在 htaccess 中，我想用连字符替换下划线，然后将用户重定向到新网址
我想将包含下划线的任何请求重定向到同一网址，但用连字符替换网址。我看到很多论坛建议我做这样的事情：（
重复此 rewriteRule 的增量版本，直至无数）
rewriteRule ^([^_]*)_([^_]*)_([^_]*)_(.*)$ http://example.com/$1-$2-$3-$4 [R=301,L]
rewriteRule ^([^_]*)_([^_]*)_(.*)$ http://example.com/$1-$2-$3 [R=301,L]
rewriteRule ^([^_]*)_(.*)$ http://example.com/$1-$2 [R=301,L]
我当前在 php 中的解决方案是（效果很好）：
if(preg_match('/[_]+/', $_SERVER['REQUEST_URI'])){
$redirectUrl = preg_replace('/[_]+/','-', $_SERVER['REQUEST_URI']);
header('Location: '. $redirectUrl , TRUE, 301);
return;
}
但是，我宁愿不使用 php & ;相反，将其保留在我的 htaccess 文件中，而不必一遍又一遍地重复第一个 rewriteRule，以便预测每个 url 可能有多少个下划线。想法？有没有一种方法可以在不重复递增的 rewriteRule 的情况下做到这一点？

我当前的 htaccess 文件只是标准的 WordPress 文件，如下：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
I'd like to redirect any request that contains underscores to the same url, but with hyphens replacing the urls. I've seen a lot of forums suggest I do something like this:
(Repeat an incremented version of this rewriteRule up to a gazillion)
rewriteRule ^([^_]*)_([^_]*)_([^_]*)_(.*)$ http://example.com/$1-$2-$3-$4 [R=301,L]
rewriteRule ^([^_]*)_([^_]*)_(.*)$ http://example.com/$1-$2-$3 [R=301,L]
rewriteRule ^([^_]*)_(.*)$ http://example.com/$1-$2 [R=301,L]
My current solution in php is (which works fine):
if(preg_match('/[_]+/', $_SERVER['REQUEST_URI'])){
$redirectUrl = preg_replace('/[_]+/','-', $_SERVER['REQUEST_URI']);
header('Location: '. $redirectUrl , TRUE, 301);
return;
}
But, I'd rather not use php & instead keep it in my htaccess file without having to repeat that first rewriteRule over and over again in order to anticipate how many underscores each url might be. Thoughts? Is there such a way to do this with out repeating the incremented rewriteRule?

My current htaccess file is just the standard WordPress one, which is below:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

请参阅“Next”指令/重写标志，这会导致从第一条规则开始重新评估规则集：http://httpd.apache.org/docs/current/rewrite/flags.html#flag_n
像这样的东西可能会起作用：
See the "Next" directive/rewrite flag, which causes the ruleset to be reevaluated starting with the first rule: http://httpd.apache.org/docs/current/rewrite/flags.html#flag_n
Something like this might work:
如何将 2 结合起来。使用单个重写规则来重写执行替换和重定向的 PHP 脚本。这样您就可以避免多个重写规则，可以处理任意数量的下划线，并且仅在需要时调用 PHP 重定向。
How about combining the 2. Have a single rewrite rule that rewrites to a PHP script that does the substitution and redirect. That way you avoid having multiple rewrite rules, can handle any number of underscores and only invoke the PHP redirection when it is needed.
