【问题描述】：

如果文件夹安装存在，我会尝试重定向用户，但到目前为止我没有运气。

下面是我的 htaccess 文件。

RewriteEngine On
RewriteBase /enc/project/
# If the setup directory exists in the document root...
RewriteCond %{DOCUMENT_ROOT}/install -d
# ...and you're not in isntall..
RewriteCond %{REQUEST_URI} !(install) [NC]
# ...redirect to setup - with a 302 (temporary redirect) to make sure the browser won't cache the redirect.
RewriteRule ^(.*) /install [L,redirect=302]
# ...rest of htaccess for codeigniter
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

codeigniter 项目在我服务器的/enc/project/ 中，这就是 RewriteBase 的原因。

Project Structure is

htdocs/enc/project/
|-- application/
|   |-- project
|
|-- system/
|   |-- project
|
|-- install/
|   |-- test/
|   |   |-- test_main.php
|   |   
|   |-- index.php
|
|-- htaccess

localhost/enc/project
我用我的项目结构编辑了这个问题
我现在就试一试，然后告诉你。谢谢
是的，问题出在这个问题上，尽管我得到一个空白页并将我尝试加载的每个 css 请求或文件重定向到安装文件夹

【解决方案1】：

这是一种有效的编写方式：

RewriteEngine On
RewriteBase /enc/project/
# If the setup directory exists in the document root...
RewriteCond %{DOCUMENT_ROOT}/enc/project/install -d
# ...and you're not in isntall..
RewriteCond %{REQUEST_URI} !(install) [NC]
# ...redirect to setup - with a 302 (temporary redirect) to make sure the browser won't cache the redirect.
RewriteRule ^(.*) /enc/project/install/ [L,redirect=302]
# ...rest of htaccess for codeigniter
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

【解决方案2】：

试试这些规则

RewriteEngine On
RewriteBase /enc/project/

# If the setup directory exists in the document root...
RewriteCond %{DOCUMENT_ROOT}/enc/project/install -d
# ...and you're not in isntall..
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# ...redirect to setup - with a 302 (temporary redirect) to make sure the browser won't cache the redirect.
RewriteRule !^install/ install/ [L,NC,R=302]

# ...rest of htaccess for codeigniter
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
