  • asp.net中获取当前url的方法

    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

    Request.Url.PathAndQuery

    string 类型。等于 Request.Url.AbsolutePath 和 Request.Url.Query 相加。

    Request.Url.AbsolutePath

    string 类型。指当前页面 URL 的绝对路径,不包括查询字符串部分。

    示例:/test/Default.aspx

    Request.Url.Query

    string 类型。指当前页面 URL 的查询字符串,从“?”开始。

    示例:?a=1&b=2

    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 estwebRequest.PhysicalPath:                   E:WWW estwebdefault.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

     

    URL http://localhost:1897/News/Press/Content.aspx/123?id=1#toc
    Request.ApplicationPath /
    Request.PhysicalPath D:ProjectsSolutionwebNewsPressContent.aspx
    System.IO.Path.GetDirectoryName(Request.PhysicalPath) D:ProjectsSolutionwebNewsPress
    Request.PhysicalApplicationPath D:ProjectsSolutionweb
    System.IO.Path.GetFileName(Request.PhysicalPath) Content.aspx
    Request.CurrentExecutionFilePath /News/Press/Content.aspx
    Request.FilePath /News/Press/Content.aspx
    Request.Path /News/Press/Content.aspx/123
    Request.RawUrl /News/Press/Content.aspx/123?id=1
    Request.Url.AbsolutePath /News/Press/Content.aspx/123
    Request.Url.AbsoluteUri http://localhost:1897/News/Press/Content.aspx/123?id=1
    Request.Url.Scheme http
    Request.Url.Host localhost
    Request.Url.Port 1897
    Request.Url.Authority localhost:1897
    Request.Url.LocalPath /News/Press/Content.aspx/123
    Request.PathInfo /123
    Request.Url.PathAndQuery /News/Press/Content.aspx/123?id=1
    Request.Url.Query ?id=1
    Request.Url.Fragment  
    Request.Url.Segments

    /
    News/
    Press/
    Content.aspx/

    123

    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" ></object>
    <object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo" ></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>
