需求是这样的，需要登录带验证码的网站，获取数据，但是不可能人为一直去记录数据，想通过自动采集的方式进行，如下是试验出来的结果代码！有需要的可以参考下！
<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller

{
$this->display();
}

foreach($this->cookieName as $key => $name)
{
$this->cookiePathFile[] = ROOT_PATH . $this->cookiePath . $this->cookieName[$key] . '_xxx.txt';
}
}

登录以后，就可以使用带cookie的访问其他页面了！
