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。

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R]

其他回答

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

注意:请确保您已经完成了以下步骤

Sudo a2enmod重写 Sudo服务apache2重启 在vhost文件中添加Following,该文件位于/etc/apache2/sites-available/000-default.conf

<Directory /var/www/html>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride All
  Order allow,deny
  allow from all
  Require all granted
</Directory>

现在你的.htaccess将会 Work和您的网站将重定向到http://到https://www

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R]

糟糕的解决方案,为什么!

永远不要使用下面的解决方案,因为当你使用他们的代码时,它是这样的:

RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.example.com%{REQUEST_URI} [L,R=301]

浏览器进入:

http://example.com

然后重定向到:

https://example.com

然后重定向到:

https://www.example.com

这对服务器来说请求太多了。

大多数答案甚至是公认的都有这个问题。


最好的解决方案和答案

这段代码有一个[OR]条件,以防止url的双重更改!

RewriteEngine on
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule (.*) https://www.example.com%{REQUEST_URI} [R=301,L]

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
