MOD_REWRITE条件重定向

Question

我在使用Apache Mod_Rewrite模块时遇到了问题，

我从get请求中检索三个变量

$country
$state
$location

我成功地在本地重写了url，例如url

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

我想做的是，我想要重定向

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

在以下情况下

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

我正在使用下面的RewriteRule

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

如果我想只显示国家/地区页面，如何重写国家/地区和州/省/市/自治区/省/自治区/市/自治区/市/自治区/省/自治区/自治区/市/自治区/省/自治区/自治区/市/自治区/省/自治区。

非常感谢！请通过提供在线教程和其他参考资料来帮助我。

同样的，我将非常感谢你..:)

您可以使用向下流来识别URL是否是国家/地区、州或位置，如下所示：

<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>

请注意我是如何从最长、最动态的URL开始的。

虽然我发现在PHP解析端处理一个php页面上的所有动态URL流量更容易，但在你的例子中，像result.php这样的东西，你可以确定输出，而且你不必担心在文件上跳来跳去。

.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]
