Asp.net中Request.Url的各个属性对应的意义

　　网络上关于Request.Url的说明已经很多也很丰富了，但是自己还是实践了一下，看看最终的结果与网络上的是否一致。

　　1.简单的环境搭建

　　在本地IIS上配置了一个网站：主机名为wjnhome.com，端口88，然后建了一个虚拟目录指向同一站点，虚拟目录名称为virtual，配置host为127.0.0.1　　wjnhome.com

　　所以地址就为：http://wjnhome.com:88/virtual/urldemo.aspx?id=2#top

　　2.编写简单的代码

    

            //虚拟目录的路径
            Response.Write("<strong>Request.ApplicationPath:</strong>" + Request.ApplicationPath + "</br>");
            //站点的物理路径(完整路径)
            Response.Write("<strong>Request.PhysicalPath:</strong>" + Request.PhysicalPath + "</br>");
            //站点物理路径的目录
            Response.Write("<strong>DirectoryName:</strong>" + System.IO.Path.GetDirectoryName(Request.PhysicalPath) + "</br>");
            //站点物理路径的目录
            Response.Write("<strong>Request.PhysicalApplicationPath:</strong>" + Request.PhysicalApplicationPath + "</br>");
            //当前页面的文件名
            Response.Write("<strong>FileName:</strong>" + System.IO.Path.GetFileName(Request.PhysicalPath) + "</br>");
            //当前页面的虚拟路径
            Response.Write("<strong>Request.CurrentExecutionFilePath:</strong>" + Request.CurrentExecutionFilePath + "</br>");
            //当前页面的虚拟路径
            Response.Write("<strong>Request.FilePath:</strong>" + Request.FilePath + "</br>");
            Response.Write("<strong>Request.Path:</strong>" + Request.Path + "</br>");
            //原始URL
            Response.Write("<strong>Request.RawUrl:</strong>" + Request.RawUrl + "</br>");
            //绝对路径(不包括参数什么的)
            Response.Write("<strong>Request.Url.AbsolutePath:</strong>" + Request.Url.AbsolutePath + "</br>");
            //绝对URL
            Response.Write("<strong>Request.Url.AbsoluteUri:</strong>" + Request.Url.AbsoluteUri + "</br>");
            //URL协议方案
            Response.Write("<strong>Request.Url.Scheme:</strong>" + Request.Url.Scheme + "</br>");
            //URL的主机名
            Response.Write("<strong>Request.Url.Host:</strong>" + Request.Url.Host + "</br>");
            //URL端口号
            Response.Write("<strong>Request.Url.Port:</strong>" + Request.Url.Port + "</br>");
            //主机名+端口号
            Response.Write("<strong>Request.Url.Authority:</strong>" + Request.Url.Authority + "</br>");
            //获取文件名的本地操作系统表现形式
            Response.Write("<strong>Request.Url.LocalPath:</strong>" + Request.Url.LocalPath + "</br>");
            //附加路径信息，例如http://wjnhome.com:88/UrlDemo.aspx/Hello?id=22#top 那么这里就是Hello
            Response.Write("<strong>Request.PathInfo:</strong>" + Request.PathInfo + "</br>");
            //URL的路径和GET参数
            Response.Write("<strong>Request.Url.PathAndQuery:</strong>" + Request.Url.PathAndQuery + "</br>");
            //URL的GET参数
            Response.Write("<strong>Request.Url.Query:</strong>" + Request.Url.Query + "</br>");
            //主要指的是http://wjnhome.com:88/UrlDemo.aspx/Hello?id=22#top中#后面的top。
            //但一般情况下无法获取值，因为浏览器不会把这个值发送到服务器端
            Response.Write("<strong>Request.Url.Fragment:</strong>" + Request.Url.Fragment + "</br>");
            //主机名
            Response.Write("<strong>Request.Url.DnsSafeHost:</strong>" + Request.Url.DnsSafeHost + "</br>");
            //URL的全部
            Response.Write("<strong>Request.Url.OriginalString:</strong>" + Request.Url.OriginalString + "</br>");
            //这种情况 Uri uriAddress = new Uri ("http://user:password@www.contoso.com/index.htm ") Console.WriteLine(uriAddress.UserInfo);
            Response.Write("<strong>Request.Url.UserInfo:</strong>" + Request.Url.UserInfo + "</br>");
            //从某个页面跳转过来的时候会显示源页面的值
            Response.Write("<strong>Request.UrlReferrer:</strong>" + Request.UrlReferrer + "</br>");
            //URI的每一段
            for (var i = 0; i < Request.Url.Segments.Length;i++ )
            {
                Response.Write("<strong>Request.Url.Segment" + i + ":</strong>" + Request.Url.Segments[i] + "</br>");
            }
