问题描述

有没有办法通过 php 脚本阻止一些用户代理?mod_security 示例

there have a way to block some of user agent via php script? Example on mod_security

SecFilterSelective HTTP_USER_AGENT "Agent Name 1"
SecFilterSelective HTTP_USER_AGENT "Agent Name 2"

我们也可以通过示例使用 htaccess 或 robots.txt 阻止它们，但我想要在 php 中.有示例代码吗?

Also we can block them using htaccess or robots.txt by example but I want in php. Any example code?

推荐答案

我喜欢 @Nerdling 的回答，但如果它有帮助，如果您有很长的用户代理列表需要阻止:

I like @Nerdling's answer, but in case it's helpful, if you have a very long list of user agents that need to be blocked:

$badAgents = array('fooAgent','blahAgent', 'etcAgent');
foreach($badAgents as $agent) {
    if(strpos($_SERVER['HTTP_USER_AGENT'],$agent) !== false) {
        die('Go away');
    }
}

更好:

$badAgents = array('fooAgent','blahAgent', 'etcAgent');
if(in_array($_SERVER['HTTP_USER_AGENT'],$badAgents)) {
    exit();
}
