将非 www 域重定向到 www 域而不影响子域

Question

@Starkeen，此代码对我不起作用。现在所有其他页面都有 404 错误，并且主页没有添加 www。

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^sitename.com$
RewriteRule ^(.*)$ http://www.sitename.com/$1 [NC,R=301,L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#This last condition enables access to the images and css folders, and the robots.txt file
RewriteCond $1 !^(index\.php|public|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [R=301,L]
</IfModule>

请帮忙

Answer 1

在“RewriteEngine on”指令之后将其添加到您的 htaccess 文件中

RewriteCond %{HTTP_HOST} ^domain.com$
RewriteRule ^(.*)$ http://www.domain.com/$1 [NC,R=301]

编辑

在第一次重写中添加了缺少的 L 标志

试试这个：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com$
RewriteRule ^(.*)$ http://www.domain.com/$1 [NC,R=301,L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#This last condition enables access to the images and css folders, and the robots.txt file
RewriteCond $1 !^(index\.php|public|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [NC,R=301,L]
</IfModule>
