JavaScript 获取客户端计算机硬件及系统信息

来源：互联网发布：ntfs for mac 10.11 编辑：程序博客网时间：2024/06/02 04:14

通过WMI来实现获取客户端计算机硬件及系统信息:

//系统信息获取
2

function getSysInfo(){
3

var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
4

var service = locator.ConnectServer(".");
5

//CPU信息
6

var cpu = new Enumerator (service.ExecQuery("SELECT * FROM Win32_Processor")).item();
7

var cpuType=cpu.Name,hostName=cpu.SystemName;
8

//内存信息
9

var memory = new Enumerator (service.ExecQuery("SELECT * FROM Win32_PhysicalMemory"));
10

for (var mem=[],i=0;!memory.atEnd();memory.moveNext()) mem[i++]={cap:memory.item().Capacity/1024/1024,speed:memory.item().Speed}
11

//系统信息
12

var system=new Enumerator (service.ExecQuery("SELECT * FROM Win32_ComputerSystem")).item();
13

var physicMenCap=Math.ceil(system.TotalPhysicalMemory/1024/1024),curUser=system.UserName,cpuCount=system.NumberOfProcessors
14

return {cpuType:cpuType,cpuCount:cpuCount,hostName:hostName,curUser:curUser,memCap:physicMenCap,mem:mem}
16

}

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：

Win32_Processor // CPU 处理器

Win32_PhysicalMemory // 物理内存

Win32_Keyboard // 键盘

Win32_DiskDrive // 硬盘驱动器

Win32_CDROMDrive // 光盘驱动器

document.write("</table>");

另外，通过以下方式也可以获得系统的相关信息：

<HTML><HEAD><TITLE>WMI Scripting HTML</TITLE>
<META http-equiv=Content-Typecontent="text/html; charset=gb2312">
<SCRIPT language=JScript event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for=foo>
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
//document.formbar.submit();
  </SCRIPT>

<SCRIPT language=JScript event=OnObjectReady(objObject,objAsyncContext)for=foo>
   if(objObject.IPEnabled!=null&& objObject.IPEnabled!="undefined"&& objObject.IPEnabled==true)
    {
    if(objObject.MACAddress!=null&& objObject.MACAddress!="undefined")
     MACAddr = objObject.MACAddress;
    if(objObject.IPEnabled&& objObject.IPAddress(0)!=null&& objObject.IPAddress(0)!="undefined")
     IPAddr = objObject.IPAddress(0);
    if(objObject.DNSHostName!=null&& objObject.DNSHostName!="undefined")
     sDNSName = objObject.DNSHostName;
     }
  </SCRIPT>

<META content="MSHTML 6.00.2800.1106" name=GENERATOR></HEAD>
<BODY>
<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6VIEWASTEXT></OBJECT>
<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
<SCRIPT language=JScript>
   var service= locator.ConnectServer();
   var MACAddr ;
   var IPAddr ;
   var DomainAddr;
   var sDNSName;
    service.Security_.ImpersonationLevel=3;
    service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');
   </SCRIPT>

<FORM id="formfoo" name="formbar" action="index.do" method="post"><INPUTvalue="00-11-11-B4-52-EF"name="txtMACAddr"><INPUT value="210.42.38.50"name="txtIPAddr"><INPUT value="zhupan" name="txtDNSName"></FORM></BODY></HTML>

        其实最关键的还是用到两个ActiveX：
        <OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>
        <OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
        不过这两个ActiveX都是系统自带，不用去下载或注册。
        接下来的工作就是用脚本和ActiveX交互

<HTML>
<head>
  <script language="javascript" type="text/javascript">
      function getCode(){
       var locator = new ActiveXObject("WbemScripting.SWbemLocator");
                var service = locator.ConnectServer(".");
                var properties = service.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled=TRUE");
                var e = new Enumerator(properties);
                document.write("<table border=1>");
                for (; !e.atEnd(); e.moveNext()) {
                  var p = e.item();
                  //if(p.IPAddress(0)!=null && p.IPAddress(0)!="undefined" && p.IPAddress(0)!="0.0.0.0" && p.IPAddress(0)!="127.0.0.1"){
                      document.write("<tr>");
                      document.write("<td>" + p.ServiceName + "</td>");
                      document.write("<td>" + p.MACAddress + "</td>");
                      document.write("<td>" + p.IPAddress(0) + "</td>");
                      document.write("</tr>");
                      //break;
                  //}
                }
                document.write("</table>");
            }
  </script>
</head>
