如何查看PayPal过期订阅

Question

我正在开发网站，用户将获得一些付费内容。在这种情况下，我正在使用PayPal订阅。我成功订阅并希望获得订阅到期日期。我正在使用GetRecurringPaymentsProfileDetails方法获取有关订阅的信息。这是这种方法的结果：

`array (size=45)
  'PROFILEID' => string 'I-DLUN4G0R3G0F' (length=14)
  'STATUS' => string 'Active' (length=6)
  'AUTOBILLOUTAMT' => string 'NoAutoBill' (length=10)
  'DESC' => string 'Monthly subscription' (length=20)
  'MAXFAILEDPAYMENTS' => string '3' (length=1)
  'SUBSCRIBERNAME' => string 'blah-blah-blah' (length=14)
  'PROFILESTARTDATE' => string '2015-09-08T07:00:00Z' (length=20)
  'NEXTBILLINGDATE' => string '2015-09-08T10:00:00Z' (length=20)
  'NUMCYCLESCOMPLETED' => string '0' (length=1)
  'NUMCYCLESREMAINING' => string '0' (length=1)
  'OUTSTANDINGBALANCE' => string '0.00' (length=4)
  'FAILEDPAYMENTCOUNT' => string '0' (length=1)
  'TRIALAMTPAID' => string '0.00' (length=4)
  'REGULARAMTPAID' => string '0.00' (length=4)
  'AGGREGATEAMT' => string '0.00' (length=4)
  'AGGREGATEOPTIONALAMT' => string '0.00' (length=4)
  'FINALPAYMENTDUEDATE' => string '1970-01-01T00:00:00Z' (length=20)
  'TIMESTAMP' => string '2015-09-08T10:55:59Z' (length=20)
  'CORRELATIONID' => string 'fb5da7dc8451f' (length=13)
  'ACK' => string 'Success' (length=7)
  'VERSION' => string '86.0' (length=4)
  'BUILD' => string '17972692' (length=8)
  'BILLINGPERIOD' => string 'Month' (length=5)
  'BILLINGFREQUENCY' => string '1' (length=1)
  'TOTALBILLINGCYCLES' => string '0' (length=1)
  'CURRENCYCODE' => string 'GBP' (length=3)
  'AMT' => string '9.99' (length=4)
  'SHIPPINGAMT' => string '0.00' (length=4)
  'TAXAMT' => string '0.00' (length=4)
  'REGULARBILLINGPERIOD' => string 'Month' (length=5)
  'REGULARBILLINGFREQUENCY' => string '1' (length=1)
  'REGULARTOTALBILLINGCYCLES' => string '0' (length=1)
  'REGULARCURRENCYCODE' => string 'GBP' (length=3)
  'REGULARAMT' => string '9.99' (length=4)
  'REGULARSHIPPINGAMT' => string '0.00' (length=4)
  'REGULARTAXAMT' => string '0.00' (length=4)
`

如上所示，我有NEXTBILLINGDATE字段，我认为这就是我所需要的。问题是该字段显示的时间不正确。根据我的NEXTBILLIGDATE和REGULARBILLINGPERIOD字段，REGULARBILLINGFREQUENCY似乎应该像2015-10-08T07：00：00Z。此外，也许有人知道如何测试过期的订阅？或者如何过期订阅，PayPal沙盒中是否有任何工具？希望在这里找到解决方案。感谢
