如何使用htaccess将www和非www重定向到特定域的https(how to redirect www and non www to https for specific domain using htaccess)

 我需要将www和非www重定向到https。 我已经在stackoverflow上到处寻找，但找不到我正在寻找的东西。 
 
 规则是： 
 
 
 
 example.com和www.example.com以及https://example.com必须重定向到https://www.example.com 
 
 
 它必须与域和扩展example.com匹配。 它不能是一张外卡，它也匹配abc.com或123.com或example.net或其他任何东西 
 
 
 它必须仅匹配www子域。 它不能是与sub.example.com或thisisademo.example.com匹配的外卡 
 
 
 我目前有： 
 
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]
 
 但是，如果有人进入www.example.com，它仍会转到http版本而不是https。 
 
 我认为我真正需要的是RewriteCond正则表达式以完全匹配，只有“example.com”和“www.example.com” 
 
 谢谢 

I need to redirect www and non www to https. I have looked everywhere on stackoverflow but can't find quite what I'm looking for.
 
The rules are:
 
 
 
example.com and www.example.com and https://example.com must redirect to https://www.example.com
 
 
It must match the domain and extension example.com. It cannot be a wild card which also matches abc.com or 123.com or example.net or anything else
 
 
It must match for www subdomains only. It cannot be a wild card which also matches sub.example.com or thisisademo.example.com
 
 
I currently have:
 
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]
 
However if someone enters www.example.com it still goes to the http version instead of https.
 
What I think I actually need here is RewriteCond regex to match exactly and only "example.com" and "www.example.com"
 
Thanks
