为多个域和 SSL 配置 .htaccess

Question

我有一个主域“example.co.uk”和 6 个其他域 + 1 个 IP 地址指向同一个文件夹根目录。

我想将 HTTPS 用于主域，即 https://www.example.co.uk，并将所有其他域重定向到该域的主页（避免 SEO 问题和与 example.com 域和 IP 地址的内容重复）

如何使用我当前的 .htaccess 文件实现这一点？

RewriteEngine on

#Redirect IP address to example.co.uk.
RewriteCond %{HTTP_HOST} ^12\.34\.567\.890
RewriteRule (.*) https://www.example.co.uk/$1 [R=301,L]

# Redirect example.com to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

# Redirect example2.co.uk to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example2\.co\.uk$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

# Redirect example3.co.uk to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example3\.co\.uk$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

# Redirect example4.com to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example4\.com$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

# Redirect example5.co.uk to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example5\.co\.uk$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

# Redirect example6.com to example.co.uk.
RewriteCond %{HTTP_HOST} ^(www\.)?example6\.com$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/$1 [R=301,L]

Answer 1

您可以通过否定对 HTTP HOST 的条件检查来减少规则的数量。然后，您只需要检查 HTTPS 的规则：

RewriteEngine On

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

# redirect all the other domains to the homepage
RewriteCond %{HTTP_HOST} !^www\.example.co.uk$ [NC]
RewriteRule ^(.*)$ https://www.example.co.uk/ [L,R=301]

在您的问题中，您说您想将所有其他域重定向到该域的 主页，但您的规则根本没有这样做。您的规则将请求重定向到同一个请求，但只是这个域。如果要保留该逻辑，则需要在 https://www.example.co.uk/ 的末尾添加 $1。
