通过WMI来实现获取客户端计算机硬件及系统信息:
代码实现主要包括这几部分:
先通过new ActiveXObject ("WbemScripting.SWbemLocator"); 访问到WbemScripting对象。
通过locator.ConnectServer("."); 连接我们本地电脑(.代表本地电脑,当然
也可以访问其他计算机)。
通过service.ExecQuery("SELECT * FROM Win32_Processor")这个类似sql的语句(其实系统信息也是存储在计算中一个类似数据库的文件中)获取我们需要的对象的记录集。
通过new Enumerator来创建一个可枚举的对象,下面就可以遍历取信息了。
注意:运行的前提是要修改浏览器安全设置,“允许对未标记为可安全执行的ActiveX
脚本的运行”。
这里主要取了CPU、内存及系统用户几个信息,大家利用WMI的API或者借助JsedIT获取
到更多的信息。下面列出了常用信息的类:
