删除域后的斜杠 [英] Remove trailing slash after domain
问题描述
这是我的 .htaccess
文件:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# Remove multiple slashes anywhere in URL
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
# Never use www prefix!
RewriteCond %{HTTP_HOST} ^www.domain\.org [NC]
RewriteRule (.*) http://domain.org/$1 [R=301,L]
# Remove multiple slashes after domain
RewriteRule ^/(.*)$ http://domain.org/$1 [R=301,L]
# Remove trailing slash in some cases
RewriteRule ^(.*)\.css/$ http://domain.org/$1.css [L,R=301]
RewriteRule ^(.*)\.js/$ http://domain.org/$1.js [L,R=301]
RewriteRule ^(.*)\.jpg/$ http://domain.org/$1.jpg [L,R=301]
RewriteRule ^(.*)\.jpeg/$ http://domain.org/$1.jpeg [L,R=301]
RewriteRule ^(.*)\.png/$ http://domain.org/$1.png [L,R=301]
RewriteRule ^(.*)\.gif/$ http://domain.org/$1.gif [L,R=301]
RewriteRule ^(.*)\.xml/$ http://domain.org/$1.xml [L,R=301]
# Force trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{REQUEST_URI} !(.*)\.css
RewriteCond %{REQUEST_URI} !(.*)\.js
RewriteCond %{REQUEST_URI} !(.*)\.jpg
RewriteCond %{REQUEST_URI} !(.*)\.jpeg
RewriteCond %{REQUEST_URI} !(.*)\.png
RewriteCond %{REQUEST_URI} !(.*)\.gif
RewriteCond %{REQUEST_URI} !(.*)\.xml
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://mydomain.org/$1/ [L,R=301]
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>
但是,当我转到 **/////
时,尾部斜杠不会消失.我做错了什么?
But, when I go to **/////
, the trailing slashes will not go away. What am I doing wrong?
推荐答案
%{REQUEST_URI} 变量在准备好时会减少额外的斜线.所以条件 RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
永远不会匹配,因为对于像 http://domain.org////<这样的请求/strong>,REQUEST_URI 变量减少为 /.尝试使用 THE_REQUEST 变量:
The %{REQUEST_URI} variable gets reduced of extra slashes when it gets prepped. So the condition RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
will never match because for a request like http://domain.org////, the REQUEST_URI variable gets reduced to just /. Try using the THE_REQUEST variable:
RewriteCond %{THE_REQUEST} ^([A-Z]{3,9})\ (.*)//([^\ ]*)
RewriteRule ^ %2/%3 [R=301,L]
此外,当重写规则位于 htaccess 文件中时,前缀(前导斜杠)会从请求 URI 中删除,因此规则 RewriteRule .%1/%2 [R=301,L]
永远不会匹配,因为正则表达式 . 要求至少匹配一个字符.当 URI 为 / 并且前导斜杠被去除时,用于在 url 中匹配的 URI 是一个空字符串.因此,需要使用 ^ 或 (.*) 或等效于一切都包括在内"的正则表达式.
Additionally, the prefix (the leading slash) gets stripped off of the request URI when rewrite rules are in an htaccess file, so the rule RewriteRule . %1/%2 [R=301,L]
would never match because the regex . requires at least one character to match. When the URI is / and the leading slash gets stripped, the URI that's used to match in the url is a blank string. So using ^, or (.*), or something equivalent of "everything including nothing" regex needs to be used.
