curl https://raw.githubusercontent.com/killbill/killbill-paypal-express-plugin/master/db/ddl.sql | mysql -h 127.0.0.1 -ukillbill -pkillbill killbill

•   安装Tomcat
•   Kill 初始化

killbill:
  version: 0.12.1
  webapp_path: /var/tmp/tomcat/webapps/ROOT.war
  plugins_dir: /var/tmp/bundles
  plugins:
    ruby:
      - name: paypal-express-plugin
        version: 1.8.1
      - name: stripe-plugin
        version: 1.0.0

kpm install kpm.yml

    Paypal setup

:paypal_express:
  :signature: 'your-paypal-signature'
  :login: 'your-username-facilitator.something.com'
  :password: 'your-password'
  :test: true

:database:
  :adapter: 'jdbcmysql'
  :jndi: 'killbill/osgi/jdbc'
  :connection_alive_sql: 'select 1'
  :pool: 25

    建立集成账户

curl -v \
     -X POST \
     -u admin:password \
     -H 'Content-Type: application/json' \
     -H 'X-Killbill-CreatedBy: admin' \
     -d '{"apiKey": "bob", "apiSecret": "lazar"}' \
     "http://127.0.0.1:8080/1.0/kb/tenants"

   接下来，就可以在应用中集成Kill了。示例如下

    建立账户，这个是假设在电商中已经存在账户，所以需要建立完以后，到Kill 中建立账户

curl -v \
     -u admin:password \
     -H "X-Killbill-ApiKey: bob" \
     -H "X-Killbill-ApiSecret: lazar" \
     -H "Content-Type: application/json" \
     -H "X-Killbill-CreatedBy: demo" \
     -X POST \
     --data-binary '{"name":"John Doe","email":"[email protected]","externalKey":"john-doe-1234","currency":"USD"}' \
     "http://127.0.0.1:8080/1.0/kb/accounts"

   将用户的paypal 账户集成到kill bill中

curl -v \
     -X POST \
     -u admin:password \
     -H 'Content-Type: application/json' \
     -H 'X-Killbill-ApiKey:bob' \
     -H 'X-Killbill-ApiSecret:lazar' \
     -H 'X-Killbill-CreatedBy: creator' \
     --data-binary '{
       "pluginName": "killbill-stripe",
       "pluginInfo": {
         "properties": [
           {
             "key": "token",
             "value": "t3GER3BP3JHLASZe"
           }
         ]
       }
     }' \
     "http://127.0.0.1:8080/1.0/kb/accounts/268983f2-5443-47e4-a967-b8962fc699c5/paymentMethods?isDefault=true"

   接下来可以使用Paypal 进行支付，首先需要在Paypal 中申请Token

curl -v \
     -X POST \
     -u admin:password \
     -H 'Content-Type: application/json' \
     -H 'X-Killbill-ApiKey:bob' \
     -H 'X-Killbill-ApiSecret:lazar' \
     -H 'X-Killbill-CreatedBy: creator' \
     --data-binary '{
       "kb_account_id": "13d26090-b8d7-11e2-9e96-0800200c9a66",
       "currency": "USD",
       "options": {
         "return_url": "http://www.google.com/?q=SUCCESS",
         "cancel_return_url": "http://www.google.com/?q=FAILURE",
         "billing_agreement": {
           "description": "Your subscription"
         }
       }
     }' \
     "http://127.0.0.1:8080/plugins/killbill-paypal-express/1.0/setup-checkout"

   获取token以后可以开始支付第二步

curl -v \
     -X POST \
     -u admin:password \
     -H 'Content-Type: application/json' \
     -H 'X-Killbill-ApiKey:bob' \
     -H 'X-Killbill-ApiSecret:lazar' \
     -H 'X-Killbill-CreatedBy: creator' \
     --data-binary '{
       "pluginName": "killbill-paypal-express",
       "pluginInfo": {
         "properties": [
           {
             "key": "token",
             "value": "EC-20G53990M6953444J"
           }
         ]
       }
     }' \
     "http://127.0.0.1:8080/1.0/kb/accounts/268983f2-5443-47e4-a967-b8962fc699c5/paymentMethods?isDefault=true"

    第三步：开始支付

curl -v \
     -u admin:password \
     -H "X-Killbill-ApiKey: bob" \
     -H "X-Killbill-ApiSecret: lazar" \
     -H "Content-Type: application/json" \
     -H "X-Killbill-CreatedBy: demo" \
     --data-binary '{"transactionType":"PURCHASE","amount":"10","currency":"USD"}' \
     "http://127.0.0.1:8080/1.0/kb/accounts/268983f2-5443-47e4-a967-b8962fc699c5/payments"
