IOS应用内支付返回新旧Receipt适配的方法

2019年07月24日  | 移动技术网移动技术  | 我要评论

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;

"product_id" = "com.coodezhang.test_coins99m_tier1";
"purchase_date" = "2017-12-14 07:43:14 etc/gmt";

...... 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;

"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。
