  • asp.net获取URL和IP地址

    HttpContext.Current.Request.Url.ToString() 并不可靠。

    如果当前URL为 
    http:    //localhost/search.aspx?user=http://csharp.xdowns.com&tag=%BC%BC%CA%F5 

    通过HttpContext.Current.Request.Url.ToString()获取到的却是 

    http:    //localhost/search.aspxuser=http://csharp.xdowns.com&tag=¼¼Êõ 


    正确的方法是：HttpContext.Current.Request.Url.PathAndQuery
    1、通过ASP.NET获取
    如果测试的url地址是http:    //www.test.com/testweb/default.aspx, 结果如下：
    Request.ApplicationPath:                /testweb
    Request.CurrentExecutionFilePath:           /testweb/default.aspx
    Request.FilePath:                           /testweb/default.aspx
    Request.Path:                               /testweb/default.aspx
    Request.PhysicalApplicationPath:        E:\WWW\testwebRequest.PhysicalPath:                   E:\WWW\testweb\    default.aspx
    Request.RawUrl:                             /testweb/default.aspx
    Request.Url.AbsolutePath:                   /testweb/default.aspx
    Request.Url.AbsoluteUrl:                http:    //www.test.com/testweb/default.aspx
    Request.Url.Host:                       www.test.com
    Request.Url.LocalPath:                      /testweb/default.aspx 

    2、通过JS获取

    <table width=100% cellpadding=0 cellspacing=0 border=0 >

    <script> 

    thisURL     = document.URL; 

    thisHREF     = document.location.href; 

    thisSLoc     = self.location.href; 

    thisDLoc     = document.location; 

    strwrite     = "<tr><td valign=top>thisURL: </td><td>[" + thisURL + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisHREF: </td><td>[" + thisHREF + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisSLoc: </td><td>[" + thisSLoc + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisDLoc: </td><td>[" + thisDLoc + "]</td></tr>" 

    document.write( strwrite ); 

    </script> 

    thisDLoc     = document.location; <BR>

    thisURL     = document.URL; <BR>

    thisHREF     = document.location.href; <BR>

    thisSLoc     = self.location.href;<BR>

    <script> 

    thisTLoc     = top.location.href; 

    thisPLoc     = parent.document.location; 

    thisTHost     = top.location.hostname; 

    thisHost     = location.hostname; 

    strwrite     = "<tr><td valign=top>thisTLoc: </td><td>[" + thisTLoc + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisPLoc: </td><td>[" + thisPLoc + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisTHost: </td><td>[" + thisTHost + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisHost: </td><td>[" + thisHost + "]</td></tr>" 

    document.write( strwrite ); 

    </script> 

    thisTLoc     = top.location.href; <BR>

    thisPLoc     = parent.document.location; <BR>

    thisTHost     = top.location.hostname; <BR>

    thisHost     = location.hostname;<BR>

    <script> 

    tmpHPage     = thisHREF.split( "/" ); 

    thisHPage     = tmpHPage[ tmpHPage.length-1 ]; 

    tmpUPage     = thisURL.split( "/" ); 

    thisUPage     = tmpUPage[ tmpUPage.length-1 ]; 

    strwrite     = "<tr><td valign=top>thisHPage: </td><td>[" + thisHPage + "]</td></tr>" 

    strwrite     += "<tr><td valign=top>thisUPage: </td><td>[" + thisUPage + "]</td></tr>" 

    document.write( strwrite ); 

    </script><tr><td>

    获取IP
    1、ASP.NET中获取

    获取服务器的IP地址： 
    using System.Net; 

    string myIP,myMac;
    System.Net.IPAddress[] addressList     = Dns.GetHostByName(Dns.GetHostName()).AddressList; 
    if ( addressList.Length>1) 
    {
     myIP     = addressList[0].ToString(); 
     myMac     = addressList[1].ToString(); 
    }     
    else 
    { 
     myIP     = addressList[0].ToString(); 
     myMac     = "没有可用的连接"；
    }     
    myIP地址就是服务器端的ip地址。

    获取客户端的ip地址，可以使用

    //获取登录者ip地址
    string ip = Request.ServerVariables["REMOTE_ADDR"].ToString(); 
    2、通过JS获取
    <html>
    <head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=gbk">
    </head>

    <body>

    <object classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" id="locator" style="display:none;visibility:hidden"></object>
    <object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo" style="display:none;visibility:hidden"></object>                                                         

    <form name="myForm">
         <br/>MAC地址：<input type="text" name="macAddress">
         <br/>IP地址：<input type="text" name="ipAddress">
         <br/>主机名：<input type="text" name="hostName">
    </form>

    </body>
    </html>
    <script language="javascript">
     var sMacAddr    ="";
     var sIPAddr    ="";
     var sDNSName    ="";

     var service     = locator.ConnectServer();
     service.Security_.ImpersonationLevel    =3;
     service.InstancesOfAsync(foo,     'Win32_NetworkAdapterConfiguration');

    </script>

    <script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">
                if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true){
                                  if(objObject.IPEnabled && objObject.IPAddress(0) !=null && objObject.IPAddress(0) != "undefined")
                                            sIPAddr     = objObject.IPAddress(0);
                                  if(objObject.MACAddress != null &&objObject.MACAddress != "undefined")
                        sMacAddr     = objObject.MACAddress;
                                  if(objObject.DNSHostName != null &&objObject.DNSHostName != "undefined")
                                            sDNSName     = objObject.DNSHostName;
             }
    </script>

    <script FOR="foo" EVENT="OnCompleted(hResult,pErrorObject, pAsyncContext)" LANGUAGE="JScript">

           myForm.macAddress.value    =sMacAddr;
     myForm.ipAddress.value    =sIPAddr;
           myForm.hostName.value    =sDNSName;
    </script>
