- Java code
String ip = getRequest().getRemoteAddr();
如何获取mac地址呢？？
如果用JS 在本地获取的话 使用的activeX控件会被阻止 。
JS 代码如下 （a.htm这个页面得到mac）：
- HTML code
<HTML><HEAD><TITLE>WMI Scripting HTML</TITLE><META http-equiv=Content-Type content="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-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT><OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT><SCRIPT language=JScript> var service = locator.ConnectServer(); var MACAddr ; var IPAddr ; var sDNSName; service.Security_.ImpersonationLevel=3; service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');</SCRIPT><FORM id="formfoo" name="formbar" action="index.do" method="post"><INPUT value="00-11-11-B4-52-EF" name="txtMACAddr"> <INPUT value="210.42.38.50" name="txtIPAddr"> <INPUT value="zhupan" name="txtDNSName"> </FORM></BODY></HTML>如果直接在浏览器中运行a.htm 得到mac 但在服务器下会被浏览器阻止（好像是远程访问的时候阻止）
我想问服务器能直接得到mac吗？？ 如果不能 还应该怎么做？
------解决方案--------------------
你获取客户端信息必须使用浏览器ACTIVEX设置启用，客户端的防火墙都可以拦击阻止执行的，客户端你没有办法去控制的（否则就成病毒了）。
------解决方案--------------------
String ip = getRequest().getRemoteAddr(); 你这样写只是得到客户端代理服务器的地址
------解决方案--------------------
- Java code
public static String getMACAddress() { String address = ""; String os = System.getProperty("os.name"); if (os != null && os.startsWith("Windows")) { try { String command = "cmd.exe /c ipconfig /all"; Process p = Runtime.getRuntime().exec(command); BufferedReader br = new BufferedReader(new InputStreamReader(p .getInputStream())); String line; while ((line = br.readLine()) != null) { if (line.indexOf("Physical Address") > 0) { int index = line.indexOf(":"); index += 2; address = line.substring(index); break; } } br.close(); return address.trim(); } catch (IOException e) { } } return address; }
