如何将https://www.example.com重定向到https://example.com [英] How to redirect https://www.example.com to https://example.com

问题描述

我环顾四周，但似乎无法找到确定的解决方案.我们的域名访问者中有少数人或我们的访问者有一个小问题:

I have looked around and I can't seem to find a definitive solution for this. We are having a small problem with a few or our visitors that are typing in our domain as such:

https://www.example.com-这是一个安全警告此网站的安全证书有问题."

https://www.example.com - This is giving a security warning "There is a problem with this website's security certificate."

我们为example.com

因此，如果有人输入http://www.example.com或www.example.com，它将被重定向到https://example.com，这很好用.

So if someone types in http://www.example.com or www.example.com this gets redirected to https://example.com which works fine.

这是我目前在.htaccess文件中拥有的内容:

This is what I have currently have in my .htaccess file:

Options +FollowSymLinks 
RewriteEngine on
RewriteCond %{SERVER_PORT} 80
RewriteCond %{SERVER_PORT} !^443$ [OR]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,NC,L]

推荐答案

大多数SSL证书是针对特定主机名颁发的，例如www.example.com或example.com(*.example.com也可能有通配符证书)，因此可能是这种情况.

Most SSL certificates are issued for a specific hostname, e.g. www.example.com or just example.com (and there can be wildcard certificates for *.example.com too) so this might be the case.

也许在最后一个RewriteCond中将 www.子域作为可选匹配可能有助于使用户进入证书中所述的域:

Maybe making the www. subdomain an optional match in the last RewriteCond might help to get the user to the domain stated in the certificate:

RewriteCond %{HTTP_HOST} ^(?:www\.)?(.*) [NC]
