PHP curl模拟登录带验证码的网站

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！

<?phpnamespace 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
