删除尾随的问号htaccess的 [英] Removing trailing question mark with htaccess

问题描述

有人可以帮助我了解这个code？

 ＃删除尾随？
的RewriteCond％{} THE_REQUEST？ HTTP [NC]
重写规则？ /％{REQUEST_URI}？ [R = 301，L]
 

基本上我有一个网站www.example.com正在生成一个链接到www.example.com/index.cfm~~V？我需要它重定向到www.example.com的搜索引擎优化复制的目的。我设法去除index.cfm但？还停留在那里（www.example.com/？）。如果它是最后一个字符的斜线也被删除就好了。我发现这条规则在网上，但我得到一个的RewriteCond：坏标志符。警报在Apache中，并没有做任何事情。

我也有一些网页一样www.example.com/index.cfm?term=test用于搜索，所以我只是想摆脱尾随的问号，而不是当我有连接到它的查询。

该错误是在RewriteCond指令。我需要帮助了解情况，为什么它不工作，不只是它的答案。

以防万一这里是整个htaccess的：

  RewriteEngine叙述上
的RewriteBase /

＃删除尾随index.cfm
重写规则^ index.cfm（\？）？$ / [R = 301，L]

＃海基会网址
SETENV SEF_REQUEST假
重写规则^ [A-Z \ D \  - ] + / [A-Z] \ D + /？ /index.cfm/$0 [NC，PT，QSA，E = SEF_REQUEST：真]
RequestHeader添加海基会请求％{SEF_REQUEST} e所
的RewriteCond％{HTTP：SEF_REQUES} ^真$ [NC]
重写规则。 -  [L]

＃删除尾随？
的RewriteCond％{} THE_REQUEST？ HTTP [NC]
重写规则？ ^％{REQUEST_URI}？ [R = 301，L]
 

注：我张贴，并没有找到一个解决我的问题之前，没有在网上搜索/计算器

编辑：另外，我发现我重写规则^ index.cfm（\？）$ / [R = 301，L]被拆除index.cfm即使它不是导致404时的最后一件事的网址是什么？我尝试搜索的东西（www.example.com/index.cfm?term=test）如果有人可以纠正我，并解释说，将是巨大的。谢谢你。

EDIT2：www.example.com/index.cfm?term=test&a=dh&j=dhjsi不应该被重定向。 www.example.com/a/b/d/f/h/w/d不应被重定向。 www.example.com/index.cfm~~V？和www.example.com/index.cfm应该被重定向到www.example.com。

解决方案

 的RewriteCond％{} THE_REQUEST？ HTTP [NC]
重写规则？ ^％{REQUEST_URI}？ [R = 301，L]
 

是行不通的，因为？是正规EX pressions保留字符，你就需要逃避它随着空间。尝试：

 的RewriteCond％{THE_REQUEST} \？\ HTTP [NC]
重写规则^ /？（指标\ .CFM）？ /？ [R = 301，L]
 

此外，你要根据本条规则你的＃删除尾随index.cfm 规则，而不是在最底层。

Can someone help me understand this code?

# Remove trailing ?
RewriteCond %{THE_REQUEST} ? HTTP [NC] 
RewriteRule .? /%{REQUEST_URI}? [R=301,L]

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.

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.

The error is in the RewriteCond. I need help understanding the condition and why it doesnt work not just the answer to it.

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-z\d\-]+/[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]

NOTE: I did search online/stackoverflow before posting and did not find a solution to my problem.

EDIT: 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.

EDIT2: 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.

解决方案

RewriteCond %{THE_REQUEST} ? HTTP [NC] 
RewriteRule .? ^%{REQUEST_URI}? [R=301,L]

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]

Additionally, you want this rule under your # remove trailing index.cfm rule, and not at the very bottom.
