php模拟登陆抓取

此为在ci框架的抓取程序：

checklogin() ;
       var_dump($this->crab());
    }

    // 登录
    private function checklogin() {
        $curlPost = 'username=111&password=111';
        $con = $this->curl_post( 'http://127.0.0.1/phc/index/login',$curlPost,1 );
        return $con;
    }

    //抓取
    private function crab(){
        $con = $this->curl_post( 'http://127.0.0.1/phc/index/list','',2 );
        return $con;
    }

    //通信
    private function curl_post( $url,$curlPost,$method) {
        $cookie_file = dirname(__FILE__).'/cookie.txt';
        $ch = curl_init();//初始化curl
        curl_setopt( $ch, CURLOPT_URL, $url );//抓取指定网页
        curl_setopt( $ch, CURLOPT_HEADER, 0 );//设置header
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );//要求结果为字符串且输出到屏幕上
        curl_setopt( $ch, CURLOPT_POST, 1 ); //post提交方式
        curl_setopt( $ch, CURLOPT_POSTFIELDS, $curlPost );
        if($method == 1)
        curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
        else
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
        $data = curl_exec( $ch ); //运行curl
        curl_close( $ch );
        if($method != 1) return $data;
    }
}

此为phalcon登陆验证

session->has('userid')){
            exit("has login");
        }else{
            exit("no login");
        }
    }
    public function loginAction(){
        $username = $this->request->getPost('username');
        $password = $this->request->getPost('password');
        if($username == '111' && $password == '111'){
            $this->session->set('userid',23);
        }
        $this->view->disable();
    }
}
