Using .htaccess to set a sub directory as root directory
提问by Stibily
Is there a way to use htaccess to tell a subdirectory to act as the root for the entire site?
有没有办法使用 htaccess 告诉子目录充当整个站点的根目录？
For example, if I had a website under http://localhost/testsite/and in it's index.php file I had a reference to the stylesheet using the following code..
例如，如果我在http://localhost/testsite/下有一个网站，并且在它的 index.php 文件中，我使用以下代码引用了样式表。
<link rel="stylesheet" type="text/css" href="/css/layout.css" />
Could I then make that load /localhost/testsite/css/layout.css?
然后我可以加载 /localhost/testsite/css/layout.css 吗？
To get around this problem, I set up localhost subdomains for each site which although works, is not ideal.
为了解决这个问题，我为每个站点设置了 localhost 子域，这虽然有效，但并不理想。
Many thanks.
非常感谢。

If you want to keep the 'href="/css/layout.css"' part, then yes, you can set up a rewrite rule. You just have to be careful not to redirect anything starting with /testsite (or you'll end up with a loop).
如果您想保留 'href="/css/layout.css"' 部分，那么是的，您可以设置重写规则。您只需要注意不要重定向以 /testsite 开头的任何内容（否则最终会出现循环）。
Like (in root .htaccess):
喜欢（在根 .htaccess 中）：
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/testsite/.*$
RewriteRule ^(.*)$ /testsite/ [QSA,L]
There, you will be able to access your layout.css file either from:
在那里，您将能够从以下任一方式访问您的 layout.css 文件：
http://localhost/testsite/css/layout.css
http://localhost/testsite/css/layout.css
or
或者

Sure, all relative URIs (as yours) are relative to the base URI which by default is the URI of the document:
当然，所有相对 URI（如您的）都是相对于基本 URI 的，默认情况下它是文档的 URI：
http://localhost/testsite/index.php
You only need to tell which part to add:
您只需要告诉添加哪个部分：
<link rel="stylesheet" type="text/css" href="./css/layout.css" />
^
` see this dot
Example:
例子：
Base URI :: http://localhost/testsite/index.php
Relative URI :: ./css/layout.css
Result :: http://localhost/testsite/css/layout.css
If you need to have this more modular, there are multiple ways to do that. One is to set the base URI explicitly inside the HTML document (see <base>).
如果您需要更模块化，有多种方法可以做到这一点。一种是在 HTML 文档中显式设置基本 URI（请参阅 参考资料<base>）。
Another one is to resolve links relatively on the server-side based on the Request URIand your site's root-path. See this answerfor an example.
另一种方法是根据请求 URI和站点的根路径在服务器端相对解析链接。有关示例，请参阅此答案。
