Answer 1

我会尝试以下方法：

RewriteEngine On 

# URL with www rewrite to https without www 
RewriteCond %{HTTP_HOST} ^(www\.)(.*) [NC] 
RewriteRule (.*) https://%2%{REQUEST_URI} [L,R=301] 

# URL without www rewrite to https 
RewriteCond %{HTTPS} off 
RewriteCond %{HTTP_HOST} !^(www\.)(.*) [NC] 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
