Ruby wapper for Unionpay(银联支付)'s Open API.

Installation

Add this line to your application's Gemfile:

gem 'unionpay_open'
# or
gem 'unionpay_open', :git => 'git://github.com/yanyingwang/unionpay_open.git'

And then execute:

$ bundle

Or install it yourself as:

$ gem install unionpay_open

Usage

配置

UnionpayOpen.config do |unionpay|
  unionpay.pfx_file = 'tmp/acp.pfx'
  unionpay.pfx_file_password = '000000'
  unionpay.ca_file = 'tmp/acp.cer'
  unionpay.merchant_no = '111111111111111'

  # unionpay.env = 'production'     # 默认值为'development'，其可自动识别rack环境。
                                    # 如： ENV['RACK_ENV']如果为'production'，此gem则会自动加载为production环境。
                                    # 可通过`UnionpayOpen.env`来检查确定Gem当前使用的环境。
                                    # 此值的设定，主要影响`UnionpayOpen.endpoint`的值，即请求的银联网关地址。

end

查看

配置载入完成后，可以通过如下命令查看配置文件内容：

UnionpayOpen.env
UnionpayOpen.endpoint

UnionpayOpen.pfx_file
UnionpayOpen.merchant_no

UnionpayOpen.pkcs12
UnionpayOpen.pkcs12.to_s

UnionpayOpen.x509_certificate.public_key.to_s
UnionpayOpen.x509_certificate.serial.to_s

单位转换

银联接口总额使用分做单位，可以如如下方法转换：

# 10000分 = 100元
UnionpayOpen.fen2yuan(10000)


# 100.1元 = 10010分
UnionpayOpen.yuan2fen(100.1)

前台交易请求地址（默认为支付，即txnType = 01）

response = UnionpayOpen::Wap.front_trans_req( front_url: 'http://test.com',
											  order_id: "abcd1qaz",
											  txn_amt: "10000" )
# response 正常情况将输入银联请求结果，为HTML页面代码。

后台交易请求地址（默认为退货，即txnType = 04）

response = UnionpayOpen::Wap.back_trans_req( backUrl: 'http://test.com',
                                             orderId: "abcd1qaz",
                                             origQryId: "201509151115244444444",
                                             txnAmt: "10000" )

注意：

1. 方法名支持按照ruby规范，用snake方式（下划线连接单词）书写，Gem会在内部自动进行转换以适应银联接口。

2. 调用Gem时传入的参数默认只需包含必要字段(如front_trans_req只需front_url, order_id, txn_amt)，其他字段如果也作为参数传入，将覆盖UnionpayOpen内部已经默认定义的值。

3. debug需要，可在方法后添加一个block，来查看请求到银联的参数，如下示例代码：

# 查看其他字段默认值：
UnionpayOpen::Wap.front_trans_req {}

# 查看请求到银联接口的全部参数：
UnionpayOpen::Wap.front_trans_req( front_url: 'http://test.com',
											  order_id: "abcd1qaz",
											  txn_amt: "10000" ) {}

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
