不是我不放出来,主要由于一些代码涉及到公司版权,我不可能不做任何改变就放出来,有保密协议,我需要整理和修改一些代码的实现,以避免这些冲突,望大家理解
