.htaccess - 如何从 url 中删除重复的字符? [英] .htaccess - how to remove repeated characters from url?

问题描述

我有以下网址:

example.com/hellllllllllo

我一直在寻找一种方法来避免重复字符最多加倍.

And I was looking for a way to avoid repeated characters up to double.

受此问题/答案的启发使用 htaccess 从 URL 中删除字符 我已创建以下 htaccess 文档以避免重复字符.如果字符重复超过 23 次，则 url 没有完全重写，我想知道是否有任何可能的改进?

Inspired by this question/answers Remove Characters from URL with htaccess I have created the following htaccess document to avoid repeated characters. If the character is repeated more than 23 times the url is not completely rewrited and I was wondering if there is any possible improvment?

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*)l{3,}(.*)$
RewriteRule . %1ll%2 [R=301,L]

推荐答案

这是我的完整答案，以避免使用 samurai8 在之前的评论中建议的惰性匹配在 url 中重复字符:

Here is my full answer to avoid repeated characters in urls using lazy match as suggested by samurai8 in previous comments:

用于重复的斜线和破折号

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)(/{2,})(.*)$
RewriteRule . %1/%3 [R=301,L]

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)(-{2,})(.*)$
RewriteRule . %1-%3 [R=301,L]

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)(_{2,})(.*)$
RewriteRule . %1_%3 [R=301,L]

对于单词中的重复字母

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)a{3,}(.*)$
RewriteRule . %1aa%2 [R=301,L]

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)b{3,}(.*)$
RewriteRule . %1bb%2 [R=301,L]

RewriteCond %{REQUEST_METHOD}  !=POST
RewriteCond %{REQUEST_URI} ^(.*?)c{3,}(.*)$
RewriteRule . %1cc%2 [R=301,L]
