wordpress - 尝试使用 htaccess 重定向站点时出现 "Too many redirects"

Question

我需要使用 301 重定向将我的网站从 example.net 重定向到 www.example.net。

我正在为我的网站使用一体式 WP 安全和防火墙，它会自动在我的 .htaccess 文件中添加其他代码。重定向不起作用，我认为这是由额外的代码引起的。我在浏览器中看到的错误是:

Too many redirects occurred trying to open www.example.net.

All In One WP 安全与防火墙会生成此类错误吗？

我的 301 代码:

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

多合一代码:

Answer 1

问题在于

RewriteRule ^(.*)$ www.example.net/$1 [L,R=301,NC]

www.example.net 被视为相对路径，而不是不同的域。

这就是它将 URL http://example.net/some/path 重写为 http://example.net/www.example.net/some 的原因/path，再次重写为 http://example.net/www.example.net/www.example.net/some/path 等等。

如果您想从域 example.net 重写到域 www.example.net，您必须将协议(protocol) (http) 添加为嗯，例如

RewriteRule ^(.*)$ http://www.example.net/$1 [L,R=301,NC]

批发域名重定向的另一种方法是使用 Redirect指令

Redirect / http://www.example.net

<小时/>

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

使用 %{HTTP_HOST} 具有相同的效果，因为它不包含方案，即 http 或 https。此外，您从 %{HTTP_HOST} 重写为 %{HTTP_HOST}，这不会发生任何变化。

要解决此问题，您必须在替换前添加 www. 以及方案(http 或 https)。这里不需要 NC 标志，因为无论如何您都会查找任何字符 .*。所以规则应该看起来像

RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R]

最后，切勿使用 R=301 进行测试!请参阅此答案 Tips for debugging .htaccess rewrite rules了解详情。
