1.获取当前完整网址

 
<script type="text/javascript"> 
thisURL = document.URL; 
thisHREF = document.location.href; 
thisSLoc = self.location.href; 
thisDLoc = document.location; 
strwrite = " thisURL:  [" + thisURL + "]<br />" 
strwrite += " thisHREF:  [" + thisHREF + "]<br />" 
strwrite += " thisSLoc:  [" + thisSLoc + "]<br />" 
strwrite += " thisDLoc:  [" + thisDLoc + "]<br />" 
document.write( strwrite ); 
</script>

 

 

 

 
2.获取当前域名信息
 

<script type="text/javascript">
thisTLoc = top.location.href; 
thisPLoc = parent.document.location; 
thisTHost = top.location.hostname; 
thisHost = location.hostname; 
strwrite = "  thisTLoc:  [" + thisTLoc + "]<br />" 
strwrite += " thisPLoc:  [" + thisPLoc + "]<br />" 
strwrite += " thisTHost:  [" + thisTHost + "]<br />" 
strwrite += " thisHost:  [" + thisHost + "]<br />" 
document.write( strwrite );  
 </script>

 

 
 

 

 3.获取当前页面

 
<script type="text/javascript"> 
tmpHPage = thisHREF.split( "/" ); 
thisHPage = tmpHPage[ tmpHPage.length-1 ]; 
tmpUPage = thisURL.split( "/" ); 
thisUPage = tmpUPage[ tmpUPage.length-1 ]; 
strwrite = " thisHPage:  [" + thisHPage + "]<br />" 
strwrite += " thisUPage:  [" + thisUPage + "]<br />" 
document.write( strwrite ); 
</script>

 

获取网站的IP地址的方法有很多，最常用的便是使用CMD命令中的ping命令，ping命令也是最常用的网络命令
 
使用ping命令获取网站的Ip地址的格式：ping +  网站的域名
 
如获取百度的IP地址的方式： ping +  www.baidu.com
 
测试效果：
 
打开CMD
 
 

 
 
输入 ping  www.baidu.com后单击回车
 
 

 
 
通过Winscoket编程的方式也可以获取网站的IP地址
 
程序代码：
 

#include <stdio.h>
#include <stdlib.h>
#include <winsock2.h>

//连接Winsock库
#pragma comment(lib, "ws2_32.lib")

void main()
{
    //调用WSAtartup初始化Winsock库
    WSADATA wsaData;
    ::WSAStartup(
        MAKEWORD(2,2),//版本号为2.2
        &wsaData
        );

    char szHost[256];//存放域名或服务器名

    printf("请输入需要解析的域名：");
    scanf("%s", szHost);

    hostent *pHost = ::gethostbyname(szHost);//通过主机名得到地址信息

    //一个主机可能有多个网卡、多个IP、下面的代码输出所有的IP地址
    in_addr addr;

    for(int i=0; ; i++)
    {
        //获得地址(网络字节)
        char *p = pHost->h_addr_list[i];

        if(NULL == p)
        {
            break;//退出循环
        }

        //将地址拷贝到in_addr结构体中
        memcpy(&addr.S_un.S_addr, p, pHost->h_length);

        //将in_addr转换为主机字节序
        char *strIP = ::inet_ntoa(addr);

        //打印IP地址
        printf("%s的第%d个IP地址是:: %s\n", szHost, i+1, strIP);
    }

    system("pause");
}

 
 
执行结果：
 

1.复制网站网址
 
 2.win+r打开cmd命令提示符
 
 3.ping + 地址 回车
 
 

System.Web.HttpContext.Current.Request.Url.Scheme + "://" + System.Web.HttpContext.Current.Request.Url.Authority;
