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 HomeController; use ThinkController; class LoginController extends Controller { protected $cookieName = array('cookie_verify', 'cookie_verify'); protected $cookiePath = '/cookie/'; protected $cookiePathFile = array(); public function index() { $this->display(); } public function _initialize(){ foreach($this->cookieName as $key => $name) { $this->cookiePathFile[] = ROOT_PATH . $this->cookiePath . $this->cookieName[$key] .

登录以后，就可以使用带cookie的访问其他页面了！
ps：php curl 登录淘宝
