ADSL 拨号实现

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http://dotras.codeplex.com/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

切换IP操作

  private void GetIPAddress(out string ipAddress, out RasConnection oldConn)

                    oldConn = conn;
                    break;
                }
            }
            conns = null;
            if (oldConn != null)
            {
                try
                {
                    RasIPInfo ipAddresses = (RasIPInfo)oldConn.GetProjectionInfo(RasProjectionType.IP);
                    ipAddress = ipAddresses.IPAddress.ToString();
                    ipAddresses = null;
                }
                catch { }


            }
