Meanings of each attribute of Request. Url in Asp.net
This article Reprinted from http://www.jb51.net/article/30254.htm
The description of Request. Url on the network is already rich, but I have practiced it to check whether the final result is consistent with that on the network.
1. Simple environment setup
On the local IIS, a website is configured with the host Name wjnhome.com, port 88, and a virtual directory pointing to the same site. The virtual directory name is virtual, and the host configuration is 127.0.0.1 wjnhome.com.
So the address is: http://jb51.net: 88/virtual/urldemo. aspx? Id = 2 # top
2. Write simple code
// Virtual directory path
Response. Write ("<strong> Request. ApplicationPath: </strong>" + Request. ApplicationPath + "</br> ");
// The physical path of the site (full path)
Response. Write ("<strong> Request. PhysicalPath: </strong>" + Request. PhysicalPath + "</br> ");
// Directory of the physical path of the site
Response. Write ("<strong> DirectoryName: </strong>" + System. IO. Path. GetDirectoryName (Request. PhysicalPath) + "</br> ");
// Directory of the physical path of the site
Response. Write ("<strong> Request. PhysicalApplicationPath: </strong>" + Request. PhysicalApplicationPath + "</br> ");
// File Name of the current page
Response. Write ("<strong> FileName: </strong>" + System. IO. Path. GetFileName (Request. PhysicalPath) + "</br> ");
// The Virtual Path of the current page
Response. Write ("<strong> Request. CurrentExecutionFilePath: </strong>" + Request. CurrentExecutionFilePath + "</br> ");
// The Virtual Path of the current page
Response. Write ("<strong> Request. FilePath: </strong>" + Request. FilePath + "</br> ");
Response. Write ("<strong> Request. Path: </strong>" + Request. Path + "</br> ");
// Original URL
Response. Write ("<strong> Request. RawUrl: </strong>" + Request. RawUrl + "</br> ");
// Absolute path (excluding parameters or something)
Response. Write ("<strong> Request. Url. AbsolutePath: </strong>" + Request. Url. AbsolutePath + "</br> ");
// Absolute URL
Response. Write ("<strong> Request. Url. AbsoluteUri: </strong>" + Request. Url. AbsoluteUri + "</br> ");
// URL protocol Scheme
Response. Write ("<strong> Request. Url. Scheme: </strong>" + Request. Url. Scheme + "</br> ");
// Host name of the URL
Response. Write ("<strong> Request. Url. Host: </strong>" + Request. Url. Host + "</br> ");
// URL port number
Response. Write ("<strong> Request. Url. Port: </strong>" + Request. Url. Port + "</br> ");
// Host name + port number
Response. Write ("<strong> Request. Url. Authority: </strong>" + Request. Url. Authority + "</br> ");
// Obtain the local operating system representation of the file name
Response. Write ("<strong> Request. Url. LocalPath: </strong>" + Request. Url. LocalPath + "</br> ");
// Additional path information such as http://jb51.net: 88/UrlDemo. aspx/Hello? Id = 22 # top so here is Hello
Response. Write ("<strong> Request. PathInfo: </strong>" + Request. PathInfo + "</br> ");
// URL path and GET Parameter
Response. Write ("<strong> Request. Url. PathAndQuery: </strong>" + Request. Url. PathAndQuery + "</br> ");
// GET parameters of the URL
Response. Write ("<strong> Request. Url. Query: </strong>" + Request. Url. Query + "</br> ");
// Mainly refers to the http://jb51.net: 88/UrlDemo. aspx/Hello? Id = 22 # top in # top next.
// However, the value cannot be obtained normally because the browser does not send the value to the server.
Response. Write ("<strong> Request. Url. Fragment: </strong>" + Request. Url. Fragment + "</br> ");
// Host name
Response. Write ("<strong> Request. Url. DnsSafeHost: </strong>" + Request. Url. DnsSafeHost + "</br> ");
// All URLs
Response. Write ("<strong> Request. Url. OriginalString: </strong>" + Request. Url. OriginalString + "</br> ");
// In this case 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> ");
// The value of the Source Page is displayed when you jump from a page.
Response. Write ("<strong> Request. UrlReferrer: </strong>" + Request. UrlReferrer + "</br> ");
// Each segment of the URI
For (var I = 0; I <Request. Url. Segments. Length; I ++)
{
Response. write ("<strong> Request. url. segment "+ I +": </strong> "+ Request. url. segments [I] + "</br> ");
}
