php生成二维码

• 基于thinkphp3.2的代码

use Vendor\Func\Func;
use Vendor\Func\Http;
use Vendor\Func\Red;
use Vendor\phpqrcode\phpqrcode;
use Vendor\Qiniu\Qiniu;

    public function test()
    {
        $selfhost = Func::getSelfHost();
        vendor('phpqrcode.phpqrcode');
        $value = $selfhost . '#/pages/index/reg?rec_code=123456';
        $errorCorrectionLevel = 'H';//纠错级别：L、M、Q、H
        $matrixPointSize = 10;//二维码点的大小：1到10,手机端一般是4
        $QR_name = $_SERVER['DOCUMENT_ROOT'] . '/site_upload/ping.jpg';
        \QRcode::png($value, $QR_name, $errorCorrectionLevel, $matrixPointSize );

        $qiniu = new Qiniu();
        $img   = $QR_name;

        $ext   = pathinfo($img, PATHINFO_EXTENSION);
        $name  = C('DB_NAME') . '_' .time() . mt_rand() . '.' . $ext;
        $s     = $qiniu->up($img, $name, C('QINIU.BUCKET'));

        $add_img = C('CDN_HOST') . $s['key'];
        echo $add_img;
       
    }
