htaccess - 使用查询字符串将子域的请求重写到文件夹
我正在尝试使用 Apache htaccess 文件进行子域重写，并且需要一些帮助。
我正在尝试获取对 http://xyz.example.com 的请求，内部处理就像用户请求http： //example.com/xyz 因此用户不会在地址栏中看到此 URL - 他们会看到子域版本。
这有点复杂，因为以下的任何内容也也需要传递，例如，如果用户请求http://xyz.example.com /test/word/?x=123 那么这需要由服务器处理，就好像他们访问了http://example.com/xyz/test/word /?x=123。
该网站在 Code Igniter 框架上运行，该框架也有自己的 htaccess 规则，但我想在这些规则生效之前将首先完成此重写。
任何帮助将不胜感激！
I'm trying to get a subdomain rewrite working using an Apache htaccess file and need some help please.
I am trying to get requests for http://xyz.example.com internally handled as if the user had requested http://example.com/xyz so the user does not see this URL in their address bar - they see the subdomain version.
This is slightly complicated by the fact that anything following this also needs to be passed too, for example if the user requests http://xyz.example.com/test/word/?x=123 then this needs to be handled by the server as if they had visited http://example.com/xyz/test/word/?x=123.
The site is running on the Code Igniter framework, which had its own htaccess rules too, but I guess this rewrite would be done first before those kick in.
Any help would be greatly appreciated!

以下 mod_rewrite 规则集应执行您需要的重写：
查询字符串会自动传递，因为我们在重写中没有更改它。
不过，要让 CodeIgnitor 接受此更改，您需要使用
PATH_INFO作为路由信息的来源。为此，您的$config['uri_protocol']需要设置为PATH_INFO或AUTO，并且您的 CodeIgnitorRewriteRule应如下所示：如果您在尝试使用
PATH_INFO时遇到问题，则需要找到一种方法让 CodeIgnitor 解析$_SERVER['REDIRECT_URL ']（并将L标志添加到第一个RewriteRule中）。希望这不是必要的，但如果你不能让它工作，否则我会研究你如何做到这一点。The following mod_rewrite rule set should perform the rewriting you need:
The query string gets passed along automatically, since we haven't changed it in the rewrite.
For CodeIgnitor to pick this change up though, you'll need to be using
PATH_INFOas the source of the routing information. Your$config['uri_protocol']needs to be set toPATH_INFOorAUTOfor this to be the case, and your CodeIgnitorRewriteRuleshould look something like the following:If you run into trouble trying to use
PATH_INFO, you'll need to find a way to get CodeIgnitor to parse$_SERVER['REDIRECT_URL'](and add theLflag to the firstRewriteRuleup there). Hopefully this shouldn't be necessary, but if you can't get it to work otherwise I'll look into how you might do that.
