Asp.net中Request.Url的各个属性对应的意义介绍

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://www.zzvips.com/virtual/urldemo.aspx?id=2#top
2.编写简单的代码

复制代码代码如下:

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

3.输出结果
　　Request.ApplicationPath:/virtual
　　Request.PhysicalPath:E:\VsProject\201200420\UrlDemo\UrlDemo\urldemo.aspx
　　DirectoryName:E:\VsProject\201200420\UrlDemo\UrlDemo
