同一公共目录下CI4与WordPress的HTACCESS重定向循环问题求助

我在同一根目录部署了CodeIgniter 4（CI4）和WordPress程序，当将WordPress的固定链接设置为非默认格式时，会触发重定向次数过多错误。尝试添加规则排除WordPress目录但未解决问题，以下是相关信息及解决方案：

当前CI4的.htaccess代码 #

Options +FollowSymlinks RewriteEngine On
# If you installed CodeIgniter in a subfolder, you will need to
# change the following line to match the subfolder you need.
# http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritebase
RewriteBase /

 #RewriteRule ^(WP)($|/) - [L]
# Redirect Trailing Slashes...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Rewrite "www.example.com -> example.com"
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to the front controller, index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\s\S]*)$ index.php/$1 [L,NC,QSA]

# Ensure Authorization header is passed along
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

尝试过但无效的规则 #

RewriteRule ^(wordpress)($|/) - [L]

解决方案 #

问题根源是CI4的.htaccess规则会拦截WordPress的请求并转发到自身的index.php，导致循环重定向。需要将排除WordPress目录的规则放在CI4所有规则的最顶部，确保优先匹配放行：

修改后的CI4 .htaccess代码：

Options +FollowSymlinks 
RewriteEngine On

# 优先放行WordPress目录的所有请求
RewriteRule ^wordpress($|/) - [L]

RewriteBase /

# Redirect Trailing Slashes...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Rewrite "www.example.com -> example.com"
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to the front controller, index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\s\S]*)$ index.php/$1 [L,NC,QSA]

# Ensure Authorization header is passed along
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

注意事项 #

• 如果你的WordPress不是放在wordpress子目录，需将规则中的wordpress替换为实际目录名称
• 确保WordPress目录下的.htaccess是其固定链接生成的默认规则（比如选择"文章名称"时自动生成的规则）
