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

要将http://或https://重定向到https://www,您可以在所有版本的apache上使用以下规则:

RewriteEngine on

RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,L,R]

Apache 2.4

RewriteEngine on

RewriteCond %{REQUEST_SCHEME} http [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,L,R]

注意,%{REQUEST_SCHEME}变量从apache 2.4开始就可以使用了。

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

在你的。htaccess文件中设置

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

如果你使用CloudFlare,请确保你使用这样的东西。

# BEGIN SSL Redirect
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END SSL Redirect

这将使您免于重定向循环,并将您的站点安全地重定向到SSL。
