如何通过标准方式从客户端URL（request.urlreferrer）获取域名和文件夹名称 [英] How to get domain name and folder name from client url (request.urlreferrer) by standard way

问题描述

我需要从Request.UrlReferrer获取域名和文件夹名称。如果像http://example.com/folder1/folder2/page.aspx?query1=123&query2=456这样的网址意味着我需要获取http://example.com/folder1/folder2/或 folder1 / folder2 /，使用uri或其他标准方法。



我尝试过：

i need to get domain name and folder name from a Request.UrlReferrer. if the url like "http://example.com/folder1/folder2/page.aspx?query1=123&query2=456" means i need to get "http://example.com/folder1/folder2/" or "folder1/folder2/", by using uri or other standard method.

What I have tried:

string hostedFolder = urlReferrer.LocalPath.Replace(urlReferrer.Segments[urlReferrer.Segments.Length - 1], "");

推荐答案

您可以使用Uri类：

You could use the Uri class:

string url = @"http://example.com/folder1/folder2/page.aspx?query1=123&query2=456";
            Uri uri = new Uri(url);

然后 uri.LocalPath 会给你 /folder1/folder2/page.aspx

你可以使用 Path.GetDirectoryName（uri.LocalPath） ）只提供文件夹： \ folder1 \ folder2

Then uri.LocalPath will give you /folder1/folder2/page.aspx
And you could use Path.GetDirectoryName(uri.LocalPath) to give you just the folders: \folder1\folder2

Request.ApplicationPath 应该为您提供Web根相对逻辑路径。此外，如果您想处理URL中的某些段，那么您可能希望使用 string.Split 方法执行简单的字符串操作。

Request.ApplicationPath should give you the web root-relative logical path. Also, if you want to work on certain segments from the URL, then you might want to do a simple string manipulation instead using string.Split method.
