我看到.htaccess Redirect non-WWW to WWW preserving URI string但它对我不起作用
如果我去 mysite.com/site/something ,我会被重定向到 mysite.com/something
RewriteCond %{HTTP_HOST} !^www\.mysite\.com$
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
也尝试过:
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www.mysite.com [NC]
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
修改
这是我使用的代码,基于Alfonso Rubalcava的回答:
if (substr($_SERVER['SERVER_NAME'], 0, 3) != 'www')
{
if ($_SERVER['REQUEST_URI'] == '//site/')
{
header('HTTP/1.1 301 Moved Permanently');
header('Location: http://www.site.com/site/');
exit;
}
header('HTTP/1.1 301 Moved Permanently');
header('Location: http://www.site.com' . $_SERVER['REQUEST_URI']);
exit;
}

在index.php中尝试开头:
if(substr($_SERVER['SERVER_NAME'],0,3)=="www"){
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://yourdomain.tdl/".$_SERVER['REQUEST_URI']);
}else{
//the current contents of your file
}
修改强> 我读错了你的问题,答案是:
if(substr($_SERVER['SERVER_NAME'],0,3)!="www"){
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.yourdomain.tdl/".$_SERVER['REQUEST_URI']);
}else{
//the current contents of your file
}

在codeigniter的.htaccess文件中包含这两行,将非www url重定向到www
RewriteCond %{HTTP_HOST} !^www\.(.*)
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]
即完整的.htaccess文件将是这样的 - >
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.(.*)
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

使用此代码
#Redirect to www
RewriteEngine On
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

我知道,这个问题已经有了公认的解决方案。但是,如果域中还包含一些子域,则会出现问题。如果您的codeigniter也可以处理子域,则这些子域也将重定向到www。
在这种情况下,这就是答案。假设您的域名为www.thedomain.com,代码应为:
$sna = explode(".", $_SERVER['SERVER_NAME']);
if($sna[0]=="thedomain"){
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.thedomain.com/".$_SERVER['REQUEST_URI']);
}

您可以在所有codeigniter网站中使用以下代码。
`
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.(.*)
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
