use htaccess to add www with https support
提问by quinn
There are a lot of code examples for using .htaccess to add www to a url but they are usually confined to using http. does anybody have an example of how to get it to work in both cases?
有很多使用 .htaccess 将 www 添加到 url 的代码示例，但它们通常仅限于使用 http。有没有人有如何让它在这两种情况下工作的例子？

Sure:
当然：
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
The second condition checks if the HTTPSenvironment variable (either onor off) is set to onand captures the appended sthat is then available with %1. If it doesn't match, %1is just an empty string.
第二个条件检查HTTPS环境变量（on或off）是否设置为on并捕获s随后可用的附加%1。如果不匹配，%1则只是一个空字符串。

use this code in .htaccess and it will add both https and www
在 .htaccess 中使用此代码，它将同时添加 https 和 www
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
