Installation

1. Follow the default way of set-up a payment module for Drupal Commerce, take a look at commerce_paypal installation if you don't understand.
2. Configure Wechat payment (only for Merchat pay - 公众号支付)

   Set an authorized URL alias in Wechat back-office, image example

   在微信公众平台的后台，将如下地址设置为一个支付授权目录, 图片示例

   http://YOUR_DOMAIN.COM/ALIAS_TO_DRUPAL_ROOT/commerce_wechatpay/checkout/

Payment methods

• Merchant pay (jsapi)(公众号支付)

  Requires opening payment page in Wechat browser, otherwise will return error. This method is good when developing all-browse-in-wechat web page.

• QR code pay (native)(扫码支付)

  (本模块使用的是扫码支付的支付模式二，所以无需设置扫码支付的支付回调URL)

  (This module uses wechat scan&pay mode 2, so no need to set redirect URL on scan&pay settings area)

  Provides a QR code image when going to the off-site payment gateway, allows user to scan the QR code and pay directly in Wechat. If opening payment page in Wechat browser, user can long-press the QRcode to pay (wechat build-in feature) but will not be returned back to successful page.

API docs

Overwrite main class handler

use the API to change to your class first

    function YOUR_MODULE_commerce_wechatpay_class_name_alter(&$class_name) {
      $class_name = 'YOUR_OWN_HANDLER_CLASS';
    }

then define your class, it's recommand if you extend from the original class

    Class YOUR_OWN_HANDLER_CLASS extends CommerceWechatpay {
      public function orderId2outTradeNo ($order_num)
      {
        // I want my own way for transfering order_id to out_trade_no
        return md5('some_secret_string'.md5($order_num));
      }

      // other overwritten, blabla
    }

Overwrite javascript process handler

use the API to change to your js process handler first

    function YOUR_MODULE_commerce_wechatpay_javascript_handler_name_alter(&$js_function_name) {
      $js_function_name = 'YOUR_OWN_JS_HANDLER_FUNCTION';
    }

then define your javascript function

    window.YOUR_OWN_JS_HANDLER_FUNCTION = function(configs, return_success_url, return_failure_url)
    {
      // some overwritten, blabla
    }
