使用 htaccess 删除尾随问号 [英] Removing trailing question mark with htaccess
问题描述
有人能帮我理解这段代码吗?
Can someone help me understand this code?
# Remove trailing ?
RewriteCond %{THE_REQUEST} ? HTTP [NC]
RewriteRule .? /%{REQUEST_URI}? [R=301,L]
基本上我有一个网站 www.example.com 生成一个链接到 www.example.com/index.cfm?我需要它重定向到 www.example.com 以进行 SEO 复制.我设法删除了 index.cfm 但 ?仍然留在那里(www.example.com/?).如果结尾的斜杠是最后一个字符，它也会被删除.我在网上找到了这条规则，但我在 apache 中收到了RewriteCond: bad flag delimiters"警报，但它没有做任何事情.
Basically I have a site www.example.com that is generating a link to www.example.com/index.cfm? I need it to redirect to www.example.com for SEO duplication purposes. I managed to remove the index.cfm but the ? still stays there (www.example.com/?). The trailing slash is also removed just fine if it's the last character. I found this rule online but I'm getting a "RewriteCond: bad flag delimiters" alert in apache and it doesn't do anything.
我也有一些页面，如 www.example.com/index.cfm?term=test 用于搜索，所以我只想去掉尾随的问号，而不是当我有附加查询时.
I also have some pages like www.example.com/index.cfm?term=test for searching so I just want to get rid of the trailing question mark and not when I do have a query attached to it.
错误在 RewriteCond 中.我需要帮助了解这种情况以及为什么它不起作用，而不仅仅是它的答案.
The error is in the RewriteCond. I need help understanding the condition and why it doesnt work not just the answer to it.
以防万一这里是整个 htaccess:
Just in case here is the entire htaccess:
RewriteEngine On
Rewritebase /
# remove trailing index.cfm
RewriteRule ^index.cfm(?)?$ / [R=301,L]
# SEF URLs
SetEnv SEF_REQUEST false
RewriteRule ^[a-zd-]+/[a-z]d+/? /index.cfm/$0 [NC,PT,QSA,E=SEF_REQUEST:true]
RequestHeader add SEF-Request %{SEF_REQUEST}e
RewriteCond %{HTTP:SEF_REQUES} ^true$ [NC]
RewriteRule . - [L]
# Remove trailing ?
RewriteCond %{THE_REQUEST} ? HTTP [NC]
RewriteRule .? ^%{REQUEST_URI}? [R=301,L]
注意:我在发帖之前确实在网上/stackoverflow 上搜索过，但没有找到解决我的问题的方法.
NOTE: I did search online/stackoverflow before posting and did not find a solution to my problem.
我还注意到我的 RewriteRule ^index.cfm(?)?$/[R=301,L] 正在删除 index.cfm，即使它不是 url 中的最后一件事，导致 404我试着搜索一些东西(www.example.com/index.cfm?term=test)如果有人能纠正我并解释那会很棒.谢谢你.
Also I noticed that my RewriteRule ^index.cfm(?)?$ / [R=301,L] is removing the index.cfm even if it's not the last thing in the url resulting in a 404 when i try searching something (www.example.com/index.cfm?term=test) If someone could correct me and EXPLAIN that would be great. Thanks you.
不应重定向 www.example.com/index.cfm?term=test&a=dh&j=dhjsi.www.example.com/a/b/d/f/h/w/d 不应重定向.www.example.com/index.cfm?和 www.example.com/index.cfm 应该被重定向到 www.example.com.
www.example.com/index.cfm?term=test&a=dh&j=dhjsi should NOT be redirected. www.example.com/a/b/d/f/h/w/d should not be redirected. www.example.com/index.cfm? and www.example.com/index.cfm should be redirected to www.example.com.
推荐答案
RewriteCond %{THE_REQUEST} ? HTTP [NC]
RewriteRule .? ^%{REQUEST_URI}? [R=301,L]
不会工作，因为 ? 是正则表达式的保留字符，您需要将它与空格一起转义.试试:
Isn't going to work, because ? is a reserved character for regular expressions and you'd need to escape it along with the space. Try:
RewriteCond %{THE_REQUEST} ? HTTP [NC]
RewriteRule ^/?(index.cfm)? /? [R=301,L]
此外，您希望此规则在 # remove trailing index.cfm 规则下，而不是在最底部.
Additionally, you want this rule under your # remove trailing index.cfm rule, and not at the very bottom.
