只要写一个servlet来调用这个类的getMACAddress(String netip)方法就可以获得客户端的mac地址了,相信你会写jsp应该对servlet也不陌生吧,在jsp中调用servlet通过session传递返回的mac地址,加以判断就可以了
mac地址是可以通过注册表修改的,不建议以此来作为限制依据~ --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- 学习,,帮上上上楼顶 --------------------编程问答-------------------- --------------------编程问答-------------------- 用js实现 --------------------编程问答-------------------- 用Runtime.getRuntime().exec()
执行 ipconfig 命令 然后自己截取字符串吧
--------------------编程问答-------------------- 楼上说的这些都仅限于win32平台,而且还得是英文的CMD显示,
ipad,手机,部分中文显示的CMD,都是限制条件, --------------------编程问答-------------------- goooooooooood --------------------编程问答-------------------- 2楼的这个方法不错,长见识了,不过这如果是高并发的话,只怕系统就要给搞宕了。 --------------------编程问答-------------------- 这个要做到比较通用的话,得通过客户端本地程序来获取,如:ActiveX插件或JavaApplet。
