我开始涉足CodeIgniter4。完成了一个简单的应用程序。在本地，我将documentroot设置为/public/，而在产品托管环境中，我无法将documentroot设为/public。
相反，它在/root中。
所以结构是这样的：
/root
../admin
../app
../system
../public
../.htaccess
../index.php
我已经将htaccess从公用文件夹移到了根级别。
# Disable directory browsing

# ----------------------------------------------------------------------

# ----------------------------------------------------------------------
# Turning on the rewrite engine is necessary for the following rules and features.
# FollowSymLinks must be enabled for this to work.

# Redirect Trailing Slashes...

什么时候去http://sub.domain.com，我得到了默认的控制器和视图渲染。但是，链接的CSS资产和JS资产：https://sub.domain.com/assets/css/style.bundle.css
都会出现服务器错误。这些文件的位置实际上在https://sub.domain.com/public/assets/css/style.bundle.css
但我尽量避免在url中使用/public/。
感谢任何帮助或指导。
RD
理想情况下，您应该将所有文件夹与根文件夹放在同一级别。这是假设/root是可公开访问的目录。
换句话说，
/admin
/app
/root
.htaccess
favicon.ico
index.php
robots.txt
/assets
/system
/vendor
/writable
请注意，没有名为"public"的目录。事实上，它以前被称为public，但现在已经改名为"root"。没有要求将其命名为public，只要求它是域名指向的目录。
除了在app\config 中设置一些内容外，您应该能够使用分布式的所有文件
