IOS应用内支付返回新旧Receipt适配的方法

我是靠谱客的博主儒雅萝莉，最近开发中收集的这篇文章主要介绍IOS应用内支付返回新旧Receipt适配的方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

ios7.0后ios支付成功返回的票据Receipt的获取方式有了新的方式，

原来的SKPaymentTransaction中的transactionReceipt属性获取票据的方式已经过期，虽然还能使用，但是苹果官方建议使用新的

新版的获取Receipt的方式是通过新接口如下

NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];

当然，低于ios7.0的还是需要使用老版本接口，对两种版本进行适配的代码如下：

NSData*receipt= nil；
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")){
//ios after 7.0
  NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
  receipt = [NSData dataWithContentsOfURL:receiptURL];
  NSString *receiptURLStr = [receiptURL absoluteString];
  NSRange rangeSandbox = [receiptURLStr rangeOfString:@"sandbox"];
  if (rangeSandbox.location != NSNotFound){
    record[kIAPEnvironment] = [NSNumber numberWithInt:1];
  }
}else{
//ios 3.0~7.0
  receipt = transaction.transactionReceipt;
  NSDictionary *dict = [NSDictionary dictionaryWithContentsOfData:receipt];
  if (dict){
    NSString *env = [dict objectForKey:@"environment"];
    if ([env isEqualToString:@"Sandbox"]) {
      record[kIAPEnvironment] = [NSNumber numberWithInt:1];
    }
 }
}

判断是否是沙盒支付，新版本可以直接判断receiptURL中是否存在“sandbox“

老版本receipt可以解析NSData 查看environment是否为Sandbox来判断

+ (NSDictionary *)dictionaryWithContentsOfData: (NSData *)data{
  CFPropertyListRef plist = CFPropertyListCreateFromXMLData(kCFAllocatorDefault, (__bridge CFDataRef)data,
  kCFPropertyListImmutable, NULL);
  if(plist == nil) return nil;
  if ([(__bridge id)plist isKindOfClass:[NSDictionary class]]){
  return (__bridge NSDictionary *)plist;
  }else{
  CFRelease(plist);
  return nil;
  }
}

客户端receipt验证方式：

NSError *error;
NSDictionary *requestContents = @{
@"receipt-data": [receipt base64EncodedString]
};
NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents
options:0
error:&error];
if (!requestData) {
  return;
}
// Create a POST request with the receipt data.
NSURL *storeURL = [NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"];//根据是否是沙盒支付验证取正确的地址
NSMutableURLRequest *storeRequest = [NSMutableURLRequest requestWithURL:storeURL];
[storeRequest setHTTPMethod:@"POST"];
[storeRequest setHTTPBody:requestData];
// Make a connection to the iTunes Store on a background queue.
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:storeRequest queue:queue
completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
  if (connectionError) {
  /* ... Handle error ... */
} else {
  NSError *error;
  NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data   options:0 error:&error];
  if (!jsonResponse) { /* ... Handle error ...*/ }
  /* ... Send a response back to the device ... */
  }
}];

老版本返回格式：

{
bid = "com.coodezhang.test";
bvrs = "1.0";
"item_id" = 892617314;
"original_purchase_date" = "2017-12-14 07:43:14 Etc/GMT";
"original_purchase_date_ms" = 1626147394550;
"original_purchase_date_pst" = "2017-12-14 12:43:14 America/Los_Angeles";
"original_transaction_id" = 1000001127239959;
"product_id" = "com.coodezhang.test_coins99M_Tier1";
"purchase_date" = "2017-12-14 07:43:14 Etc/GMT";
"purchase_date_ms" = 1626147394550;
"purchase_date_pst" = "2017-12-14 12:43:14 America/Los_Angeles";
quantity = 1;
"transaction_id" = 1000001127239959;
"unique_identifier" = 0000b0124819;
"unique_vendor_identifier" = "ASDGF2DB-DSAD-5A21-9611-642A4B9CASDE7";
};
status = 0;
}

新版本返回格式：

{
environment = Sandbox;
receipt =   {
"adam_id" = 0;
"app_item_id" = 0;
"application_version" = 1;
"bundle_id" = "com.coodezhang.test";
"download_id" = 0;
"in_app" =     (
{
"is_trial_period" = false;
"original_purchase_date" = "2017-12-14 07:18:56 Etc/GMT";
"original_purchase_date_ms" = 1513235936000;
"original_purchase_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";
"original_transaction_id" = 1000000359369424;
"product_id" = "com.coodezhang.test_coins99M_Tier1";
"purchase_date" = "2017-12-14 07:18:56 Etc/GMT";
"purchase_date_ms" = 1513235936000;
"purchase_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";
quantity = 1;
"transaction_id" = 1000000359369424;
}
...... 可能存在多条
);
"original_application_version" = "1.0";
"original_purchase_date" = "2013-08-01 07:00:00 Etc/GMT";
"original_purchase_date_ms" = 1375340400000;
"original_purchase_date_pst" = "2013-08-01 00:00:00 America/Los_Angeles";
"receipt_creation_date" = "2017-12-14 07:18:56 Etc/GMT";
"receipt_creation_date_ms" = 1513235936000;
"receipt_creation_date_pst" = "2017-12-13 23:18:56 America/Los_Angeles";
"receipt_type" = ProductionSandbox;
"request_date" = "2017-12-14 07:19:23 Etc/GMT";
"request_date_ms" = 1513235963829;
"request_date_pst" = "2017-12-13 23:19:23 America/Los_Angeles";
"version_external_identifier" = 0;
};
status = 0;
}

值得注意的是，新版中数据结构中的in_app字段，可能包含多个transaction的receipt。当完成transaction后，还没有成功调用读取过receipt的接口，那下一次读取recept时会把所有的都读取出来，从而出现多条数据。

一般开发商app支付都有自己的支付系统，可能每次下单之前都会创建自己的订单号，需要与ios支付后返回的receipt一一对应，这种情况下如何处理还需要注意。
