ruby实现支付宝手机网页支付

本文旨在介绍如何完成在应用Ruby开发的网站(非Rails亦可)内集成支付宝的手机网页支付功能.

 

1.安装GEM包:

 

gem 'alipay_mobile', :github => 'https://github.com/oldfritter/alipay_mobile'

 2.配置

 

 

AlipayMobile.pid = 'YOUR_PID'
AlipayMobile.key = 'YOUR_KEY'
AlipayMobile.seller_email = 'YOUR_SELLER_EMAIL'

 3.完成支付业务

options = {req_id: orders.first.payment_sn, format: 'xml', v: '2.0', sec_id: 'MD5'}
options[:req_data] = "<direct_trade_create_req><subject>#{orders.collect{|order|order.subject}.join(",").gsub(' ','')}</subject><out_trade_no>#{orders.first.out_trade_no}</out_trade_no><total_fee>#{orders.collect{|order|order.order_total_price}.sum}</total_fee><seller_account_name>#{Alipay.seller_email}</seller_account_name><call_back_url>#{orders.first.call_back_url{payment = 'alipay_mobile'}}</call_back_url><notify_url>#{orders.first.notify_url{payment = 'alipay_mobile'}}</notify_url><out_user>#{orders.first.out_user}</out_user><merchant_url>#{orders.first.merchant_url{payment = 'alipay_mobile'}}</merchant_url><pay_expire>3600</pay_expire><payment_type>1</payment_type></direct_trade_create_req>"

#获取token:
url = AlipayMobile::Service.mobile_web_instant_credit_authorization(options)
@token = open(url) {|resp|return Nokogiri::HTML(URI.unescape resp.read).css('request_token').text}


#交易
options = {
    service: 'alipay.wap.auth.authAndExecute',
    _input_charset: 'utf-8',
    partner: AlipayMobile.pid,
    seller_email: AlipayMobile.seller_email,
    req_id: orders.first.payment_sn, 
    format: 'xml', 
    v: '2.0', 
    sec_id: 'MD5'
}           
options[:req_data] = "<auth_and_execute_req><request_token>#{@token}</request_token></auth_and_execute_req>"

payment_url = AlipayMobile::Service.mobile_web_instant_credit_transaction_url(options)
redirect_to payment_url

 4.验证支付宝的返回

# This is a action in the controller.
def alipay_mobile_notify
    return false unless AlipayMobile::Notify.verify? params
    nokogiri = Nokogiri::XML params['notify_data']
    payment_history = PaymentHistory.where(payment_sn: nokogiri.css('out_trade_no').text).first # PaymentHistory is a Model in my project.
    if nokogiri.css('trade_status').text == 'TRADE_FINISHED' || nokogiri.css('trade_status').text == 'TRADE_SUCCESS'
        .....your code....
    end
    render text: 'success' # Here must return 'success'.
end
