paypal IPN and PDT 2

当支付模式为快速支付（按钮）时，IPN 和PDT都会起作用，当以Rest Api方式创建支付时， PDT是无效的，它应该是针对网站的，IPN依然起作用。调用Rest Api 付款的步骤是这样的：

1. 注册paypal账号，升级为高级或者企业账号;

2. 登录开发者中心后台，注册app;

3. 获取Client ID, Secret;

4. 设置ipn通知地址（profile里面设置）;

5. 获取paypal SDK，在sandbox环境测试, 支付返回的url是在调用代码里面设置的；

POST /v1/payments/payment

POST /v1/payments/payment/<Payment-Id>/execute

主要是这两个APi

6. 替换代码sandbox为正式url,上线。

需要注意的问题：

1.如果卖家退款，资金会立刻结算，并向paypal支付一定的手续费，程序会收到ipn通知；

2.如果买家提出争议，争议类型是未经授权的交易时，资金会立刻冻结，程序会收到ipn通知；

3.如果买家提出争议，争议类型不是未经授权的交易时，资金会立刻冻结，程序不会收到ipn通知；

4. 买家和卖家的唯一交易号是完全不一致的;

5.买家和卖家的发票号（账单号）是一致的;

6.支付返回的url所在的程序，收到的数据不可信，可以把一切本地的逻辑放在处理ipn的程序里面进行。ipn消息不是实时的，差不多秒级的延迟。

用户支付完成时，返回的url会收到如下请求数据：

'success' => 'true',
'paymentId' => 'PAY-1BV5911839643144YKSCUA7Q',
'token' => 'EC-8684120785130974D',
'PayerID' => 'JARYJK2TES6C6',

调用execute接口返回：
