htaccess和minus在网址中不起作用

Question

当网址为www.xxx.com/theproblem/is-here.html时。我希望得到is-here.html，但有了这条规则......

RewriteRule ^([a-z\-\_A-Z0-9]+)/([^/]+)?(?<!\.html)\b/?(([^/]+)\.html)?$ this.php?param1=$1&param2=$2&param3=$3

... param3的返回值为here.html。那是因为参数2得到is-。

为什么会这样？

我想实现这个目标：

www.xxx.com/theproblem/is-here.html. -> param1=theproblem | param2=is-here.html
www.xxx.com/theproblem/why-this/ -> param1=theproblem | param2=why-this
www.xxx.com/theproblem/why-this/is-here.html. -> param1=theproblem | param2=why-this | param3=is-here.html

我该怎么做？

试试这段代码。这可能不是你想要的（在正则表达式的层面上），但这是有效的：

RewriteEngine On
RewriteRule ^([^/]+)/([^/]+)/([^.].html)$ this.php?param1=$1&param2=$2&param3=$3 [L]
RewriteRule ^([^/]+)/([^/]+)/$ this.php?param1=$1&param2=$2 [L]
RewriteRule ^([^/]+)/([^.].html)$ this.php?param1=$1&param2=$2 [L]
