micropay (提交刷卡支付)

WeixinPay supports REST.

#order_code build 32bit uuid
order_code = SecureRandom.uuid.tr('-', '')

WeixinPay::Pay.micrpay({
  attach: "微信刷卡支付",
  body: "购买商品",
  device_info: '88888888',
  out_trade_no: order_code,
  spbill_create_ip: '127.0.0.1',
  total_fee: 1,
  auth_code: 'xxxxxxxxxxxxxxxxxxx' #scan by scaner from weixin QR (扫描枪扫描微信二维码所获得)
})

WeixinPay::Pay.micrpay params will create an payment request and return a WeixinPay::Result instance(subclass of Hash) contains parsed result.

The result would be like this.

result = WeixinPay::Pay.micrpay({
  ...
  ...
})

result.raw
