.htaccess Redirect non-WWW to WWW preserving URI string
提问by Steven
I'm running the CodeIgniter platform, which uses .htaccess to accept URLs like
我正在运行 CodeIgniter 平台，它使用 .htaccess 来接受像
http://www.mysite.com/controller/function/argument
I currently use some .htaccess rewrites, namely (simplified):
我目前使用一些 .htaccess 重写，即（简化）：
RewriteEngine On
RewriteCond %{REQUEST_URI} !^(/index\.php|/images|/assets)
RewriteRule ^(.*)$ /index.php/ [L]
I want to add a rewrite rule that redirects all non www requests to www. I also want the URI string following the domain name to stay the same in the redirect. For instance, if a user makes a request for http://mysite.com/controller/function/argument, I want the .htaccess file to rewrite the request in the browser as http://www.mysite.com/controller/function/argumentand then process the request.
我想添加一个重写规则，将所有非 www 请求重定向到 www。我还希望域名后面的 URI 字符串在重定向中保持不变。例如，如果用户发出请求http://mysite.com/controller/function/argument，我希望 .htaccess 文件在浏览器中重写请求http://www.mysite.com/controller/function/argument，然后处理请求。

I had a similar problem, and this .htaccess works for me
我有一个类似的问题，这个 .htaccess 对我有用
RewriteEngine On
#This bit rewrites your host name to include www
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/ [R=301,NC,L]
#This bit does the codeigniter magic
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/ [L]

It should be something like this:
它应该是这样的：
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule (.*) http://www.example.com/ [R=301,L]

If you are on apache 2.4 ,You can use the following simple redirect :
如果您使用的是 apache 2.4，则可以使用以下简单重定向：
<if "%{HTTP_HOST} =='example.com'">
Redirect / http://www.example.com/
</if>
