use Endroid\QrCode\RoundBlockSizeMode\RoundBlockSizeModeMargin;
use Endroid\QrCode\Writer\PngWriter;
 
class Article extends BaseController
{
   //生成pr code
    public function qr() {
        $writer = new PngWriter();
// Create QR code
        $qrCode = QrCode::create('https://www.iliangcang.com')
            ->setEncoding(new Encoding('UTF-8'))
            ->setErrorCorrectionLevel(new ErrorCorrectionLevelLow())
            ->setSize(300)
            ->setMargin(10)
            ->setRoundBlockSizeMode(new RoundBlockSizeModeMargin())
            ->setForegroundColor(new Color(0, 0, 0))
            ->setBackgroundColor(new Color(255, 255, 255));
 
// Create generic logo
        //logo是放在app/asset/目录下
        $logo = Logo::create(app()->getRootPath()."/app/asset/logo.png")
            ->setResizeToWidth(50);
 
// Create generic label
        $label = Label::create('良仓.生活美学')
            ->setTextColor(new Color(0, 0, 0));
 
        $result = $writer->write($qrCode, $logo, $label);
        header('Content-Type: '.$result->getMimeType());
        echo $result->getString();
        exit;
 
    }
}
