php -d memory_limit=-1 `which composer` require yansongda/pay -vvv

notes ： because php There's a memory limit , It will affect composer download , So the above is to remove the memory limit , At the same time, download the payment extension （ My local environment has been modified php Invalid configuration , So in this way ）

3：composer download simplesoftwareio/simple-qrcode QR code expansion package

php -d memory_limit=-1 `which composer` require simplesoftwareio/simple-qrcode 1.3.0

notes ： Because the payment expansion package , Only QR code content will be generated （ Computer scanning code for payment ）, The QR code image will not be returned directly , So you need to download the expansion package for generating QR code images

4： Configure payment related information

Alipay scan code payment , example ：

    public function index()
    {
    
        // Order information 
        $order = [
            'out_trade_no' => time(),
            'total_amount' => '1',
            'subject' => 'test subject -  test ',
        ];

        // Generate QR code content 
        $result = Pay::alipay($this->config)->scan($order);
        // Generate a QR code picture from the content by extension 
        $generator = new Generator;
        $img = $generator->format('svg')
                ->size(190)->errorCorrection("L")
                ->generate($result->qr_code);
        return $img;
