将http重定向到https，将www重定向到非www？

Question

I searched in Google for this and checked over 50 posts but none seems to work. Lets assume that I have a domain example.com. What I want to do is redirect

http://www.example.com
https://www.example.com
http://example.com

to

https://example.com

Can anybody please help me?? Any help would be appriciated.

Note: I'm using cloudflare and I don't have access to conf file. I have access to .htaccess files.

EDIT1 :My htaccess looks like

RewriteEngine On 
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.*)$ [NC]
RewriteRule (.*) https://%1%{REQUEST_URI} [L,R=301]

Answer 1

You can try something like this:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,R=301,NE]

Answer 2

You can use this rule in Cloudfare:

RewriteEngine On 

RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"' [OR]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,R=301,NE]
