hostgator:通配符子域到URL的映射 [英] hostgator: wildcard subdomain mapping to URL

问题描述

过去3个小时，我一直在hostgator共享托管服务器上解决此问题.这是最简单的问题.

I have been struggling with this problem on hostgator shared hosting server for the past 3 hours. This is the problem in the simplest.

这是我想发生的映射: subdomain.domain.com-> www.domain.com/test.php?user=subdomain

This is the mapping i want to happen: subdomain.domain.com --> www.domain.com/test.php?user=subdomain

但是由于某种原因，每当我输入"subdomain.domain.com"时，重定向都不会发生，即使URL在我的浏览器中也不会更改.而且我在加载的页面上看到了test.php文件(因为我在服务器上仅有的文件是.htaccess和test.php).

but for some reason whenever i enter "subdomain.domain.com" the redirection doesn't happen and even the URL doesn't change in my browser. And I see test.php file listed on loaded page (because The only files i have on server are .htaccess and test.php).

这是.htacess代码

This is the .htacess code

     <IfModule mod_rewrite.c>
            RewriteEngine On
            RewriteBase /

            <IfModule mod_proxy.c>
                    RewriteCond %{HTTP_HOST} !^www. [NC]
                    RewriteCond %{HTTP_HOST} ^([a-z0-9]+).domain.com(.*)$ [NC]
                    RewriteRule ^(.*)$ http://www.domain.com/test.php?user=$1$2 [P,L]
            </IfModule>

            <IfModule !mod_proxy.c>
                    RewriteCond %{HTTP_HOST} !^www. [NC]
                    RewriteCond %{HTTP_HOST} ^([a-z0-9]+).domain.com(.*)$ [NC]
                    RewriteRule ^(.*)$ http://www.domain.com/test.php?user=$1$2 [R=301,L]
            </IfModule>
    </IfModule>

这是test.php代码

and this is the test.php code

<?php echo $_GET['user']; ?>

有人知道这里的问题吗?支持对我没有帮助.我认为服务器配置有问题.

does anyone know what the issue here is? the support was not helpful to me. i think there is something wrong with the server configuration.

推荐答案

RewriteCond向后引用使用百分比，而不是美元符号！ ％1而不是$ 1.

RewriteCond backreferences use a percent, not dollar sign! %1 not $1.

RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+).domain.com(.*)$ [NC]
                          ^ %1                  ^ %2
RewriteRule ^(.*)$ http://www.domain.com/test.php?user=$1$2 [R=301,L]
             ^$1                                       ^^^^ oops

$1表示从左侧的正则表达式中提取内容； ％1表示将其从RewriteCond中拉出.假设重写者不会因为$2是一个悬而未决的反向引用这一事实而感到沮丧，那么您可能会将整个比赛作为用户部分坚持下去.

$1 means pull something from the regex on the left; %1 means pull it from the RewriteCond. You may be sticking the whole match as the user part, assuming the rewriter doesn't choke on the fact that $2 is a dangling backreference.
