.htaccess重定向https，如果不存在子域，则自动添加www

Question

需要帮助，

对于我在Planethoster托管的网站，我试图将HTTP强制为HTTPS，而不使用www自动使用https://www.

在.htaccess 中使用此代码

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteCond %{HTTP_HOST} ^[^.]+.[^.]+$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301] 

但当我只使用网址mydomain.com而不使用www它返回一个奇怪的url：https://www.mydomain.com/https://mydomain。com/(com之前没有espace(

因此，我无法使用mydomain.com访问我的网站，我必须手动将www

有人能帮我吗？

如果没有其他子域，则强制SSL并要求www。你可以试试这个，

# if ssl is off and starts with www or no subdomain,
# redirect to https://www.
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www.example.com [OR]
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule ^ https://www.example.com%{REQUEST_URI} [L,R=301]
# if ssl and no subdomain, redirect to www.
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule ^ https://www.example.com%{REQUEST_URI} [L,R=301]
# if ssl off, and there's a subdomain that's not www,
# just use the current subdomain but redirect to https
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www.example.com
RewriteCond %{HTTP_HOST} ^(.*).example.com
RewriteRule ^ https://%1.example.com%{REQUEST_URI} [L,R=301]

你可以在这里测试它们，https://htaccess.madewithlove.be

这些应该涵盖所有场景，

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