使用path_reg匹配haproxy路径 [英] Match haproxy path using path_reg

问题描述

我正在尝试将以下网址匹配:/rivers/1，/rivers/2adsfs，/rivers/sdfd2d与

I'm trying to match urls like: /rivers/1, /rivers/2adsfs, /rivers/sdfd2d with:

  acl rivers_show   path_reg ^/rivers/\w+/?

但这似乎确实有效.有人知道为什么吗?

But that does seem to work. Anyone know why?

推荐答案

HAproxy的正则表达式不包含\ w作为字符类.请记住，正则表达式是性能最差的ACL匹配之一.您可能想研究使用类似这样的东西，尽管它并不完全相同.

HAproxy's regex does not include \w as a character class. Keep in mind regex is one of the worst performing ACL matches. You may want to look into use something like this instead, although its its not exactly the same.

acl path_beg/rivers/

acl path_beg /rivers/
