最近一直在做app內(nèi)購(gòu)買(mǎi)的項(xiàng)目, 簡(jiǎn)單總結(jié)一下.
準(zhǔn)備工作這里就不再贅述了, 主要講一下, 注意事項(xiàng), 大家有時(shí)會(huì)忽略, 后期可能造成特別大的溝通成本.
有興趣的同學(xué)也可以參考:https://github.com/Balopy/PurchaseInApp

交易結(jié)束時(shí), 需要向 iTunes Store 驗(yàn)證票據(jù)信息. 分為兩種, 這里我定義了兩個(gè)宏:

沙盒測(cè)試環(huán)境驗(yàn)證
#define SANDBOX @"https://sandbox.itunes.apple.com/verifyReceipt"
//正式環(huán)境驗(yàn)證
#define AppStore @"https://buy.itunes.apple.com/verifyReceipt"

- (void)completeTransaction:(SKPaymentTransaction *)transaction {
  
  //系統(tǒng)IOS7.0以后，驗(yàn)證返回的數(shù)據(jù)
    //得到的憑證只能使用 base64解碼,規(guī)則這么定的
    NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
    NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
    
    if (!receipt) {
        
        if (self.failTransaction) {
            
            self.failTransaction (@"交易失敗");
        }
        return;
    }
   
    // Create the JSON object that describes the request
    NSString *receiptCode = [receipt base64EncodedStringWithOptions:0];
    NSError *error;
    NSDictionary *requestContents = @{
                                      @"receipt-data": receiptCode
                                      };
    NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents options:0 error:&error];

    // Create a POST request with the receipt data.
    NSURL *storeURL = [NSURL URLWithString:AppStore];
    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) {//為空
               
                if (self.failTransaction) {
                    
                    self.failTransaction (@"驗(yàn)證失敗");
                }

            } else {
            
                [self checkPayForReciept:jsonResponse receipt:receiptCode];
            }
        }
    }];
    
    
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}

通過(guò)返回的 jsonResponse 數(shù)據(jù)中的 status, 做判斷, 驗(yàn)證票據(jù)信息, 是否正確
可參考官方文檔

        case 0: {//驗(yàn)證成功
