.htaccess - RewriteCond：坏标记分隔符

Question

我正在使用.htaccess阻止对我的网站的一些不良请求。一切工作我的本地服务器（XAMPP）在如预期，但是当我上传到主机（共享）我得到这个错误：RewriteCond: bad flag delimiters

下面是在我的.htaccess代码

我已经删除了尾部空格和评论。仍然得到这个错误。

有一些（可能）在正则表达式不需要的空间，这是为我工作：

你既然知道这个问题是一个RewriteCond，你可以相当迅速消除一半定位问题的条件，然后测试剩下的。

您可以从删除第一条规则开始。错误依然存在。接下来的步骤是将剩余的RewriteCond s（约20）的前半部分删除并再次测试。继续进行，直到您遇到少数几个RewriteCond s并逐个将其移除。

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] 

这种情况有什么问题？你看到cre ate和md 5的空格吗？

只要您删除这些空格或用反斜杠\转义它们，错误就消失了。
