使用 htaccess 停止子域的 WWW

Question

我的subdomain.example.com重定向到www.subdomain.example.com 。

訪問代碼：

# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

### END WWW & HTTPS

我在尋找

example.com至www.example.com

anything.example.com到anything.example.com

我怎樣才能解決這個問題？

更新：我對子域和根域都使用一個 htaccess 文件，出於某種原因，我不能為不同的域使用單獨的 htaccess 文件。

注意：請不要將此問題標記為重復。 我已經搜索了 stackoverflow 的其他部分，但沒有找到可行的解決方案。

Answer 1

您需要限制重寫條件以僅匹配頂級域：

# ensure www. to top level domain only
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

### END WWW & HTTPS

確保在測試前清除瀏覽器緩存。

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
