我有以下htaccess代码:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond !{HTTPS} off
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
我希望我的网站被重定向到https://www。使用HTTPS，并强制执行www。子域名, 但当我访问http://www时。(没有HTTPS)，它不会重定向到https://www与HTTPS。
当前回答
要首先强制使用HTTPS，您必须检查正确的环境变量%{HTTPS} off，但是上面的规则将www。因为你有第二条规则来执行www.，所以不要在第一条规则中使用它。
RewriteEngine On
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
# [NC] is a case-insensitive match
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
关于代理
在某些形式的代理背后，客户端通过HTTPS连接到代理、负载均衡器、Passenger应用程序等，%{HTTPS}变量可能永远不会打开，并导致重写循环。这是因为即使客户端和代理/负载均衡器使用的是HTTPS，应用程序实际上接收的是纯HTTP流量。在这些情况下，检查X-Forwarded-Proto报头，而不是%{HTTPS}变量。这个答案显示了适当的过程
其他回答
这是我为代理用户和非代理用户找到的最好的方法
RewriteEngine On
### START WWW & HTTPS
# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
### END WWW & HTTPS
我试着第一个回答，它不工作… 这项工作:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{ENV:HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R]
如果您正在使用CloudFlare或类似的CDN，您将得到一个无限循环错误的%{HTTPS}解决方案提供在这里。如果你是CloudFlare用户，你需要使用这个:
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
有很多解决方案。这里有一个apache wiki的链接，它直接处理了这个问题。
http://wiki.apache.org/httpd/RewriteHTTPToHTTPS
RewriteEngine On
# This will enable the Rewrite capabilities
RewriteCond %{HTTPS} !=on
# This checks to make sure the connection is not already HTTPS
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
# This rule will redirect users from their original location, to the same location but using HTTPS.
# i.e. http://www.example.com/foo/ to https://www.example.com/foo/
# The leading slash is made optional so that this will work either in httpd.conf
# or .htaccess context
