我有一个有趣的重写规则，我不知道做正规EX pression。

I have an interesting RewriteRule and I am not sure to make the regular expression.

总之，我想检查后的URL中的第二个/ - 基于内容的，可能是前进

In short I would like to examine the URL after the second / - based on the contents, possibly forward.

它归纳到这两个规则：

下面举例说明：

http://www.mysite.org/section/subsection/2011 （ OK，什么都不做）

http://www.mysite.org/section/subsection/2011 (OK, do nothing)

http://www.mysite.org/section/subsection/2011-11 （好吧，什么都不做）

http://www.mysite.org/section/subsection/2011-11 (OK, do nothing)

http://www.mysite.org/section/subsection/2011- 11-09 （也不行，重定向）

http://www.mysite.org/section/subsection/2011- 11-W1 （也不行，重定向）

请帮我重写规则和重写电导率

推荐答案

我基于以下的正则表达式掉你的例子这似乎一切都进行分析后，最后一个'/'，而不是第二。

I based the following regex off of your examples which seemed to analyze everything after the last '/' instead of the second.

/[^A-Za-z]{1,7}$

在简单的英语，这正则表达式匹配一组字符遵循一个/，其中包含1-7非字母字符。使它只匹配最后'/'我所附一个'$'，其中行的末尾匹配。

In plain English, this regex matches a group of characters that follows a '/' and contains 1-7 non-alphabetical characters. To make it only match the last '/' I appended a '$', which matches the end of a line.

此外，由于你正在处理的URL，你可能要加上/？在$的情况下，之前有一个悬空'/'结尾。

Also, since you are dealing with URLs you might want to add "/?" before the '$' in case there is a dangling '/' at the end.

/[^A-Za-z]{1,7}/?$

我希望这回答了你的问题。
