Nginx：根据某些条件拒绝请求

在Apache中，我有一堆规则来阻止某些不需要的请求。

# Block libwww-perl/5.805 from attempting to exploit security vulnerabilities RewriteCond %{HTTP_USER_AGENT} ^libwww\-perl/.+ [NC] RewriteCond %{QUERY_STRING} . RewriteRule . - [F,L] # Block generic Java-based clients RewriteCond %{HTTP_USER_AGENT} ^Java/1\.6\.0_04 [NC] RewriteRule . - [F,L] # Block generic Mozilla clients RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0$ [NC] RewriteRule . - [F,L] 

什么是在nginx中完成同样任务的最有效的方法？

 # Block libwww-perl/5.805 from attempting to exploit security vulnerabilities if ($http_user_agent ~* ^libwww\-perl/.+) { if ($query_string ~ \.) { return 403; } } # Block generic Java-based clients if ($http_user_agent ~* ^Java/1\.6\.0_04) { return 403; } # Block generic Mozilla clients if ($http_user_agent ~* ^Mozilla/5\.0$) { return 403; }
