如何使用.HTACCESS文件从public目录提供PHP页面而不在URL中显示public？
我的.HTACCESS文件中包含的内容：
RewriteEngine on
RewriteCond $1 !^bower_components($|/)
RewriteCond $1 !^node_modules($|/)
RewriteRule ^(.*)$ public/$1 [L]
我的项目文件系统包含的内容：
.htaccess
bower_components/
node_modules/
public/
a/
index.php
some_other_page.php
b/
c/
src/ <------ should NOT be accessible to public
网址
http://example.com/something/a/
http://example.com/something/a/index.php
http://example.com/something/a/some_other_page.php
http://example.com/something/b/
等等。
上述.HTACCESS适用于所有情况，除非没有尾部斜杠。
这有效：http://example.com/something/a/
这不起作用：http://example.com/something/a
重定向到http://example.com/something/public/a/并发出404 Not Found错误。
如何使用和不使用尾部斜杠来使其工作？
还按照评论中的建议尝试了DirectorySlash指令的值On和Off，但结果没有改变。
在Apache 2.2.15和Apache 2.4.18上都会发生这种情况。

访问时没有斜杠时记录RewriteLogLevel 3：
