微信扫码登录
oauth原理：
下面是具体实现：
先发起请求
下面是控制器 ：
public function oauth() {
$this->uid && $this->member_msg(fc_lang('请退出后再登录'), $_SERVER['HTTP_REFERER']);
$appid = $this->input->get('id');
$oauth = require WEBPATH.'config/oauth.php';

// die;

// var_dump($code);
// echo $code;
$MEMBER = $this->get_cache('member');
// var_dump($MEMBER);
// die;
