之前一个项目做的代码全部不见了，过了一段时间后想拿来用，发现早己不了，不得己，摸了半天才弄成功了，汗，不是做IOS开发的，见笑。
1、   在IOS前端拿到的收据（Receipt）格式是:

--------------------------分割线------------------------------------------------------

这是购买成功后，app store发回来的收据，我们需要把这个收据发给第三方服务器（我们的服务器）去验证。

2、在跟苹果服务器作二次验证之前，需要将上面的这个原始收据用base64编码过，然后组装成JOSN格式：

{"receipt-data":"base64编码过后的代码"}

* 沙箱   https://sandbox.itunes.apple.com/verifyReceipt
* 真正的地址   https://buy.itunes.apple.com/verifyReceipt

3、苹果服务器返回的格式也是一个JSON格式，拿到里面返回的值“status”，若为0 说明验证成功。

若成功，还会返回收据支付信息内容，格式如下:

{"original_purchase_date_pst":"2014-02-12 00:45:53 America/Los_Angeles","purchase_date_ms":"1392194753368","unique_identifier":"f71c804bcd090085d17cf07e2805c1b0dfa053ea","original_transaction_id":"1000000101265551","bvrs":"1.0","transaction_id":"1000000101265551","quantity":"1","unique_vendor_identifier":"F63E7A35-0406-445F-A5AA-CC9974D4CA9B","item_id":"802793352","product_id":"com.ycm.pnm.wi1","purchase_date":"2014-02-12 08:45:53 Etc/GMT","original_purchase_date":"2014-02-12 08:45:53 Etc/GMT","purchase_date_pst":"2014-02-12 00:45:53 America/Los_Angeles","bid":"com.ycm.pnm","original_purchase_date_ms":"1392194753368"}
