php扫码登录如何实现

PHP微信公众号扫码模拟登录功能

功能只是将：https://github测试数据/huanz/wechat-mp-hack 改成PHP实现罢了。

主要流程如下：

1、先访问https://mp.weixin.qq测试数据/，模拟登录，进入二维码页面。

2、带着返回的cookie下载二维码，程序后台一直while循环，等待扫描消息。

3、打开下载的二维码，微信扫码，登录成功，获取token和cookie，然后后面就可以自由发挥了。

} 

怎么调用？上码：

$arr = array(
  'account'  => '***',
  'password' => '****',
  'key'    => "tmall",
);
$w  =  new WeiSendAuto();
$w->init($arr);
if(!$w->getToken()){
  die("NOT TOKEN!");
}
