三、 客户端使用StoreKit完成内购
添加Storekit.Framework,编写自己的storeObsever,用于处理交易,代码如下,其中completeTransaction和failedTransaction两个函数是自定义的用来处理交易成功与失败其它的就都是SKPaymentTransactionObserver这个代理要求的。

四、验证store收据
交易完成后,服务器需要向Apple验证交易是否成功,不然,自己买的产品给别人了就亏了。
在上面的客户端代码中,我们监听函数中在交易成功时调用了completeTransaction函数,购买成功之后,我们会收到反馈的收据,其中在transactionReceipt中存验证信息。将字打印出来格式为:

将这个字符串发给服务器,然后用服务器去POST到App上去验证。
验证过程:( 原本是在服务器上验证的,为了测试,我们不弄太复杂,直接在当前程序做一个验证测试 )
1. 先取出transactionReceipt属性中的收据数据。并以base64方式编码

NSString* ObjectString = [self encode:(uint8_t *)transaction.transactionReceipt.bytes length:transaction.transactionReceipt.length];

// 其中encode就是base64编码转换函数,编码后的数据为类似:

2. 创建JSON对象,字典格式,单键值对,键名为”receipt-data“,值为上一步编码的数据
{”recipt-data“:"编码后数据"}

NSString* sendString = [[NSString alloc] initWithFormat:@"{\"receipt-data\":\"%@\"}",ObjectString ];

3. 发送HTTP POS 的请求,将数据发送到App Store,其地址为 https://buy.itunes.apple.com/verifyReceipt
sandbox测试地址为:https://sandbox.itunes.apple.com/verifyReceipt

NSURL *sandboxStoreURL = [[NSURL alloc] initWithString: @"https://sandbox.itunes.apple.com/verifyReceipt"];
NSData *postData = [NSData dataWithBytes:[sendString UTF8String] length:[sendString length]];
NSMutableURLRequest *connectionRequest = [NSMutableURLRequest requestWithURL:sandboxStoreURL];
[connectionRequest setHTTPMethod:@"POST"];
[connectionRequest setTimeoutInterval:120.0];
[connectionRequest setCachePolicy:NSURLRequestUseProtocolCachePolicy];
[connectionRequest setHTTPBody:postData];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];

NSURLConnection *connection = [[NSURLConnection alloc]
initWithRequest:connectionRequest
delegate:self];
[connection release];

4. App Store的返回值也是一个JSON格式的对象,包含两个键值对, status和receipt:
{
“status” : 0,
“receipt” : { … }
}

{"receipt":{"original_purchase_date_pst":"2013-08-04 04:15:45 America/Los_Angeles", "purchase_date_ms":"1375614945275", "unique_identifier":"0000b031c7b8", "original_transaction_id":"1000000082868664", "bvrs":"1.0", "transaction_id":"1000000082868664", "quantity":"1", "unique_vendor_identifier":"6CF88856-EF6F-4F7E-92F8-A5A022E77DEB", "item_id":"683919162", "product_id":"com.HelloStorTest.TestItem", "purchase_date":"2013-08-04 11:15:45 Etc/GMT", "original_purchase_date":"2013-08-04 11:15:45 Etc/GMT", "purchase_date_pst":"2013-08-04 04:15:45 America/Los_Angeles", "bid":"com.guoke.HelloStoreTest", "original_purchase_date_ms":"1375614945275"}, "status":0}

如果status的值为0, 就说明该receipt为有效的。 否则就是无效的。
 
App Store的收据
发送给App Store的收据数据是通过对transaction中对应的信息编码而创建的。 当App Store验证收据时, 将从其中解码出数据,并以”receipt”的键返回。 返回的响应信息是JSON格式,被包含在SKPaymentTransaction的对象中(transactionReceipt属性)。Server可通过这些值来了解交易的详细信息。 Apple建议只发送receipt数据到服务器并使用receipt数据验证和获得交易详情。 因为App Store可验证收据信息,返回信息,保证信息不被篡改,这种方式比同时提交receipt和transaction的数据要安全。
 
购买信息的键,很多的键都对应SKPaymentTransaction的属性。
键名  描述
quantity  购买商品的数量。对应SKPayment对象中的quantity属性
product_id  商品的标识,对应SKPayment对象的productIdentifier属性。
transaction_id  交易的标识,对应SKPaymentTransaction的transactionIdentifier属性
purchase_date  交易的日期,对应SKPaymentTransaction的transactionDate属性
original_-transaction_id  对于恢复的transaction对象,该键对应了原始的transaction标识
original_purchase_-date  对于恢复的transaction对象,该键对应了原始的交易日期
app_item_id  App Store用来标识程序的字符串。一个服务器可能需要支持多个server的支付功能,可以用这个标识来区分程序。链接sandbox用来测试的程序的不到这个值,因此该键不存在。
version_external_-identifier  用来标识程序修订数。该键在sandbox环境下不存在
bid iPhone 程序的bundle标识
bvrs iPhone 程序的版本号
