通配符.htaccess并拒绝子域上的某些地址

标签: regex apache .htaccess mod-rewrite redirect

我希望up.example.com子域名下的所有文件或目录都被拒绝,并显示404错误。

此外,我希望所有其他请求指向index.php

我写这段代码:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^up\.(.+)$ [NC]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*)$ - [R=404,L,NS]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L,QSA]

当我为http://up.example.com/test.jpg

测试此代码时

如果根服务器上存在test.jpg文件,请显示以下错误:

Not Found
The requested URL /test.jpg was not found on this server.
Apache Server at up.example.com Port 80

没关系!
但是当test.jpg不存在时,请给我这个错误:

Not Found
The requested URL /index.php was not found on this server.
Apache Server at up.example.com Port 80

而是打开index.phpindex.php存在于root上)

为什么呢?我该如何解决?

试试这个

RewriteEngine On

RewriteCond %{HTTP_HOST} ^up\.(.+)$ [NC]  # remove if it is not related to subdomain
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L,QSA]

RewriteCond %{HTTP_HOST} ^up\.(.+)$ [NC]
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteRule ^(.*)$ - [R=404,L,NS]

实际上问题是您将所有内容写入index.php并且该请求成为有效文件。当mod_rewrite下次运行时,第一个规则会将其发送到404。

要克服此错误,请遵守以下规则:

RewriteEngine On

# if it is valid file or directory except for index.php
# then send 404 to browser
RewriteCond %{HTTP_HOST} ^up\. [NC]
RewriteCond %{THE_REQUEST} \s/+index\.php[?\s] [NC]
RewriteRule ^index\.php$ - [R=404,L,NC]

RewriteCond %{HTTP_HOST} ^up\. [NC]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule !^index\.php$ - [R=404,L,NC]

# send all non-file/directories to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
