今天面试问我怎么获取客户端IP,我一时答不上来,惭愧.

获取服务器电脑名：Page.Server.ManchineName

获取用户信息：Page.User

获取客户端电脑名：Page.Request.UserHostName

获取客户端电脑IP：Page.Request.UserHostAddress

获得前一个IP地址:document.referrer

C#获得IP:using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Collections.Specialized; public partial class test_getIP : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Write(Request.UserHostAddress); Response.Write(Request.UserHostName); Response.Write(Server.MachineName); Response.Write(Page.User.Identity.Name); //C#获得上一个ip的方法 if(Request.ServerVariables["HTTP_REFERER"]!=null) Response.Write(Request.ServerVariables["HTTP_REFERER"].ToString()); //csdn的示例 int loop1, loop2; NameValueCollection coll; coll = Request.ServerVariables; String[] arr1 = coll.AllKeys; for (loop1 = 0; loop1 < arr1.Length; loop1++) { Response.Write("Key: " + arr1[loop1] + "<br>"); String[] arr2 = coll.GetValues(arr1[loop1]); for (loop2 = 0; loop2 < arr2.Length; loop2++) { Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>"); } } } } js获取IP:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>javascript获得IP的方法</title> <script type="text/javascript"> function f(){ alert(1); } //类似C#的委托,用函数名做参数 function f1(m){ m(); } document.onclick=function(){ f1(f); //获取上一个IP alert(GetLocalIPAddress()); alert(document.referrer); } //在【Internet 选项】中【安全】->【ActiveX 控件和插件】-> //【对没有标记为安全的 ActiveX 控件进行初始化和脚本运行】设置为【启用】 //此法不成功 function GetLocalIPAddress(){ var obj = null; var rslt = ""; try { obj = new ActiveXObject("rcbdyctl.Setting"); rslt = obj.GetIPAddress; obj = null; } catch(e) { //异常发生 } return rslt; } </script> </head> <body> <a href="getIP.aspx">getIP</a> </body> </html>
