爲什麼這個簡單的重寫降到500服務器錯誤？

Question

我有自己的沙盒/測試系統，我想重寫g/something到g/something.php

我用這個很容易重寫規則

RewriteEngine on 
RewriteRule ^g/(.*?)[^\.]+ g/$1.php [L] 

問題：

• 我怎麼能否定我的規則？ （這意味着，當請求的文件不與.php結束此規則纔會觸發。我已經試過(^\.php)，(!\.php)但是毫無效果，所以我用[^\.]。
• 爲什麼這條線拋出500內部服務器錯誤？

Answer 1

^g/(.*?)[^\.]+ 

您更換相匹配，因爲它是如g/test.php這是g/，然後test.ph，然後p，其中不包括.。所以替換被重新替換，等等。結果，重定向溢出（查看Apache錯誤日誌）。

你可能想：

^g/([^.]*?)$ 

因爲匹配g/，那麼沒有點任何東西，然後的URL結束，以確保它的確切URL匹配。
