Python利用WMI实现ping命令的例子

WMI是Windows系统的一大利器，Python的win32api库提供了对WMI的支持，安装win32api即可使用 WMI。

本例通过WMI的WQL实现ping命令。

import wmi
c = wmi.WMI()
wql = "SELECT StatusCode FROM Win32_PingStatus WHERE Address = '127.0.0.1'"

for i in c.query(wql):
 if i.StatusCode:
   print 'offline'
 else:
   print 'online'

c.query(wql)的结构如下，其中StatusCode为0表示能够ping通，大于0表示ping不通

instance of Win32_PingStatus
{
 Address = "127.0.0.1";
 BufferSize = 32;
 NoFragmentation = FALSE;
 RecordRoute = 0;
 ResolveAddressNames = FALSE;
 SourceRoute = "";
 SourceRouteType = 0;
 StatusCode = 0;
 Timeout = 1000;
 TimestampRoute = 0;
 TimeToLive = 128;
 TypeofService = 128;
};
