Question

我有这样的自定义网址：

website.com/show/9999/page-name/

我试图想出一个重写规则来将其转换为：

/show/

请注意，这是一个WordPress网站，<IfModule mod_rewrite.c> Options -MultiViews RewriteEngine On RewriteBase / RewriteRule ^show/(.*)$ /show/?id=$1 [R=301,NC,QSA] RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule>是WP页面名称。

这是我在.htaccess中使用的规则：

website.com/show/?id=9999

这是有效的;它会将website.com/show/9999/重写为RewriteRule ^show/(.*)/(.*)$ /show/?id=$1&n=$2 [R=301,NC,QSA]。

然后我修改了第二个查询字符串的规则：

website.com/show/9999/page-name/

但现在website.com/show/9999/?n=page-name会返回404错误。如果我去：website.com/show/?id=9999&n=page-name，它就可以了。

我做错了什么？

更新

404问题is now solved。

但是，现在我需要重定向旧的查询字符串URL：

website.com/show/9999/page-name

到新的SEO友好网址：

    private static double distance(double lat1, double lon1, double lat2, double lon2, String unit) {
        double theta = lon1 - lon2;
        double dist = Math.sin(deg2rad(lat1)) * Math.sin(deg2rad(lat2)) + Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2)) * Math.cos(deg2rad(theta));
        dist = Math.acos(dist);
        dist = rad2deg(dist);
        dist = dist * 60 * 1.1515;
        if (unit == "K") {
            dist = dist * 1.609344;
        } else if (unit == "N") {
            dist = dist * 0.8684;
        }

        return (dist);
    }


    private static double deg2rad(double deg) {
        return (deg * Math.PI / 180.0);
    }


    private static double rad2deg(double rad) {
        return (rad * 180 / Math.PI);
    }

如何设置重定向？

Answer 1

试试这个：

Options +FollowSymLinks

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteBase /

    RewriteRule ^show/(\d+)/?([^/]*)/?$ /show/?id=$1&n=$2 [L,NC,QSA]

    # Wordpress defaults:
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
## Results
# show/9999            => show/?id=9999&n=
# show/9999/           => show/?id=9999&n=
# show/9999/page-name  => show/?id=9999&n=page-name
# show/9999/page-name/ => show/?id=9999&n=page-name

如您所见，当page-name不可用时，将会有一个空的n查询字符串参数。在PHP脚本中，不要使用isset()检查参数是否存在，请尝试使用empty()。

最后一点;上述规则不会重定向请求，它会将请求映射到引擎盖下，以便URL保持干净。如果您需要重定向，只需添加R标记即可。

404

即使您删除自定义重写规则，您也会从WordPress获得404。这是因为，如你所说，重写目标（/show）是一个WordPress页面，最终会映射到index.php文件。然后，WordPress检查其数据库以查看它是否可以找到具有该路径的页面，或者如果它不能，则抛出404。显然，后者就是你的情况。

更新

关于your recent update;要将旧URL重定向到新URL，您需要一些重写规则：

Options +FollowSymLinks

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteBase /

    RewriteCond %{QUERY_STRING} ^id=(\d+)(&n=)?(.*)$
    RewriteRule ^show/?$ /show/%1/%3 [R=301,QSD,L]

    # Wordpress default rules:
    # ...
</IfModule>
## Results
# show?id=9999              => show/9999
# show?id=9999&n=page-name  => show/9999/page-name
# show/?id=9999&n=page-name => show/9999/page-name

不要使用[R=301]，直到您100％确定所有内容都能正常运行，因为它会被浏览器主动缓存。

Answer 2

我想我几乎已经弄明白了。

@sepehr是正确的，WordPress正在检查，没有找到页面，并抛出404.所以我需要使用WordPress自己的重写引擎来定义重写规则，以便它识别我在做什么。

所以我把它添加到我的WordPress主题的functions.php文件中：

add_action( 'init', 'init_custom_rewrite' );

function init_custom_rewrite() {
    add_rewrite_rule( 
        '^show/([^/]*)/([^/]*)/?',        
        'index.php?page_id=2382&id=$matches[1]&n=$matches[2]',        
        'top' 
    );
}

add_filter('query_vars', 'my_query_vars', 10, 1);

function my_query_vars($vars) {
    $vars[] = 'id';
    $vars[] = 'n';
    return $vars;
}

现在，网址website.com/show/9999/page-name正常运行，而不是投放404。

_{但是，现在我需要将旧的查询字符串URL重定向到这个新的查询字符串。请参阅我的updated question。}

更新

以下是将旧查询字符串URL重定向到新的SEO友好URL的重写规则：

RewriteCond %{QUERY_STRING} ^id=([^/]*)&n=([^/]*)$ 
RewriteRule ^show/?$ /show\/%1\/%2\/? [R=301,L]
