Class Method Details

.generate(random: nil, strkey:, date:, branch_id:, co_no:, bill_no:, amount:, merchant_para:, merchant_url:, payer_id:, payee_id:, client_ips: nil, goods_type: nil, reserved: nil) ⇒ Object

产生商户校验码

  • random - 随机数

  • strkey - 商户密钥

  • date - 订单日期

  • branch_id - 开户分行号

  • co_no - 商户号

  • bill_no - 订单号

  • amount - 订单金额

  • merchant_para - 商户自定义参数

  • merchant_url - 商户接受通知的URL

  • payer_id - 付款方用户标识。用来唯一标识商户的一个用户。长度限制为40字节以内。

  • payee_id - 收款方的用户标识。生成规则同上。不要求商户提供用户的注册名称，但需要保证一个用户对应一个UserID。

  • client_ips - 商户取得的客户端IP，如果有多个IP用逗号‘,’分隔。长度限制为64字节。

  • goods_type - 商品类型编码，长度限制为8字节。

  • reserved - 保留字段，长度限制为1024字节。
