.htaccess - RewriteCond:坏标记分隔符

Question

我正在使用.htaccess来阻止对我网站的一些不良请求.一切都在我的本地服务器(XAMPP)上按预期工作,但当我将其上传到主机(共享)时,我收到此错误:RewriteCond: bad flag delimiters

这是我的.htaccess中的代码

我删除了尾随空格和注释.仍然会收到此错误.

Answer 1

既然你知道问题是a RewriteCond,你可以通过消除一半条件然后测试剩下的条件来快速找到问题.

您可以从删除第一条规则开始.错误仍然存​​在.下一步删除剩余的RewriteConds 的前半部分(约20)并再次测试.继续,直到你到达少数RewriteConds并逐个删除它们.

该错误随着倒数第二个规则而消失.重新插入此规则以验证错误是否再次出现.现在看看

RewriteCond %{QUERY_STRING} (;|<|>|'|"|\)|%0A|%0D|%22|%27|%3C|%3E|%00).*(/\*|union|select|insert|drop|delete|update|cast|cre ate|char|convert|alter|declare|order|script|set|md 5|benchmark|encode) [NC,OR]

这种情况怎么了？你看到的空间cre ate和md 5？

一旦删除这些空格或用反斜杠转义它们\,错误就会消失.

正则表达式中有一些（可能）不需要的空格，这对我有用：
