代码实现

public function doMobilePhpqrcode()
    {
//        全局变量
        global $_W, $_GPC;
//        微信用户信息
        $userinfo = mc_oauth_userinfo($_W['uniacid']);
//生成二维码
        require IA_ROOT . '/addons/health_moniter/phpqrcode/qrlib.php';
        //生成二维码
//        QRcode::png('https://www.baidu.com');
        $url = "https://www.baidu.com";
        $value = $url;
        $errorCorrectionLevel = "L";
        $matrixPointSize = "4.3";
        $margin = "1";
//        判断二维码文件是否存在,如果存在就不写入
//        $file = IA_ROOT . '/addons/health_moniter/qrcode/' . $userinfo['openid'] . '.png';
//        if(!file_exists($file)){
//            QRcode::png($value, IA_ROOT . '/addons/health_moniter/qrcode/' . $userinfo['openid'] . '.png', $errorCorrectionLevel, $matrixPointSize, $margin);
//
//        }

        QRcode::png($value, HEALTH_MONITER_QRCODE . $userinfo['openid'] . '.png', $errorCorrectionLevel, $matrixPointSize, $margin);

        include $this->template('phpqrcode');
    }

HEALTH_MONITER_QRCODE是自己定义的常量
