如何修改URL路径匹配正则表达式以排除特定格式URL

Let's break down how to modify your existing regex to exclude the unwanted URLs while keeping the valid matches intact.

Original Regex Recap #

Your original pattern matches URLs with regional segments, a post name, and an optional reviews section (including empty reviews paths):

listing/(.+?)/([^\/.]+)/?(reviews/?(.+?)?/?)?/?$

Key Changes Needed #

We need to address two exclusion cases:

• URLs ending with /reviews/ (empty reviews section)
• URLs containing /add-review/

Modified Regex #

Here's the updated pattern that handles both exclusions:

listing/(.+?)/([^\/.]+)/(?!add-review/)(?:reviews/(.+?)/?)?/?$

Breakdown of Modifications #

1. Negative Lookahead for add-review/:
   The (?!add-review/) part is a negative lookahead that checks immediately after the post name's trailing slash. If the next segment is add-review/, the regex will reject the entire URL, directly excluding those unwanted paths.

2. Enforce Non-Empty Reviews Section:
   We adjusted the reviews segment from reviews/?(.+?)?/? to reviews/(.+?)/? (wrapped in a non-capturing group (?:...)). This ensures that if a reviews/ segment exists, it must be followed by at least one character (no empty reviews paths allowed).

Test Cases #

• Still Matches:
  • listing/united-states/postname1/
  • listing/united-states/california/postname2/
  • listing/united-states/california/chino/postname3/
  • listing/united-states/california/chino/postname4/reviews/testreview/
• No Longer Matches:
  • listing/united-states/california/chino/postname1/reviews/
  • listing/united-states/california/chino/postname2/add-review/
