An unofficial cmb (China Merchants Bank) pay ruby gem, inspired from alipay, wx_pay and cmbchina a lot.

• Payment URL generation for Web, App and WAP(Mobile Web).
• CMB Bank notification payment callback parse and verify.
• Direct refund API.
• Single order query.
• Multi orders query by transact/merchant date/settled date.

Add this line to your application's Gemfile:

gem 'cmb_pay'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cmb_pay

Create config/initializers/cmb_pay.rb and put following configurations into it.

# required
CmbPay.branch_id = '0755'     # 支付商户开户分行号，4位
CmbPay.co_no = '000056' # 支付商户号/收单商户号，6位长数字，由银行在商户开户时确定
CmbPay.co_key = ''            # 商户校验码/商户密钥，测试环境为空，注意保密
CmbPay.environment = 'test' if Rails.env.development? || Rails.env.staging?
# only require by uri_of_pre_pay_euserp
CmbPay.mch_no = 'P0019844'    # 协议商户企业编号，或者说是8位虚拟企业网银编号
CmbPay.default_payee_id = '1' # 默认收款方的用户标识
# onlyl require if you need refund via cmb_pay (no need if you using CMB bank web)
CmbPay.operator = '9999'      # 操作员号，一般是9999
CmbPay.operator_password = '' # 操作员的密码，默认是支付商户号，但建议修改，注意保密，仅直连退款需要
