Apache从非WWW重定向到WWW

我有一个网站，似乎不能从非www重定向到www。

我的Apache配置如下:

RewriteEngine On
### re-direct to www
RewriteCond %{http_host} !^www.example.com [nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]

我错过了什么?

这是我自己网站的配置，工作起来很有魅力。

<IfModule mod_ssl.c>
  <VirtualHost *:443>
    ServerAdmin admin@domain.com

    ServerName www.domain.com
    ServerAlias domain.com

    DocumentRoot /var/www/html/domain

    <Directory /var/www/html/domain/>
      Options FollowSymLinks
      AllowOverride All
      Require all granted
    </Directory>

    # Redirect non-www to www
    RewriteEngine On

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

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/domain.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/domain.com/privkey.pem
  </VirtualHost>
</IfModule>

我使用的代码是:

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

RewriteCond %{HTTP_HOST} ^!example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

This starts with the HTTP_HOST variable, which contains just the domain name portion of the incoming URL (example.com). Assuming the domain name does not contain a www. and matches your domain name exactly, then the RewriteRule comes into play. The pattern ^(.*)$ will match everything in the REQUEST_URI, which is the resource requested in the HTTP request (foo/blah/index.html). It stores this in a back reference, which is then used to rewrite the URL with the new domain name (one that starts with www).

[NC]表示不区分大小写的模式匹配，[R=301]表示使用代码301进行外部重定向(资源永久移动)，[L]停止所有进一步重写，并立即重定向。

要将所有直接发送到域名www的请求重定向到301，您可以使用:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^([^.]+\.[^.]+){2,}$ [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

这样做的好处是，如果你有任何有效的子域，这将工作。

example.com重定向到www.example.com

没有重定向

这对我来说很管用:

RewriteCond %{HTTP_HOST} ^(?!www.domain.com).*$ [NC]
RewriteRule ^(.*)$  http://www.domain.com$1  [R=301,L]

在将所有域重定向到www子域时，我使用前瞻性模式(?!www.domain.com)来排除www子域，以避免Apache中的无限重定向循环。

http://example.com/subdir/?lold=13666 => http://www.example.com/subdir/?lold=13666

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