iOS应用内购买的收据字符串解释 [英] iOS in-app purchase's receipt string explained

问题描述

我尝试了解从iTunes服务器获取的收据信息，但找不到相关文档。

I try to understand the receipt information obtained from iTunes server, but could not find relevant documentation.

特别是， unique_identifier ， unique_vendor_identifier 之间的区别是什么？ ， original_transaction_id （在WWDC'12会话中声称是事实上的客户ID）和 [[[UIDevice currentDevice] identifierForVendor] UUIDString] ？

Particularly, what's the difference among unique_identifier, unique_vendor_identifier, original_transaction_id (which is claimed, in a WWDC'12 session, to be a de facto customer id) and [[[UIDevice currentDevice] identifierForVendor] UUIDString]?

{"receipt":
    {"original_purchase_date_pst":"...",        
     "purchase_date_ms":"...", 
     "unique_identifier":"...", 
     "original_transaction_id":"...", 
     "bvrs":"...", 
     "transaction_id":"...", 
     "quantity":"...", 
     "unique_vendor_identifier":"...", 
     "item_id":"...", 
     "product_id":"...", 
     "purchase_date":"...", 
     "original_purchase_date":"...", 
     "purchase_date_pst":"...", 
     "bid":"...", 
     "original_purchase_date_ms":"..."},  
"status":0}`

我希望将此收据存储在我的服务器上的邮件跟踪订阅有效性。所以最好知道我应该使用哪个id作为用户身份的代理。

I wish to store this receipt information on my server to track subscription validity. So it is better to know which id I should use as a surrogate for user identity.

推荐答案

你的软件应该只依赖于Apple在其文档中描述的字段。他们可以随时删除unique_identifier或unique_vendor_identifier，更改其含义或更改其值，而无需告诉您。

Your software should only rely on the fields that Apple describes in their documentation. They could remove unique_identifier or unique_vendor_identifier, change their meaning, or change their values at any time without telling you about it.

您应该关注Apple的文档关于在服务器将sbuscription内容发送到设备之前使用Apple服务器验证订阅收据。

You should follow Apple's documentation in regard to verifying subscription receipts using Apple's servers before your server transmits the sbuscription content to the device.
