WordPress网站.htaccess配置疑问：规则位置与标签使用

1. 为何重定向命令放在WordPress基础规则后无法正常运行？ #

Apache的Rewrite规则是从上到下按顺序执行的，而WordPress核心规则里包含带[L]标志的规则：

RewriteRule ^index\.php$ - [L]
RewriteRule . /index.php [L]

[L]标志的作用是终止当前一轮的规则处理，一旦匹配到这些规则，后续的所有Rewrite规则（包括你的重定向规则）都会被跳过，根本没机会执行。

另外，当请求先经过WordPress规则时，非文件/目录的请求会被直接转发到index.php，此时就算你的重定向条件（比如www域名或HTTP协议）满足，也不会触发重定向——因为规则执行已经被[L]终止了。

2. 将WordPress基础规则放在第三位是否存在问题？ #

当前的顺序（重定向→WordPress核心→缓存/处理器规则）是完全合理且推荐的：

• 重定向是前置的标准化操作，必须先把所有请求统一到非www + HTTPS的规范地址，避免出现重复内容（SEO大忌），同时确保后续的WordPress、缓存规则都是基于正确的地址生效。
• 重定向完成后，浏览器会发起新的请求，此时WordPress规则就能正常处理规范地址的请求，不会影响网站的正常运行。

只要重定向规则保持在最前面，WordPress规则放在第三位没有任何问题。

3. 重复使用是否有必要？ #

完全没必要重复添加。
<IfModule rewrite_module>的作用是判断mod_rewrite模块是否启用，只要在所有Rewrite规则的最外层添加一次就足够覆盖所有后续的Rewrite规则。重复添加不仅冗余，反而会增加代码复杂度，违背“保持整洁”的初衷。

你可以把前两个重定向块合并到同一个<IfModule rewrite_module>标签内，并且整个.htaccess里只需要写一次RewriteEngine On（因为启用一次就全局生效），优化后的重定向部分可以改成这样：

# BEGIN redirects (www to non-www + HTTP to HTTPS)
<IfModule rewrite_module>
    RewriteEngine On
    # 重定向www到非www
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
    # 重定向HTTP到HTTPS
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END redirects

你的原始.htaccess代码 #

# BEGIN redirect www to non www
<IfModule rewrite_module>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
</IfModule>
# END redirect www to non www

# BEGIN redirect to https
<IfModule rewrite_module>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END redirect to https

# BEGIN WordPress
