在WordPress主站子目录部署Laravel站点遇404问题求助

站点结构 #

• 主站根目录（public_html）部署WordPress
• Laravel文件存放于主站根目录的laravelfiles子目录，对外访问入口为laravelfiles/public

现有配置文件内容 #

主站根目录（public_html）的.htaccess #

<IfModule security2_module>
    SecRuleRemoveByTag unoeuro
</IfModule>

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Laravel的public目录（public_html/laravelfiles/public）的.htaccess #

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes
    </IfModule>

    RewriteEngine On

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Send Requests To Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

Laravel的public/index.php代码 #

require __DIR__.'/../vendor/autoload.php';
$app = require_once __DIR__.'/../bootstrap/app.php';

Laravel的.env配置 #

APP_URL='https://mainsite/laravelfiles'
FRONTEND_URL='https://mainsite/laravelfiles/public'

问题描述 #

完成上述配置后，访问Laravel站点时始终显示"页面未找到"错误。已尝试修改.htaccess、.env、index.php文件，清除Laravel缓存等多种常见解决方案，但问题仍未解决。
