MOD_REWRITE 条件重定向

Question

我在使用 Apache Mod_Rewrite 模块时遇到问题，

我正在从 get 请求中检索三个变量

$country
$state
$location

本地重写url成功 例如网址

localhost/directory/country/state/location /*is redirected to*/
localhost/directory/result.php?c=country&s=state&l=location

我想做的是我要重定向

localhost/directory/country to localhost/directory/country.php?c=country

如果是

localhost/directory/country/state to localhost/directory/state.php?c=country&s=state

我正在使用以下 RewriteRule

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)$ result.php?s=$1&d=$2&l=$3 [L]

如果我想只显示国家页面，我该如何重写国家和州，以及如果我只想显示国家页面..

非常感谢！！ 请通过提供在线教程和其他参考资料来帮助我。

我非常有义务为您提供同样的服务.. :)

您可以使用向下流动来识别网址是国家、州还是位置 类似于：

<IfModule mod_rewrite.c>
    Rewrite Engine On
    RewriteRule ^localhost/directory/([^/\.]+)/([^/\.]+)/([^/\.]+)/ localhost/directory/result.php?c=$1&s=$2&l=$3 [L]
    RewriteRule ^localhost/directory/([^/\.]+)/([^/\.]+)/ localhost/directory/state.php?c=$1&s=$2 [L]
    RewriteRule ^localhost/directory/([^/\.]+)/ localhost/directory/country.php?c=$1 [L]
</IfModule>

请注意我是如何首先从最长、最动态的 URL 开始的。如果您从最短的第一个开始，在您的情况下为 country，那么 URL_Rewrite 将首先接受 answer，而您将永远不会遇到其他两个重写。

虽然我发现在 PHP 解析方面更容易处理一个 php 页面上的所有动态 URL 流量，但在你的情况下，像 result.php 这样你就可以确定输出，而且你不必担心跳转围绕文件。

.htaccess

<IfModule mod_rewrite.c>
    Rewrite Engine On
    RewriteRule ^localhost/directory/([^/\.]+)/([^/\.]+)/([^/\.]+)/ localhost/directory/result.php?c=$1&s=$2&l=$3 [L]
    RewriteRule ^localhost/directory/([^/\.]+)/([^/\.]+)/ localhost/directory/result.php?c=$1&s=$2 [L]
    RewriteRule ^localhost/directory/([^/\.]+)/ localhost/directory/result.php?c=$1 [L]
</IfModule>

result.php

<?php
$location = isset($_GET['l']) ? $_GET['l'] : false;
$state    = isset($_GET['s']) ? $_GET['s'] : false;
$country  = isset($_GET['c']) ? $_GET['c'] : false;

// ...PARSE THE REST OF PHP based off of these variables
?>

我认为，你可以使用两条规则：

# localhost/directory/country
RewriteRule ^[^/]+/([^/]+)$  localhost/directory/country.php?c=$1 [L]

# localhost/directory/country/state
RewriteRule ^[^/]+/([^/]+)/([^/]+)$  localhost/directory/state.php?c=$1&s=$2 [L]
