删除多个尾部斜杠 mod_rewrite [英] remove multiple trailing slashes mod_rewrite
问题描述
我知道仅在这个网站上就有人多次问过这个问题,但浏览相关帖子我找不到解决方案.尝试在域后删除多个尾部斜杠.以下 mod_rewrite 表达式似乎适用于诸如 http://www 之类的 URL.domain.com//path1//path2////,但不适用于域//
I know this question was asked a number of times on this site alone, but browsing through the relevant posts I couldn't find a solution. Trying to remove multiple trailing slashes after domain. The following mod_rewrite expressions seem to work for URLs such as http://www.domain.com//path1///path2////, but do not work for domain//
DirectorySlash Off
RewriteEngine on
# Canonical fix
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301]
RewriteRule ^/main.do http://www.domain.com/ [R=301,L]
RewriteRule ^/index.jsp http://www.domain.com/ [R=301,L]
# Remove bogus query strings
RewriteCond %{query_string} q= [NC]
RewriteRule (.*) http://www.domain.com/$1? [R=301,L]
# Remove multiple slashes after domain - DOESN'T WORK!!!
#RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
#RewriteCond %{REQUEST_URI} ^(.*/)/+$
#RewriteRule / http://www.domain.com/%1 [R=301,L]
# Remove multiple slashes anywhere in URL
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
# Externally redirect to get rid of trailing slash except for home page, ads
RewriteCond %{REQUEST_URI} !^/ads/
RewriteRule ^(.+)/$ $1 [R=301,L]
推荐答案
无法重现.即使关闭了 DirectorySlashes,域之后的额外斜杠也不会立即传递给 mod_rewrite——我还没有检查是 Opera 还是 Apache 删除了斜杠).但除此之外,一切正常:
Can't reproduce. Extra slashes immediately after the domain are never passed to mod_rewrite even with DirectorySlashes off -- I haven't checked whether it's Opera or Apache that's removing the slash). But otherwise, everything works fine:
RewriteBase /
RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
RewriteCond %{REQUEST_URI} ^(.*/)/+$
RewriteRule .* http://domain/%1 [R=301,L]

注意:不要对主机进行硬编码:
Note: consider not hard-coding the host:
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{REQUEST_URI} ^//+(.*)$ [OR]
RewriteCond %{REQUEST_URI} ^(.*/)/+$
RewriteRule .* http://%{HTTP_HOST}/%1 [R=301,L]
还要注意内部的//"没有被替换.您将添加另一条规则来替换内斜线.
Also note that the inner "//" was not replaced. You will to add another rule to replace inner slashes.
新好的,这似乎可以防止 URL 以//:
NEW OK, this seems to work for preventing URLs starting or ending with //:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{THE_REQUEST} ^[A-Z]+s//+(.*)sHTTP/[0-9.]+$ [OR]
RewriteCond %{THE_REQUEST} ^[A-Z]+s(.*/)/+sHTTP/[0-9.]+$
RewriteRule .* http://%{HTTP_HOST}/%1 [R=301,L]
