使用 .htaccess 将 URL example.com/mobile 更改为 m.example.com

tag-icon • tag-icon .htaccess rewrite
使用 .htaccess 将 URL example.com/mobile 更改为 m.example.com

我正在设置一个社交网络脚本，它有桌面版和移动版网站。当移动设备尝试浏览该网站时，移动页面将使用网址 www.example.com/mobile 提供。我想要一个 .htaccess 重写规则，可以更改所有www.example.com/mobile网址m.example.com无需真正重定向到子域 m 这是我能想到的

RewriteCond %{HTTP_HOST} ^m.example.com RewriteRule (.*) http://www.example.com/mobile/$1 [R=301,L]

但是我收到了一个错误...Rewitecond: Bad flag delimiters我该如何解决这个问题或者有什么更好的方法吗？

PS 我没有 .htaccess 文件，我直接在 httpd.conf 指令中设置这些规则。我认为这不会有什么不同，但我认为最好提一下……以防万一。

此后，我已将启用的 .htaccess 移出，并从 httpd.conf 文件中取出重写规则，并测试 .htaccess 是否有效以及 mod_rewrite 是否已启用。我使用此代码来验证 mod_rewrite 确实已启用

<?php
ob_start();
phpinfo(INFO_MODULES);
$contents = ob_get_contents();
ob_end_clean();
var_dump(strpos($contents, 'mod_rewrite') !== false);
?>

当我运行此文件时，我得到一个输出bool(true)另外我注意到像下面这样的重写规则工作正常

# 301 redirect if missing www.
    RewriteCond %{HTTP_HOST} !^$
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteCond %{HTTPS}s ^on(s)|
    RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

但这些规则不起作用

RewriteRule ^link([^/]*).html$ rewrite.php?link=$1 [L]
RewriteCond %{HTTP_HOST} ^m.jukpac.com 
RewriteRule (.*) http://www.jukpac.com/mobile/$1 [R=301,L]

为什么我的重写规则仅部分起作用？:-/

答案1

看起来你得到了一个解析错误，因为 RewriteCond 语句试图解释[R=301,L]，尽管那个语句是用于的RewriteRule。

尝试将它们放在不同的行上，如下所示：

 RewriteCond %{HTTP_HOST} ^m.example.com     
 RewriteRule (.*)    http://www.example.com/mobile/$1 [R=301,L]
