There's a pre-built Payment Gateway based on Omnipay at labs7in0/E-cash.
Omnipay is installed via Composer. To install, simply add it
to your composer.json file:
{
"require": {

}
}And run composer to update your dependencies:
$ curl -s http://getcomposer.org/installer | php
$ php composer.phar update
The following gateways are provided by this package:
- WeChat Express (WeChat NATIVE)
For general usage instructions, please see the main Omnipay repository.
The WeChat NATIVE payment gateway return a URI which can be opened within WeChat In-App broswer, you can generate a QR code with the URI.
$omnipay = Omnipay::create('WeChat_Express');
$omnipay->setAppId('app_id'); // App ID of your WeChat MP account
$omnipay->setAppKey('app_key'); // App Key of your WeChat MP account
$omnipay->setMchId('partner_id'); // Partner ID of your WeChat merchandiser (WeChat Pay) account
$params = array(
'out_trade_no' => time() . rand(100, 999), // billing id in your system
'notify_url' => $notify_url, // URL for asynchronous notify
'body' => $billing_desc, // A simple description
'total_fee' => 0.01, // Amount with less than 2 decimals places
'fee_type' => 'CNY', // Currency name from ISO4217, Optional, default as CNY
);
$response = $omnipay->purchase($params)->send();
$qrCode = new Endroid\QrCode\QrCode(); // Use Endroid\QrCode to generate the QR code
$qrCode
->setText($response->getRedirectUrl())
