如何使用 htaccess 将非 www 重定向到 www URL? [英] How to redirect non-www to www URL's using htaccess?

问题描述

我有一个网站，在我的网站根目录中显示 http://www.example.com/，我添加了 .htaccess 文件以将 http://example.com/ 的任何请求重定向到 http://www.example.com/

I have a website say http://www.example.com/ in the root of my website, I have added .htaccess file to redirect any request of http://example.com/ to http://www.example.com/

最近我创建了一个新的视频"部分，所以视频的 URL 是 http://www.example.com/videos/ .在这个视频文件夹中，我有另一个 htaccess 文件，它正在为视频条目执行重写.当我尝试访问 http://example.com/videos/ 时，它不会将我重定向到 http://www.example.com/videos/

Recently I have created a new section "Videos" so the URL for videos is http://www.example.com/videos/ . In this video folder I have another htaccess file which is performing rewriting for video entries. When I am trying to access http://example.com/videos/ then its not redirecting me to http://www.example.com/videos/

我认为 .htacces 没有从父目录继承以前的规则.谁能告诉我可以在/videos/文件夹的 .htaccess 文件中添加什么规则，以便对 的任何请求http://example.com/videos/ 将被重定向到 http://www.example.com/videos/ 网址.

I think .htacces is not inheriting the previous rules from the parent directory. Can anyone please tell me what can be the rule I can add in the .htaccess file of /videos/ folder so that any request for http://example.com/videos/ will be redirected to http://www.example.com/videos/ URL.

推荐答案

这是一个更通用的解决方案，因为它可以与任何域名一起使用，而无需在每个 .htaccess 中指定特定的域名:

This is a more generic solution, because it can be used with any domain name without having to specify the specific domain name in each .htaccess:

# Redirect non-www to www:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

相反的情况也是可能的(www 到非 www):

The contrary is also possible (www to non-www):

# Redirect www to non-www
RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
